【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。
[Abstract]:Objective to observe and analyze the effect of rapid maxillary arch expansion with implant nail assisted spiral arch expander in young adults. Methods 32 young adult patients were selected and randomly divided into experimental group (n = 16). The implant nail was used to assist the expansion of the spiral arch expander. In the control group, 16 cases were treated with the traditional spiral arch expander. The maxillary first premolar and the horizontal transverse width between the first molar and the maxillary were measured before and after the expansion. The horizontal transverse width of the line between palatine arch and palatine suture, the angle between the long axis of bilateral maxillary first molar, and the horizontal transverse width below the junction point of palatine suture. 12 months) the horizontal transverse width of 5 mm below the junction point between the first molar line of the maxillary left and right and the midpalatal suture. The width changes before and after arch expansion were analyzed. Results both the two groups of expansion arch can effectively expand the maxillary transverse expansion, the experimental group mainly expanded palatine suture. In the control group, buccal oblique displacement of the alveolar process was dominant, and the palatine suture recurred in the experimental group within 1 year of arch expansion. Conclusion the rapid expansion of the maxillary transverse width can be effectively achieved in young adults using the implant nail assisted helical arch expander. Expansion. The expansion of palatine suture was predominant. The enlargement of palatine suture recurred within one year.
