“…Consistent with other studies, our results confirmed an increased risk of angle fractures when M3s were present as well as a variable risk for angle fractures depending on M3 position [1,2,4,[8][9][10][11]. We found higher incidence of angle fracture in the age group B (19-39 years) which is similar to Halmos et al [12] study.…”

“…Fractures of the mandibular angle represent the largest percentage of mandibular fractures in many studies [1,2]. Approximately 25-33 % of all mandibular fractures are angle fractures and several proposed reasons include the presence of third molars; a thinner cross-sectional area than the tooth-bearing region and also biomechanically the angle can be considered a ''lever'' area.…”

Introduction This study was designed to evaluate the influence of eruption status of mandibular third molars on the location of mandibular angle fracture. We also aimed to evaluate the incidence of damage to mandibular third molar teeth (M3) and its roots. Materials and Methods Medical records and panoramic radiographs of 142 patient cohorts with mandibular angle fractures with third molars present were retrospectively reviewed.Results Revealed that incidence of angle fracture were high in patients with fully erupted M3 when compared to unerupted group. Out of 142 patients, 108 fractures were found involving the M3 socket and 14.1 % had damage to M3. Conclusion The presence of erupted mandibular third molar increases the chances of angle fracture when compared to impacted M3. Involvement of the M3 socket often resulted in increased operative time and complexity of the surgical procedure with possible removal of the damaged M3.

“…Studies in animals and humans have confirmed that the presence of third molars is associated with an increased risk of mandibular angle fractures. 1,4,10 Many authors have concluded that the severity of the force necessary to produce an angle fracture is substantially less when a third molar is present compared with when absent. 1 According to a theory, the third molars would weaken the angle by reducing the total available bone mass in the region.…”

Aims: This retrospective study was done to evaluate the efficacy of single miniplate osteosynthesis at superior border of angle of mandible. Material and methods:In this study 50 patients were treated by single miniplate osteosynthesis according to Champy's principle. Bite force generated was used as a parameter for judging the efficacy of internal fixation. In this article we present our experience over the years in the management of the fractures of angle of mandible based on this model.Results: Most patients were of 21e30 yrs of age with unilateral angle fracture of mandible except one patient who had isolated bilateral angle fracture. The patients were treated successfully according to Champy's principle of osteosynthesis. There was a progressive improvement in the bite force generated after osteosynthesis. Conclusions:The angle of the mandible is an anatomically weak and an area susceptible to fracture. The presence of an impacted or partially erupted third molar tooth further weakens it. Angle of mandible is the most common site for fracture however, bilateral angle fracture is very rare and uncommon. Osteosynthesis according to Champy's model led to an early functional improvement as demonstrated by the bite force generated.

“…In terms of the precise reduction and fixation of mandibular fractures, difficulties are often encountered in repositioning the condylar fragments and performing accurate placement of the plates and screws (19), in addition there is the possibility of facial nerve injury (20,21), excellent reduction and stable fixation in angle fractures are easily performed because the access and visibility to the angle fractures for plating is much better. Thus it might not be appropriate to strengthen the mandibular angle region and to make the mandible more vulnerable to condylar fractures by removing the unerupted third molars because the treatment of condylar fractures is more challenging than that of angle (22,23).…”
