Mandibular angle fractures (MAFs) are treated in a variety of ways; however, the standard therapy is still up for debate. Despite the fact that many studies have generated evidence for the appropriate biomechanical stability of 3-D miniplates, there is an insufficient amount of data on the treatment of mandibular angle fractures with these plates. A comparative study was conducted at The Department of Oral and Maxillofacial Surgery, Pakistan Institute of Medical Sciences (PIMS), Islamabad. Patients were randomly divided into two groups of 52 patients each. Patients in group A were treated with 3-D miniplate placement on the lateral cortex following the principle of 3-D fixation proposed by Farmand and Dupoirieux, whereas patients included in group B were treated using 2-D conventional miniplate, placed according to Champy’s line of ideal osteosynthesis. A single surgical team performed the procedure. On the first and seventh post-operative days, the first month, and then the third month after surgery, regular evaluations were conducted. Assessment regarding Post Open Reduction and Internal Fixation (ORIF) occlusion was performed with the help of measuring tools. On the first day post-operative follow-up, 41 (78.8%) patients in group A and 31 (59.6%) patients in group B had satisfactory occlusion. The seventh day post-operative follow-up showed that 43 (82.7%) patients in group A and 41 (78.8%) patients in group B had satisfactory occlusion (p > 0.05). In both treatment groups, the first and third month follow-up evaluations revealed optimal occlusion. In comparison to conventional 2-D miniplate, the 3-D miniplate system produced better results and can be recommended as a better option for the management of mandibular angle fractures.

Background:To determine the correlation between impacted M3 and mandibular angle and condylar fractures considering the hypothesis that the presence of M3s increases the risk of mandibular angle and simultaneously decreases the risk of condylar fracture and vice versa.. Methods: In this cohort study seventy-five patients having ninety-two hemi-mandibles with fracture of condylar process or angle were included. Status of third molar on the fractured side of mandible was determined. Based on status of mandibular third molars patients were broadly classified into two groups i.e. erupted and impacted. Results:Among the total 92 hemi-mandibles that were fractured, 56.5% had angle fractures while 43.5% had condylar fractures. Out of total 48 hemi-mandibles with impacted third molars, mandibular angle was fractured in 72.92%. While among 44 hemi-mandibles having erupted third molars, 61.36% had condylar fractures. Conclusion: Mandibular angle fractures more readily as the result of facial trauma in the presence of an impacted M3,especially with Class B depth and class 2 ramus position. Absence of an impacted mandibular third molar increases the risk of condylar fractures while concomitantly decreasing the risk of mandibular angle fracture.
