目的 比较使用不锈钢种植钉支抗内收上颌前牙时,两种不同植入部位种植钉的稳定性.方法 选取因上颌前突而行拔牙矫治的患者72例,其中男性28例,女性44例,均使用不锈钢种植钉支抗技术内收上颌前牙.对其中14例男性、22例女性患者于上颌5、6间颊侧植入种植钉,对另14例男性、22例女性患者于6、7间颊侧植入种植钉.比较两种不同植入部位种植钉的松动率.结果 两种不同植入部位种植钉松动率的比较,位于上颌5、6间颊侧植入组,松动率为23.38%,位于6、7间颊侧植入组,松动率为6.74%,前者松动率高于后者,其差异有统计学意义(P=0.002).结论 使用不锈钢种植钉支抗内收上颌前牙时,植入于上颌6、7间颊侧,种植钉稳定性优于植入于上颌5、6间颊侧.
目的 比較使用不鏽鋼種植釘支抗內收上頜前牙時,兩種不同植入部位種植釘的穩定性.方法 選取因上頜前突而行拔牙矯治的患者72例,其中男性28例,女性44例,均使用不鏽鋼種植釘支抗技術內收上頜前牙.對其中14例男性、22例女性患者于上頜5、6間頰側植入種植釘,對另14例男性、22例女性患者于6、7間頰側植入種植釘.比較兩種不同植入部位種植釘的鬆動率.結果 兩種不同植入部位種植釘鬆動率的比較,位于上頜5、6間頰側植入組,鬆動率為23.38%,位于6、7間頰側植入組,鬆動率為6.74%,前者鬆動率高于後者,其差異有統計學意義(P=0.002).結論 使用不鏽鋼種植釘支抗內收上頜前牙時,植入于上頜6、7間頰側,種植釘穩定性優于植入于上頜5、6間頰側.

Objective To compare the stability of stainless mini-implants retracting maxillary anterior teeth in two different implanted sites.Methods 72 patients (28 males,44 females) of maxillary protrusion were selected to retract anterior teeth with stainless mini-implants anchorage.14 males and 22 females were bucally implanted between maxillary second premolar and first molar.The other 14 male and 22 female were bucally implanted between first and second molars.The failure rates of mini-implants in two different implanted sites were compared.Results Group of implants bucally located between maxillary second premolar had a 23.38% failure rate.Group of implants bucally located between maxillary first and second molars had a 6.74% failure rate.The difference was statistically significant(P=0.002).Conclusions The stability of stainless mini-implants anchorage between maxillary first and second molars,is better than that of bucally located implants between maxillary seond premolar and first molar.
