[Load resistance of mandibular angle fracturs treated with a miniplate osteosynthesis].

AIMS
The aim of this study was to evaluate the load resistance of mandibular angle fractures treated with a miniplate osteosynthesis according to Champy.


MATERIAL AND METHODS
We evaluated 22 completely dentate patients with fractures of the angle in addition to 15 controls. An electric test procedure for the determination of the load resistance between the incisors, canines and molars was carried out 1-6 weeks after treatment.


RESULTS
At 1 week postoperatively 90 N was registered between the molars while after 6 weeks this was 148 N. This revealed only 31% and 58% of the maximal vertical load found in the controls, respectively.


CONCLUSION
The minipate osteosynthesis according to Champy offers a secure method in the treatment of mandibular angle fractures with sufficient stability. Maximum voluntary bite forces were not registered during the time of healing.
