Bonwill's triangle is an imaginary equilateral triangle formed when the centers of two condyles and each condyle with the medial mandibular incisal midpoint are joined. The dimensions of the tooth, with other bones of cranium, and the entire anatomical structure of body are in persistent association with the distance of the borders of the triangle. It can be used to study articulation of the mandible, complete dentures, and dental occlusion and can be related when treating mandibular fractures. The aim is to analyze the variations in the length of Bonwill's triangle in dry human mandibles and its dental implications. Forty dry human mandibles were taken to carry out this study. Distances between the center of the right condylar process to the inner medial mandibular incisal midpoint (A), the distance between the center of the left condylar process to the inner medial mandibular incisal midpoint (B), and the distance between the centers of right and left condylar process of mandible (C) were measured with the aid of digital vernier caliper. The statistics was evaluated and observed using the statistical analysis software SPSS (Version 20.0) and the mean and standard deviation was calculated. The mean length between right condyle center and medial mandibular incisal midpoint is 97.76 mm, between left condyle center and medial mandibular incisal midpoint is 98.55 mm, and between the right and left condyle centers is 97.39 mm. The values are almost equal to 4 inches. The mandibular measurements serve as an important factor for many clinical conditions especially related to dentistry. The results of this study can be of great significance when treating mandibular fractures and defects.
邦威尔三角是一个假想的等边三角形，由两个髁突的中心与每个髁突和下颌中切牙内侧中点相连而成。牙齿的尺寸、颅骨的其他骨骼以及身体的整个解剖结构与该三角形边界的距离始终相关。它可用于研究下颌关节、全口义齿和牙合关系，在治疗下颌骨折时也可作为参考。目的是分析干燥人下颌骨中邦威尔三角长度的变化及其对牙科的影响。本研究采用了40个干燥人下颌骨。借助数字游标卡尺测量右侧髁突中心至下颌中切牙内侧中点的距离（A）、左侧髁突中心至下颌中切牙内侧中点的距离（B）以及下颌左右髁突中心之间的距离（C）。使用统计分析软件SPSS（版本20.0）对数据进行评估和观察，并计算平均值和标准差。右侧髁突中心与下颌中切牙内侧中点之间的平均长度为97.76毫米，左侧髁突中心与下颌中切牙内侧中点之间的平均长度为98.55毫米，左右髁突中心之间的平均长度为97.39毫米。这些值几乎等于4英寸。下颌测量是许多临床情况尤其是与牙科相关情况的重要因素。本研究结果在治疗下颌骨折和缺损时可能具有重要意义。
