文题释义:
下颌运动轨迹描记仪:是一种磁电量转换方式的描记仪,能从矢状面、额状面和水平面精确地观测下颌中切牙切点运动的轨迹,是一种快速、准确操作、简便无损伤性,不限制下颌运动的三维描记仪。
错牙合:上下颌牙齿正常接触关系的偏差。常被分为3种主要形式(Angle分类):第Ⅰ类:上下颌磨牙为正常关系,但前牙拥挤或错位;第Ⅱ类:下颌和下颌磨牙后移,面部侧面观呈凸出形;第Ⅲ类:下颌和下颌磨牙与上颌磨牙的关系为前突,反时一个或更多的下颌牙的颊尖位于相应的上颌牙牙尖的外侧。
摘要
背景:
错牙合畸形者牙列牙弓的不协调直接影响着下颌运动的发挥,甚至会造成颞下颌关节的超负荷,最终发生病变。
目的:测量各类牙合型人群的下颌运动特点。
方法:①选取符合实验标准的自愿者33人,平均年龄21.71岁,男性1人,女性32人。分为4组,正常对照组10人,安氏Ⅰ类错牙合组10人,安氏Ⅱ类错牙合组8人,安氏Ⅲ类错牙合组5人;②用描记仪测量各组下颌各运动的轨迹,以及下颌姿势位到牙尖交错位的运动轨迹;③用SPSS17.0软件进行统计学分析,得出各组人群下颌运动轨迹特点和差异。
结果与结论:①开闭口、左侧、右侧、前伸运动时,安氏Ⅱ类错牙合畸形组人群右下颌第1磨牙运动轨迹的最大距离与其他3组比较,差异有显著性意义(P < 0.05);②做快速开闭口运动时,正常对照组下颌中切牙切点运动的垂直距离与安氏Ⅰ类错牙合畸形组、安氏Ⅲ类错牙合畸形组比较差异有显著性意义(< 0.05);正常对照组最大距离与安氏Ⅰ类错牙合畸形组比较差异有显著性意义(P < 0.05);安氏Ⅱ类错牙合畸形组右下颌第1磨牙运动的垂直距离与其余3组比较差异有显著性意义(P < 0.05);正常对照组最快开口速度与安氏Ⅱ类错牙合畸形组、安氏Ⅲ类错牙合畸形组比较差异有显著性意义(P < 0.05);③各组人群息止牙合间隙不存在显著性差异。结果提示,不同牙合型人群下颌中切牙运动轨迹、下颌第1磨牙运动轨迹和运动速度不同,因而推断错牙合畸形可以影响下颌运动的方向、范围和速度。

Abstract:

BACKGROUND: Maxillofacial malformation limits the function of the mandible, produces the overload of the temporalmandibular joint leading to oral diseases.
OBJECTIVE: To measure the characteristics of mandibular movement in populations with various types of dental occlusion.
METHODS: Thirty-three volunteers (1 male and 32 females, mean age 21.71 years) meeting the inclusion criteria were enrolled from Dalian Medical University, China and divided into four groups: normal control (n=10), Angle’s class I, II, III malocclusion (n=10, 8, 5). The protrusion, lateral, opening motion trace of mandibular central incisor and the right mandibular first molar, and the trace from mandibular postural position to intercuspal position were measured using the mandibular kinesiograph. The features of different occlusal patterns were analyzed using SPSS 17.0 software.
RESULTS AND CONCLUSION: In the trace of protrusion, lateral, opening and closing motion, there were significant differences in the trace of the right mandibular first molar’s Max.Slant between Angle’s class II malocclusion group and the other three groups (P < 0.05). In the trace of open wide and close fast, there were significant differences in the trace of mandibular central incisor in vertical distances between normal control group and Angle’s class I, III malocclusion groups (P < 0.05); there were significant differences in the trace of mandibular central incisor in Max.Slant between normal control group and Angle’s class I malocclusion group (P < 0.05); there were significant differences in the trace of the right mandibular first molar in vertical distances between Angle’s class II malocclusion group and the other three groups (P < 0.05); there were significant differences in the trace of the right mandibular first molar in Max.Opening velocity between normal control group and Angle’s class II, III malocclusion groups (P < 0.05). There were no significant differences in free space between the four groups (P > 0.05). These results indicate that there are differences in the trace of mandibular central incisor and the trace of the right mandibular first molar in range and speed between different occlusal patterns. We can draw a conclusion that malocclusion has effects on the direction, range and speed of mandibular movement.
