Laparoscopic technique for secondary vaginoplasty in male to female transsexuals using a modified . The internal bevel incision in an undisplaced flap procedure is started at the same point where an external bevel incision is started in agingivectomyprocedure. The original intent of the surgery was to access the root surface for scaling and root planing. The key point to be remembered here is, more the thickness of the gingiva more scalloped is the incision. For the management of the papilla, flaps can be conventional or papilla preservation flaps. The triangular wedge of the tissue, hence formed is removed. Sutures are placed to secure the flaps in their position. 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. 5. ious techniques such as gingivectomy, undisplaced flap with/without bone surgery, apical resected flap with/without bone resection, and forced eruption with/without fiberotomy have been proposed for crown lengthening procedures.2-4 Selecting the technique depends on various factors like esthetics, crown-to-root ratio, root morphology, furcation According to flap reflection or tissue content: C. According to flap placement after surgery: Diagram showing full-thickness and partial-thickness flap. These . As described in, Image showing primay and secondary incisions used in ledge and wedge technique. In case of periodontitis with active pockets 5-6 mm deep or greater, that do not respond satisfactorily to the initial therapy. Because the pocket wall is not displaced apically, the initial incision should eliminate the pocket wall.

Suturing techniques for periodontal plastic surgery Contents available in the book .. The design of the flap is dictated by the surgical judgment of the operator, and it may depend on the objectives of the procedure. Contents available in the book .. Vertical incisions increase flap mobility, thus facilitating better access to the operative area. (1985) 26 modified this procedure to preserve anterior esthetics after flap surgery. This technique offers the possibility of establishing an intimate postoperative adaptation of healthy collagenous connective tissue to tooth surfaces,2,3,5,6 and it provides access for adequate instrumentation of the root surfaces and immediate closure of the area. 1. Contents available in the book .. 12D blade is usually used for this incision. In areas with shallow periodontal pocket depth. In Figure 2, the frequency of the types of flap surgical techniques followed were analyzed. The meniscus comma sign has been described for displaced flap tears of the meniscus. Trochleoplasty with a flexible osteochondral flap; The role of the width of the forefoot in the development of Morton's neuroma; February. Pronounced gingival overgrowth, which is handled more efficiently by means of gingivectomy / gingivoplasty. The starting point on the gingiva is determined by whether the flap is apically displaced or not displaced (Figure 57-7). 57: The Periodontal Flap | Pocket Dentistry The efficacy of pocket elimination/reduction compared to access 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). 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. This is mainly because of the reason that all the lateral blood supply to . The incision is made. Coronally displaced flap. 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 incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Step 2:The gingiva is reflected with a periosteal elevator (Figure 59-3, D). Semiconductor chip assemblies, methods of making same and components After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective. Step 2:The initial or internal bevel incision is made (Figure 59-4) after scalloping the bleeding marks on the gingiva (Figure 59-5). This incision is made from the crest of the gingival margin till the crest of alveolar bone. According to flap reflection or tissue content: . The incision is carried around the entire tooth. Periodontal flaps involve the use of horizontal (mesialdistal) and vertical (occlusalapical) incisions. It is indicated where complete access to the bone is required, for example, in the case of osseous resective surgeries. 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 internal bevel incision is basic to most periodontal flap procedures. Contents available in the book .. Clin Appl Thromb Hemost. The internal bevel incisions are typically used in periodontal flap surgeries. It reduces mouth opening, is commonly associated with pain and causes difficulty in mastication. It produces a sharp, thin flap margin for adaptation to the bone-tooth junction. This is a commonly used incision during periodontal flap surgeries. The following statements can be made regarding periodontal regeneration procedures. The coronally directed incision is designated as external bevel incision whereas the apically directed incisions are the internal bevel and sulcular incision. Periodontal pockets in areas where esthetics is critical. This is also known as Ledge-and-wedge technique. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . Journal of periodontology. The undisplaced (unrepositioned) flap improves accessibility for instrumentation, but it also removes the pocket wall, thereby reducing or eliminating the pocket. Vertical relaxing incisions are usually not needed. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . 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 In case where the soft tissue is quite thick, this incision. The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. These are indicated in cases where interdental spaces are too narrow and when the flap needs to be displaced. Osce Handbook [34m7z5jr9e46] The book is usually delivered within one week anywhere in India and within three weeks anywhere throughout the world. 7. During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot. Step 2: The initial, or internal bevel, incision is made. This is a modification of the partial thickness palatal flap procedure in which gingivectomy is done prior to the placement of primary and the secondary incision. At last periodontal dressing may be applied to cover the operated area. All the pocket epithelium and granulation tissue from the inner surfaces of the flaps is then eliminated using sharp curved scissors or Castroviejo scissors. Eliminate or reduce pocket depth via resection of the pocket wall, 3. Areas where post-operative maintenance can be most effectively done by doing this procedure.

The classic treatment till today in developing countries is removal of excess gingival growth by scalpel but one should remember about the periodontal treatment which should be done before commencing the surgical part of . HGF is characterized as a benign, slowly progressive, nonhemorrhagic, fibrous enlargement of keratinized gingiva.It can cover teeth in various degrees, and can lead to aesthetic disfigurement. The bleeding may range from a minor leakage or oozing, to extensive or frank bleeding at the surgical site. Flap for regenerative procedures. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. The apically displaced flap is . 30 Q . It is the incision from which the flap is reflected to expose the underlying bone and root. Unsuitable for treatment of deep periodontal pockets. It is most commonly caused due to infection and sloughing of blood vessels. 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. In 1973, App 25 reported a similar technique and termed it as Intact Papilla Flap which retained the interdental gingiva in the buccal flap. Contents available in the book .. The blade should be kept on the vertical height of the alveolus so that palatal artery is not injured. Contents available in the book . The primary objective of the flap surgeries is to gain access to the root surfaces and bone defects so that the deposits on the root surfaces can be eliminated and the granulation tissue can be removed. Fibrous enlargement is most common in areas of maxillary and mandibular . Apically displaced flap, and After the administration of local anesthesia, bone sounding is performed to identify the exact thickness of the gingiva. As soon the granulation tissue is removed, the clear bone margins and root surfaces are visible.

The area is re-inspected for any remaining granulation tissue, tissue tags or deposits on the root surfaces. This flap procedure may be regarded as internal bevel gingivectomy because the first incision or the internal bevel incision given during this procedure is placed at the level of pocket depth (Figure 62.1), thus including all the soft tissue containing and supporting periodontal pocket. Then sharp periodontal curettes are used to remove the granulomatous tissue and tissue tags. Swelling is another common complication after flap surgery. Access flap for guided tissue regeneration. The incision is made not only around the facial and lingual radicular area but also interdentally, where it connects the facial and lingual segments to free the gingiva completely around the tooth (Figure 57-9; see Figure 57-5). An intact papilla should be either excluded or included in the flap. The following steps outline the modified Widman flap technique. This internal bevel incision is placed at a distance from the gingival margin, directed towards the alveolar crest. periodontal flaps docx - Dr. Ruaa - Muhadharaty As already discussed in, History of surgical periodontal pocket therapy and osseous resective surgeries the original Widman flap was presented to the Scandinavian Dental Association in 1916 by Leonard Widman which was later published in 1918. Conventional flaps include the. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. The vertical incision must extend beyond the mucogingival line, reaching the alveolar mucosa, to allow for the release of the flap to be displaced. Fugazzotto PA. The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. It does not attempt to reduce the pocket depth, but it does eliminate the pocket lining.

The Undisplaced Flap - Periodontal Disease - Click to Cure Cancer The periodontal dressing is not required if the flap has been adapted adequately to cover the interdental area. Although some details may be modified during the actual performance of the procedure, detailed planning allows for a better clinical result. These vertical incisions are now joined with a horizontal incision as shown in the following figure. Full-thickness or partial thickness flap may be elevated depending on the objectives of the surgery. The triangular wedge of the tissue, hence formed is removed. 12 or no. 3. In this technique, two incisions are made with the help of no. JaypeeDigital | Periodontal Flap It is also known as a partial-thickness flap. 7. 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. Severe hypersensitivity. Tooth movement and implant esthetics. Contents available in the book .. After this, partial elevation of the flap is done with the help of a small periosteal elevator. The crevicular incision is then placed from the bottom of the pocket till the alveolar crest. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. The secondary flap removed, can be used as an autogenous connective tissue graft. 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 first documented report of papilla preservation procedure was by Kromer 24 in 1956, which was designed to retain osseous implants. The papilla preservation flap incorporates the entire papilla in one of the flaps by means of crevicular interdental incisions to sever the connective tissue attachment as well as a horizontal incision at the base of the papilla to leave it connected to one of the flaps. The vertical incision should be made in such a way that interdental papilla is completely preserved. Crown lengthening surgery: A periodontal makeup for anterior esthetic Osseous surgical procedures with very deep osseous defects and irregular bone loss, facially and lingually/ palatally. The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). Depending on how the interdental papilla is managed, flaps can either split the papilla (conventional flap) or preserve it (papilla preservation flap). 1. The flap is then elevated with the help of a small periosteal elevator. Pockets around the teeth in which a complete removal of root irritants is not clinically possible without gaining complete access to the root surfaces. Periodontal flap surgeries: current concepts - periobasics.com Contents available in the book . The internal beveled incision for the modified Widman flap closely follows the scalloped outline of the dentition to minimize the loss of the attached keratinized gingiva. The incisions given are the same as in case of modified Widman flap procedure. The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. Root planing is done followed by osseous surgery if needed. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort.

The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. 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. This approach was described by Staffileno (1969) 23. 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. For the treatment of periodontal pockets with minimal osseous defects, a procedure without or minimal osseous resection is done, whereas, in case of moderate osseous defects and crown lengthening procedures, osseous resection is done with the flap procedure. If the surgeon contemplates osseous surgery, the first incision should be placed in such a way to compensate for the removal of the bone tissue so that the flap can be placed at the toothbone junction. Periodontal flap surgery with conventional incision commonly results in gingival recession and loss of interdental papillae after treatment. Local anesthesia is administered to achieve profound anes-thesia in the area to be operated. 4. After this, the second incision or the sulcular incision is made from the bottom of the pocket to the crest of the alveolar bone. Undisplaced femoral neck fractures in children have a high risk of secondary displacement. 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 . Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. Hereditary gingival fibromatosis - Wikipedia Step 2: The initial, internal bevel incision is made after the scalloping of the bleeding marks on the gingiva. (The use of this technique in palatal areas is considered in the discussion that follows this list. Preservation of good blood supply to the flap is another important consideration. (PDF) Association Between Periodontal Flap Design And - ResearchGate This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. The distance of the primary incision from the gingival margin depends on the thickness of the gingiva. In addition, the interdental incision is performed after the flap is elevated to remove the interdental tissue. The area is then irrigated with an antimicrobial solution. Contents available in the book .. Which of the following mucogingival surgical techniques is indicated in areas of narrow gingival recession adjacent to a wide band of attached gingiva that can be used as a donor site? free gingival autograft double papilla flap modified Widman flap laterally displaced (positioned . 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated. Pocket depth was initially similar for all methods, but it was maintained at shallower levels with the Widman flap; the attachment level remained higher with the Widman flap.
