Introduction: Mandibular angle fracture is common in road traffic accidents. This study was conducted to compare 3D miniplate system with 2D plates for treatment of mandibular angle fractures. Materials and Methods: The study was conducted on 120 patients with mandibular angle fracture of both genders. After selecting patients, patients were divided into 2 groups of 60 each. In group I, patients were treated with 3D, 2.0-mm titanium plates, and in group II, patients were treated with 2D, 2.0-mm titanium miniplate in mandibular angle fracture. Patients were evaluated regularly after 1, 3, and 6 months for outcome of treatment. Results: In group I, males were 22 and females were 38. In group II, males were 40 and females were 20. Right angle fracture was seen in 32 patients in group I and 26 in group II. Left angle fracture was seen in 24 in group I and 28 in group II. Right angle and left parasymphysis fracture was seen in 3 in group I and 4 in group II. Left angle and right parasymphysis fracture was seen in 1 in group I and 2 in group II. [Table 3], [Graph 1] shows that in group I, after 1 month sensory deficit was present in 5 patients and in group II in 12 patients. After 3 months, there were no patients with sensory deficit in group I and 2 in group II. Preoperatively in group I, mouth opening was 24 mm and in group II patients was 25.80 mm, which increased to 31.20 mm in group I and 28.20 mm in group II at 1 month, 32 mm in group I and 30 mm in group II at 3 months, and 37.20 and 32.12 mm in groups I and II, respectively, at 6 months. The difference was significant (P < 0.05). Conclusion: 3D miniplate system is reliable and effective treatment modality for mandibular angle fractures as compared with traditional 2D miniplates.[INLINE:1]
