Background: Three-dimensional (3D) printing technology is increasingly commercially viable for pre-surgical planning, intraoperative templating, jig creation and customised implant manufacture. It protects the interdental papilla adjacent to the surgical site. (2010) Factor V Leiden Mutation and Thrombotic Occlusion of Microsurgical Anastomosis After Free TRAM Flap. Sixth day: (10 am-6pm); "Perio-restorative surgery" The bleeding may range from a minor leakage or oozing, to extensive or frank bleeding at the surgical site. It is also known as a partial-thickness flap. The vertical incision must extend beyond the mucogingival line, reaching the alveolar mucosa, to allow for the release of the flap to be displaced. The blade should be kept on the vertical height of the alveolus so that palatal artery is not injured. The buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. Then, it is decided that how much tissue has to be removed so that the appropriate thickness of the gingiva is achieved at the end of the procedure. Once the bone sounding has been done and the thickness of the gingiva has been established, the design of the flap is decided. 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. Contents available in the book .. The esthetic and functional demands of maxillofacial reconstruction have driven the evolution of an array of options. The no. After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades, In this technique, two incisions are made with the help of no. Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. Click this link to watch video of the surgery: Modified Widman Flap surgery. 1. Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap with or without resective osseous surgery, and orthodontic forced eruption with or without fibrotomy have been proposed for clinical crown lengthening. The most abundant cells during the initial healing phase are the neutrophils. Contents available in the book .. The beak-shaped no.

Platelets rich fibrin (PRF) preparation and application in the . 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. The vertical incision should be made in such a way that interdental papilla is completely preserved. During the initial phase of healing, inflammatory cells are attracted by platelet and complement derived mediators and aggregate around the blood clot. PDF BAB 13 BEDAH FLEP - Website Universitas Sumatera Utara Step 2: The initial, or internal bevel, incision is made. 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). 4. Placing periodontal depressing is optional. - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. In this flap procedure, no ostectomy is performed; however, minor osetoplasty may be done to modify the undesired bony architecture. 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. This incision is made 1mm to 2mm from the teeth. Posterior spinal fusion for adolescent idiopathic scoliosis using a convex pedicle screw technique; . Contents available in the book .

It is also known as the mucoperiosteal (mucosal tissue + periosteum) flap. b. Papilla preservation flap. Y5DDSEM1-Periodontology-2017-2018-MCQs Flashcards | Quizlet 5. The secondary flap removed, can be used as an autogenous connective tissue graft. 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. The square, Irrespective of performing any of the above stated surgical procedures, periodontal wound healing always begins with a blood clot in the space maintained by the closed flap after suturing 36. Contents available in the book .. The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. 2. 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 Following is the description of these flaps. After administrating local anesthesia, profound anesthesia is achieved in the area to be operated. Wood DL, Hoag PM, Donnenfeld OW, Rosenfeld LD. Apically-displaced Flap Trochleoplasty with a flexible osteochondral flap; The role of the width of the forefoot in the development of Morton's neuroma; February. If the dressing has to be placed, a dry foil is first placed over the flap before covering it with the dressing so that the displacement of the pack under the flap is prevented. An interdental (third) incision along the horizontal lines seen in the interdental spaces will sever these connections. 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. References are available in the hard-copy of the website. Perio-flap pptx - . - Muhadharaty A full-thickness flap is then elevated to expose 1-2 mm of the marginal bone. Areas which do not have an esthetic concern. Contents available in the book .. This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. 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). The antibiotics should be started before the surg-ical procedure so that appropriate antibiotic levels are there in blood at the time of surgery to prevent spread of infection. Re-inspection of the operated area is done to check for any deposits on the root surfaces, remaining granulation tissue or tissue tags which are removed, if detected. The first incision or the internal bevel incision is then made from the bleeding points directed at an apical level to the alveolar crest. This flap procedure causes the greatest probing depth reduction. The apically displaced flap is . 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 square . Gain access for osseous resective surgery, if necessary, 4. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. The internal bevel incisions are typically used in periodontal flap surgeries. Modified Widman flap and apically repositioned flap. 1. The proper placement of the flap margin at the toothbone junction during closure is important to prevent either recurrence of the pocket or the exposure of bone. With this incision, the gingiva containing pocket lining is separated from the tooth surface. Contents available in the book .. 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. International library review - 2022-2023| , , & - Academic Accelerator The triangular wedge of the tissue made by the above three incisions is then removed with the help of curettes. 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. 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). Management OF SOFT Tissues - MANAGEMENT OF SOFT TISSUES Tissue The techniques that are used to achieve reconstructive and regenerative objectives are the papilla preservation flap8 and the conventional flap, which involve only crevicular or pocket incisions. What is a periodontal flap? 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). These techniques are described in detail in Chapter 59. Smaller incisions usually cause less postoperative swelling and pain as compared to larger incisions. After thorough debridement, the area is then inspected for any remaining deposits on the root surfaces, granulation tissue or tissue tags. 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. The original intent of the surgery was to access the root surface for scaling and root planing. Contents available in the book .. The undisplaced (unrepositioned) flap improves accessibility for instrumentation, but it also removes the pocket wall, thereby reducing or eliminating the pocket. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. International library review - 2022-2023 | , The palatal flap offers a technically simple and predictable option for intraoral reconstruction. The vertical incisions are made from the center of palatal/lingual surfaces of teeth extending palatally/lingually. However, to do so, the attached gingiva must be totally separated from the underlying bone, thereby enabling the unattached portion of the gingiva to be movable. 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. 6. Severe hypersensitivity. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. The scalloping of the incision may not be accentuated as the flap has to be apically displaced and is not adapted interdentally. Once the interdental papilla is mobile, a blunt instrument is used to carefully push the interdental papilla through the embrasure. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. Table 1: showing thickness of gingiva in maxillary tooth region . According to flap reflection or tissue content: Suturing techniques for periodontal plastic surgery 12 or no. For the undisplaced flap, the internal bevel incision is initiated at or near a point just coronal to where the bottom of the pocket is projected on the outer surface of the gingiva (see Figure 59-1). During crown lengthening, the shape of the para-marginal incision depends on the desired crown length. Contents available in the book .. 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. The area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. Contents available in the book .. One incision is now placed perpendicular to these parallel incisions at their distal end. In this technique no. Papillae are then sutured with interrupted or horizontal mattress sutures. 3. Vertical incisions increase flap mobility, thus facilitating better access to the operative area. 7. With this access, the surgeon is able to make the. To perform this technique without creating a mucogingival problem it should be determined that enough attached gingiva will remain after after removal of pocket wall. Contents available in the book .. This incision is made from the crest of the gingival margin till the crest of alveolar bone. After one week, the sutures are removed and the area is irrigated with normal saline solution. May cause hypersensitivity. This incision is indicated in the following situations. PPTX The Flap Technique for Pocket Therapy The area is re-inspected for any remaining granulation tissue, tissue tags or deposits on the root surfaces. 1. Vascularized Thumb Metacarpal Periosteal Flap for Scaphoid Nonunion in Contents available in the book .. Scaling, root planing and osseous recontouring (if required) are carried out. 1. 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. Tooth with extremely unfavorable clinical crown/root ratio. . A. When the flap is returned and sutured in its original position. Because the alveolar bone is partially exposed, there is minimum post-operative pain and swelling. Intrabony pockets on distal areas of last molars. The soft tissue is then retracted with tissue forceps and the scoring incision is given to separate the periosteum from the bone. It was described by Kirkland in 1931 31. The vertical incision should always be placed at the line angles of the teeth and never (except rare instances, such as a double papilla flap) over the height of contour of the root. To improve esthetics as well as treat periodontal disease the method of choice remains is undisplaced flap surgery [12, 13]. 6. 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. To evaluate clinical and radiological outcomes after surgical treatment of scaphoid nonunion in adolescents with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF). The reasons for placing vertical incisions at line angles of the teeth are. The aim of this review is to determine the use of 3D printed technologies in the treatment of scaphoid fractures. Periodontal pockets in severe periodontal disease. Incisions used in papilla preservation flap using primary and secondary incisions. ), 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), on 59: The Flap Technique for Pocket Therapy, Several techniques can be used for the treatment of periodontal pockets. 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. The distance of the primary incision from the gingival margin depends on the thickness of the gingiva. Step 2: The mucogingival junction is assessed to determine the amount of keratinized tissue. Suturing is then performed to stabilize the flaps in their position. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. 1. The flaps may be thinned to allow for close adaptation of the gingiva around the entire circumference of the tooth and to each other interproximally. Contents available in the book .. Contents available in the book .. 3) The insertion of the guide-wire presents Flapless versus Conventional Flapped Dental Implant Surgery: A - PLOS Interrupted or continuous sling sutures are then placed to secure the flaps in their place. techniques revealed that 67.52% undergone kirkland flap, 20.51% undergone modified widman flap, 5.21% had papilla preservation flap, 2.25% had undisplaced flap, 1.55% had apically displaced flap and very less undergone distal wedge procedure which depicts that most commonly used flap technique was kirkland flap among other techniques. Once bone sounding has been done, a gingivectomy incision without bevel is given using a periodontal knife to remove the tissue above the alveolar crest. The horizontal or interdental incision is then made using a small knife (Orban 1 or 2), severing the supracrestal gingival fibers. Henry H. Takei, Fermin A. Carranza and Jonathan H. Do. 5. Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. The full-thickness mucoperiosteal flap procedure is the same as that described for the buccal and lingual aspects. Within the first few days, monocytes and macrophages start populating the area 37. The triangular wedge of the tissue, hence formed is removed. a. Full-thickness flap. This complete exposure of and access to the underlying bone is indicated when resective osseous surgery is contemplated. The patient is then recalled for suture removal after one week. Short anatomic crowns in the anterior region. 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. 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. Contents available in the book . The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. This is especially important because, on the palatal aspect, osseous deformities such as heavy bone ledges and exostoses are commonly seen. 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 secondary. that still persist between the bottom of the pocket and the crest of the bone. Contents available in the book . 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. 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%). 12D blade is usually used for this incision. The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. Incisions used in papilla preservation flap using primary, secondary and tertiary incisions. Depending on how the interdental papilla is managed, flaps can either split the papilla (conventional flap) or preserve it (papilla preservation flap). This suturing causes the apical positioning of the facial papilla, thus creating open gingival embrasures (black holes). Following shapes of the distal wedge have been proposed which are, 1. 1 and 2), the secondary inner flap is removed. When the flap is placed apically, coronally or laterally to its original position. 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. Normal interincisal opening is approximately 35-45mm, with mild . Incisions can be divided into two types: the horizontal and vertical incisions, Basic incisions used in periodontal surgeries, This internal bevel incision is placed at a distance from the gingival margin, directed towards the alveolar crest. The area is anesthetized and bone sounding is done to evaluate the osseous topography, pocket depth, and thickness of the gingiva. After it is removed there is minimum bleeding from the flaps as well as the exposed bone. 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. The Orban knife is usually used for this incision. The incisions given are the same as in case of modified Widman flap procedure. Contents available in the book .. Apically displaced flap. Crown lengthening procedures to expose restoration margins. 12 or no. The information presented in this website has been collected from various leading journals, books and websites. Palatal flap - PubMed The following statements can be made regarding periodontal regeneration procedures. After the area to be operated is irrigated with an anti-microbial solution, local anesthesia is applied and the area is isolated after profound anesthesia has been achieved. Evian et al. To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. The flap design may also be dictated by the aesthetic concerns of the area of surgery. 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. 6. 2011 Sep;25(1):4-15.

Flap | PDF | Periodontology | Surgery - Scribd Following is the description of step by step procedure followed while doing a modified Widman flap surgery. One incision is now placed perpendicular to these parallel incisions at their distal end. This drawback of conventional flap techniques led to the development of this flap technique which intended to spare the papilla instead of splitting it. 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 most abundant cells during the initial healing phase are the neutrophils. Incisions can be divided into two types: the horizontal and vertical incisions 7. The internal bevel incision is also known as reverse bevel incision because its bevel is in the reverse direction from that of the gingivectomy incision.
