ABSTRACT
A retrospective clinical evaluation of patients consecutively treated from multiple centers was performed. The treatment of these patients utilized the bone-added osteotome sinus floor elevation (BAOSFE) procedure with immediate implant fixation. The BAOSFE method employs a specific set of osteotome instruments to tent the sinus membrane with bone graft material placed through the osteotomy site. A total of 174 implants was placed in 101 patients. Implants were of both screw and cylinder shapes with machined, titanium plasma-sprayed, and hydroxyapatite surfaces from various manufacturers. The 9 participating clinicians used autografts, allografts, and xenografts alone or in various combinations, and the type of graft was selected by the individual clinicians. The choice of graft material did not appear to influence survival rates. Loading periods varied from 6 to 66 months. The survival rate was 96% or higher when pretreatment bone height was 5 mm or more and dropped to 85.7% when pretreatment bone height was 4 mm or less. The most important factor influencing implant survival with the BAOSFE was the preexisting bone height between the sinus floor and crest. This short-term retrospective investigation suggests that the BAOSFE can be a successful procedure with a wide variety of implant types and grafting procedures.

This is a summary report from An Evidence-Based Treatment Approach: Successful Regenerative Outcomes, Task Force 4, Translating Clinical Outcomes to Patient Value. It represents recommendations for translating the clinical benefits of regenerative therapies to value that the patient can understand and accept. A review of the evidence on translating clinical outcomes to patient value was presented to the task force for discussion. Then outcome criteria established by other task forces on clinical applications of regenerative therapy were used to evaluate the evidence. Published literature related to many different areas, such as clinician-patient communication, patient behavior, the role of other dental professionals, and organization of the practice and its processes, was included in this review. Outcomes charts and decision-making trees were developed to provide a framework for the recommendations of the task force. The ultimate objectives of this task force were to help the practitioner to clearly perceive the benefits that regeneration can provide to patients and to help the clinician to present the facts in a manner that will increase patients' acceptance of the recommended treatment.

A number of controversies have arisen concerning the use of guided tissue regeneration in conjunction with implant fixtures. Three of these are the effect on the regenerative result of material exposure, the type of grafting material used, and whether the fixture is placed in an extraction socket or edentulous ridge. This study examines these issues in 237 consecutive sites treated with guided tissue regeneration.

Two cases are presented to illustrate a technique for the use of the principles of guided tissue regeneration for root coverage and gingival augmentation in humans. The paper discusses the advantages of GTR over a variety of conventional root coverage techniques.

Placement of implant fixtures in an ideal position for restoration is not often possible using standard protocol, because most patients lack sufficient bone in the alveolar process. To facilitate ideal restorative placement of implant fixtures, principles of guided tissue regeneration can be used to provide adequate bone and prevent dehiscence and fenestration of the implant. Four cases of such treatment are presented.
