Anatomical and surgical findings and complications in 100 consecutive maxillary sinus floor elevation procedures.

Purpose: To investigate the prevalence of anatomical and surgical findings and complications in maxillary sinus floor elevation surgery, and to describe the clinical implications.

Patients And Methods: One hundred consecutive patients scheduled for maxillary sinus floor elevation were included. The patients consisted of 36 men (36%) and 64 women (64%), with a mean age of 50 years (range, 17 to 73 years).

Maxillary sinus floor augmentation using a beta-tricalcium phosphate (Cerasorb) alone compared to autogenous bone grafts.

Purpose: A prospective human clinical study was conducted to determine the clinical and histologic bone formation ability of 2 graft materials, a beta-tricalcium phosphate (Cerasorb; Curasan, Kleinostheim, Germany) and autogenous chin bone, in maxillary sinus floor elevation surgery.

Materials And Methods: Ten healthy patients underwent a bilateral (n = 6) or unilateral (n = 4) maxillary sinus floor elevation procedure under local anesthesia. In each case, residual posterior maxillary bone height was between 4 and 8 mm.

Fractures of the iliac crest after split-thickness bone grafting for preprosthetic surgery: report of 3 cases and review of the literature.

Purpose: In this study fractures of the iliac crest after split-thickness bone grafting in a patient population treated for preprosthetic reasons were evaluated.

Patients And Methods: In a retrospective patient population of 146 patients, during a 5-year period (1998 to 2002), 3 avulsion fractures of the iliac crest were noticed. All fractures were postsurgical, occurring as late fractures.
