Comparison of intraoral donor sites for onlay grafting prior to implant placement.

Fifty patients with inadequate bone volume for implant placement were treated with mandibular bone grafts from the symphysis or ramus. The choice of donor site was determined by defect morphology and recipient site location. Although the harvest of bone was associated with low morbidity, the ramus donor site resulted in fewer complications. Implants were placed secondarily following a 4- to 6-month healing period. The onlay grafts exhibited minimal resorption and maintained their dense quality. The symphysis grafts were larger in overall volume, with a corticocancellous morphology. The ramus area provided essentially a cortical graft that was well suited for veneering ridge deficiencies; however, the surgical access in some cases was more difficult than in the anterior mandible.

[Calibrated autologous bone grafts--their use in oral implantology. Widening--crest augmentation. Personal technic].

Using special trephines moved by a rotary motor, corticospongy graded-cylindrical grafts can be obtained from the iliac crest. These grafts are used to maintain widened and raised maxillary or mandibular crests. Inserted between type Brane-mark implants is useful to increase the height of the alveolar process when it is impossible to implant. Surgical trauma is limited compared with other Lefort 1 type operations advocated for the same indication. Operative effects resolve quickly and patients are hospitalized less than two days. The entire process is quite economical.

The diagnosis and treatment of the gummy smile.

The diagnosis and treatment of the "gummy smile" (altered passive eruption, excessive gingival display) help the periodontist to provide the most beautiful smiles possible for patients. This article describes diagnosis, surgical planning, and case reports that show the benefits of treatment of this common clinical problem for the patient and restorative dentist who can now provide ideal cosmetic results for their patients.

Localized management of sinus floor with simultaneous implant placement: a clinical report.

Localized management of sinus floor (LMSF) achieves implant placement and sinus lifting simultaneously. LMSF is a further application of the principles of the edentulous ridge expansion (ERE) technique. It comprises the dissection of a partial-thickness flap, the buccal expansion of the residual alveolar bone, and the fracture and elevation of the sinus floor with simultaneous implant placement. Three hundred three patients were treated with 499 implants placed using the LMSF between April 1988 and December 1993. The selected patients, who showed no signs of sinus pathology, exhibited insufficient vertical alveolar bone dimensions for the placement of dental implants with the traditional technique. The minimal residual alveolar bone height was between 5 and 7 mm. Based on the criteria established by Albrektsson and his coworkers in 1986, the success rate of the 499 implants placed with the LMSF was 97.5%.

Prosthetic treatment using an osseointegrated implant after secondary bone grafting of a residual alveolar cleft: a case report.

Conventionally, for dental reconstruction after bone grafting of the congenital residual alveolar cleft, a fixed prosthesis or removable partial denture is used. In this paper, residual alveolar cleft reconstruction with an osseointegrated implant following secondary bone grafting is described. The patient underwent secondary bone grafting of the residual alveolar cleft at the age of 18 years. One osseointegrated implant was placed in the bone bridge 8 months after bone grafting. No problems up to 1 year after the fabrication and placement of the fixed prosthesis have been observed.

Periodontal plastic surgery.

Most periodontal esthetic procedures can be grouped into one of the following areas: crown lengthening, alveolar ridge preservation/augmentation, soft tissue grafts, and the correction of an open interproximal space. Soft tissue abnormalities, with the exception of the loss of the interproximal papilla, can be resolved predictably, improving esthetics and even creating restorative opportunities. In addition to a discussion of the pretreatment esthetic evaluation, an overview of periodontal plastic surgery procedures is presented, along with an example of the "Periodontal Enhancement Prescription," which facilitates communication between offices.

Biologic and clinical considerations for autografts and allografts in periodontal regeneration therapy.

Although complete periodontal regeneration is unpredictable with any regenerative therapy currently used, periodontal bone grafts show strong potential. A large body of clinical evidence clearly indicates that grafts consistently lead to better bone fill than nongrafted controls. Regardless of which material is used, the average bone fill is 3 mm, or about 60% defect fill according to reported studies. In addition, histologic analyses now show conclusively that regenerative treatment with bone grafting leads to some degree of regenerated bone, cementum, and periodontal ligament. Although bone grafts and other periodontal treatments have improved clinicians' ability to promote osteogeneration, the outcomes are still somewhat unpredictable. Part of the problem is that it is still unclear how periodontal disease affects the supporting bone's regenerative potential and what specific biologic factors are involved. In recent years, however, clinicians have begun to learn much more about how periodontal regeneration works on a cellular and molecular level. This is a key step to developing strategies and materials that allow clinicians to promote periodontal regeneration predictably. Since its introduction during the last decade, GTR has been an invaluable addition to the armamentarium, as has the recognized importance of early wound stability. As more is learned about the biologic process of periodontal regeneration, new materials and techniques, such as growth factors, absorbable membranes, and new graft materials, are expected to make the task of periodontal regeneration even more predictable. It is likely that some combination of techniques may eventually prove to yield the best results.

Algorithms for the treatment of cleft lip and palate.

Developing standardized outcomes and algorithms of treatment is a constantly evolving task. This article examines four variables in this process: cleft type, operative technique, surgical experience, and timing. Input from international cleft lip and palate programs regarding techniques and treatment modalities provide a dynamic tool for assessment and the development of guidelines in the treatment of the cleft lip and palate patient.
