Background: Condylar fractures account for one third of all mandibular fractures being in the range of 17.5–52%1, 2 of all mandibular fractures. The main goal in the treatment of condylar fractures is to predictably restore pre-injury anatomical form, with associated aesthetics and function. Aim: The aim of this study is to assess the efficacy and stability of single 3-D trapezoidal condylar plate and compare it with 2.0mm conventional miniplates in the Open Reduction and Internal Fixation of mandibular sub-condylar fractures. Methods: This study was conducted on 20 patients with subcondylar fracture.10 patients were allotted by random sampling in each Group. 3-D trapezoidal condylar plates were used in Group A and 2.0mm conventional minplates were used in Group B. The mini retromandibular surgical approach was common to both the groups. Function and stability was assessed post operatively at 1st, 3rd and 6th month respectively. Results: Intergroup analysis showed no statistically significant difference in results with respect to function and the stability of the fractured fragments. Conclusion: 3D trapezoidal condylar plates are more stable and structurally more efficient in reducing the torque forces leading to better osteosynthesis.
