説明

Purpose: In our previous study, we observed variations of occlusal plane inclination in adult patients, and investigated the factors affecting changes in occlusal plane inclination with aging. From our results, it was suggested that the mandibular morphology change and loss of teeth with aging, influence occlusal plane inclination. However, the investigations of the parameters regarding dentition characteristics were insufficient. In this current study, we add the dentition parameters and create a linear regression model to estimate the alteration of the occlusal plane in adults.<br>Subjects and Methods: Subjects were 143 patients consecutively recruited, and were divided into 2 groups without/with missing teeth (no-MT group / MT group). Cephalometric images were taken. Our inquiry points included 13 variables regarding to cranio-mandibular morphology and dentition. We investigated the differences in age and the anatomical variables between no-MT group and MT group, the linear relationships between variables, and linear regression.<br>Results: In the 8 variables, there were statistically significant differences between both groups. Camper-occlusal plane angle (COA) was correlated with all variables. The variables Number of missing molar teeth (MolarMT), Mandibular plane angle (MPA), and the inclination of upper and lower incisal axis to Camper plane (CamU1, CamL1), explained 69.8% of the variance in COA (p < .001).<br>Conclusion: From our results, it was suggested that evaluation of occlusal plane inclination is important in adult patients with loss of occlusal posterior support. For these types of patients, we recommend evaluating the occlusal plane using Camper's plane in the clinic.
