目的 探讨应用Incognito个体化舌侧矫正系统进行拔牙矫治的早期临床效应.方法 选取19例(8名男性,11名女性,年龄12-23岁)安氏Ⅱ1类(包括亚类),毛氏Ⅱ2+Ⅳ1+Ⅰ1类患者,减数四颗前磨牙,使用Incognito个体化舌侧矫正系统进行矫治.采用Wilcoxon符号秩检验法,对治疗前和排齐整平结束时的X线头影测量和模型测量变化进行对比研究.结果 X线头影测量结果显示:排齐后,U1/SN减少7.70°,U1/NA减少7.94°,U1-NA减少2.85mm,L1/NB减少4.60°,L1-NB减少1.8mm,MP/SN增加1.52°,L6-MP距增加0.51mm、L1-MP距减小1.29mm、OB减小1.18mm,且差异均有显著性(P＜0.05).模型测量结果示:上、下颌尖牙间宽度分别增加2.39mm和2.60mm,下颌第一磨牙间宽度增加1.26mm,上颌全牙弓长减小2.42mm,spee曲线曲度减小1.11mm,且差异均具显著性(P＜0.05).结论 应用Incognito个体化舌侧矫正器进行拔牙矫治,早在舌侧矫治的排齐阶段就已经出现明显的切牙的内收、下切牙压低、磨牙伸长、下颌后旋、和牙弓宽度的增加.该研究提示我们,对于低角深覆(牙合)病例,舌侧矫治有助于在早期打开咬(牙合),整平深spee曲线,改善侧貌.但对于高角深覆(牙合)和前牙牙轴较直的病例,从舌侧矫治初期即要针对可能产生的不利变化进行积极的处理.
目的 探討應用Incognito箇體化舌側矯正繫統進行拔牙矯治的早期臨床效應.方法 選取19例(8名男性,11名女性,年齡12-23歲)安氏Ⅱ1類(包括亞類),毛氏Ⅱ2+Ⅳ1+Ⅰ1類患者,減數四顆前磨牙,使用Incognito箇體化舌側矯正繫統進行矯治.採用Wilcoxon符號秩檢驗法,對治療前和排齊整平結束時的X線頭影測量和模型測量變化進行對比研究.結果 X線頭影測量結果顯示:排齊後,U1/SN減少7.70°,U1/NA減少7.94°,U1-NA減少2.85mm,L1/NB減少4.60°,L1-NB減少1.8mm,MP/SN增加1.52°,L6-MP距增加0.51mm、L1-MP距減小1.29mm、OB減小1.18mm,且差異均有顯著性(P＜0.05).模型測量結果示:上、下頜尖牙間寬度分彆增加2.39mm和2.60mm,下頜第一磨牙間寬度增加1.26mm,上頜全牙弓長減小2.42mm,spee麯線麯度減小1.11mm,且差異均具顯著性(P＜0.05).結論 應用Incognito箇體化舌側矯正器進行拔牙矯治,早在舌側矯治的排齊階段就已經齣現明顯的切牙的內收、下切牙壓低、磨牙伸長、下頜後鏇、和牙弓寬度的增加.該研究提示我們,對于低角深覆(牙閤)病例,舌側矯治有助于在早期打開咬(牙閤),整平深spee麯線,改善側貌.但對于高角深覆(牙閤)和前牙牙軸較直的病例,從舌側矯治初期即要針對可能產生的不利變化進行積極的處理.

Objective The aim is to reveal the dentofacial changes of Angle Ⅱ1 cases during alignment phase using Incognito lingual orthodontic appliance. Methods Nineteen patients (8 Male and 11 female, aging from 12y to 23y) with Angle Ⅱ1 malocclusion were selected for lingual orthodontic treatment with four premolars extraction. Customized lingual orthodontic appliance (IncognitoTM) was used. Cephalometric radiographs and alginate impressions were taken before treatment and at the end of alignment. The comparison between pre-treatment and post-alignment were analyzed by Paired-Sample Wilcoxon Signed Rank Test through SPSS Statistical Package.Results From the Cephalometric analysis, the following changes were found significantly different (P＜0.05). U1/SN decreased 7.70°. U1/NA decreased 7.94°with 2.85 mr. L1/NB decreased 4.60°with 1.8mm. MP/SN increased 1.52°. L6-MP increased 0.51 mm. L1-MP decreased 1.29mm. OB decreased 1.18mm. From the model analysis, the following changes with significant differences were demonstrated. Upper and lower intercanine widths and lower intermolar widths increased 2.39mm,2.60mm and 1.26mm respectively. Upper arch depth from molar to incisor decreased 2.42mm. The curve of spee became shallow by 1.11mm. Conclusion During alignment phase, the upper and lower incisors tipped lingually with profile improved. The overbite decreased with lower incisors intruded, and the lower molars extruded with mandibular plane angle increased. It implied that lingual appliance would be helpful for lower angle cases with deep overbite, and cautions should be taken from the initial phase during lingual orthodontic treatment in high angle cases.
