Comparison of 2 mm single locking miniplates versus 2 mm two non-locking miniplates in symphysis and parasymphysis fracture of mandible.
BACKGROUND
The purpose of this study is to compare the efficacy of single 2 mm locking miniplates versus two 2 mm non-locking (conventional) miniplates in symphysis and parasymphysis fracture of mandible.


METHODS
This present study included 40 patients of maxillofacial trauma having mandibular symphysis/parasymphysis fractures in which open reduction and internal fixation is indicated. Patients were selected according to the inclusion criteria and divided into two groups, i.e. Group 1: consisted of 20 patients, requiring open reduction and internal fixation with 2 mm two non-locking titanium plate and Group 2: consisted of 20 patients, requiring open reduction and internal fixation with 2.0 mm single ultra-locking titanium plate. Fracture was then stabilized and postoperative clinical examination was carried out on 3rd day, 1st, 2nd, 4th, and 8th week.


RESULTS
Results of this study suggested that the use of single 2.0 mm locking miniplate could be a viable option instead of using two miniplates in anterior mandibular fracture as advocated by Champy, as it provides equally good outcome along with placement of lesser implant material.


CONCLUSIONS
Single locking miniplates give the advantage of equally good stability and early restoration of function with almost similar results as seen in osteosynthesis with two miniplates. It was also found that less precision was required in plate adaptation when using single locking miniplate. This study suggests that there is not much difference in surgical outcome with the use of either single locking miniplate or two conventional miniplates in anterior mandibular region.
