摘要
目的 探索不对称咬合特点与颞下颌关节紊乱病之间的联系.方法 随机收集92例18~35岁以美观问题为主诉的无颞下颌关节紊乱病(Temporomandibular disorders,TMD)症状的正畸科患者和111名以TMD症状为主诉的TMD患者,取研究模,记录以下5项咬合对称性指标:磨牙关系,尖牙关系,前牙覆(殆)覆盖关系,后牙水平向关系和整体咬合关系,对称者记为o,不对称者记为1.运用Logistic回归方法分析、比较两组的差异.结果 磨牙关系不对称(P=0.001,OR=3.038)和前牙覆骀覆盖关系不对称(P=0.029,OR=0.338)进入了logistic回归模型.结论 磨牙关系不对称与TMD之间存在相关关系.
Objective To explore the association between asymmetric occlusion and temporomandibular disorders.Methods 92 patients aged from 18 to 35 with chief complaint of aesthetic problems without signs of TMD and 111 patients with chief complaint of signs and symptoms of TMD were randomly collected and taken plaster casts at the initial visit.The cast were used for recording the five occlusion factors to analyze the symmetry:the first molar mesial-distal relationship,canine mesial-distal relationship,anterior overjet and overbite relationship,posterior horizontal relationship and overall occlusion relationship.The weight of the factors was recorded as 0 if symmetric,and as 1 if asymmetric.Logistics regression model were used for analyzing the different between two groups.Results Asymmetrical first molar mesial-distal relationship (P=0.001,OR=3.038) and asymmetrical anterior overjet and overbite relationship (P=0.029,OR =0.338) entered into the logistic regression model.Conclusions Correlation exists between the asymmetry of molar relationship and TMD.
