Reconstruction of internal orbital wall fracture with iliac crest free bone graft: clinical, computed tomography, and magnetic resonance imaging follow-up study.

Background: The purpose of this study was to clinically and radiologically assess the outcome of internal orbital reconstruction with an iliac bone graft.

Methods: Twenty-four consecutive patients with unilateral orbital wall fractures were enrolled in this prospective study. A medial cortical wall from the anterior ilium was used for reconstruction.

Failed dental implants - clinical, radiological and bacteriological findings in 17 patients.

Aim: The aim of this study was to evaluate the reasons for implant failure in two Oral and Maxillofacial Units in Helsinki. Seventeen patients, who lost 30 implants were included in this study.

Material And Methods: The patients and implants were studied clinically, radiologically and microbiologically.

The use of bioabsorbable osteofixation devices in craniomaxillofacial surgery.

Because of problems associated with the conventional osteofixation devices used in craniomaxillofacial surgery, bioabsorbable devices have presented an appealing alternative. Devices made of the polymers polyglycolide (PGA) and polylactide (PLA) and their copolymers (PLGA and PLDLA) are currently the most commonly used. Strong implants can be manufactured from these polymers with a self-reinforcing technique and used in the treatment of fractures and osteotomies.
