Success rates of osseointegration for implants placed under sterile versus clean conditions.

A retrospective analysis was done comparing the success rate of osseointegration at stage 2 of implants placed under "sterile" versus "clean" conditions. "Sterile" surgery took place in an operating room setting with strict sterile protocol. "Clean" surgery took place in a clinic setting with the critical factor that nothing touched the surface of the implant until it contacted the prepared bone site. A total of 273 implants in 61 cases were placed under sterile conditions with a fixture success rate of 98.9% and a case success rate of 95.1%; 113 implants were placed under clean conditions in 31 cases with a fixture and case success rate of 98.2% and 93.5%, respectively as judged clinically at stage 2. The difference in the success rates was not statistically significant. The results of this analysis indicate that implant surgery can be performed under both "sterile" and "clean" conditions to achieve the same high rate of clinical osseointegration.

The effect of crestal versus mucobuccal incisions on the success rate of implant osseointegration.

A retrospective analysis compared the success rate of osseointegration of Nobelpharma implants at stage 2 surgery. The implants had been placed using either a mucobuccal fold incision or a crestal incision. A total of 386 implants was placed in 92 patients; 265 implants were placed in 60 patients using a mucobuccal fold incision, with a success rate of 98.8%, and 121 implants were placed in 32 patients using a crestal incision, with a success rate of 98.3%. Implants can be placed using either a mucobuccal fold incision or a crestal incision to achieve predictable success.

Role of industry representatives in providing assistance to certified diabetes educators.

OBJECTIVE: As diabetes educators have become more frequently involved in decisions regarding medications, equipment, and supplies, industry representatives have increasingly provided various types of assistance. The major objectives of this survey were to determine 1) the types of assistance being provided to certified diabetes educators (CDEs) by industry representatives, 2) whether product recommendations are based on assistance provided, and 3) the types of assistance that CDEs consider appropriate. RESEARCH DESIGN AND METHODS: We developed the survey instrument and it was mailed to every fifth person listed in the 1989 directory of CDEs. Three hundred twenty-five (51%) of the active surveys were returned. RESULTS: Those responding indicated that 1) the types of support provided most frequently by industry representatives include instructional materials, samples, supplies, and equipment for patient care and education; 2) the number of types of support provided is directly related to the number of industry representatives seen on a regular basis and the frequency of interaction; 3) 22% of the educators state that they make product recommendations based on support provided; and 4) the role of the industry reps should be to continue support for patient care and education, to provide more support for public and professional education, and to minimize support for personal items, e.g., gifts or meals. CONCLUSIONS: The survey indicates that CDEs are receiving many types of assistance from industry representatives and that they prefer that such assistance be targeted toward patient and professional education.

Modified roll technique for localized alveolar ridge augmentation.

A modification of Abram's roll technique is described. A "trap-door" approach is used to reflect and preserve the epithelium that overlies the connective tissue pedicle; the epithelial pedicle is used to cover the donor site. Two case reports illustrate the technique.
