Abstract
Purpose
Compare the clinical stability and efficacy of locking with standard miniplates in the osteosynthesis of anterior mandibular fractures using bite force recordings and other clinical parameters.
Materials and Methods
A prospective randomized double blinded clinical trial was carried out in patients from various hospitals of Hassan. Patients were randomly divided into 2 groups of locking (test) and standard (control) miniplates osteosynthesis. The bite force measurements were performed preoperatively and postoperatively at weekly intervals for 6 weeks using a bite force recorder. As a secondary outcome, the patients also were assessed for other clinical parameters that might interfere with successful osteosynthesis at the fracture site. An appropriate statistical test for the intra and inter group measurements was carried out.
Results
48 male patients of 28±12.3years met the inclusion criteria, with 24 patients in each group. A statistically significant difference (p<0.05) was found in the incisor bite force between the two groups with values in locking exceeding those in standard at the 2nd and 5th postoperative weeks. Duration of surgery was also less in locking group (p=0.015). No significant difference was found in other clinical parameters.
Conclusions
Bite force had statistically increased at progressive follow-up visits compared with the pre operative recording in the locking group. Bite force recordings of the patients treated using locking plates were higher and statistically significant than those of the standard miniplates at the incisor region at 2nd and the 5th postoperative weeks. The clinical outcome of both miniplate systems in the present study were similar however following advantages with the use of locking miniplates can be highlighted:
