| 中文摘要:目的 研究颞下颌关节窝在安氏Ⅱ类错畸形成年个体间的形态差异。方法 选取82名骨性均角成年患者的双侧颞下颌关节CBCT(cone-beam computed tomography)影像数据用于研究,并根据矢状骨面型、磨牙关系及上前牙倾斜度分为骨性Ⅰ类安氏Ⅱ1类组,骨性Ⅰ类安氏Ⅱ2类组,骨性Ⅱ类安氏Ⅱ1类组及骨性Ⅱ类安氏Ⅱ2类组。对颞下颌关节窝角度和线性量指标进行测量评估,并对各组之间的差异进行统计学分析。结果 功能性关节结节后斜面倾斜度在相同咬合关系的骨性Ⅰ类与骨性Ⅱ类错畸形组间及相同矢状骨面型的两安氏Ⅱ类错畸形组间差异均有统计学意义(P＜0.05),而解剖性关节结节后斜面倾斜度组间比较,差异均无统计学意义(P＞0.05),关节窝长度、关节窝深度、关节窝长深比在不同矢状骨面型伴同种牙性Ⅱ类错畸形组间比较,差异无统计学意义(P＞0.05)。结论 安氏Ⅱ类错伴骨性I类及骨性Ⅱ类个体间的颞下颌关节窝形态存在差异。 |

| Abstract:Objective To evaluate the morphological differences of the glenoid fossa in adult patients with Angle′s Class Ⅱ malocclusions. Methods The cone-beam computed tomography (CBCT) images of bilateral temporomandibular joints in 82 patients with average mandibular angle were selected. The patients were divided into 4groups including skeletal class Ⅰ with Angle′s Class Ⅱ division 1, skeletal class Ⅰ with Angle′s Class Ⅱ division 2, skeletal class Ⅱ with Angle′s Class Ⅱ division 1 and skeletal class Ⅱ with Angle′s Class Ⅱ division 2. Angular and linear measurements of the glenoid fossa were evaluated and the differences among the groups were statistically analyzed. Results The functional articular eminence inclination (AEI-BFL) showed statistical differences between skeletal class I and skeletal class II groups with the same occlusal relationship and between the two Angle′s Class Ⅱ groups with the same sagittal skeletal relationships (P<0.05), while the anatomical articular eminence inclination (AEI-TRL) showed no statistical differences among groups (P>0.05). The width of the glenoid fossa (GFW), the depth of the glenoid fossa (GFD), the ratio of the GFW to the GFD (GFW/GFD) showed no statistical differences among different groups (P＞0.05).Conclusion The morphology of the glenoid fossa revealed differences in the Angle′s Class Ⅱ with skeletal class I and class Ⅱ patients. |
