Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. 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 . The incisions given are the same as in case of modified Widman flap procedure. To evaluate clinical and radiological outcomes after surgical treatment of scaphoid nonunion in adolescents with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF). 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. 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. This incision is not indicated unless the margin of the gingiva is quite thick. 2. Contents available in the book .. This incision is indicated in the following situations. 16: 199-203 . - Charter's method - Bass method - Still man method - Both a and b correct . 4. Contents available in the book . This is also known as. The first step, Trismus is the inability to open the mouth. Two basic flap designs are used. Step 5:Tissue tags and granulation tissue are removed with a curette. Endodontic Topics. DESCRIPTION. The use of continuous suturing in suture materials tearing through the flap edges and both plastic surgery (1) and periodontal surgery subsequent retraction of the flaps to less desirable has many advantages. 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. Modified flap operation, Tooth with extremely unfavorable clinical crown/root ratio. 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. Square, parallel, or H design. Following is the description of step by step procedure followed while doing a modified Widman flap surgery. The most apical end of the internal bevel incision is exposed and visible. Different Flap techniques for treatment of gingival recession (Lateral-coronal-double papilla-semilunar-tunnel-apical). - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap. To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. Normal interincisal opening is approximately 35-45mm, with mild, Periobasics A Textbook of Periodontics and Implantology, Text Book of Basic Sciences for MDS Students, History of surgical periodontal pocket therapy and osseous resective surgeries. Fractures of the frontal sinus are a common maxillofacial trauma and constitute 5-15% of all maxillofacial fractures. It was described by Kirkland in 1931 31. The square . The researchers reported similar results for each of the three methods tested. It is also known as a partial-thickness flap. Which is the best method of brushing technique preferred for the patient with orthodontic appliance: ? It can be used in combination with other procedures such as osseous resection, regenerative procedures, hemisection procedure and procedures involving wedge excision. 15c, 11 or 12d. The incision is made. Coronally displaced flap. Sulcular incision is now made around the tooth to facilitate flap elevation. According to management of papilla: See Page 1 The flap was repositioned and sutured [Figure 6]. The palatal flap offers a technically simple and predictable option for intraoral reconstruction. Step 2: The initial, internal bevel incision is made after the scalloping of the bleeding marks on the gingiva. The deposits on the root surfaces are removed and root planing is done. The soft tissue is then retracted with tissue forceps and the scoring incision is given to separate the periosteum from the bone. Suturing is then done using a continuous sling suture. The horizontal or interdental incision is then made using a small knife (Orban 1 or 2), severing the supracrestal gingival fibers. Periodontal flap surgeries are also done for the establishment of . Contents available in the book .. Journal of periodontology. In this technique no. There have been a lot of modifications and improvisations in various periodontal surgical techniques during this period. 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. 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. 6. A detailed description of the historical aspect of various flap surgeries has been given in the previous chapter. The intrasulcular incision is given using No. It conserves the relatively uninvolved outer surface of the gingiva. The meniscus comma sign has been described for displaced flap tears of the meniscus. After the gingivectomy incision, primary and the secondary incisions are placed in the same way as described in the partial-thickness flap procedure. 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. The beak-shaped no. in 1985 28 introduced a detailed description of the surgical approach reported earlier by Genon and named the technique as Papilla Preservation Flap. 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 .. b. Split-thickness flap. It is caused by trauma or spasm to the muscles of mastication. Our courses are designed to. 34. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. 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. In 1973, App 25 reported a similar technique and termed it as Intact Papilla Flap which retained the interdental gingiva in the buccal flap. 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. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. Rough handling of the tissue and long duration of the surgery commonly result in post-operative swelling. Apically-displaced Flap ), 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. Vertical incisions increase flap mobility, thus facilitating better access to the operative area. It is an access flap for the debridement of the root surfaces. 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 interdental incision is then given to remove the wedge of tissue that contains the pocket wall. This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. The challenging nature of scaphoid fracture and nonunion surgery make it an obvious target. The conventional flap is used (1) when the interdental spaces are too narrow, thereby precluding the possibility of preserving the papilla, and (2) when the flap is to be displaced. Contents available in the book .. The initial or the first incision is the internal bevel incision given not more than 1 mm from the crest of the gingiva and directed to the crest of the bone. After this, partial elevation of the flap is done with the help of a small periosteal elevator. These . These incisions are made in a horizontal direction and may be coronally or apically directed. The operated area will be cleaner without dressing and will heal faster. This flap procedure causes the greatest probing depth reduction. FLAP Flap yaitu suatu lembaran jaringan mukosa yang terdiri dari jaringan gingiva, mukosa alveolar, dan atau jaringan periosteum yang dilepaskan/ dissection dari permukaan tulang alveolar. Papillae are then sutured with interrupted or horizontal mattress sutures. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. Most commonly done suturing is the interrupted suturing. In this technique no. The full-thickness mucoperiosteal flap procedure is the same as that described for the buccal and lingual aspects. Periodontal flaps involve the use of horizontal (mesialdistal) and vertical (occlusalapical) incisions. One incision is now placed perpendicular to these parallel incisions at their distal end. In case where the soft tissue is quite thick, this incision. The design of the flap is dictated by the surgical judgment of the operator, and it may depend on the objectives of the procedure. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. May cause esthetic problems due to root exposure. Because the pocket wall is not displaced apically, the initial incision should eliminate the pocket wall. Need to visually examine the area, to make a definite diagnosis. The periodontal flap surgeries have been practiced for more than one hundred years now, since their introduction in the early 1900s. Periodontal maintenance (Supportive periodontal therapy), Orthodontic-periodontal interrelationship, Piezosurgery in periodontics and oral implantology. After these three incisions are made correctly, a triangular wedge of the tissue is obtained containing the inflamed connective . The incision is carried around the entire tooth. For the correction of bone morphology (osteoplasty, osseous resection). The following steps outline the undisplaced flap technique. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. . 12D blade is usually used for this incision. 1. Short anatomic crowns in the anterior region. A technique using a mixture of bone dust and blood is called as a. bone blend technique b. bone swaging technique After one week, the sutures are removed and the area is irrigated with normal saline solution. Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. 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. It differs from the modified Widman flap in that the soft-tissue pocket wall is removed with the initial incision; thus, it may be considered an internal bevel gingivectomy. The undisplaced flap and the gingivectomy are the two techniques that surgically remove the pocket wall. The undisplaced flap is therefore considered an internal bevel gingivectomy. The first documented report of papilla preservation procedure was by Kromer 24 in 1956, which was designed to retain osseous implants. (adsbygoogle = window.adsbygoogle || []).push({}); The external bevel incision is typically used in gingivectomy procedures. After suturing, the flap is adapted around the neck of the teeth with the help of moistened gauze. Thus, an incision should not be made too close to the tooth, because it will not eliminate the pocket wall, and it may result in the re-creation of the soft-tissue pocket. 6. Contents available in the book . This will allow better coverage of the bone at both the radicular and interdental areas. 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. As described in History of surgical periodontal pocket therapy and osseous resective surgeries the palatal approach for . . Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. 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. This is especially important in maxillary and mandibular anterior areas which have a prime esthetic concern. 5. The book is usually delivered within one week anywhere in India and within three weeks anywhere throughout the world. Following are the steps followed during this procedure. There is a loud S1 The murmur is a mid-diastolic rumbling heard best at . Once the interdental papilla is mobile, a blunt instrument is used to carefully push the interdental papilla through the embrasure. 12 or no. It protects the interdental papilla adjacent to the surgical site. 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 the upcoming chapters, we shall read about various regenerative procedures which are aimed at achieving regeneration of lost periodontal structures. May cause hypersensitivity. b. Contents available in the book .. Clinical crown lengthening in multiple teeth. 2. Fibrous enlargement is most common in areas of maxillary and mandibular . The bone remains covered by a layer of connective tissue that includes the periosteum. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. 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. 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. In these flaps, the entire papilla is incorporated into one of the flaps. drg. After the removal of the secondary flap, scaling and root planing is done and the flap is adapted to its position. The area is then irrigated with an antimicrobial solution. C. According to flap placement after surgery: Areas which do not have an esthetic concern. Incisions can be divided into two types: the horizontal and vertical incisions 7. This incision is indicated in the following situations. So, this procedure cannot be employed when modified Widman flap, excisional new attachment procedure and regenerative procedures such as osseous grafting are done because these procedures require primary closure. 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). Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. 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). The periodontal flap is one of the most frequently employed procedures, particularly for moderate and deep pockets in posterior areas (see Chapter 57). Contents available in the book ..

Chlorhexidine rinse 0.2% bid was prescribed for 2 weeks, along with analgesics and the patient was given appropriate . Contents available in the book .. To overcome the problem of recession, papilla preservation flap design is used in these areas. This type of incision, starting just below the bleeding points, removes the pocket wall completely. Swelling hinders routine working life of patient usually during the first 3 days after surgery 41. To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. Click this link to watch video of the surgery: Modified Widman Flap surgery. The following steps outline the modified Widman flap technique. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. In areas with shallow periodontal pocket depth. 11 or 15c blade. Flap design for a conventional or traditional flap technique. The scalloping of the incision may not be accentuated as the flap has to be apically displaced and is not adapted interdentally. 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. May cause attachment loss due to surgery. Suturing is then performed to stabilize the flaps in their position. The vertical incisions are made from the center of palatal/lingual surfaces of teeth extending palatally/lingually. Continuous suturing allows positions. See video of the surgery at: Modified flap operation. Alveolar crest reduction following full and partial thickness flaps. Preservation of good blood supply to the flap is another important consideration. It allows the vertical incision to be sutured without stretching the flap over the cervical convexity of the tooth. Contents available in the book . The primary incision is placed with the help of 15c blade, but in case of limited access, blade 12 d can be used. 2. The secondary flap removed, can be used as an autogenous connective tissue graft. The patient is then recalled for suture removal after one week. The buccal and palatal/lingual flaps are reflected with the help of a periosteal elevator. In areas with deep periodontal pockets and bone defects. Genon and Bender in 1984 27 also reported a similar technique indicated for esthetic purpose. 12 or no. Contents available in the book .. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. 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 beak-shaped no. If the tissue is too thick, the flap margin should be thinned with the initial incision. Contents available in the book .. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. Areas with sufficient band of attached gingiva. Both full-thickness and partial-thickness flaps can also be displaced. 4. Journal of clinical periodontology. 7. It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). A crescent-shaped incision is sometimes used during the crown lengthening procedure. Contents available in the book .. . in adults. a. 1972 Mar;43(3):141-4. Contents available in the book .. Contents available in the book .. 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. Papilla preservation flap. 4. 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. Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. The area is then irrigated with normal saline and flaps are adapted back in position. Position of the knife to perform the crevicular (second) incision. 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. The periodontal flap is one of the most frequently employed procedures, particularly for moderate and deep pockets in posterior areas (see, Increase accessibility to root deposits for scaling and root planing, Eliminate or reduce pocket depth via resection of the pocket wall, Gain access for osseous resective surgery, if necessary, Expose the area for the performance of regenerative methods, Technique for Access and Pocket Depth Reduction or Elimination, All three flap techniques that were just discussed involve the use of the basic incisions described in. 1. Incisions used in papilla preservation flap using primary, secondary and tertiary incisions. The starting point on the gingiva is determined by whether the flap is apically displaced or not displaced (Figure 57-7). 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.

The incision is then carried out till the line angle of the tooth blending it into the gingival crevice. For the management of the papilla, flaps can be conventional or papilla preservation flaps. Unsuitable for treatment of deep periodontal pockets. 7. 2006 Aug;77(8):1452-7. The interdental papilla is then freed from the underlying bone and is completely mobilized. The area is then irrigated with an antimicrobial solution. The partial-thickness flap may be necessary when the crestal bone margin is thin and exposed with an apically placed flap or when dehiscences or fenestrations are present. Furthermore, the access to the bone defects facilitates the execution of various regenerative procedures. After the primary incision, tissue can now be retracted with the help of rat-tail pliers. Trombelli L, Farina R. Flap designs for periodontal healing. The triangular wedge of the tissue, hence formed is removed. May cause attachment loss due to surgery. Contents available in the book . It is most commonly caused due to infection and sloughing of blood vessels. A small periosteal elevator or Molt 2/4 curette can be used for this purpose. Two types of horizontal incisions have been recommended: the internal bevel incision. 3. 15 or 15C surgical blade is used most often to make this incision. 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. 2. that still persist between the bottom of the pocket and the crest of the bone. 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. At last periodontal dressing may be applied to cover the operated area. Platelets rich fibrin (PRF) preparation and application in the . In Figure 2, the frequency of the types of flap surgical techniques followed were analyzed. One technique includes semilunar incisions which are . The incision is carried around the entire tooth. Evian et al. Ahmad Syaify, Sp.Perio (K) Spesialis Konsultan Bedah Perio & Estetik. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. B. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. As described in, Image showing primay and secondary incisions used in ledge and wedge technique. In other words, we can say that. 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 buccal and the lingual/palatal flaps are then elevated to expose the diseased root surfaces and the marginal bone. Severe hypersensitivity. Contents available in the book .. Following is the description of marginal and para-marginal internal bevel incisions. 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. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. In non-esthetic areas with moderate to deep pockets and for crown lengthening, this incision is indicated. The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. The periodontal dressing is not required if the flap has been adapted adequately to cover the interdental area. Contents available in the book .. Trismus is the inability to open the mouth. Contents available in the book . 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.
