目的 比较微螺钉种植体支抗与口外弓增强磨牙支抗的效果.方法 选择上颌前突的患者30名,随机分为两组,分别采用种植体支抗和口外弓支抗,对两组治疗前后的X线头颅侧位片测量并通过Pancherz分析法进行对比分析,同时记录并比较两组的正畸疗程.结果 种植支抗组较口外弓组在覆盖、磨牙关系以及上中切牙位置方面改善明显,其差异有显著性(P＜0.05);种植支抗组较口外弓组上磨牙佗置更为稳定(P＜0.05),正畸疗程更短(P＜0.05).结论 种植支抗比传统口外弓支抗增强上颌支抗的效果更为理想.
目的 比較微螺釘種植體支抗與口外弓增彊磨牙支抗的效果.方法 選擇上頜前突的患者30名,隨機分為兩組,分彆採用種植體支抗和口外弓支抗,對兩組治療前後的X線頭顱側位片測量併通過Pancherz分析法進行對比分析,同時記錄併比較兩組的正畸療程.結果 種植支抗組較口外弓組在覆蓋、磨牙關繫以及上中切牙位置方麵改善明顯,其差異有顯著性(P＜0.05);種植支抗組較口外弓組上磨牙佗置更為穩定(P＜0.05),正畸療程更短(P＜0.05).結論 種植支抗比傳統口外弓支抗增彊上頜支抗的效果更為理想.

Objective To compare the clinical effects of microscrew implant and headgear in anchorage control Methods Thirty cases with maxillary protrusion were selected,and randomly divided into two groups,using microscrew implant and headgear respectively.Cephalometric measurements before and after the treatment and Pancherz's analysis was used to evaluate the changes before and after the treatment.the total treatment time was recorded.Resuits Cases with implant changed more evidently than those with headgear in overjet,molar relationship and position of upper ineisor(P＜0.05);The position of upper molar was more stable and the treatment time was shorter in implant group,compared with headgear group(P＜0.05).Conclusions Microscrew implant could provide better anchorage control than headgear.
