The objective of this series is to observe and analyze movements of the temporomandibular joint (TMJ). With the information from these studies, orthopedic standards for jaw movements will be established in further investigations according to the neutral-zero method used in general orthopedics. Any restricted range of motion can thus be defined as a deviation from these standards. Direct interpretation and objective evaluation of joint functions has major practical implications. With the aid of computerized axiography, mediotrusive movements of 48 asymptomatic volunteers and 66 jaw patients were evaluated. The movements performed were either free or guided. The mean curve lengths, as well as the Bennett angles at 3 mm and at the end point were recorded. An average group was defined, containing the values of 50% of all volunteers. The interquartile range was calculated for lengths of mediotrusive movements as well as for Bennett angles. The average range of free mediotrusive movement for female volunteers was 11.06-11.98 mm (mean 11.55 mm) on the right side and 10.47-11.75 mm (mean 11.24 mm) on the left side. Male volunteers showed an average range of 10.23-11.54 mm (mean 11.1 mm) on the right side and 10.24-11.73 mm (mean 11.12 mm) on the left side. The values for female patients amounted to 9.95-1.66 mm (mean 10.8 mm) on the right side and 9.75-11.28 mm (mean 10.55 mm) on the left side. The average range for male patients was 9.06-9.71 mm (mean 9.54 mm) on the right side and 9.17-10.23 mm (mean 9.73 mm) on the left side. The average range for Bennett angles at maximum excursion in free mediotrusive movement was between 0.41 and 5.89 degrees (mean 4.43 degrees) in the volunteers on the right side and between 2.45 and 10.07 degrees (mean 6.87 degrees), respectively, on the left side. The values for patients amounted to 0.19-12.65 degrees (mean 6.93 degrees), on the right side and 1.71-14.15 degrees (mean 6.73 degrees) on the left side.
本系列研究的目的是观察和分析颞下颌关节(TMJ)的运动。根据这些研究所得信息,将依据普通骨科中使用的中立-零位法,在后续研究中确立下颌运动的矫形标准。因此,任何受限的运动范围都可被定义为偏离这些标准。对关节功能进行直接解读和客观评估具有重大的实际意义。借助计算机化轴面断层摄影术,对48名无症状志愿者和66名下颌患者的侧方运动进行了评估。所进行的运动包括自由运动或引导运动。记录了平均曲线长度以及3毫米处和终点处的贝内特角。定义了一个平均组,包含所有志愿者50%的值。计算了侧方运动长度以及贝内特角的四分位距。女性志愿者自由侧方运动的平均范围右侧为11.06 - 11.98毫米(平均11.55毫米),左侧为10.47 - 11.75毫米(平均11.24毫米)。男性志愿者右侧平均范围为10.23 - 11.54毫米(平均11.1毫米),左侧为10.24 - 11.73毫米(平均11.12毫米)。女性患者的值右侧为9.95 - 1.66毫米(平均10.8毫米),左侧为9.75 - 11.28毫米(平均10.55毫米)。男性患者的平均范围右侧为9.06 - 9.71毫米(平均9.54毫米),左侧为9.17 - 10.23毫米(平均9.73毫米)。在自由侧方运动最大偏移时,志愿者右侧贝内特角的平均范围在0.41至5.89度之间(平均4.43度),左侧分别在2.45至10.07度之间(平均6.87度)。患者的值右侧为0.19至12.65度(平均6.93度),左侧为1.71至14.15度(平均6.73度)。
