In 1973, App 25 reported a similar technique and termed it as Intact Papilla Flap which retained the interdental gingiva in the buccal flap. Undisplaced flap, This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. 12 or no. Position of the knife to perform the internal bevel incision. Currently, the undisplaced flap may be the most frequently performed type of periodontal surgery. Depending on how the interdental papilla is managed, flaps can either split the papilla (conventional flap) or preserve it (papilla preservation flap). Contents available in the book .. The bleeding may range from a minor leakage or oozing, to extensive or frank bleeding at the surgical site. Areas where greater probing depth reduction is required. Interrupted or continuous sling sutures are then placed to secure the flaps in their place. The interdental incision is then made to severe the inter-dental fiber attachment. The choice of which procedure to use depends on two important anatomic landmarks: the pocket depth and the location of the mucogingival junction. Care should be taken to insert the blade in such a way that the papilla is left with a thickness similar to that of the remaining facial flap. drg. Flaps are used for pocket therapy to accomplish the following: 1. The incisions given are the same as in case of modified Widman flap procedure. The key point to be remembered here is, more the thickness of the gingiva more scalloped is the incision. preservation flap ) papila interdental tidak terpotong karena tercakup ke salah satu flep (gambar 2C). 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. In areas with thin gingiva and alveolar process. 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. Which is the best method of brushing technique preferred for the patient with orthodontic appliance: ? Contents available in the book .. Internal bevel and is 0.5-1.0mm from gingival margin Modified Widman Flap in 1985 28 introduced a detailed description of the surgical approach reported earlier by Genon and named the technique as Papilla Preservation Flap. Also, complicated or prolonged surgical procedures that require full-thickness mucoperiosteal flaps with resultant edema can lead to trismus. This should include the type of flap, the exact location and type of incisions, the management of the underlying bone, and the final closure of the flap and sutures. Following is the description of marginal and para-marginal internal bevel incisions. (1995, 1999) 29, 30 described . Minor osseous recontouring may be done and the flap is then adapted into the interdental areas. The incision is then carried out till the line angle of the tooth blending it into the gingival crevice. This flap procedure is indicated in areas that do not have esthetic concerns and areas where a greater reduction in pocket depth is desired. Contents available in the book . 3) The insertion of the guide-wire presents 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. Unrealistic patient expectations or desires. The granulation tissue, as well as tissue tags, are then removed. After suturing, the flap is adapted around the neck of the teeth with the help of moistened gauze. 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, 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, The techniques that are used to achieve reconstructive and regenerative objectives are the, The initial incision is an internal bevel incision to the alveolar crest starting 0.5mm to 1mm away from the gingival margin (, The gingiva is reflected with a periosteal elevator (. Square, parallel, or H design. Triangular 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. Scalloping follows the gingival margin. The esthetic and functional demands of maxillofacial reconstruction have driven the evolution of an array of options. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. The process of healing progresses through various phases of . This is mainly because of the reason that all the lateral blood supply to . b. Split-thickness flap. Our main aim of doing so is to get complete access to the root surfaces of the teeth and bone defects around the teeth. 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 57-4). Trombelli L, Farina R. Flap designs for periodontal healing. Therefore, these flaps accomplish the double objective of eliminating the pocket and increasing the width of the attached gingiva. The aim of this review is to determine the use of 3D printed technologies in the treatment of scaphoid fractures. that still persist between the bottom of the pocket and the crest of the bone. At last periodontal dressing may be applied to cover the operated area. Apically displaced flap, and The partial-thickness flap is indicated when the flap is to be positioned apically or when the operator does not want to expose bone. The periosteum left on the bone may also be used for suturing the flap when it is displaced apically. 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. In another technique, vertical incisions and a horizontal incision are placed. 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. The incision is made. Methods Twelve patients younger than 18 years with scaphoid nonunion, who underwent a VTMPF procedure without bone grafting , were included for this prospective cohort . 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. Undisplaced flap and apically repositioned flap. 74. After one week, the sutures are removed and the area is irrigated with normal saline solution. 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. The root surfaces are checked and then scaled and planed, if needed (Figure 59-3, G and H). After it is removed there is minimum bleeding from the flaps as well as the exposed bone. These landmarks establish the presence and width of the attached gingiva, which is the basis for the decision. Table 1: showing thickness of gingiva in maxillary tooth region . The internal bevel incision is basic to most periodontal flap procedures. 1. Any excess blood is expressed and an intimate adaptation of the flap to the teeth and the alveolus is ensured. Step 2: The mucogingival junction is assessed to determine the amount of keratinized tissue. Conventional flaps include the. This flap procedure allows complete access to the root surfaces allowing their mechanical debridement and decontamination under direct vision. Incisions used in papilla preservation flap using primary and secondary incisions. 2) by pushing the instrument in the interdental area and twisting it to remove the infected granulomatous tissue. Intrabony pockets on distal areas of last molars. Severe hypersensitivity. Coronally displaced flap. The triangular wedge of the tissue, hence formed is removed. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. These vertical incisions are now joined with a horizontal incision as shown in the following figure. Periodontal pockets in areas where esthetics is critical. It produces a sharp, thin flap margin for adaptation to the bone-tooth junction. The information presented in this website has been collected from various leading journals, books and websites. Along with removing the tissue above the alveolar crest, this incision also reveals the thickness of the soft tissue. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. 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 esthetic problems due to root exposure. Two basic flap designs are used. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . In this technique no. Background: Three-dimensional (3D) printing technology is increasingly commercially viable for pre-surgical planning, intraoperative templating, jig creation and customised implant manufacture. 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. The flap was repositioned and sutured [Figure 6]. Some clinicians prefer curettes (Molt 2 curette) or chisels (Ochsenbein No. Myocardial infarction / stroke within 6 months. The aim of this study was to test the null hypothesis of no difference in the implant failure rates, postoperative infection, and marginal bone loss for patients being rehabilitated by dental implants being inserted by a flapless surgical procedure versus the open flap technique, against the alternative hypothesis of a difference. Contents available in the book .. Contents available in the book .. Suturing is then performed to stabilize 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. The area is then irrigated with normal saline and flaps are adapted back in position. 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. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. Conventional surgical approaches include the coronal flap, direct cutaneous incision, and endoscopic techniques. Crown lengthening procedures to expose restoration margins. The granulation tissue is highly vascularized, so it bleeds profusely. The most abundant cells during the initial healing phase are the neutrophils. 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 area is then debrided for all the granulation tissue present and scaling and root planing of the root surfaces are carried out. Loss of marginal bone as a result of uncovering the osseous crest. Contents available in the book .. Contents available in the book . 3. The internal bevel incision accomplishes three important objectives: (1) it removes the pocket lining; (2) it conserves the relatively uninvolved outer surface of the gingiva, which, if apically positioned, becomes attached gingiva; and (3) it produces a sharp, thin flap margin for adaptation to the bonetooth junction. It is also known as the mucoperiosteal (mucosal tissue + periosteum) flap.

The incision is made . In areas with shallow periodontal pocket depth. 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. It is discarded after the crevicular (second) and interdental (third) incisions are performed (Figure 57-5). This drawback of conventional flap techniques led to the development of this flap technique which intended to spare the papilla instead of splitting it. 2006 Aug;77(8):1452-7. Contents available in the book .. 4. 35. Areas where greater probing depth reduction is required. To fulfill these purposes, several flap techniques are available and in current use. 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. 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. Periodontal flap surgery with conventional incision commonly results in gingival recession and loss of interdental papillae after treatment. After debridement, flaps are closely adapted around the teeth in close approximation, allowing healing by primary intention. It does not attempt to reduce the pocket depth, but it does eliminate the pocket lining. The three incisions necessary for flap surgery. During crown lengthening, the shape of the para-marginal incision depends on the desired crown length. 7. In these flaps, the entire papilla is incorporated into one of the flaps. To overcome the problem of recession, papilla preservation flap design is used in these areas. Position of the knife to perform the crevicular (second) incision. It is most commonly caused due to infection and sloughing of blood vessels. 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. Contents available in the book . Contents available in the book .. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. By doing this, the periosteum is cut and it becomes easy to remove the secondary flap from the bone. Wood DL, Hoag PM, Donnenfeld OW, Rosenfeld LD. Modified Widman flap, A full-thickness flap is then elevated to expose 1-2 mm of the marginal bone. Our courses are designed to. Flap design for a conventional or traditional flap technique. Contents available in the book .. 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. This suturing causes the apical positioning of the facial papilla, thus creating open gingival embrasures (black holes). The vertical incisions are extended far enough apically so that they are at least 3 mm apical to the margin of the interproximal bony defect and 5 mm from the gingival margin. 6. Step 3: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. Undisplaced (replaced) flap This type of periodontal flap Apically positions pocket wall and preserves keratinized gingiva by apically positioning Apically displaced (positioned) flap This type of incision is used for what type of flap? The first documented report of papilla preservation procedure was by Kromer 24 in 1956, which was designed to retain osseous implants. To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. The internal bevel incisions are typically used in periodontal flap surgeries. Preservation of good blood supply to the flap is another important consideration. The apically displaced flap technique is selected for cases that present a minimal amount of keratinized, attached gingiva. 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 interdental incision is then given to remove the wedge of tissue that contains the pocket wall. With this incision, the gingiva containing pocket lining is separated from the tooth surface. Contents available in the book .. Different Flap techniques for treatment of gingival recession (Lateral-coronal-double papilla-semilunar-tunnel-apical). a. Non-displaced flap. Periodontal maintenance (Supportive periodontal therapy), Orthodontic-periodontal interrelationship, Piezosurgery in periodontics and oral implantology. 5. 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. A Technique to Obtain Primary Intention Healing in Pocket Elimination Adjacent to an Edentulous Area Article Jan 1964 G. Kramer M. Schwarz View Mucogingival Surgery: The Apically Repositioned. A. The term gingival ablation indicates? 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 . The flap was repositioned and sutured and . To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. 1. Several techniques such as gingivectomy, undisplaced flap with or without osseous surgery, apically repositioned flap . Modified flap operation, The deposits on the root surfaces are removed and root planing is done. The objectives for the other two flap proceduresthe undisplaced flap and the apically displaced flapinclude root surface access and the reduction or elimination of the pocket depth. Short anatomic crowns in the anterior region. The patient is then recalled for suture removal after one week. The area is then irrigated with an antimicrobial solution. Contents available in the book .. Within the first few days, monocytes and macrophages start populating the area 37. 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. Need to visually examine the area, to make a definite diagnosis. Contents available in the book . This approach was described by Staffileno (1969) 23. In case where the soft tissue is quite thick, this incision. To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. The clearly visible root surfaces and osseous defects are then debrided with the help of hand (curettes) and ultrasonic (ultrasonic scalers) instruments. With the help of Ochsenbein chisels (no. 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). May cause attachment loss due to surgery. These are indicated in cases where interdental spaces are too narrow and when the flap needs to be displaced. Chlorhexidine rinse 0.2% bid . Later on Cortellini et al. Mitral facies or malar flush There is a tapping apex beat which is undisplaced. See Page 1 Contents available in the book .. b. The vertical incisions are made from the center of palatal/lingual surfaces of teeth extending palatally/lingually. No incision is made through the interdental papillae. In case of periodontitis with active pockets 5-6 mm deep or greater, that do not respond satisfactorily to the initial therapy. Osseous surgical procedures with very deep osseous defects and irregular bone loss, facially and lingually/ palatally. ), Only gold members can continue reading. Tooth with extremely unfavorable clinical crown/root ratio. This website is a small attempt to create an easy approach to understand periodontology for the students who are facing difficulties during the graduation and the post-graduation courses in our field. 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. 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. Periodontal flaps can be classified as follows. If detected, they are removed. Apically-displaced Flap Contents available in the book .. The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). 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. . Eliminate or reduce pocket depth via resection of the pocket wall, 3. Undisplaced flaps are one of the most common periodontal surgeries for correcting anatomical factors that predispose patients to predisposing periodontal disease, and makes it possible to improve aesthetics by eliminating obstacle of wearing a denture. Sulcular incision is now made around the tooth to facilitate flap elevation. In areas with a narrow width of attached gingiva. 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, Periodontal flap surgeries are also done for the establishment of. 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. 1972 Mar;43(3):141-4. Normal interincisal opening is approximately 35-45mm, with mild . Modified Widman flap and apically repositioned flap. The full-thickness mucoperiosteal flap procedure is the same as that described for the buccal and lingual aspects. Flap adaptation is then done with the help of moistened gauze and any excess blood is expressed. This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. 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. - Charter's method - Bass method - Still man method - Both a and b correct . 12D blade is usually used for this incision. Swelling is another common complication after flap surgery. Contents available in the book .. The root surfaces are checked and then scaled and planed, if needed (. The step-by-step technique for the undisplaced flap is as follows: Step 1: The periodontal probe is inserted into the gingival crevice & penetrates the junctional epithelium & connective tissue down to bone. 34. 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. In the present discussion, we discussed various flap procedures that are used to achieve these goals. The gingival margin is removed, and the flap is reflected to gain access for root therapy. Increase accessibility to root deposits for scaling and root planing, 2. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. 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 internal bevel incision is also known as reverse bevel incision because its bevel is in the reverse direction from that of the gingivectomy incision. Henry H. Takei, Fermin A. Carranza and Jonathan H. Do. 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. Alveolar crest reduction following full and partial thickness flaps. After the removal of the secondary flap, scaling and root planing is done and the flap is adapted to its position. (The use of this technique in palatal areas is considered in the discussion that follows this list. Contents available in the book .. 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 area is then irrigated with an antimicrobial solution. The narrow width of attached gingiva which may further reduce post-operatively. It enhances the potential for effective periodontal maintenance and preservation of attachment levels. APICALLY REPOSITIONED FLAP/ PERIODONTAL FLAP SURGICAL TECHNIQUE/ DR. ANKITA KOTECHA 17,228 views Jul 30, 2020 This video is about APICALLY REPOSITIONED FLAP .more Dislike Share dental studies. Following are the steps followed during this procedure. The secondary flap removed, can be used as an autogenous connective tissue graft. 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. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. 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. Scaling, root planing and osseous recontouring (if required) are carried out. Fugazzotto PA. There have been a lot of modifications and improvisations in various periodontal surgical techniques during this period. After the flap has been elevated, a wedge of tissue remains on the teeth and is attached by the base of the papillae. Contents available in the book . Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. 1. The modified Widman flap procedure involves placement of three incisions: the initial internal bevel/ reverse bevel incision (first incision), the sulcular/crevicular incision (second incision) and the horizontal/interdental incision (third incision). . These techniques are described in detail in Chapter 59. Conventional flap. In non-esthetic areas with moderate to deep pockets and for crown lengthening, this incision is indicated. Step 2:The initial or internal bevel incision is made (Figure 59-4) after scalloping the bleeding marks on the gingiva (Figure 59-5). Contents available in the book . 7. This flap procedure causes the greatest probing depth reduction.
