目的 探讨固定矫治器配合上切牙舌侧粘着式固定平导矫治深覆(牙合)患者的临床效果.方法 选择均角或低角Ⅲ度深覆(牙合)患者12例作为实验组,男6例,女6例,年龄12～30岁,平均17岁,拔牙9例,非拔牙3例.采用直丝弓固定矫正器治疗,配合制作上前牙舌侧粘着式固定平导辅助打开咬合.选择与实验组相匹配的12例患者作为对照组,对照组患者单纯使用固定矫正器治疗.当覆(牙合)打开后,制取模型,进行治疗前及咬合打开后模型测量分析,分析咬合打开量及所需时间.结果 模型测量结果显示:上颌舌侧固定平导辅助打开咬合效果明显,覆(牙合)平均减小3.37 mm,覆(牙合)打开的平均时间为3.75个月,明显短于对照组.结论 上切牙舌侧粘着式固定平导对于深覆(牙合)患者的矫治非常有效,而且制作简单,有利于口腔卫生,正畸治疗整个过程均不受影响,值得临床推广.
目的 探討固定矯治器配閤上切牙舌側粘著式固定平導矯治深覆(牙閤)患者的臨床效果.方法 選擇均角或低角Ⅲ度深覆(牙閤)患者12例作為實驗組,男6例,女6例,年齡12～30歲,平均17歲,拔牙9例,非拔牙3例.採用直絲弓固定矯正器治療,配閤製作上前牙舌側粘著式固定平導輔助打開咬閤.選擇與實驗組相匹配的12例患者作為對照組,對照組患者單純使用固定矯正器治療.噹覆(牙閤)打開後,製取模型,進行治療前及咬閤打開後模型測量分析,分析咬閤打開量及所需時間.結果 模型測量結果顯示:上頜舌側固定平導輔助打開咬閤效果明顯,覆(牙閤)平均減小3.37 mm,覆(牙閤)打開的平均時間為3.75箇月,明顯短于對照組.結論 上切牙舌側粘著式固定平導對于深覆(牙閤)患者的矯治非常有效,而且製作簡單,有利于口腔衛生,正畸治療整箇過程均不受影響,值得臨床推廣.

Objective To evaluate the bite opening effect of the fixed bite plate in the treatment of deep bite patients.Methods 12 deep bite patients with low or average mandibular plane angle were collected (6 male,6 female,12-30 years old,mean 17 years old) in experiment group.They received straight wire appliances with fixed bite plate.Another 12 matched patients were collected as control group to receive straight wire appliances only.Study models were taken before treatment and after the deep bite corrected.The overbite change was measured and the time needed for bite opening was calculated.Results Model analysis showed that overbite decreased significantly.The mean overbite reduction in the patients with fixed bite plate was 3.37 mm.The average time for bite opening was shorter significantly in the experimental group (average 3.75 months) than in the control group.Conclusions Fixed bite plate on the upper anterior teeth was effective on bite opening.It can be used throughout the treatment without interrupting the orthodontic procedures.
