目的：探讨微种植钉支抗矫正对后牙锁牙合患者髁突形态及对称性的影响。方法：收取2014年1月-2015年1月到我院就诊的20例恒牙期安氏I类单侧后牙正锁牙合的患者，20例患者均采用微种植钉支抗矫正。采用颅颌面锥形束CT成像技术观察患者矫治前后髁突的变化，将各自正常对侧后牙作为对照，进行比对研究。结果：20例后牙锁牙合患者矫治前的髁突高度、髁突表面积及髁突体积都高于正常对照后牙[（4.61±1.09 Vs 3.52±0.29）mm、（1201.32±121.37 Vs 1010.23±111.26）mm2、(1409.13±168.24 Vs 1243.35±147.08)mm3]；20例后牙锁牙合患者矫治后的髁突高度（3.60±0.54）mm、髁突表面积（1009.15±112.37）mm2、髁突体积（1241.03±137.18）mm3都明显低于矫治前。与正常对照后牙比较，差异无统计学意义（P＞0.05）。结论：早期矫治可以有效改变髁突的形态，提高后牙的咬合度及对称性，值得临床推广应用。
目的：探討微種植釘支抗矯正對後牙鎖牙閤患者髁突形態及對稱性的影響。方法：收取2014年1月-2015年1月到我院就診的20例恆牙期安氏I類單側後牙正鎖牙閤的患者，20例患者均採用微種植釘支抗矯正。採用顱頜麵錐形束CT成像技術觀察患者矯治前後髁突的變化，將各自正常對側後牙作為對照，進行比對研究。結果：20例後牙鎖牙閤患者矯治前的髁突高度、髁突錶麵積及髁突體積都高于正常對照後牙[（4.61±1.09 Vs 3.52±0.29）mm、（1201.32±121.37 Vs 1010.23±111.26）mm2、(1409.13±168.24 Vs 1243.35±147.08)mm3]；20例後牙鎖牙閤患者矯治後的髁突高度（3.60±0.54）mm、髁突錶麵積（1009.15±112.37）mm2、髁突體積（1241.03±137.18）mm3都明顯低于矯治前。與正常對照後牙比較，差異無統計學意義（P＞0.05）。結論：早期矯治可以有效改變髁突的形態，提高後牙的咬閤度及對稱性，值得臨床推廣應用。

objective To explore the effects of micro-screw implant anchorage on condylar shape and symmetry in patients with posterior scissors-bite. Methods A total of 20 Class I unilateral posterior scissors-bite patients visiting our hospital from January 2013 to February 2014 were included in this study.All patients were given micro screw implant anchorage.CT imaging was used to observe the changes in condylar before and after treatment.Their normal right lateral teeth were used as controls. Results The condylar height,condylar surface area and condylar volume of 20 case patients with posterior scissors-bite were higher than that normal controls before treatments[(4.61 ± 1.09 Vs 3.52 ± 0.29)mm,(1201.32 ± 121.37 Vs 1010.23 ± 111.26)mm2,(1409.13 ± 168.24 Vs 1243.35 ± 147.08) mm3].The condylar height(3.60 ± 0.54)mm,condylar surface area(1009.15 ± 112.37)mm2 and condylar volume(1241.03 ± 137.18)mm3 were significantly lower after treatments.There was no statistically significant difference compared with normal group(P>0.05). Conclusion Early correction can effectively change the shape of the condyle and improve the degree of posterior occlusal and symmetry and is worthy of clinical use.
