摘要: 目的 对患有颞下颌关节紊乱病的安氏Ⅱ类2分类患者给予平面导板矫治器进行治疗,分析其临床效果,为正畸临床提供指导意义。 方法 选择2013 年1月到2014年12月在南京医科大学附属口腔医院就诊的安氏Ⅱ类2分类错牙合伴颞下颌关节紊乱病患者20例,用美国Myotronics K7神经肌肉牙医学分析系统记录每位患者带用平面导板矫治器治疗前、后的下颌运动轨迹及髁突震动频率的变化。 结果 ①平面导板矫治器治疗后下颌的最大张口度、前伸、侧方运动与治疗前相比变化不大,无统计学意义(P>0.05)。②平面导板矫治器治疗后开口型牙合位偏移与治疗前相比结果有统计学意义(P<0.05)。③平面导板矫治器治疗后颞下颌关节的运动振幅与治疗前相比结果有统计学意义(P<0.05)。 结论 平面导板矫治器有利于深覆牙合患者打开咬合,改善下颌运动模式,缓解颞下颌关节紊乱病相关症状,为临床治疗提供了指导意义。

Abstract: Objective To study the clinical therapeutic effects of plane plate on Class Ⅱ division 2 malocclusion patients with temporomandibular disorders (TMD).Methods 20 outpatients who had Class Ⅱ division 2 malocclusion with temporomandibular joint disorders from January 2013 to December 2014 at Jiangsu Provincial Stomatological Hospital of Orthodontics and TMJ Branch were selected in this study.All were treated by the plane plates and used United States Myotronics K7 (Neuromuscular Dentistry analysis system) was used to record their changes of condylar trajectory and vibration frequency before and after using the flat-screen guide appliance.Results ①After being treated by plane plate,maximum mouth opening,protrusion and lateral movement all had little changes compared with the previous treatment (P> 0.05).②The style of mouth opening was changed after treatment (P<0.05).③Joint vibrations were statistically changed compared with those before treatment (P<0.05).Conclusions The plane plant can lead to open bite on deep overbite patients,improve jaw movement patterns,and relieve related symptoms of temporomandibular diseases,thus providing guidance for clinical treatment.
