摘要
目的研究伴有内倾性深覆的颞下颌关节紊乱病患者正畸治疗前后症状的变化,探讨内倾性深覆与颞下颌关节紊乱病的相关性。方法伴内倾性深覆的颞下颌关节紊乱病患者40例,定量计算每例患者正畸治疗前后的Fricton颞下颌关节紊乱指数(craniomandibular index,CMI),比较其治疗前后的变化。结果伴内倾性深覆的颞下颌关节紊乱病患者经正畸治疗后,内倾性深覆均得到解除,恢复良好的外形及咬合关系,临床症状均得到改善,治疗后2年时评价发现,颞下颌关节功能障碍指数、肌肉压痛指数和CMI分别由治疗前的0.321±0.091、0.020±0.015、0.171±0.053下降为0.062±0.021、0.003±0.004、0.033±0.012,差异均有统计学意义。结论伴内倾性深覆的颞下颌关节紊乱病患者经正畸治疗解除内倾性深覆后,颞下颌关节紊乱症状可明显改善,内倾性深覆与颞下颌关节紊乱病关系较为密切。
Objective To evaluate the clinical effects of orthodontic treatment for temporomandibular disorders（TMD） with lingual tipping deep overbite.Methods Forty TMD patients with lingual tipping deep overbite were selected.Fricton＇s craniomandibular index（CMI） were calculated before and after treatment.Results After2 year treatment,the patients＇ disorder index,pain index and CMI were 167.04,145.64 and 167.22 respectively.They all significantly reduced when compared with before treatment with statistical difference（P=0.000）,and the patients got a better result both in external form and function.Conclusion Lingual tipping deep overbite and TMD have a significant relativity.The forward effect of orthodontic treatment is still uncertain and long-term observation is necessary.
