目的:第三磨牙伸长与颞颌关节功能紊乱病(TMD)的临床相关性研究方法:收集TMD并伴有第三磨牙伸长病例65例,男20例,女45例,平均年龄32.2岁。上颌牙第三磨牙伸长55例,下颌牙第三磨牙伸长10例。均为单侧。分别记录拔除伸长第三磨牙前后TMD患者开口度,开口型,关节区疼痛、弹响等TMD相关体征。结果:65例患者中有55例(84.6%)开口度改善超过0.5cm。58例(89.2%)关节绞锁或咬合偏斜消失或减轻。关节区疼痛发作减少或疼痛减轻41例(63.1%),关节弹响减轻或消失25例(38.5%)。结论:通过拔除伸长的第三磨牙可以缓解TMD的临床症状,尤其对于改善开口型及开口度具有较好作用。
Objective: The third molars elongation and temporomandibular joint dysfunction disease (TMD) clinical correlation study method: collecting TMD and accompanied by a third molar extended cases of 65 cases, 20 males and 45 females, with an average age of 32.2 years . The maxillary third molar extended 55 cases, mandibular third molar extended 10 cases. All are unilateral. TMD-related signs of open TMD patients, open type, joint pain, snapping, etc. were recorded before and after removal of the third molar. Results: Of the 65 patients, 55 (84.6%) improved the opening more than 0.5 cm. Fifty-eight (89.2%) articular twisting or occlusion skew disappeared or lightened. There were 41 cases (63.1%) with reduction of pain or reduction of pain in joint area and 25 cases (38.5%) with reduction or disappearance of joint snapping. Conclusion: The clinical symptoms of TMD can be relieved by pulling out the extended third molars, especially for improving the open type and the open degree.
