摘要
目的:对低位咬合伴颞下颌关节结构紊乱患者进行咬合重建修复,分析其临床效果。方法:观察14例符合条件患者治疗前、暂时性垫治疗后、永久性修复治疗后临床症状、关节间隙及肌电图的变化。结果:(1)暂时性垫及永久性修复治疗后临床症状和关节间隙与治疗前相比,结果均有统计学意义(P<0.05)。(2)静息状态下垫治疗及永久性修复后,颞肌前束(TA)和咬肌(MM)肌电活动减弱,有统计学意义(P<0.05);但在最大紧咬状态下垫治疗后肌电活动变化无统计学意义(P>0.05),而永久性修复后肌电活动显著增强,变化有统计学意义(P<0.05)。结论:咬合重建缓解了颞下颌关节相关症状,永久性修复较暂时性修复达到了更为理想的咬合接触状态,咬合过程中咀嚼肌的功能得到了充分的发挥。
Objective： To discuss and analyze the clinical effects of occlusal reconstruction therapy for the patients with infraocclusion and temporomandibular internal derangement. Methods： 14 reasonable patients were chosen and their clinical symptoms, joint spaces and electromyographics were observed at three stages- pretherapy, temporary occlusal pad therapy and permanent reparation. Results： （1） Compared with pretherapy, changes of clinical symptoms and joint spaces after temporary occlusal pad therapy and permanent reparation had statistical significant differences （P 〈0.05）. （2） Myoelectricities of TA and MM after temporary occlusal pad and permanent reparationtherapy diminished obviously at quiescent condition （P 〈0.05）. At max biting condition, myoelectricity changes of temporary occlusal pad therapy had no statistical significance （P 〉0.05）, but permanent reparation had obvious statistical significance （P 〈0.05）. Conclusion： Occlusal reconstruction can relieve symptoms of TMJ, permanent restoration achieves more ideal biting touch conditions.
