摘要
目的 对比成人上颌牙弓骨性狭窄横向发育不足患者应用不同扩弓疗法的可行性。方法 将86例需进行上颌扩弓的患者随机分为A(43例)、B(43例)两组,其中A组采用种植钉辅助上颌快速扩弓(MARPE),B组采用快速上颌扩弓矫正(RME)。测量比较治疗前及治疗3个月后时两组患者的前、后部腭中缝宽度,鼻腔宽度,鼻底基骨宽度,上颌牙槽宽度,第一磨牙间宽度,左、右磨牙倾斜度,左、右牙槽嵴高度。结果 进行扩弓治疗3个月后,两组患者前、后部腭中缝宽度,鼻腔宽度,鼻底基骨宽度,上颌牙槽宽度,第一磨牙间宽度、第一双牙尖宽度均较治疗前有显著提高(P<0.05),且A组明显高于同一时间B组(P<0.05);A组左、右磨牙倾斜度均较治疗前无明显变化(P>0.05),但明显小于同时间B组(P<0.05),B组左、右磨牙倾斜度治疗3个月后较治疗前增大,且差异有统计学意义(P<0.05)。结论 MARPE相比于RME在成人上颌牙弓骨性狭窄横向发育不足中能有效开展成人腭中缝,扩宽效果更好,同时能减少一定牙扩弓时矫正力带来的副作用。
Objective To compare the feasibility of different arch expansion therapies in adult patients with transverse growth deficiency of maxillary dental arch stenosis.Methods 86 patients who needed maxillary arch expansion were random-ly divided into group A(43 cases)and group B(43 cases).Group A was treated withmicroimplant-assisted rapid palatal ex-pansion(MARPE)while group B was given rapid maxllary expansion(RME).The anterior and posterior midpalatal suture widths,nasal cavity width,nasal base bone width,maxillary alveolar width,width between first molars,left and right molar inclina-tions,and left and right alveolar ridge heights were measured and compared between the two groups before treatment and af-ter 3 months of treatment.Results After 3 months of arch expansion therapy,the anterior and posterior midpalatal suture widths,nasal cavity width,nasal base bone width,maxillary alveolar width,width between first molars and width of first tooth apex were significantly enhanced in the two groups compared to before treatment(P<0.05),and the above indicators in group A were significantly wider than those in group B at the same time point(P<0.05).The inclinations of left and right molars in group A had no significant changes compared with those before treatment(P>0.05),but were significantly lower than those in group B(P<0.05).The inclinations of left and right molars in group B were increased afer 3 months of treatment compared to before treatment(P<0.05).Conclusion Compared with RME,MARPE can better effectively develop the midpalatal suture in adults with transverse growth deficiency of maxillary dental arch stenosis,and MARPE has better expansion effect and can reduce the side effects caused by correction force during dental arch expansion.
