Henry H. Takei, Fermin A. Carranza and Jonathan H. Do. Contents available in the book .. It is indicated when the flap has to be positioned apically and when the exposure of the bone is not required. 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. 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. 3. The most likely etiologic factor is local anesthetic, secondary to an inferior alveolar nerve block that penetrates the medial pterygoid muscle. The bleeding is frequently associated with pain. 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. 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 starting point on the gingiva is determined by whether the flap is apically displaced or not displaced (Figure 57-7). After the primary incision, tissue can now be retracted with the help of rat-tail pliers. The periodontal flap surgeries have been practiced for more than one hundred years now, since their introduction in the early 1900s. These techniques are described in detail in. Conventional flaps include the modified Widman flap, the undisplaced flap, the apically displaced flap, and the flap for reconstructive procedures. The incisions made should be reverse bevel to achieve thinning of tissue so that an adequate final approximation of the flaps can be achieved. 15 or 15C surgical blade is used most often to make this incision. 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). Contraindications of periodontal flap surgery. Reconstruction of Distal Phalangeal Soft Tissue Defects with Reverse Homodigital Artery Island Flap, , 2014-11, () . The area is then irrigated with normal saline and flaps are adapted back in position. 15 scalpel blade is used to make a triangular incision distal to the molar on retromolar pad area or the maxillary tuberosity. Contents available in the book . They are also useful for treating moderate to deep periodontal pockets in the posterior regions. 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. 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. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. Because the alveolar bone is partially exposed, there is minimum post-operative pain and swelling. Horizontal incisions are directed along the margin of the gingiva in a mesial or distal direction. b. Papilla preservation flap. Chlorhexidine rinse 0.2% bid . Within the first few days, monocytes and macrophages start populating the area, Post-operative complications after periodontal flap surgery, Hemorrhage occurring after 7-14 days is secondary to trauma or surgery. Tooth with marked mobility and severe attachment loss. a. 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). Conventional flap. The root surfaces are checked and then scaled and planed, if needed (Figure 59-3, G and H). Undisplaced femoral neck fractures in children have a high risk of secondary displacement. 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. ( intently, the undisplaced flap is perhaps the most commonly performed type ol periodontal surgery. 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 (. 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. C. According to flap placement after surgery: Depending on the purpose, it can be a full . The modified Widman flap is indicated in cases of perio-dontitis with pocket depths of 5-7 mm. 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 triangular wedge of the tissue, hence formed is removed. Apically displaced flaps have the important advantage of preserving the outer portion of the pocket wall and transforming it into attached gingiva. - Charter's method - Bass method - Still man method - Both a and b correct .

If the incisions have been made correctly, the flap will be at the crest of the bone with the scalloped papillae positioned interproximally, thus permitting its primary closure. The meniscus comma sign has been described for displaced flap tears of the meniscus. 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. The vertical incision should be made in such a way that interdental papilla is completely preserved. Different suture techniques Course Duration : 8,9,10,15,16,17 Mar Early registration fees before15/2: 5500 L.E . Square, parallel, or H design.

The flaps are then replaced to their original position and sutured using interrupted or continuous sling sutures. Which of the following mucogingival surgical techniques is indicated in areas of narrow gingival recession adjacent to a wide band of attached gingiva that can be used as a donor site? free gingival autograft double papilla flap modified Widman flap laterally displaced (positioned . In areas with shallow periodontal pocket depth. 4. May cause hypersensitivity. Contents available in the book .. 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. Background: Three-dimensional (3D) printing technology is increasingly commercially viable for pre-surgical planning, intraoperative templating, jig creation and customised implant manufacture. Contents available in the book .. The para-marginal internal bevel incision accomplishes three important objectives. Step 5:Tissue tags and granulation tissue are removed with a curette. Following are the steps followed during this procedure. May cause attachment loss due to surgery. The granulation tissue and the pocket lining may be then separated from the inner surface of the reflected flap with the help of surgical scissors and a scalpel. Its final position is not determined by the placement of the first incision. The no. This incision is made 1mm to 2mm from the teeth. Contents available in the book .. the.undisplaced flap and the gingivectomy. Signs and symptoms may include continuous flow, oozing or expectoration of blood or copious pink saliva. The location of the primary incision is based on the thickness of the gingiva, width of attached gingiva, the contour of the gingival margins, surgical objectives, and esthetic considerations. Contents available in the book .. 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 blade is pushed into the sulcus till resistance is felt from the crestal bone crest. 15 scalpel blade, parallel to each other beginning at the distal end of the edentulous area, continued to the tooth. - Undisplaced flap - Apicaliy displaced flap - All of the above - Modified Widman flap.

The bone remains covered by a layer of connective tissue that includes the periosteum. References are available in the hard-copy of the website. Within the first few days, monocytes and macrophages start populating the area 37. Periodontal pockets in severe periodontal disease. 3) The insertion of the guide-wire presents Suturing techniques. drg. Periodontal flaps involve the use of horizontal (mesialdistal) and vertical (occlusalapical) incisions. 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. (The use of this technique in palatal areas is considered in the discussion that follows this list. 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. To perform this technique without creating a mucogingival problem, the clinician should determine that enough attached gingiva will remain after removal of the pocket wall. 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. 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). Flap for regenerative procedures. The main disadvantage of this procedure is that healing in the interdental areas takes place by secondary intention. It is contraindicated in areas where the width of attached gingiva would be reduced to < 3 mm. 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. (1995, 1999) 29, 30 described . 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. Sutures are removed after one week and the area is irrigated with normal saline. The coronally directed incision is designated as external bevel incision whereas the apically directed incisions are the internal bevel and sulcular incision. May cause esthetic problems due to root exposure. One technique includes semilunar incisions which are . Evian et al. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively. After it is removed there is minimum bleeding from the flaps as well as the exposed bone. Diagram showing the location of two different areas where the internal bevel incision is made in an undisplaced flap. The secondary incision is given from the depth of the periodontal pocket till the alveolar crest. Wood DL, Hoag PM, Donnenfeld OW, Rosenfeld LD. Two types of horizontal incisions have been recommended: the internal bevel incision. The area to be operated is then isolated with the help of gauge. Rough handling of the tissue and long duration of the surgery commonly result in post-operative swelling. This is a commonly used incision during periodontal flap surgeries. Contents available in the book .. What are the steps involved in the Apically Displaced flap technique? 6. Step 6:Bone architecture is not corrected unless it prevents good tissue adaptation to the necks of the teeth. Incisions used in papilla preservation flap using primary, secondary and tertiary incisions. Journal of clinical periodontology. Patients at high risk for caries. In this flap procedure, no ostectomy is performed; however, minor osetoplasty may be done to modify the undesired bony architecture. In addition, the interdental incision is performed after the flap is elevated to remove the interdental tissue. Incisions used in papilla preservation flap using primary and secondary incisions. This flap procedure causes the greatest probing depth reduction. Minimally invasive techniques have recently been described for the reduction of the isolated anterior frontal sinus fracture via a closed approach. This incision is indicated in the following situations. After pushing the papillae buccally, both the flap and the papilla are reflected off the bone with a periosteal elevator. 2. 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. 1. 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. 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. 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. Furthermore, the access to the bone defects facilitates the execution of various regenerative procedures. Position of the knife to perform the internal bevel incision. See Page 1 After removing the wedge of the tissue the margins of the flap are undermined with the help of scalpel blades . After administration of local anesthesia, bone sounding is done to assess the thickness of gingiva and underlying osseous topography. The area is then re-inspected for any remaining granulation tissue, tissue tags and deposits on root surfaces. The internal bevel incisions are typically used in periodontal flap surgeries. The undisplaced flap and gingivectomy are the two techniques that surgically removed the pocket wall. Contents available in the book . The internal bevel incision in an undisplaced flap procedure is started at the same point where an external bevel incision is started in agingivectomyprocedure. 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. Locations of the internal bevel incisions for the different types of flaps. Periodontal flaps can be classified as follows. The flap was repositioned and sutured [Figure 6]. Areas where post-operative maintenance can be most effectively done by doing this procedure. Step 2:The gingiva is reflected with a periosteal elevator (Figure 59-3, D). 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. 15c or No. After the gingivectomy incision, primary and the secondary incisions are placed in the same way as described in the partial-thickness flap procedure. Some clinicians prefer curettes (Molt 2 curette) or chisels (Ochsenbein No. The flap design may also be dictated by the aesthetic concerns of the area of surgery. It allows the vertical incision to be sutured without stretching the flap over the cervical convexity of the tooth. Periodontal flap surgery with conventional incision commonly results in gingival recession and loss of interdental papillae after treatment. The term gingival ablation indicates? Conventional flaps include the. This flap procedure utilizes two incisions referred to as primary and secondary incisions which contain tissue which has to be removed. Interrupted or continuous sling sutures are then placed to secure the flaps in their place. 1972 Mar;43(3):141-4. Placing periodontal depressing is optional. The bleeding may range from a minor leakage or oozing, to extensive or frank bleeding at the surgical site. Tooth with extremely unfavorable clinical crown/root ratio. By doing this, the periosteum is cut and it becomes easy to remove the secondary flap from the bone. The blood clot provides a framework for the proliferation and migration of cells from surrounding tissues including gingiva, periodontal ligament (PDL), cementum, and alveolar bone 38. A technique using a mixture of bone dust and blood is called as a. bone blend technique b. bone swaging technique The interdental incision is then made to severe the inter-dental fiber attachment. Contents available in the book . 3. 2011 Sep;25(1):4-15. The periosteum left on the bone may also be used for suturing the flap when it is displaced apically. Clubbing Tar Staining Signs of other disease Hands warm and well perfused Salbutamol and CO2 retention flap Radial rate and rhythm respiratory rate Pattern of breathing ASK FOR BP FACE Eye . 16: 199-203 . 3. In the present discussion, we discussed various flap procedures that are used to achieve these goals. Most commonly done suturing is the interrupted suturing. Contents available in the book .. In areas with thin gingiva and alveolar process. 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 flap was repositioned and sutured and . The internal bevel incision should be scalloped into the interdental area to preserve the interdental papilla (see Figure 59-2). An interdental (third) incision along the horizontal lines seen in the interdental spaces will sever these connections. Our main aim of doing so is to get complete access to the root surfaces of the teeth and bone defects around the teeth. Contents available in the book .. This complete exposure of and access to the underlying bone is indicated when resective osseous surgery is contemplated. Hereditary gingival fibromatosis (HGF), also known as idiopathic gingival hyperplasia, is a rare condition of gingival overgrowth. Contents available in the book .. A periosteal elevator is inserted into the initial internal bevel incision, and the flap is separated from the bone. To evaluate clinical and radiological outcomes after surgical treatment of scaphoid nonunion in adolescents with a vascularized thumb metacarpal periosteal pedicled flap (VTMPF).

Chlorhexidine rinse 0.2% bid was prescribed for 2 weeks, along with analgesics and the patient was given appropriate . In 1973, App 25 reported a similar technique and termed it as Intact Papilla Flap which retained the interdental gingiva in the buccal flap. 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. This incision can be accomplished only if sufficient attached gingiva remains apical to the incision. Step 2: The initial, or internal bevel, incision is made. Local anesthesia is administered to achieve profound anes-thesia in the area to be operated. Therefore, the two anatomic landmarksthe pocket depth and the location of the mucogingival junctionmust be considered to evaluate the amount of attached gingiva that will remain after the surgery has been completed. Undisplaced flap, These . Myocardial infarction / stroke within 6 months. The horizontal incisions are used to separate the gingiva from the root surfaces of teeth. With the conventional flap, the interdental papilla is split beneath the contact point of the two approximating teeth to allow for the reflection of the buccal and lingual flaps. Vertical incisions increase flap mobility, thus facilitating better access to the operative area. The deposits on the root surfaces are removed and root planing is done. 19. 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. 1. Henry H. Takei, Fermin A. Carranza and Kitetsu Shin. Conventional flaps include: The modified Widman flap, The undisplaced flap, The apically displaced flap, The flap for regenerative procedures. Burkhardt R, Lang NP. Depending on how the interdental papilla is managed, flaps can either split the papilla (conventional flap) or preserve it (papilla preservation flap). As already stated, depending on the thickness of the gingiva, any of the following approaches can be used. The area is then irrigated with an antimicrobial solution. This procedure cannot be done on the palatal aspect as it has attached gingiva which cannot be displaced apically. Areas which do not have an esthetic concern. In this flap procedure, all the soft tissue, including the periosteum is reflected to expose the underlying bone. ), 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.

Minor osteoplasty may be carried out if osseous irregulari-ties are observed. Before we go into the details of the periodontal flap surgeries, let us discuss the incisions used in surgical periodontal therapy. This incision causes extensive loss of tissue and is indicated only in cases of gingival overgrowth. (2010) Factor V Leiden Mutation and Thrombotic Occlusion of Microsurgical Anastomosis After Free TRAM Flap. Tooth movement and implant esthetics. To preserve the present attached gingiva or even to establish an adequate strip of it, where it is narrow or absent. 15 scalpel blade is used to make a triangular incision distal to the molar on retromolar pad area or the maxillary tuberosity. The first step, Trismus is the inability to open the mouth. These, Historically, gingivectomy was the treatment of choice for these areas until 1966, when Robinson 32 addressed this problem and gave a separate surgical procedure for these areas which he termed, The triangular wedge technique is used in cases where the adequate zone of attached gingiva is present and in cases of short or small tuberosity. 1. Scalloping follows the gingival margin. Contents available in the book . 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). 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 conserves the relatively uninvolved outer surface of the gingiva. Itisnecessary toemphasise thefollowing points: I)Reaming ofthemedullary cavity wasnever employed. 34. When the flap is placed apically, coronally or laterally to its original position. 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. 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 granulation tissue, as well as tissue tags, are then removed. A. 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. The flap also allows the gingiva to be displaced to a different location in patients with mucogingival involvement. . 11 or 15c blade. Once the bone sounding has been done and the thickness of the gingiva has been established, the design of the flap is decided. The entire surgical procedure should be planned in every detail before the procedure is initiated. The modified Widman flap facilitates instrumentation for root therapy. 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. Apically displaced flap. 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. In areas with a narrow width of attached gingiva. The root surfaces are checked and then scaled and planed, if needed (. 2006 Aug;77(8):1452-7. This is termed. . Periodontal pockets in severe periodontal disease. To facilitate the close approximation of the flap, judicious osteoplasty, if required, is performed. These landmarks establish the presence and width of the attached gingiva, which is the basis for the decision. In the following discussion, we shall study in detail, the surgical techniques that are followed in various flap procedures. Displaced flap: 1. 61: Periodontal Regeneration and Reconstructive Surgery, 63: Periodontal Plastic and Esthetic Surgery, 59: The Flap Technique for Pocket Therapy, 55: General Principles of Periodontal Surgery, 31: Radiographic Aids in the Diagnosis of Periodontal Disease.
