摘要
目的:分析并评估应用种植钉辅助上颌快速扩弓技术(MARPE)治疗青少年上颌骨宽度不足(MTD)的扩弓效率,为制定其临床治疗方案提供参考。方法:收集20例MTD并进行MARPE治疗的青少年患者的临床资料,采用锥形束计算机断层扫描术(CBCT)测量治疗前后患者颊侧上颌宽度(BMW)、腭侧上颌宽度(PMW)、腭中缝扩大量(SE)、上颌骨性扩弓器(MSE)的扩大量(AE)和第一磨牙角度(MA)及治疗前后BMW和PMW改变值(ΔBMW和ΔPMW),计算骨性扩弓量百分比、牙槽骨的弯曲量百分比及其余效应百分比。结果:与治疗前比较,扩弓治疗后MTD患者不同牙位处BMW和PMW增大(P<0.05),双侧MA减小(P<0.05)。与第一磨牙处ΔPMW比较,第一磨牙处ΔBMW较大(t=3.047,P<0.05);与第一磨牙处SE比较,第一磨牙处ΔBMW较大(t=9.655,P<0.05)。与第一前磨牙处ΔBMW比较,第一磨牙处ΔBMW较大(P<0.05)。由第一磨牙、第二前磨牙至第一前磨牙处骨性扩弓效率百分比逐渐降低,而牙槽骨的弯曲量百分比及其余效应百分比逐渐升高。结论:应用MARPE治疗青少年MTD,可有效打开腭中缝,骨性扩弓效率可达74%以上。
Objective:To analyze and evaluate the expansion efficiency of microimplant-assisted rapid palatal expansion(MARPE)in the treatment of maxillary transverse deficiency(MTD)in the adolescents,and to provide the reference for the formulation of clinical treatment plan.Methods:The clinical materials of 20 adolescent patients with MTD,who received MARPE,were selected;the buccal maxillary width(BMW),palatal maxillary width(PMW),the amount of sutural expansion(SE),the amount of MSE appliance expansion(AE),and the first molar angle(MA)and the change values of BMW and PMW(ΔBMW andΔPMW)before and after treatment of the patients with MTD were detected by cone beam computed tomography(CBCT)before and after treatment.The percentage of bony expansion efficiency,the percentages of alveolar bone bending amount and the percentages of remaining effects were calculated.Results:Compared with before expansion treatment,the BMW and PMW at different tooth positions were increased(P<0.05),and the bilateral MA were decreased(P<0.05).Compared with theΔPMW at the first molar,theΔBMW at the first molar was larger(t=3.047,P<0.05);compared with the SE at the first molar,theΔBMW at the first molar was larger(t=9.655,P<0.05).Compared with theΔBMW at the first premolar,theΔBMW at the first molar was larger(P<0.05).The percentages of bony expansion efficiencies from the first molar and the second premolar to the first premolar were decveased,but the percentages of alveolar bending amount and the percentages of remaining effects were increased gradually.Conclusion:MARPE can effectively open the palatal suture of the adolescents with MTD,and the efficiency of bony expansion is up to 74%.
