Long-term changes in graft height after maxillary sinus floor elevation with different grafting materials: radiographic evaluation with a minimum follow-up of 4.5 years.

Objective: To compare the vertical dimensional changes with regard to graft height in a long-term follow-up in patients treated with two different grafting materials used in maxillary sinus floor elevation procedures.

Material And Methods: Twenty consecutive patients were included. One group was grafted with autogenous bone from the mandible (chin area), and the other group was augmented with a 100% beta-tricalcium phosphate (beta-TCP).

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).

The surgical management of post-traumatic malocclusion.

Facial skeleton fractures should be reduced as early as possible to restore optimal function and minimize skeletal and soft-tissue deformity. With unsatisfactory outcome from delayed treatment because of comorbidity, or despite optimal management, late reconstruction can succeed with conventional orthognathic surgical procedures. Management follows well-established principles of correcting dentofacial deformities, coordinated with orthodontic and prosthodontic support.

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.

Histomorphometry of human sinus floor augmentation using a porous beta-tricalcium phosphate: a prospective study.

Tricalcium phosphate (TCP) has been historically a well-accepted material for bone augmentation. We examined the use of a porous beta-TCP (100%) in a split mouth model for sinus floor augmentation. Five patients were treated bilaterally, receiving 1-2 mm-sized beta-TCP particles (Cerasorb) on one side (test side) and autologous chin bone particles on the other (control) side.

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.
