Abstract: Aim this study aimed to compare clinically and radiographically the use of single locking miniplate with the 3d threadlock miniplate in the management of the isolated mandibular angle fractures. Material and methodsfourteen ptients with isolated displaced mandibular angle fractures were subdivided into two equal groups. Group 1 were treated by open reduction and internal fixation using single locking miniplate through intraoral approach. Group 2 were treated by open reduction and internal fixation using 3d threadlock miniplate through extraoral approach. Both groups were followed up clinically and radiographically for 3 months evaluating the pain, the facial edema, the occlusal disturbances, the maximal mouth opening, the sensory function, the infection at the surgical site and the bone density at the site of the fracture. The results were calculated, compared and statistically analysed to indicate the efficacy of both plate types in the treatment of displaced isolated mandibular angle fracture. Results All the clinical parameters evaluated were statistically insignificant (p value 0.05) except the facial edema as p value was 0.001, 0.001 and <0.001 along the follow up period. Radiographically the results were statistically significant at the 6th week and at the 12th week postoperatively p value was 0.001 and <0.001 respectively. Conclusion both plating systems were suitable for the management of isolated mandibular angle fractures with small number of major complications, but the single locking miniplate was econocomically better and giving almost the same result as the 3d threadlock miniplate did.
