Contraindications of periodontal flap surgery. The main objective of periodontal flap surgical procedures is to allow access for the cleaning of the roots of teeth and the removal of the periodontal pocket lining, as well as to treat the irregularities of the alveolar bone, so that when gingiva is repositioned around the teeth, it will allow for the reduction of pockets, infections, and inflammation. It does not attempt to reduce the pocket depth, but it does eliminate the pocket lining. Root planing is done followed by osseous surgery if needed. Contents available in the book .. Apically displaced flap can be done with or without osseous resection. ), Only gold members can continue reading. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. Loss of marginal bone as a result of uncovering the osseous crest. Later on Cortellini et al. Following are the steps followed during this procedure. Connective tissue grafting harvesting techniques as well as free gingival graft. This flap procedure causes the greatest probing depth reduction. Short anatomic crowns in the anterior region. 2. The area is re-inspected for any remaining granulation tissue, tissue tags or deposits on the root surfaces. Contents available in the book . Both full-thickness and partial-thickness flaps can also be displaced. Gain access for osseous resective surgery, if necessary, 4. This is especially important in maxillary and mandibular anterior areas which have a prime esthetic concern. This is also known as. The area to be operated is irrigated with an antimicrobial solution and isolated. Conventional surgical approaches include the coronal flap, direct cutaneous incision, and endoscopic techniques. The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. . The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Journal of clinical periodontology. (1985) 26 modified this procedure to preserve anterior esthetics after flap surgery. The bleeding may range from a minor leakage or oozing, to extensive or frank bleeding at the surgical site. After this, the second incision or the sulcular incision is made from the bottom of the pocket to the crest of the alveolar bone. Swelling is another common complication after flap surgery. Persistent inflammation in areas with moderate to deep pockets. Historically, gingivectomy was the treatment of choice for these areas until 1966, when Robinson 32 addressed this problem and gave a separate surgical procedure for these areas which he termed distal wedge operation. Contents available in the book .. 15c or No. Areas where post-operative maintenance can be most effectively done by doing this procedure. 12 or no. This incision has also been termed the first incision, because it is the initial incision for the reflection of a periodontal flap; it has also been called the reverse bevel incision, because its bevel is in reverse direction from that of the gingivectomy incision. A crescent-shaped incision is sometimes used during the crown lengthening procedure. The interdental incision is then made to severe the inter-dental fiber attachment. Ramfjord SP, Nissle RR. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective. The coronally directed incision is designated as external bevel incision whereas the apically directed incisions are the internal bevel and sulcular incision. There is a loud S1 The murmur is a mid-diastolic rumbling heard best at . The main causes for the bleeding include intrinsic trauma to the operated site, even after repeated instructions patients tend to play with the area of surgery with their tongue and dislodge the blood clot, tongue may also cause suction of blood by creating small negative pressures that cause secondary bleeding, presence of foreign bodies, infection, salivary enzymes may lyse the blood clot before it gets organized and slippage of suture. Contents available in the book . It is most commonly caused due to infection and sloughing of blood vessels. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. The surgical approaches that split the papilla cause shrinkage and decrease in the height of the interdental papilla leading to the exposure of interproximal embrasures. With the help of Ochsenbein chisels (no. The first documented report of papilla preservation procedure was by Kromer 24 in 1956, which was designed to retain osseous implants. See video of the surgery at: Modified flap operation. References are available in the hard-copy of the website. Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. The original intent of the surgery was to access the root surface for scaling and root planing. Sutures are removed after one week and the area is irrigated with normal saline. The primary incision is placed at the outer margin of the gingivectomy incision starting at the disto-palatal line angle of the last molar and continued forward. No incision is made through the interdental papillae. Conventional flaps include the. Assign a 'primary' menu craigslist hattiesburg ms community ; cottonwood financial administrative services, llc Contents available in the book .. Contents available in the book .. a. The granulomatous tissue is then removed and the deposits on the root surfaces are removed by scaling. Possibility of exposure of furcations and roots, which complicates postoperative supragingival plaque control. 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated. Undisplaced femoral neck fractures in children have a high risk of secondary displacement. Contents available in the book .. (1995, 1999) 29, 30 described . After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades . This incision, together will the para-marginal internal bevel incision, forms a V-shaped wedge ending at or near the crest of bone, containing most of the inflamed and . 12 or no. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. This incision is made from the crest of the gingival margin till the crest of alveolar bone. The design of the flap is dictated by the surgical judgment of the operator, and it may depend on the objectives of the procedure. Refer to oral surgeon for biopsy ***** B. 5. Unsuitable for treatment of deep periodontal pockets. Triangular Contents available in the book . It can be used in combination with other procedures such as osseous resection, regenerative procedures, hemisection procedure and procedures involving wedge excision. Apically displaced flap, and The following steps outline the modified Widman flap technique. The periodontal flap surgeries have been practiced for more than one hundred years now, since their introduction in the early 1900s. Itisnecessary toemphasise thefollowing points: I)Reaming ofthemedullary cavity wasnever employed. Contents available in the book .. 2006 Aug;77(8):1452-7. The root surfaces are checked and then scaled and planed, if needed (. (2010) Factor V Leiden Mutation and Thrombotic Occlusion of Microsurgical Anastomosis After Free TRAM Flap. Periodontal pockets in severe periodontal disease. This drawback of conventional flap techniques led to the development of this flap technique which intended to spare the papilla instead of splitting it. 2. Undisplaced (replaced) flap This type of periodontal flap Apically positions pocket wall and preserves keratinized gingiva by apically positioning Apically displaced (positioned) flap This type of incision is used for what type of flap? The triangular wedge of the tissue, hence formed is removed. With our innovative curriculum and cutting-edge training methods, we are committed to delivering the highest quality of dental education and expertise to our students. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. The following outline of this technique: The information presented in this website has been collected from various leading journals, books and websites. The aim of this study was to test the null hypothesis of no difference in the implant failure rates, postoperative infection, and marginal bone loss for patients being rehabilitated by dental implants being inserted by a flapless surgical procedure versus the open flap technique, against the alternative hypothesis of a difference. The main advantages of this procedure are maximum conservation of the keratinized tissue, maximum closure of the flaps and greater access to the underlying bony topography and the distal furcation. The objectives for the other two flap proceduresthe undisplaced flap and the apically displaced flapinclude root surface access and the reduction or elimination of the pocket depth. The scalloping of the incision may not be accentuated as the flap has to be apically displaced and is not adapted interdentally. Deep intrabony defects. Tooth with extremely unfavorable clinical crown/root ratio. Apically-displaced Flap Full-thickness or partial thickness flap may be elevated depending on the objectives of the surgery. The narrow width of attached gingiva which may further reduce post-operatively. What are the steps involved in the Apically Displaced flap technique? These incisions are made in a horizontal direction and may be coronally or apically directed. The flap procedures on the palatal aspect require a different approach as compared to other areas because the palatal tissue is composed of a dense collagenous fiber network and there is no movable mucosa on the palatal aspect. 74. Position of the knife to perform the internal bevel incision. The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. Contents available in the book . In another technique, vertical incisions and a horizontal incision are placed. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. For flap placement after surgery, flaps are classified as either (1) nondisplaced flaps, when the flap is returned and sutured in its original position, or (2) displaced flaps, which are placed apically, coronally, or laterally to their original position. 2. Table 1: showing thickness of gingiva in maxillary tooth region . The granulation tissue and the pocket lining may be then separated from the inner surface of the reflected flap with the help of surgical scissors and a scalpel. As the flap is to be placed in an apical position, vertical incisions are made extending beyond the mucogingival junction. 16: 199-203 . The partial-thickness flap is indicated when the flap is to be positioned apically or when the operator does not want to expose bone. It produces a sharp, thin flap margin for adaptation to the bone-tooth junction. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective . It is most commonly caused due to infection and sloughing of blood vessels. In 1965, Morris4 revived a technique described early during the twentieth century in the periodontal literature; he called it the unrepositioned mucoperiosteal flap. Essentially, the same procedure was presented in 1974 by Ramfjord and Nissle,6 who called it the modified Widman flap (Figure 59-3). Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. Areas with sufficient band of attached gingiva. Areas which do not have an esthetic concern. Endodontic Topics. We describe the technique of diagnosis and treatment of a large displaced lateral meniscus flap tear, presenting as a meniscus comma sign. Periodontal pockets in areas where esthetics is critical. The present systematic review analysed the clinical outcomes of resective surgery versus access flap procedures in subjects with periodontitis stages II-III (previously termed moderate to advanced periodontitis), in order to support the development of evidence-based guidelines for periodontal therapy. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. The following statements can be made regarding periodontal regeneration procedures. b. Papilla preservation flap. Figure 2:The graph represents the distribution of various The incision is made at the level of the pocket to discard the tissue coronal to the pocket if there is sufficient remaining attached gingiva. The undisplaced (unrepositioned) flap improves accessibility for instrumentation, but it also removes the pocket wall, thereby reducing or eliminating the pocket. 2. The internal bevel incision starts from a designated area on the gingiva, and it is then directed to an area at or near the crest of the bone (. In areas with a narrow width of attached gingiva. There is no need to determine where the bottom of the pocket is in relation to the incision for the apically displaced flap as one would for the undisplaced flap. The reduction of bacterial load and inflammation minimizes further loss of tooth-supporting structures and thus aid in the better prognosis of teeth, provided, the patient stays on a strict maintenance schedule. Pronounced gingival overgrowth, which is handled more efficiently by means of gingivectomy / gingivoplasty. The palatal flap offers a technically simple and predictable option for intraoral reconstruction. The area is then re-inspected for any remaining granulation tissue, tissue tags and deposits on root surfaces. The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. 6. A study made before and 18 years after the use of apically displaced flaps failed to show a permanent relocation of the mucogingival junction.1. The periodontal dressing is not required if the flap has been adapted adequately to cover the interdental area. 15 scalpel blade is used to make a triangular incision distal to the molar on retromolar pad area or the maxillary tuberosity. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. Short anatomic crowns in the anterior region. a. Full-thickness flap. a. Non-displaced flap. The internal bevel incision may be a marginal incision (from the top of gingival margin) or para-marginal incision (at a distance from the gingival margin). Contents available in the book .. 1. Contents available in the book . In addition, the interdental incision is performed after the flap is elevated to remove the interdental tissue. Internal bevel and is 0.5-1.0mm from gingival margin Modified Widman Flap Step 1:The pockets are measured with the periodontal probe, and a bleeding point is produced on the outer surface of the gingiva to mark the pocket bottom. Suturing is then done using a continuous sling suture. Depending on the purpose, it can be a full . Modified Widman flap and apically repositioned flap. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. After this, partial elevation of the flap is done with the help of a small periosteal elevator. Contents available in the book .. 2. Its final position is not determined by the placement of the first incision. If a full-thickness flap has been elevated, the sutures are placed along the mesial and the distal vertical incision lines to. During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot. A progressive brous enlargement of the gingiva is a facet of idiopathic brous hyperplasia of the gingiva (Carranza and Hogan,; Gorlinetal., ).Itisdescribedvariouslyas bromatosisgingivae,gingivostomatitis,hereditarygingival bromatosis, idiopathic bromatosis, familial elephantiasis, and di use broma . Areas where greater probing depth reduction is required. Enter the email address you signed up with and we'll email you a reset link. The internal bevel incisions are typically used in periodontal flap surgeries. Contents available in the book .. 34. Periodontal therapy, flap, periodontal flap, full thickness flap, partial thickness flap, nondisplaced flap, displaced flap, conventional flaps, papilla preservation . This approach was described by Staffileno (1969) 23. . Every effort is made to adapt the facial and lingual interproximal tissue adjacent to each other in such a way that no interproximal bone remains exposed at the time of suturing. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. In case of generalized chronic periodontitis with localized gingival overgrow th,undisplaced flap with internal bevel incision has given better results esthetically and structurally .Thus with th is approach there is improvement in periodontal health along with good esthetics. The continuous sling suture has an advantage that it uses tooth as an anchor and thus, facilitates to hold the flap edges at the root-bone junction. The beak-shaped no. The choice of which procedure to use depends on two important anatomic landmarks: the pocket depth and the location of the mucogingival junction. Contents available in the book .. Following shapes of the distal wedge have been proposed which are, 1. The patient is then recalled for suture removal after one week. In this technique no. The distance of the primary incision from the gingival margin depends on the thickness of the gingiva. Undisplaced flap and apically repositioned flap. These vertical incisions are now joined with a horizontal incision as shown in the following figure. Flaps are used for pocket therapy to accomplish the following: 1. When bone is stripped of its periosteum, a loss of marginal bone occurs, and this loss is prevented when the periosteum is left on the bone. The blood clot provides a framework for the proliferation and migration of cells from surrounding tissues including gingiva, periodontal ligament (PDL), cementum, and alveolar bone 38. This increase in the width of the attached gingiva is based on the apical shift of the mucogingival junction, which may include the apical displacement of the muscle attachments. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Depending on how the interdental papilla is managed, flaps can either split the papilla (conventional flap) or preserve it (papilla preservation flap). The modified Widman flap facilitates instrumentation for root therapy. Maintaining primary closure after guided bone regeneration procedures: Introduction of a new flap design and preliminary results. Contents available in the book . Ramfjord and Nissle6 performed an extensive longitudinal study that compared the Widman procedure (as modified by them) with the curettage technique and the pocket elimination methods, which include bone contouring when needed. This incision is placed through the gingival sulcus. 2. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. This website is a small attempt to create an easy approach to understand periodontology for the students who are facing difficulties during the graduation and the post-graduation courses in our field. 12 or no. This is a commonly used incision during periodontal flap surgeries. If detected, they are removed. 1. Contents available in the book .. Preservation of good blood supply to the flap is another important consideration. The bone remains covered by a layer of connective tissue that includes the periosteum. The area is then irrigated with an antimicrobial solution. The necessary degree of access to the underlying bone and root surfaces and the final position of the flap must be considered when designing the flap. They are also useful for treating moderate to deep periodontal pockets in the posterior regions. The incision is carried around the entire tooth. Otherwise, the periodontal dressing may be placed. It allows the vertical incision to be sutured without stretching the flap over the cervical convexity of the tooth. preservation flap ) papila interdental tidak terpotong karena tercakup ke salah satu flep (gambar 2C). 1972 Mar;43(3):141-4. THE UNDISPLACED FLAP TECHNIQUE Step 1: Measure pockets by periodontal probe,and a bleeding point is produced on the outer surface of the gingiva by pocket marker. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. Give local anaesthetic for 2 weeks and recall C. Recall for follow up after 6 weeks D. 13- Which is the technique that will anesthetize both hard and soft tissues of the lower posterior teeth region in one injection A. Gow gates***** B. 1. It is better to graft an infrabony defect than not grafting. A. Periodontal flaps can be classified on the basis of the following: For bone exposure after reflection, the flaps are classified as either full-thickness (mucoperiosteal) or partial-thickness (mucosal) flaps (Figure 57-1). Long-term outcome of undisplaced fatigue fractures of the femoral neck in young male adults; In 1973, App 25 reported a similar technique and termed it as Intact Papilla Flap which retained the interdental gingiva in the buccal flap. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. The para-marginal internal bevel incision accomplishes three important objectives. In case of periodontitis with active pockets 5-6 mm deep or greater, that do not respond satisfactorily to the initial therapy. The deposits on the root surfaces are removed and root planing is done. This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. The bleeding is frequently associated with pain. It is an access flap for the debridement of the root surfaces. The area is anesthetized and bone sounding is done to evaluate the osseous topography, pocket depth, and thickness of the gingiva. Methods Twelve patients younger than 18 years with scaphoid nonunion, who underwent a VTMPF procedure without bone grafting , were included for this prospective cohort . Most commonly done suturing is the interrupted suturing. The apically displaced flap provides accessibility and eliminates the pocket, but it does the latter by apically positioning the soft-tissue wall of the pocket.2 Therefore, it preserves or increases the width of the attached gingiva by transforming the previously unattached keratinized pocket wall into attached tissue. Flap design for a sulcular incision flap. Residual periodontal fibers attached to the tooth surface should not be disturbed. The first, second and third incisions are placed in the same way as in case of modified Widman flap and the wedge of the infected tissue is removed. Locations of the internal bevel incisions for the different types of flaps. 1- initial internal bevel incision 2- crevicular incisions 3- initial elevation of the flap 4- vertical incisions extending beyond the mucogingival junction 5- SRP performed 6- flap is apically positioned 7- place periodontal dressing to ensure the flap remains apically displaced For the correction of bone morphology (osteoplasty, osseous resection). In the present discussion, we shall study in detail, the current concepts and advances in various periodontal flap surgeries. Alveolar crest reduction following full and partial thickness flaps. By doing this, the periosteum is cut and it becomes easy to remove the secondary flap from the bone. Tooth with marked mobility and severe attachment loss. 61: Periodontal Regeneration and Reconstructive Surgery, 63: Periodontal Plastic and Esthetic Surgery, 55: General Principles of Periodontal Surgery, 30: Significance of Clinical and Biologic Information. Chlorhexidine rinse 0.2% bid . Care should be taken to insert the blade in such a way that the papilla is left with a thickness similar to that of the remaining facial flap. Contents available in the book .. This is especially important because, on the palatal aspect, osseous deformities such as heavy bone ledges and exostoses are commonly seen. The granulation tissue is highly vascularized, so it bleeds profusely. In non-esthetic areas with moderate to deep pockets and for crown lengthening, this incision is indicated. Possibility of exposure of furcations and roots, which complicates postoperative supragingival plaque control. An interdental (third) incision along the horizontal lines seen in the interdental spaces will sever these connections. The initial or internal bevel incision is made (. Contents available in the book .. Contents available in the book .. Therefore, the two anatomic landmarksthe pocket depth and the location of the mucogingival junctionmust be considered to evaluate the amount of attached gingiva that will remain after the surgery has been completed. 1. Click this link to watch video of the surgery: Areas where greater probing depth reduction is required. Apically displaced flap. Inferior alveolar nerve block C. PSA 14- A patient comes with . At last periodontal dressing may be applied to cover the operated area. The thicker the tissue is, the more apical the ending point of the incision (see Figure 59-4). The distance of the incision from the gingival margin (thickness of the incision) varies according to the pocket depth, the thickness of the gingiva, width of the attached gingiva, shape and contour of gingival margins and whether or not the operative area is in the esthetic zone. Step 1:The initial incision is an internal bevel incision to the alveolar crest starting 0.5mm to 1mm away from the gingival margin (Figure 59-3, C). Contents available in the book .. Contents available in the book .. Coronally displaced flap Connective tissue autograft Free gingival graft Laterally positioned flap Apically displaced flap 5. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. . With some variants, the apically displaced flap technique can be used for (1) pocket eradication and/or (2) widening the zone of attached gingiva. The first incision or the internal bevel incision is then made from the bleeding points directed at an apical level to the alveolar crest. The main advantages of this procedure are the preservation of maximum healthy tissue and minimum post-operative discomfort to the patient. A vertical incision may be given unilaterally (at one end of the flap) or bilaterally (on both ends of the flap). Our main aim of doing so is to get complete access to the root surfaces of the teeth and bone defects around the teeth. The basic clinical steps followed during this flap procedure are as follows. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. With this access, the surgeon is able to make the third incision, which is also known as the interdental incision, to separate the collar of gingiva that is left around the tooth. The following steps outline the undisplaced flap technique. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. Need to visually examine the area, to make a definite diagnosis. 2. Ramfjord and Nissle 8 in 1974, modified the original Widman flap procedure . Following is the description of these flaps. Periodontal flap surgery with conventional incision commonly results in gingival recession and loss of interdental papillae after treatment. A crevicular incision is made from the bottom of the pocket to the bone in such a way that it circumscribes the triangular wedge of tissue that contains the pocket lining. Contents available in the book .. In this technique, two incisions are made with the help of no. This preview shows page 166 - 168 out of 197 pages.. View full document. 2. Henry H. Takei, Fermin A. Carranza and Jonathan H. Do. In this flap, only epithelium and the underlying connective tissue are reflected, leaving the periosteum intact. To perform this technique without creating a mucogingival problem, the clinician should determine that enough attached gingiva will remain after removal of the pocket wall. Rough handling of the tissue and long duration of the surgery commonly result in post-operative swelling. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. In addition, thinning of the flap should be performed with the initial incision, because it is easier to accomplish at this time than it is later with a loose, reflected flap that is difficult to manage. Another important objective of periodontal flap surgery is to regenerate the lost periodontal apparatus. Vertical incisions increase flap mobility, thus facilitating better access to the operative area.
