Introduction: Dysfunction of temporomandibular joint is present in 70-75% of orthodontic patients. Evaluation of TMJ and detailed characteristics of its elements with additional methods of examination in children and adults is necessary for clinical definition of proposed disturbances of the structure and functions of the joint. The aim of the investigation is to study morphological symmetry of TMJ in patients with dentofacial abnormalities and with dentofacial abnormalities complicated by secondary edentulism.
Materials and Methods: 57 patients were involved in the examination. Based on gender principle patients' distribution was almost equal: there were 30 women and 27 men. Cone-beam computerized tomography (CBCT) Galileos (SIRONA DENTAL, Germany) was used to all patients.
Results: It was done analysis of parameters (height and length) of right and left heads (condyles) of temporomandibular joint in both groups. Asymmetry of parameters of heads' length in saggital area in patients of the second group was defined. It was proved statistically (left 10,38±0,76, right 8,16±0,78).
Conclusions: Increase of asymmetry of length of heads of TMJ in saggital area with age was determined. It can be explained by complication of dentofacial abnormalities and the presence of secondary edentulism. Depending on bite type length of condyle, especially at prognathism (in saggital) area peculiar clinical problems with TMJ can be present due to asymmetry of condyles. The size of joint gaps of TMJ due to the presence of dentofacial abnormalities with age demonstrates compensatory ability and saves its.
引言：70 - 75%的正畸患者存在颞下颌关节功能障碍。对于关节结构和功能拟议紊乱的临床定义而言，采用额外检查方法评估儿童和成人的颞下颌关节及其组成部分的详细特征很有必要。本研究的目的是探讨牙颌面异常患者以及并发继发性牙列缺失的牙颌面异常患者颞下颌关节的形态对称性。
材料与方法：57例患者参与检查。基于性别原则，患者分布大致相等：女性30例，男性27例。所有患者均使用德国西诺德牙科公司的伽利略锥形束计算机断层扫描（CBCT）。
结果：对两组患者颞下颌关节左右头部（髁突）的参数（高度和长度）进行了分析。确定了第二组患者矢状面头部长度参数的不对称性。经统计学验证（左侧10.38±0.76，右侧8.16±0.78）。
结论：确定了颞下颌关节头部矢状面长度不对称性随年龄增加。这可以用牙颌面异常的并发症和继发性牙列缺失的存在来解释。根据咬合类型，髁突长度，尤其是在凸颌（矢状面）区域，由于髁突不对称，颞下颌关节可能出现特殊的临床问题。由于牙颌面异常的存在，颞下颌关节间隙大小随年龄显示出补偿能力并得以保留。
