目的：比较Damon Q自锁和3M金属托槽非拔牙矫治轻中度上颌拥挤软硬组织及牙弓变化的研究。方法选择正畸矫治患者87例，以上颌拥挤程度和采用的矫治器种类分为Ⅰ度、Ⅱ度拥挤Damon Q自锁托槽组（41例），Ⅰ度、Ⅱ度拥挤3M金属托槽组（46例）。测量治疗前后头颅侧位片及模型，整理数据采用配对t检验和成组t检验分析。结果非拔牙矫治上颌Ⅰ度、Ⅱ度拥挤时，两种托槽治疗后上颌牙弓宽度和牙弓长度均有增大，但2组间变化量差异无统计学意义。上颌Ⅱ度拥挤时，比较2组软组织测量项目鼻唇角、上唇倾角、上下唇倾角数值减少，且自锁托槽组变化量大于金属托槽组。结论非拔牙矫治上颌轻中度拥挤时，随拥挤度增大，Damon Q自锁托槽对于软组织上唇突度的改变较3M金属托槽略大，在临床应用中要重视托槽及治疗体系的选择。
目的：比較Damon Q自鎖和3M金屬託槽非拔牙矯治輕中度上頜擁擠軟硬組織及牙弓變化的研究。方法選擇正畸矯治患者87例，以上頜擁擠程度和採用的矯治器種類分為Ⅰ度、Ⅱ度擁擠Damon Q自鎖託槽組（41例），Ⅰ度、Ⅱ度擁擠3M金屬託槽組（46例）。測量治療前後頭顱側位片及模型，整理數據採用配對t檢驗和成組t檢驗分析。結果非拔牙矯治上頜Ⅰ度、Ⅱ度擁擠時，兩種託槽治療後上頜牙弓寬度和牙弓長度均有增大，但2組間變化量差異無統計學意義。上頜Ⅱ度擁擠時，比較2組軟組織測量項目鼻脣角、上脣傾角、上下脣傾角數值減少，且自鎖託槽組變化量大于金屬託槽組。結論非拔牙矯治上頜輕中度擁擠時，隨擁擠度增大，Damon Q自鎖託槽對于軟組織上脣突度的改變較3M金屬託槽略大，在臨床應用中要重視託槽及治療體繫的選擇。

Objective To compare changes in dental arch and soft and hard tissue produced by the Damon Q self-ligating bracket and 3M metal bracket with non-extraction treatment in maxillary mild-to-moderate crowding cases. Meth-ods Eighty seven patients were selected in our study, who were assigned to 4 groups by the crowding degree of maxillary and appliance type:ⅠandⅡcrowding degree using Damon Q self-ligating bracket groups (41 cases);ⅠandⅡcrowding de-gree 3M metal bracket groups (46 cases). We measured lateral cephalometric radiographs and dental casts at both beginning and end of treatment. Paired t-tests and group t-tests were used in statistical analysis to compare the alteration in dental arch and soft and hard tissue. Results There was significant increase in width and length of maxillary dental arch by non-extraction treatment withⅠandⅡcrowding degree maxillary, but the results of both groups were not of statistical difference. To compare hard and soft tissue in two groups withⅡcrowding degree maxillary, the reduction of nasolabial angle, angle of inclination of upper lip, angle of upper lip and lower lip had obvious statistical significance and it is more prominent in self-ligating bracket group than in conventional bracket group. Conclusion Using non-extraction treatment, when maxillary crowding is moderate, ,Damon Q self-ligation bracket group result in more prominent changes of upper lip protrusion than 3M bracket with more marked crowding . Therefore, clinical doctors should pay more attention to choose bracket and treat-ment system for patients with marked crowding of maxillary dentition.
