Contents available in the book .. Its final position is not determined by the placement of the first incision. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. Flap reflection till alveolar mucosa to mobilize the flap causes more post-operative pain and discomfort. News & Perspective Drugs & Diseases CME & Education Vertical relaxing incisions are usually not needed. 1 and 2), the secondary inner flap is removed. Tooth with marked mobility and severe attachment loss. There are two types of incisions that can be used to include interdental papillae in the facial flap: One technique includes semilunar incisions which are. Minor osseous recontouring may be done and the flap is then adapted into the interdental areas. Undisplaced flap and apically repositioned 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. These incisions are made in a horizontal direction and may be coronally or apically directed. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. 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. ), Only gold members can continue reading. Contents available in the book .. Step 5:Tissue tags and granulation tissue are removed with a curette. After this, the second or the sulcular incision is made from the bottom of the pocket till the crest of the alveolar bone. The flaps are then apically positioned to just cover the alveolar crest. For this reason, the internal bevel incision should be made as close to the tooth as possible (i.e., 0.5mm to 1.0mm) (see Figure 59-1). Conventional surgical approaches include the coronal flap, direct cutaneous incision, and endoscopic techniques. References are available in the hard-copy of the website. 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. To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. Conflicting data surround the advisability of uncovering the bone when this is not actually needed. After the patient has been thoroughly evaluated and pre-pared with non-surgical periodontal therapy, quadrant or area to be operated is selected. The periodontal pockets on the distal aspects of last molars, both in maxillary and the mandibular arches present a unique situation for which specific surgical designs have been advocated. In areas with a narrow width of attached gingiva. In a full-thickness flap, all of the soft tissue, including the periosteum, is reflected to expose the underlying bone. Disain flep ini memberikan estetis pasca bedah yang lebih baik, dan memberikan perlindungan yang lebih baik terhadap tulang interdental, hal mana penting sekali dalam tehnik bedah yang mengharapkan terjadinya regenerasi jaringan periodontium. The periodontal dressing is not required if the flap has been adapted adequately to cover the interdental area. The blade is introduced into the sulcus or pocket and is inserted as far as possible into the interdental space around the tooth, keeping it close to the crown. More is the thickness of the gingiva, farther is the incision placed to include more tissue which needs to be removed. Modified Widman flap and apically repositioned flap. Contents available in the book . Contents available in the book .. The crevicular incision, which is also called the second incision, is made from the base of the pocket to the crest of the bone (Figure 57-8). Vertical incisions increase flap mobility, thus facilitating better access to the operative area. Periodontal pockets in severe periodontal disease. A crescent-shaped incision is sometimes used during the crown lengthening procedure. Contents available in the book .. 2. The area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. In this technique no. 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. To evaluate clinical and radiological outcomes after surgical treatment of scaphoid nonunion in adolescents with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF). A. Different Flap techniques for treatment of gingival recession (Lateral-coronal-double papilla-semilunar-tunnel-apical). After debridement, flaps are closely adapted around the teeth in close approximation, allowing healing by primary intention. Within the first few days, monocytes and macrophages start populating the area 37. Journal of periodontology. For the management of the papilla, flaps can be conventional or papilla preservation flaps. 2)Wenow employ aK#{252}ntscher-type nailslightly bent forward inits upper part, allowing easier removal when indicated. 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 (. The vertical incisions are made from the center of palatal/lingual surfaces of teeth extending palatally/lingually. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. Step 2:The gingiva is reflected with a periosteal elevator (Figure 59-3, D). 2. May cause hypersensitivity. The deposits on the root surfaces are removed and root planing is done. Frenectomy-frenal relocation-vestibuloplasty. 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. Contents available in the book . These . Contents available in the book . One incision is now placed perpendicular to these parallel incisions at their distal end. The following steps outline the undisplaced flap technique: Step 1: The pockets are measured with the periodontal probe. Increase accessibility to root deposits for scaling and root planing, 2. Burkhardt R, Lang NP. In this flap procedure, no ostectomy is performed; however, minor osetoplasty may be done to modify the undesired bony architecture. The blade is pushed into the sulcus till resistance is felt from the crestal bone crest. 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. This wedge of tissue contains most of the inflamed and granulomatous areas that constitute the lateral wall of the pocket as well as the junctional epithelium and the connective tissue fibers that still persist between the bottom of the pocket and the crest of the bone. Contents available in the book .. The modified Widman flap. 6. The researchers reported similar results for each of the three methods tested. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. Ramfjord and Nissle 8 in 1974, modified the original Widman flap procedure . This procedure cannot be done on the palatal aspect as it has attached gingiva which cannot be displaced apically. Following is the description of marginal and para-marginal internal bevel incisions. 15c or No. This type of flap is also called the split-thickness flap. Contents available in the book .. Suturing techniques. The pockets are then measured and bleeding points are produced with the help of a periodontal probe on the outer surface of the gingiva, indicating the bottom of the pocket. 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. 4. Contents available in the book .. These landmarks establish the presence and width of the attached gingiva, which is the basis for the decision. This incision is made 1mm to 2mm from the teeth. The area to be operated is irrigated with an antimicrobial solution and isolated. Contents available in the book .. This incision is indicated in the following situations. Swelling hinders routine working life of patient usually during the first 3 days after surgery 41. Contents available in the book .. Access flap for guided tissue regeneration. It was described by Kirkland in 1931 31. 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. See Page 1 Contents available in the book . Contents available in the book .. The square . Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. If a full-thickness flap has been elevated, the sutures are placed along the mesial and the distal vertical incision lines to. (adsbygoogle = window.adsbygoogle || []).push({}); The external bevel incision is typically used in gingivectomy procedures. Ahmad Syaify, Sp.Perio (K) Spesialis Konsultan Bedah Perio & Estetik. The gingival margin is removed, and the flap is reflected to gain access for root therapy. The following steps outline the undisplaced flap technique. The crevicular incision is then placed from the bottom of the pocket till the alveolar crest. The secondary. 6. Contents available in the book .. Kirkland flap method was the most commonly followed (60.47%), then it was modified widman flap (29.65%), undisplaced flap (6.39%) and distal wedge which was the lowest (3.48%). The periosteum left on the bone may also be used for suturing the flap when it is displaced apically. The periodontal pockets on the distal aspects of last molars, both in maxillary and the mandibular arches present a unique situation for which specific surgical designs have been advocated. 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). Root planing is done followed by osseous surgery if needed. Step 4:After the flap is reflected, a third incision is made in the interdental spaces coronal to the bone with a curette or an interproximal knife, and the gingival collar is removed (Figure 59-3, E and F). Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. 3. 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 full-thickness flap is elevated with the help of a periosteal elevator whereas partial-thickness flap is elevated using sharp dissection with a Bard-Parker knife. Fundamental principles in periodontal plastic surgery and mucosal augmentationa narrative review. These techniques are described in detail in Chapter 59. It is caused by trauma or spasm to the muscles of mastication. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. 3. 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). 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. 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. There have been a lot of modifications and improvisations in various periodontal surgical techniques during this period. 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. Methods Twelve patients younger than 18 years with scaphoid nonunion, who underwent a VTMPF procedure without bone grafting , were included for this prospective cohort . These vertical incisions are now joined with a horizontal incision as shown in the following figure. The undisplaced (unrepositioned) flap improves accessibility for instrumentation, but it also removes the pocket wall, thereby reducing or eliminating the pocket. 7. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. This suturing causes the apical positioning of the facial papilla, thus creating open gingival embrasures (black holes). 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. Periodontal pockets in severe periodontal disease. 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. Pockets around the teeth in which a complete removal of root irritants is not clinically possible without gaining complete access to the root surfaces. Laparoscopic technique for secondary vaginoplasty in male to female transsexuals using a modified . 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. 74. 1. The granulation tissue, as well as tissue tags, are then removed. The flap was repositioned and sutured and . The flaps are then replaced to their original position and sutured using interrupted or continuous sling sutures. Coronally displaced flap Connective tissue autograft Free gingival graft Laterally positioned flap Apically displaced flap 5. However, there are important variations in the way these incisions are performed for the different types of flaps (Figures 59-1 and 59-2). Modified Widman flap, It is caused by trauma or spasm to the muscles of mastication. Posterior spinal fusion for adolescent idiopathic scoliosis using a convex pedicle screw technique; . 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 the incision from which the flap is reflected to expose the underlying bone and root. Inferior alveolar nerve block C. PSA 14- A patient comes with . Table 1: showing thickness of gingiva in maxillary tooth region . 2011 Sep;25(1):4-15. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. For regenerative procedures, such as bone grafting and guided tissue regeneration. The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. After the flap is reflected, a third incision is made in the interdental spaces coronal to the bone with a curette or an interproximal knife, and the gingival collar is removed (, Tissue tags and granulation tissue are removed with a curette. Step 2: The mucogingival junction is assessed to determine the amount of keratinized tissue. Contents available in the book .. Hence, this suturing is mainly indicated in posterior areas where esthetics. This internal bevel incision is placed at a distance from the gingival margin, directed towards the alveolar crest. Step 2:The initial or internal bevel incision is made (Figure 59-4) after scalloping the bleeding marks on the gingiva (Figure 59-5). 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. b. Split-thickness flap. It is contraindicated in the areas where treatment for an osseous defect with the mucogingival problem is not required, in areas with thin periodontal tissue with probable osseous dehiscence or osseous fenestration and in areas where the alveolar bone is thin. 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 design may also be dictated by the aesthetic concerns of the area of surgery. UNDISPLACEDFLAP |Also known as internal bevel gingivectomy |Differs from the modified widman flap inthat pocket wall is removed with the initial incision TECHNIQUE |Pockets are measured with a pocket marker & a bleeding point is created THE INITIAL INTERNAL BEVEL INCISION IS CARRIED APICAL TO THE CREST OF BONE CONTD. This complete exposure of and access to the underlying bone is indicated when resective osseous surgery is contemplated. It is also known as a partial-thickness flap. Scalloping required for the different types of flaps (see, The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva.
