[摘要] 目的 探索自鎖托槽矯治器用于牙頜畸形患者正畸中的臨床價(jià)值。 方法 選取2015年3月11日～2016年3月11日期間我院收治的牙頜畸形患者100例，將其隨機(jī)化分組，兩組各50例，對照組和觀察組分別采用傳統(tǒng)金屬托槽治療和自鎖托槽矯治器治療，隨后對比兩組患者的矯治初期疼痛程度、托槽脫落情況、菌斑指數(shù)（PLI）、牙齦指數(shù)（GI）、齦溝出血指數(shù)（SBI）、谷草轉(zhuǎn)氨酶（AST）含量。 結(jié)果 觀察組患者的PLI（1.14±0.36）、GI（1.02±0.05）、SBI（1.52±0.12）、治療后24 h AST含量（95.47±5.69）×10-6 U/L、治療后48 h AST含量（202.98±5.37）×10-6 U/L、治療后168 h AST含量（321.77±11.05）×10-6 U/L、3個(gè)月托槽脫落率（0）、6個(gè)月托槽脫落率（0）、12個(gè)月托槽脫落率（2.00%）、治療后24 h疼痛評分（1.15±0.23）分、治療后48 h疼痛評分（1.02±0.38）分、治療后72 h疼痛評分（0.13±0.09）分均優(yōu)于對照組（P<0.05）。 結(jié)論 對牙頜畸形患者實(shí)施自鎖托槽矯治器治療效果顯著。

　　[Abstract] Objective To explore the clinical value of self-ligating appliance for orthodontics in the patients with dento-mandibular deformity. Methods 100 patients with dento-mandibular deformity who were admitted to our hospital from March 11， 2015 to March 11， 2016 were selected. The patients were divided into two groups according to random method， with 50 patients in each group. The control group and the observation group were given traditional metal brackets and self-ligating appliance respectively for treatment. Afterwards， the pain level， bracket detachment， plaque index（PLI）， gingival index（GI）， sulcus bleeding index（SBI） and aspartate aminotransferase（AST） were compared between the two groups at the initial stage of correction. Results In the patients in the observation group， the PLI was（1.14±0.36）， GI was（1.02±0.05）， SBI was（1.52±0.12）， 24 hours after treatment AST content was（95.47±5.69）×10-6 U/L， 48 hours after treatment AST content was（202.98±5.37）×10-6 U/L， and 168 hours after treatment AST content was（321.77±11.05）×10-6 U/L， the 3-month brackets detachment rate was 0， 6-month brackets detachment rate was 0， and 12-month brackets detachment rate was 2.00%， the pain scores at 24 hours after treatment was（1.15±0.23）， the pain score at 48 hours after treatment was（1.02±0.38）， and the pain scores at 72 hours after treatment was（0.13±0.09）， which were significantly better than those in the control group（P<0.05）. Conclusion The self-ligating appliance for orthodontics in the patients with dento-mandibular deformity has a significant curative effect.
