Clinical and radiographic examination leading subsequently to diagnosis, remain the most important prerequisites permitting appropriate treatment. Several surgical techniques are available to uncover impacted/retained tooth according to their position within the osseous and dental environment. Moreover, to access to the tooth and to bond an orthodontic anchorage, the surgical techniques used during the surgical exposure must preserve the periodontium integrity. These surgical techniques are based on tissue manipulations derived from periodontal plastic surgery, permitting to establish and main- tain long-term periodontal health.

  • PERIODONTAL DISEASE Restoring the Health of Your Teeth and Gums
    502 Jefferson Highway N. Champlin, MN 55316 763 427-1311 www.moffittrestorativedentistry.com TREATING PERIODONTAL DISEASE Restoring the Health of Your Teeth and Gums YOUR GUMS NEED SPECIAL CARE Today, infection of the gums and supportive tissues surrounding the teeth (periodontal disease) can be controlled and in some cases even reversed. A variety of effective periodontal therapies are available to treat this disease, whether it has developed slowly or quickly. That’s why Dr. Moffitt may refer you to a periodontist—a specialist who can give your gums and teeth the special care they require. Working as part of your treatment team, your periodontist can help restore your mouth to a healthier condition and improve the chances of preserving your teeth. Your Gums Are in Trouble There are many telltale signs of periodontal disease: swollen, painful, or bleeding gums, bad breath, and loose or sensitive teeth. But gums don’t always let you know they’re in trouble, even in the late stages of disease. Bacterial infection may be silently and progressively destroying the soft tissues and bone that support your teeth. Early diagnosis of periodontal disease, prompt treatment, and regular checkups bring the best results. Making a Lifelong Commitment Periodontal disease is a serious and often ongoing condition, so it takes a committed, on going treatment program to control it effectively. After a thorough evaluation, your periodontist will recommend the best course of professional treatment. Whether this means nonsurgical or surgical treatment, it always includes home care. The periodontal therapy you get in the office takes care of the infection you have now, and sets the stage for maintaining control.

It is classified with the “access flap operations” because the goal of the flap reflection is primarily to provide improved visual access to the periodontally involved tissues. The modified widman flap surgery is not aimed at surgical eradication of pocket walls, including bony walls. It is aimed at maximum healing in areas of previous periodontal pockets with minimum loss of periodontal tissues during and after the surgery.[6] KEYWORDS: Modified widman flap, Gingival enlargement.

  • Lasers in Periodontal Surgery 5 Allen S
    Lasers in Periodontal Surgery 5 Allen S. Honigman and John Sulewski 5.1 Introduction The term laser, which stands for light amplification by stimulation of emitted radia- tion, refers to the production of a coherent form of light, usually of a single wave- length. In dentistry, clinical lasers emit either visible or infrared light energy (nonionizing forms of radiation) for surgical, photobiomodulatory, and diagnostic purposes. Investigations into the possible intraoral uses of lasers began in the 1960s, not long after the first laser was developed by American physicist Theodore H. Maiman in 1960 [1]. Reports of clinical applications in periodontology and oral surgery became evident in the 1980s and 1990s. Since then, the use of lasers in dental prac- tice has become increasingly widespread. 5.2 Laser-Tissue Interactions The primary laser-tissue interaction in soft tissue surgery is thermal, whereby the laser light energy is converted to heat. This occurs either when the target tissue itself directly absorbs the laser energy or when heat is conducted to the tissue from con- tact with a hot fiber tip that has been heated by laser energy. Laser photothermal reactions in soft tissue include incision, excision, vaporization, ablation, hemosta- sis, and coagulation. Table 5.1 summarizes the effects of temperature on soft tissue. A. S.

Recent Findings Surgical procedures for peri-implantitis treatment include two main approaches: non-augmentative and aug- mentative therapy. Open flap debridement (OFD) and resective treatment are non-augmentative techniques that are indicated in the presence of horizontal bone loss in aesthetically nondemanding areas. Implantoplasty performed adjunctively at supracrestally and buccally exposed rough implant surfaces has been shown to efficiently attenuate soft tissue inflammation compared to control sites. However, this was followed by more pronounced soft tissue recession. Adjunctive augmentative measures are recommended at peri-implantitis sites exhibiting intrabony defects with a minimum depth of 3 mm and in the presence of keratinized mucosa. In more advanced cases with combined defect configurations, a combination of augmentative therapy and implantoplasty at exposed rough implant surfaces beyond the bony envelope is feasible. Summary For the time being, no particular surgical protocol or material can be considered as superior in terms of long-term peri- implant tissue stability. Keywords Peri-implantitis . Treatment .

Chronic periodontitis patients on low dose aspirin were randomized into test (diode laser application after flap surgery) and control( flap surgery without laser ). The results showed less blood volume lost and better clinical improvements in the test sites. Henceforth the study has proved that lasers can form an integral part of periodontal therapy in patients on low dose aspirin(<150mg) without altering their drug regime. -------------------------------------------------------------------------------------------------------------------------------------- Date of Submission: 17-12-2019 Date of Acceptance: 31-12-2019 --------------------------------------------------------------------------------------------------------------------------------------- I. Introduction NSAIDs, especially low dose aspirin are one of the frequently prescribed drugs particularly in patients prone to cardio-vascular disorders and arthritis.

  • Modified Widman Flap (MWF)
    295_322_neu.qxd 24.03.2005 13:55 Uhr Seite 309 309 “Access Flap” Surgery, Open Flap Debridement (OFD)— Modified Widman Flap (MWF) Of the numerous periodontal surgical techniques, the oft-modified Widman flap (“Modified Wid- man Flap,” MWF) remains the standard procedure for open periodontitis therapy (Widman 1918, Ramfjord & Nissle 1974, Ramfjord 1977). It is classified with the “access flap operations” because the goal of the flap reflection is primarily to provide improved visual access to the periodontally involved tissues. The method is characterized by precise incisions, partial flap reflection and an atraumatic proce- dure, whose goal is not necessarily pocket elimination but “healing” (regeneration or a long junc- tional epithelium) of the periodontal pocket with minimum tissue loss. Because the alveolar process is only partially exposed, post-operative pain and swelling are rare. The main goals of the procedure include optimum mechanical subgingival root planing and “de- contamination” with direct vision, as well as healing by primary intention following close inter- dental flap adaptation. No ostectomy is performed. However, minor contouring osteoplasty can be performed to improve the facial or oral osseous morphology, primarily to achieve the desired in- terdental defect closure. Indications Contraindications • The MWF is indicated for the treatment of all types of per- There are but few contraindications for the MWF: iodontitis, but is especially effective with pocket depths of 5–7 mm. • Lack of or very thin and narrow attached gingiva can • Dependent upon the pathomorphologic situation on the render the technique difficult, because a narrow band of individual teeth, the MWF may be combined with larger attached gingiva does not permit the initial scalloped in- and fully reflected flaps (resective methods) and special cision (internal gingivectomy).
