![]() ![]() In this case the fracture of his mandibular angle was oblique (unfavorable), complete and composed. The third patient was a 36-year-old Caucasian man who had undergone surgical removal of a 3.8, vertical variety, class II-C third molar 25 days before the observation. The fracture, which occurred during mastication, was studied by computed tomography that showed reparative tissue in the fracture site. He had undergone surgical removal of a 3.8, mesioangular variety, class II-B third molar 22 days before his admission. The second patient was a 32-year-old Caucasian man. The fracture of his left mandibular angle, complete and composed, occurred during chewing. The first patient was a 27-year-old Caucasian man who had undergone surgical removal of a 3.8, mesioangular variety, class II-C third molar 20 days before admission to our clinic. We describe three new cases of pathological (late) fracture of the mandibular angle after third molar surgery. There are 94 cases reported in the literature cases associated with osseous pathologies such as osteomyelitis or any local and systemic diseases that may compromise mandibular bone strength have not been included. Pathological (late) fracture of the mandibular angle after third molar surgery is very rare (0.005% of third molar removals). The remote possible risk of the late fracture shown in our patients indicates the need for no special precautions. In patients, fully dentate or with 1 or 2 teeth missing and older than 25 years who have no jawbone atrophy and no systemic problems that may impair bone strength, mastication seems not to affect late mandibular fracture after surgical removal of impacted M3s associated with no gross pathology. 427), class highest portion of the M3 crown (P =. ![]() ![]() 552), class horizontal space available (P =. In no patient group was there a statistically significant difference in relation to gender (P =. All patients completed the follow-up period, and most of the R group patients had normal eating habits 10 to 14 days after surgery. In no patient group was there a late mandibular fracture recorded. 05 was considered statistically significant. Patients were followed up for 2 months, and data concerning patients' age and gender tooth position, angulation, and depth date and site of surgery and occurrence of late mandibular fracture were recorded and statistically analyzed. In the R group, patients were given no such education or emphasis. In the NR group, patients were postoperatively educated in the possibility of mandibular fracture and were given an emphasis on the necessity of limiting mastication to a soft diet for 4 weeks. They were operated on under local anesthesia using a standard technique and randomly assigned into 2 groups for nonroutine (NR group) and routine (R group) postoperative instructions. This study was undertaken with the null hypothesis that in patients, fully denate or with 1 or 2 teeth missing and older than 25 years, mastication does not affect late mandibular fracture after surgical removal of impacted third molars (M3s) associated with no gross pathology.įive hundred sixty patients, fully dentate or with 1 or 2 teeth missing and older than 25 years who had no gross pathology associated with their impacted lower M3s, were recruited in this study. ![]()
