A comparative study of osseointegration of titanium implants in autogenous and freeze-dried bone grafts.

Purpose: This study was undertaken to compare the rate and degree of osseointegration of dental implants when placed into either autogenous corticocancellous chip or freeze-dried corticocancellous chip bone grafts.

Materials And Methods: The canine ilium was used as the model site. Thirty experimental and 15 control implants were placed in 15 dogs: autogenous versus freeze-dried corticocancellous chip bone grafts around the exposed implant surfaces.

Neurosensory recovery following the mandibular bilateral sagittal split osteotomy.

Purpose: This prospective study evaluated the neurosensory recovery pattern of the inferior alveolar nerve following the bilateral sagittal split osteotomy (BSSO).

Patients And Methods: Forty-two consecutive patients undergoing BSSO were studied using five neurosensory tests: 1) static light touch, 2) moving touch discrimination, 3) two-point discrimination, 4) nociception, and 5) thermoreception. Intraoperative assessment of inferior alveolar nerve damage was made; other variables recorded included type of fixation, age, concomitant procedures, advancement vs setback, and magnitude of the movement.
