Implant survival in mandibles of irradiated oral cancer patients.

Objective: The aim of this study was to analyze long-term implant survival in the mandible after radiotherapy and radical surgery in oral cancer patients.

Study Design: Between 1990 and 2003, 71 patients (15 females, 56 males; average age 57.8 years, range 16-84.

Biodegradable fixation of mandibular fractures in children: stability and early results.

Objective: The aim of this study was to assess the safety and efficiency of biodegradable self-reinforced (SR-PLDLA) bone plates and screws in open reduction and internal fixation of mandible fractures in children.

Study Design: Thirteen patients (5 female, 8 male; mean age 12 years, range 5-16 years) were operated on various fractures of the mandible (2 symphyseal, 6 parasymphyseal, 4 body, 3 angle, 1 ramus, 2 condylar fractures). The mean follow-up time was 26.

Stability of biodegradable implants in treatment of mandibular fractures.

Background: Biodegradable implants have not been used on a large scale for internal fixation of mandibular fractures because of presumed inferior mechanical properties. This prospective clinical trial was designed to elucidate the stability and biocompatibility of self-reinforced poly-L/D-lactide plates and screws used to stabilize a variety of mandible fractures by open reduction and internal fixation.

Methods: Sixty-six consecutive patients (22 female, 44 male; mean age, 23.

Long-term implant survival in the grafted maxilla: results of a 12-year retrospective study.

Objective: The aim of this study was to determine the long-term outcome of implant insertion in the augmented severely atrophied maxilla.

Study Design: Three hundred and twenty-four implants were inserted in 35 patients (eight males, 27 females, average age 57.6 years) in extremely atrophied maxillae after osteotomy and interposition of iliac crest bone.
