Purpose: The aim of this study is to compare the postoperative complications after fixation of mandibular angle fractures with 2 noncompression miniplates, in which a single plate is fixed onto the superior border of the mandible and the other plate to the lateral aspect of the mandible, with the standard technique of a single noncompression miniplate fixed onto the superior border of the mandible.
Materials And Methods: We randomly divided 54 patients with unilateral mandibular angle fractures into 2 groups, with 27 in each group. Randomization was done with lots in closed envelopes. Group I patients were treated with a single noncompression miniplate fixed at the superior border as suggested by Champy et al through an intraoral approach. Group II patients were treated with 2 noncompression miniplates in which 1 plate was fixed in a manner similar to that in group I and the other plate was fixed to the lateral aspect of the angle of the mandible with combined intraoral and transcutaneous access through a trocar and cannula. The patients were assessed for malocclusion, infection, wound dehiscence, and plate exposure. The data were analyzed statistically with the chi(2) test, and statistical analysis was performed with SPSS statistical software for Windows, version 8.0 (SPSS, Chicago, IL).
Results: Group I comprised 21 men and 6 women with a mean age of 32.4 years (range, 18-43 years). Group II comprised 23 men and 4 women with a mean age of 29.6 years (range, 21-49 years). No patients complained of malocclusion in either group. Wound dehiscence occurred in 3 patients (11.1%) in group I and 2 patients (7.4%) in group II, which was not statistically significant (chi(2) = 0.0, P > .99). Infection occurred in 1 patient (3.7%) in group I and 2 patients (7.4%) in group II, which was not statistically significant (chi(2) = 0.0, P > .99). One patient from both the groups required plate removal. Scar developed at the transcutaneous incision site in 5 patients (18.5%) in group II.
Conclusion: The use of 2 noncompression miniplates for treating noncomminuted fractures of the mandibular angle does not seem to have any advantage over the use of a single plate.

The anatomical characteristics and the cortico-cancellous nature of bone disrupted by the presence of teeth make the mandible more vulnerable to fractures during traumatic injuries of the face. Fractures of the angle region constitute about 30% of mandibular fractures due to the change in dentate bone to the lateral flare of ramus, change in grain pattern of the bone, and presence of third molars all weakening the region making it fragile and thus fracture. Several studies corroborated the effectiveness of Champy's technique as to have the lowest complication rate when compared to the other techniques.

Purpose: To evaluate postoperative masticatory efficacy of a new design non-compression titanium miniplate compared to conventional non-compression titanium miniplate on the basis of bite force for treatment of mandibular angle fractures.
Methodology: The prospective study included 20 patients with mandibular angle fractures randomly categorized into 2 groups: Group I, fixation of angle fractures by conventional miniplates, and Group II, fixation of angle fractures by new design miniplates. Evaluation was done for clinical outcome, primarily bite force; radiological outcome; and associated postoperative morbidities at different time intervals.

Aim: To compare the postoperative complications of fixing Mandibular angle fractures with two non-compression mini plates, on the superior and lateral the aspects of the mandible, to the standard technique of using a single non-compression miniplate on the superior border.
Methodology: Fifty patients with MAF were divided equally into two groups. Patients in Group 1 were secured with two mini plates at the lateral and superior border of the MA using an extraoral approach; for patients in Group 2 a single non-compression miniplate was used via an intraoral extended third molar approach as described by Champy .

The aim of the study was to conduct a randomized clinical trial comparing the efficacy of standard non-compression miniplate and 3-dimensional (3D) titanium plate in the open reduction internal fixation (ORIF) of the mandibular condylar fractures. Patients who underwent open reduction of mandibular condylar fracture were recruited for the study. The patients satisfying the inclusion criteria were randomly assigned to two groups in a 1:1 ratio.
