Abstract: Objective: The purpose of this study was to perform a dental examination of the general population, measuring tooth wear and craniofacial morphological parameters to study the effects of craniofacial structural features on tooth wear distribution. Methods: For the initial data of 103 orthodontic patients collected, the wear area of each tooth was measured on the model, and the cephalometry of the patient was subjected to head ANB, MP-FH (FMA) and FMIA, and analysis of the correlation between cephalometric data and tooth wear. Results: The wear area of the upper and lower anterior teeth was statistically different. The ANB was positively correlated with the total wear area and the average wear area of the anterior and posterior teeth. MP-FH (FMA) was negatively correlated with the ratio of the wear area of the anterior and posterior tooth; FMIA was negatively correlated with the average wear area of the posterior tooth. Conclusion: There is a certain correlation between the wear area of the tooth and the cephalometric measurement in the general population. The too steep occlusal plane can cause the posterior teeth to wear more seriously.
