摘要
目的观察分析年轻成人使用种植钉辅助螺旋扩弓器上颌快速扩弓后的效果。方法选取32例扩弓的年轻成人患者,随机分为实验组(16例),行种植钉辅助螺旋扩弓器扩弓;对照组(16例),行传统螺旋扩弓器扩弓。两组患者分别测量扩弓前后上颌左右第一前磨牙、第一磨牙之间水平横向宽度,以及腭弓连线与腭中缝的交汇点以下5 mm水平横向宽度,双侧上颌第一磨牙牙体长轴间夹角。实验组患者扩弓前和扩弓后不同时期(0、3、6、12个月)上颌左右第一磨牙连线与腭中缝的交汇点以下5 mm水平横向宽度。分析扩弓前后宽度变化,牙齿牙槽突的倾斜移位情况和实验组腭中缝扩大后的稳定性。结果两组扩弓方式均能有效使上颌横向扩大,实验组以腭中缝的扩大为主,对照组以牙齿牙槽突的颊向倾斜移位为主。实验组扩弓1年内腭中缝的扩大有复发。结论年轻成人使用种植钉辅助螺旋扩弓器快速扩弓能够有效地使上颌横向宽度扩大,以腭中缝扩大为主。在1年内腭中缝的扩大有复发。
Objective To observe and analyze the effect of the rapid maxillary expansion after planting nail assisted screw expander in young adults. Methods 32 cases of maxillary expansion of young adult patients were randomly divided into experimental group（ 16 cases）,who underwent implant assisted screw,and control group（ 16 cases）,who underwent conventional screw expansion. For the two groups of patients,the horizontal width between the left and right of the first premolar and the first molar before/after the expansion,the horizontal width 5 mm below the intersection of palatal arch connection and palatal raphe,the angle between the long axis of the bilateral maxillary first molar tooth were measured. For the experimental groups,the horizontal width 5 mm below the intersection of left and right maxillary first molar connection and the palatal raphe were measured before arch expansion and arch expansion in different periods（ 0 months,3 months,6 months,12 months）. Analyze the width change before and after the expansion,the inclination and displacement of alveolar process of tooth,the stability of the experimental group after palatal expansion. Results The expansion of the maxillary arch could be effectively enlarged in the two groups. The experimental group was mainly with palatal expansion. The control group was mainly with the buccal inclination of alveolar process. The experimental group within a year of the expansion of the palate raphe could relapse. Conclusion The lateral width of the maxillary can be effectively enlarged by the rapid expansion of planting nail assisted screw expander in the young adults,especially the palate raphe. During a year the expansion of the palate raphe can relapse.
