Introduction:
Mandibular angle fracture (MAF) is the second most common site of all fractures of the mandible with the highest complication rate. Management of MAF has evolved in the past four decades. The purpose of the prospective study was to compare the efficacy of new design titanium miniplate (NDM) with conventional titanium miniplate (CTM) in the treatment of MAF.
Objectives:
Mouth opening, occlusion, bite force measurement, and radiographs compared preoperatively and first week, first month and third month postoperatively.
Materials And Method:
Fourteen patients diagnosed with MAF were randomly divided into two groups: Group A (seven patients) was treated with NDM and Group B (seven patients) with CTM. Patients were assessed preoperatively and postoperatively at an interval of one week, one month and three months.
Results:
Repeated measures ANOVA and Post hoc Tukey test showed a significant increase in bite force and mouth opening for both groups in first and third postoperative months. Unpaired t-test showed slightly better mouth opening in Group B and slightly higher bite force in Group A.
Discussion:
Both miniplates fulfilled all the study objectives and equally satisfactory healing was seen at the end of third month. NDM offers better stability, rigidity, and anatomic reduction of the fracture with a drawback of difficulty in adaptation and increased operative timing compared to CTM. Hence, we would like to conclude that both miniplates are equally efficient in the treatment of non-comminuted angle fractures with the NDM having upper hand in stability.
