目的 探讨传动直丝弓技术和MBT滑动直丝弓技术矫治成人双颌前突患者的临床效果.方法 选择双颌或双牙弓前突患者40例,将其完全随机分为两组,传动组20例,应用传动直丝弓矫治;MBT组20例,应用MBT滑动直丝弓结合口外弓或种植钉辅助支抗治疗.比较两组头颅侧位X线治疗前后及治疗差值的组间差异.结果 平均疗程传动组为(19±4)个月,MBT组为(23±4)个月,差异有统计学意义(P<0.05);与治疗前比较,两组患者U1/SN、U1/NA、U1-NA、L1/NB、L1-NB、U1-AP、L1-AP、UL-EP、LL-EP均显著减小(P<0.01);U1/L1、鼻唇角和Z角均增大(P<0.05);MP/SN传动组增加1.93°(P<0.05),MBT组增加0.81°(P>0.05).除MP/SN差异有统计学意义外(P<0.05),其余差异均无统计学意义(P>0.05),但上中切牙内收量U1/NA传动组(-20.95±8.79)°明显大于MBT组(-16.00±6.52)°.结论 未使用额外支抗的传动技术和使用强支抗的MBT技术治疗双颌前突患者均能得到满意的软、硬组织结果.传动直丝弓技术能较早改善患者软组织侧貌,但上前牙有过于直立趋势,临床应注意上前牙的转矩控制.

Objective To evaluate the curative effect by using transmission straight wire appliance in treatment of adult patients with protruding,to compare with MBT straight wire technique,and to discuss their similarities and differences.Methods Totally 40 protruding patients were assigned into two groups randomly:the transmission straight wire technique group were treated with transmission straight wire appliance,and the MBT straight wire technique group were treated with MBT appliance together with extraoral arch or screw implant anchorage.Cephalometric measurements were compared before and after treatment.Results Average period of treatment was (19 ±4) months for transmission group and (23 ± 4) months for MBT group.The difference was statistically significant (P<0.05).After treatment,U1/SN,U1/NA,U1-NA,L1/NB,L1-NB,U1-AP,L1-AP,UL-EP,LL-EP were significantly reduced for both patients groups (P<0.01).U1/L1,nasolabial angle and z angle were increased for both groups (P<0.05).MP/SN increased by 1.93°(P<0.05)for transmission group vs.0.81° (P>0.05) for MBT group.There was no statistically significant difference between the two groups (P>0.05) except MP/SN (P<0.05).However,the retraction of anterior teeth in transmission group was greater than that of MBT group,and U1/NA changed (-20.95±8.79)° in transmission group vs.(-16.00 ± 6.52)° in MBT group.Conclusions Both techniques can achieve satisfactory results for protruding cases.The transmission technology can improve soft tissue profile quicker,but anterior teeth have excessive vertical trend,where attention should be paid to control torque on anterior teeth.
