摘　　要：目的:比较[牙合]垫联合隐形矫治与单纯隐形矫治用于第二磨牙锁[牙合]矫治的效果。方法:选择第二磨牙中、重度锁[牙合]患者30例(女16例,男14例),均为双侧锁[牙合]。年龄16.5~28岁。5例接受单纯隐形矫治(对照组),25例首先戴用[牙合]垫加弹性牵引解除锁[牙合],再行隐形矫治(联合组)。比较两组的矫治效果。结果:联合组矫治进程顺利,平均用时18个月,其中应用[牙合]垫加弹性牵引解除锁结关系需1.5~3个月。而对照组患者均未能顺利完成矫治,在戴用约10副隐形矫治器后,仍易脱套,暂停隐形矫治,重启方案后,约10副隐形矫治器后解除锁[牙合],用时14~15个月,相对于联合组多花费约12个月。结论:对于中、重度第二磨牙锁[牙合],在隐形矫治前应用[牙合]垫加局部交互牵引可顺利完成治疗,减少治疗时间。Aim:To compare the efficacy of jaw pads with invisible aligner or invisible aligner alone in correction of second molar scissor bite.Methods:Thirty patients(16 females and 14 males)with moderate and severe scissor bite of the bilateral second molar were selected.The age ranged from 16.5 to 28 years.The patients were allocated into 2 groups,control group(n=5)was treated by invisible aligners,and in the combination group(n=25),scissor bite was first released by wearing jaw pads and cross elastics,and then by invisible aligners.The treatment efficacy was compared.Results:The treatment was successfully completed in the combination group,with an average time of 18 months,among which,the time to release the scissor bite using jaw pads plus elastic traction was 1.5 to 3 months.However,all patients in control group failed to complete the treatment;after wearing about 10 pairs of appliances,the condom was still easily removed;the treatment was suspended,the program was restarted,and the lock was released after about 10 pairs of appliances,and the time spent was 14-15 months;the wasted time was about 12 months compared with the combination group.Conclusion:For patients with moderate and severe scissor bite of the second molars,applying the jaw pad and cross elastics before the invisible aligner could successfully accomplish the treatment program and shorten the treatment time.
