摘要
目的利用4D下颌运动轨迹描记仪(4D~(TM) Jaw Motion System)记录下颌运动轨迹,测量计算切导斜度、髁导斜度等相关参数,初步探讨其获得的参数值用于关系转移的精确性和可靠性。方法选取个别正常、无颞下颌关节疾患等符合入选标准的30名志愿者作为受试对象,男女各15例,平均年龄在25～35岁之间,利用4D下颌运动轨迹描记仪测量下颌运动的左右侧Bennett角、左右侧前伸髁导斜度以及前伸切导斜度等5组参数,同时运用传统机械式架测量法计算相同参数,测量3次,取平均值。所得数据采用t检验进行统计学处理。结果 4D下颌运动轨迹描记仪和机械式架测量所得参数平均值分别为:(1)右侧Bennett角:(24.81±5.23)°和(25.35±4.05)°。(2)左侧Bennett角:(24.20±8.12)°和(26.58±4.98)°。(3)右侧前伸髁导斜度:(37.60±9.11)°和(34.13±6.74)°。左侧前伸髁导斜度:(38.25±10.32)°和(35.60±8.40)°。(5)前伸切导斜度:(39.97±9.43)°和(41.14±11.05)°。经过统计学分析,测量结果均在正常值范围内,两者之间差异无统计学意义(P>0.05)。结论运用4D下颌运动轨迹描记仪测量架相关参数所得数值具有精确性和可重复性,操作简便,舒适度好。
Objective The purpose of this research is to apply 4D~(TM) Jaw Motion System for recording the track of mandibular movement and measuring relevant paraments, including incisal guidance inclination and condylar guidance inclination, so as to explore its precision and reliability. Methods Thirty subjects without malocclusion and TMJDS were selected for this experiment. We aimed to measure 5 paraments including Bennett angle, incisor inclination and condylar inclination, taking advantage of 4D~(TM) Jaw Motion System and traditional articulator for the comparison of mean difference. Result All subjects were successfully operated and the paraments obtained are as follows: ① The right Bennett angle for 4D~(TM) Jaw Motion System and articulator are(24.81±5.23)° and(25.35±4.05)°, and the left are(24.20±8.12)° and(26.58±4.98)°. ② The right condylar inclination angle are(37.60±9.11)° and(34.13±6.74)°, simultaneously the left are(38.25±10.32)° and(35.60±8.40)°. ③ The incisor inclination are(39.97±9.43)° and(41.14±11.05)°, respectively. Statistical analysis showed there was no significant difference between digital and conventional methods. Conclusion 4D~(TM) Jaw Motion System can be used to record and analyze the mandibular movement and has already shown its precision and reproducibility of transfer values. This measurement is more convenient and simpler for operation, and patients feel comfortable as well.
