This study aimed to analyze the relationship of the occlusal support together with the lower third molars to the mandibular fractures of the angle and condyle among patients in our medical institutions. This was a retrospective study that reviewed the medical records and radiographs of all patients treated for mandibular fractures from 2015 to 2019. The data collected by using picture archiving and communicating system. Only records with mandibular angle or condyle fractures were included. The dependent variable was the presence of the fractures of the mandibular angle or condyle. The independent variables were epidemiological data, third molar characteristics, existence or absence of occlusal support. The data was analyzed through Univariate logistic regression and multivariate logistic regression. From a total of 187 mandibular fractures, 44 presented mandibular angle fracture and 29 shown condyle fractures. The average age was 40.34 ± 13.47 years. The absence of occlusal support increased the chance of condyle fractures by 5.1 times (95% CI 1.61-17.29). The lack of occlusal support is more associated with condyle fractures than the presence of occlusal support, regardless of third molar presence and characteristics and other variables evaluated.
本研究旨在分析咬合支持与下颌第三磨牙与我院下颌角和髁突骨折患者的关系。这是一项回顾性研究，分析了 2015 年至 2019 年所有下颌骨骨折患者的病历和 X 光片。使用图像存档和通信系统收集数据。仅包括下颌角或髁突骨折的记录。因变量是下颌角或髁突骨折的存在。自变量是流行病学数据、第三磨牙特征、咬合支持的存在与否。通过单变量逻辑回归和多变量逻辑回归分析数据。在总共 187 例下颌骨骨折中，44 例为下颌角骨折，29 例为髁突骨折。平均年龄为 40.34±13.47 岁。咬合支持的缺失使髁突骨折的几率增加了 5.1 倍（95%CI1.61-17.29）。无论是否存在第三磨牙及其特征和其他评估变量，咬合支持的缺失与髁突骨折的关系更为密切，而不是存在咬合支持。
