To examine the detailed anatomy of the normal temporomandibular joint (TMJ) in a large series of patients divided into different age groups.
Cone-beam computed tomography images of 100 patients included in the study. Morphometric analysis regarding mandibular con- dyle and mandibular fossa, articular tubercle and the zygomatic arch was done. The volumetric and surface measurements of mandibular condyles (total tissue volume [TV], total bone volume [BV], bone surface area [BS] and percentage of bony tissue of the mandibular condyle [BV/TV]) were also measured.
Statistical analysis was performed and statistically significant differences according to the side of the joint, sex, and age groups were reported. Additionally, correlations between aging and all of these parameters were also determined.
TV, BV, BS and BV/TV parameters according to side, age, and sex groups were defined for normal TMJ which may help to understand the onset and progress of TMJ disorders.
在大量分为不同年龄组的患者中，研究正常颞下颌关节（TMJ）的详细解剖结构。
纳入本研究的100例患者的锥形束计算机断层扫描图像。对下颌髁突、下颌窝、关节结节和颧弓进行形态计量分析。还测量了下颌髁突的体积和表面积（总体积[TV]、总骨体积[BV]、骨表面积[BS]和下颌髁突骨组织百分比[BV/TV]）。
进行了统计分析，并报告了根据关节侧别、性别和年龄组的统计学显著差异。此外，还确定了衰老与所有这些参数之间的相关性。
为正常颞下颌关节定义了根据侧别、年龄和性别组的TV、BV、BS和BV/TV参数，这可能有助于理解颞下颌关节疾病的发病和进展。
