Comparison of single versus two non-compression miniplates in the management of unfavourable angle fracture of the mandible: a prospective randomized clinical study.

PURPOSE: The purpose of this study was to compare the efficacy of single versus two non-compression miniplates in the management of unfavourable angle fracture of mandible.

MATERIALS AND

METHODS

A total of 28 patients who required open reduction of mandibular angle fracture were included in the study. The patients were randomly divided into two groups. Group I comprised of patients treated with two miniplates and those in group II were treated with single non-compression miniplate. The parameters of assessment were malocclusion, surgical site infection, need for implant removal, duration of surgery, inter-incisal mouth opening and cost of implants used, in both the groups. Statistical analysis was carried out to compare all the parameters.

RESULTS

Out of 14 patients in group II, inadequate reduction was noticed in three patients, whereas screw loosening had occurred in two cases. Screw loosening was always associated with chronic infection. In these cases, hardware removal was deemed necessary. Plate bending was observed in two cases resulting in malocclusion and difficulty in eating. Non-union of fracture occurred in one patient treated in group II. In group I, no plate bending, screw loosening, surgical site infection, non-union or malocclusion was observed. No patient had to undergo implant removal in group I.

CONCLUSION

In the management of unfavourable mandibular angle fracture, two miniplates must be preferred over the use of single miniplate as using two miniplates results in better results with minimal complications.
