While doing laterally displaced flap for root coverage, the vertical incision is made at an acute angle to the horizontal incision, in the direction toward which the flap will move, placing the base of the pedicle at the recipient site. Contents available in the book .. Step 3: The second, or crevicular, incision is made from the bottom of the pocket to the bone to detach the connective tissue from the bone. The flap was repositioned and sutured [Figure 6]. Areas where greater probing depth reduction is required. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective . This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. 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. 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. A full-thickness flap is then elevated to expose 1-2 mm of the marginal bone. 7. Contents available in the book .. This incision, together with the initial reverse bevel incision, forms a V-shaped wedge that ends at or near the crest of bone. Semiconductor chip assemblies, methods of making same and components for sameSemiconductor chip assemblies, methods of making same and components for same .. .. . 2. 35. Contents available in the book .. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. The modified Widman flap facilitates instrumentation for root therapy. The presence of thin gingiva which does not allow placement of adequate initial internal bevel incision. According to flap reflection or tissue content: C. According to flap placement after surgery: Diagram showing full-thickness and partial-thickness flap. The flaps are then apically positioned to just cover the alveolar crest. The following steps outline the modified Widman flap technique. In case of periodontitis with active pockets 5-6 mm deep or greater, that do not respond satisfactorily to the initial therapy. - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). ), For the conventional flap procedure, the incisions for the facial and the lingual or palatal flap reach the tip of the interdental papilla or its vicinity, thereby splitting the papilla into a facial half and a lingual or palatal half (Figures 57-3 and. Sutures are placed to secure the flaps in their position. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. May cause hypersensitivity. Contents available in the book .. Contents available in the book .. In this technique no. Severe hypersensitivity. The area is then irrigated with an antimicrobial solution. As already stated, this technique is utilized when thicker gingiva is present. It is indicated where complete access to the bone is required, for example, in the case of osseous resective surgeries. The three different categories of flap techniques used in periodontal flap surgery are as follows: (1) the modified Widman flap; (2) the undisplaced flap; and (3) the apically displaced flap. As already stated, depending on the thickness of the gingiva, any of the following approaches can be used. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Contents available in the book .. Then sharp periodontal curettes are used to remove the granulomatous tissue and tissue tags. a. Full-thickness flap. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. When the flap is placed apically, coronally or laterally to its original position. If a full-thickness flap has been elevated, the sutures are placed along the mesial and the distal vertical incision lines to. The area is then irrigated with normal saline and flaps are adapted back in position. The factors that are associated with post-operative swelling include the type of the incision, its extension, tissue manipulation during the surgery and the duration of surgery. Step 6:Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. Access flap for guided tissue regeneration. Henry H. Takei, Fermin A. Carranza and Kitetsu Shin. The incision is usually carried to a point apical to the alveolar crest, depending on the thickness of the tissue. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. The choice of which procedure to use depends on two important anatomic landmarks: the pocket depth and the location of the mucogingival junction. Residual periodontal fibers attached to the tooth surface should not be disturbed. One technique includes semilunar incisions which are . After administrating local anesthesia, profound anesthesia is achieved in the area to be operated. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. Swelling hinders routine working life of patient usually during the first 3 days after surgery 41. A periodontal flap is a section of gingiva, mucosa, or both that is surgically separated from the underlying tissues to provide for the visibility of and access to the bone and root surface. 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. This is mainly because of the reason that all the lateral blood supply to. Two types of horizontal incisions have been recommended: the internal bevel incision,6 which starts at a distance from the gingival margin and which is aimed at the bone crest, and the crevicular incision, which starts at the bottom of the pocket and which is directed to the bone margin. Table 1: showing thickness of gingiva in maxillary tooth region . The periosteum left on the bone may also be used for suturing the flap when it is displaced apically. 2. Contents available in the book .. The incision is carried around the entire tooth. 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 Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window). These are indicated in cases where interdental spaces are too narrow and when the flap needs to be displaced. The cell surface components or adhesive molecules of bacteria that interact with a variety of host componentsand responsible for recognizing and binding to specific host cell receptors A. Cadherins B. Adhesins C. Cohesins D. Fimbriae Answer: B 2. Henry H. Takei, Fermin A. Carranza and Jonathan H. Do. Contents available in the book .. Swelling is another common complication after flap surgery. The Orban knife is usually used for this incision. Areas which do not have an esthetic concern. May cause esthetic problems due to root exposure. In this flap procedure, all the soft tissue, including the periosteum is reflected to expose the underlying bone. Sulcular incision is now made around the tooth to facilitate flap elevation. After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. This incision is always accompanied by a sulcular incision which results in the formation of a collar of gingival tissue which contains the periodontal pocket lining. Patients at high risk for caries. Periodontal therapy, flap, periodontal flap, full thickness flap, partial thickness flap, nondisplaced flap, displaced flap, conventional flaps, papilla preservation . 30 Q . 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. Which is the best method of brushing technique preferred for the patient with orthodontic appliance: ? The soft tissue is then retracted with tissue forceps and the scoring incision is given to separate the periosteum from the bone. It differs from the modified Widman llap in that the soft tissue pocket wall is removed with the initial incision; thus it may be considered an internal bevel glngivectomy. 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. In the present discussion, we shall study in detail, the current concepts and advances in various periodontal flap surgeries. in 1985 28 introduced a detailed description of the surgical approach reported earlier by Genon and named the technique as Papilla Preservation Flap. drg. More is the thickness of the gingiva, farther is the incision placed to include more tissue which needs to be removed. Contents available in the book . Alveolar crest reduction following full and partial thickness flaps. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. Contents available in the book .. Enter the email address you signed up with and we'll email you a reset link. Journal of clinical periodontology. The key point to be remembered here is, more the thickness of the gingiva more scalloped is the incision. The area to be operated is then isolated with the help of gauge. Maintaining primary closure after guided bone regeneration procedures: Introduction of a new flap design and preliminary results. The most abundant cells during the initial healing phase are the neutrophils. Apically displaced flap can be done with or without osseous resection. The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). The area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. Undisplaced femoral neck fractures in children have a high risk of secondary displacement. 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. Ahmad Syaify, Sp.Perio (K) Spesialis Konsultan Bedah Perio & Estetik. 1. b. Papilla preservation flap. Sutures are removed after one week and the area is irrigated with normal saline. News & Perspective Drugs & Diseases CME & Education This incision is indicated in the following situations. 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 most apical end of the internal bevel incision is exposed and visible. These, 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, The triangular wedge technique is used in cases where the adequate zone of attached gingiva is present and in cases of short or small tuberosity. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. The first step, Trismus is the inability to open the mouth. The deposits on the root surfaces are removed and root planing is done. Suturing is then performed to stabilize the flaps in their position. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. Locations of the internal bevel incisions for the different types of flaps. The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva. The modified Widman flap. Root planing is done followed by osseous surgery if needed. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. Increase accessibility to root deposits for scaling and root planing, 2. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. Periodontal pockets in severe periodontal disease. Flaps in which the interdental papilla is split beneath the contact of two approximating teeth, allowing the reflection of buccal and lingual flaps, are described as the conventional flaps. Contents available in the book .. Contents available in the book .. Palatal flaps cannot be displaced because of the absence of unattached gingiva. Position of the knife to perform the internal bevel incision. This is mainly because of the reason that all the lateral blood supply to . The researchers reported similar results for each of the three methods tested. Now, after the completion of the partial-thickness flap, the scalpel blade is directed from the base of this incision towards the bone to give a scoring incision. The incision is made . During crown lengthening, the shape of the para-marginal incision depends on the desired crown length. The information presented in this website has been collected from various leading journals, books and websites. After the gingivectomy incision, primary and the secondary incisions are placed in the same way as described in the partial-thickness flap procedure. These . The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. Contents available in the book .. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. The first step . A periodontal flap is a section of gingiva and/or mucosa surgically separated from the underlying tissue to provide visibility and access to the bone and root surfaces 1. Because the pocket wall is not displaced apically, the initial incision should eliminate the pocket wall. preservation flap ) papila interdental tidak terpotong karena tercakup ke salah satu flep (gambar 2C). See video of the surgery at: Modified flap operation. 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. 12D blade is usually used for this incision. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. The patient is recalled after one week for suture removal. A. The main advantages of this procedure are the preservation of maximum healthy tissue and minimum post-operative discomfort to the patient. Following are the steps followed during this procedure. 2. Trismus is the inability to open the mouth. that still persist between the bottom of the pocket and the crest of the bone. The modified Widman flap has been described for exposing the root surfaces for meticulous instrumentation and for the removal of the pocket lining.6 Again, it is not intended to eliminate or reduce pocket depth, except for the reduction that occurs during healing as a result of tissue shrinkage. 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.4 Although this is usually not clinically significant,7 the differences may be significant in some cases (Figure 57-2). Scaling, root planing and osseous recontouring (if required) are carried out. 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 . With this incision, the gingiva containing pocket lining is separated from the tooth surface. . The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. 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 following steps outline the undisplaced flap technique: Step 1: The pockets are measured with the periodontal probe. The incision is usually started at the disto-palatal line angle of the last molar and continued forward using a scalloped, inverse-beveled, partial-thickness incision to create a thin partial-thickness flap. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. Triangular Unsuitable for treatment of deep periodontal pockets. The three incisions necessary for flap surgery. 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. It must be noted that if there is no significant bleeding and flaps are closely adapted, periodontal dressing is not required. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. Incisions used in papilla preservation flap using primary, secondary and tertiary incisions. Practically, it is very difficult to put this incision because firstly, it is very difficult to keep the cutting edge of the blade at the gingival margin and secondly, the blade easily slips down into the pocket because of its close proximity to the tooth surface. The papillae are then carefully pushed back through the interdental embrasures to palatal or lingual aspect. Myocardial infarction / stroke within 6 months. Possibility of exposure of furcations and roots, which complicates postoperative supragingival plaque control.
