目的:观察和分析牙列咬合特征对颞下颌关节紊乱综合征的影响因素。方法:本院2015年1月到2016年1月期间收治口腔科病人130例,按有无颞下颌关节紊乱综合征分为患者组(90例)和正常组(40例),现根据RDC-TMD轴1诊断标准进行颞下颌关节检查,取两组牙列模型分别进行spee曲线,前牙覆盖,后牙覆盖等进行测量。结果:运用SPSS13.0软件分析,前牙覆盖对颞下颌关节紊乱综合征有影响(p<0.05),后牙覆盖对颞下颌关节紊乱综合征无影响(p>0.05),颞下颌关节出现杂音且同侧spee曲线明显减小,具有统计学意义(p<0.05)。结论:牙列咬合特征(spee曲线,前牙覆盖)对颞下颌关节紊乱综合征有影响,后牙覆盖对颞下颌关节紊乱综合征无影响。
Objective: To observe and analyze the influencing factors of occlusion of temporomandibular joint syndrome. Methods: From January 2015 to January 2016, 130 patients with stomatology were admitted to our hospital. Patients were divided into the patient group (90 cases) and the normal group (40 cases) according to the presence or absence of temporomandibular joint syndrome. According to RDC- TMD axis 1 diagnostic criteria for temporomandibular joint examination, take two sets of dentition model were spee curve, anterior tooth coverage, posterior teeth coverage were measured. Results: SPSS 13.0 software analysis showed that the anterior tooth coverage affected the TMJ disorders (p <0.05), and the posterior teeth coverage had no effect on the TMJ disorders (p> 0.05). The temporomandibular joint had noises And ipsilateral spee curve was significantly reduced, with statistical significance (p <0.05). CONCLUSIONS: The occlusal characteristics of the dentition (spee curve, anterior teeth covering) have an impact on the TMJ disorders, and the posterior teeth coverage has no effect on the TMJ disorders.
