Abstract

OBJECTIVE:

In this study we report on finite element calculation to verify the mechanical stability induced by the new geometry of a novel condylar process plate. We report our clinical experiences in the treatment of condylar process fractures using the novel plate. The plate has been designed according to finite element calculations in order to optimize mechanical stability and stiffness. The potential influence of this plate on the postoperative complication rate was assessed.

STUDY DESIGN:

Thirty-five mandibular condylar process fractures in 30 patients (20 male, 10 female, age: 34.3 +/- 11.5 years) were treated with the Modus condylar process plates (Medartis, Basle, Switzerland) and are included in this study. The time periods for postoperative follow-ups were 6 weeks and 6 months.

RESULTS:

No plate fractures occurred and there was no injury to the facial nerve. In one patient a screw loosening was observed. Two patients showed inadequate reduction without functional impairment.

CONCLUSION:

The newly developed condylar process plate proved to provide sufficient mechanical stiffness to avoid plate fractures. The postoperative complication rate can be reduced significantly. Statistical comparison to other osteosynthesis methods of the condylar process was performed and showed significant differences (single miniplates: P = .006 and minidynamic compression plates: P = .055). We conclude that a single Modus condylar process plate shows results comparable to 2 miniplates.
