目的 探讨头影测量和定量分析摆式矫治器加直丝弓技术在上颌第2磨牙萌出后的治疗效果.方法 选择安氏Ⅱ类错(牙合)患者,分为两组,第2磨牙未萌出者为对照组,第2磨牙完全萌出者为实验组.两组均戴用摆式矫治器,推磨牙向远中,当上下磨牙达到轻度安氏Ⅲ类关系时,维持3个月,拆除摆式矫治器.两组皆用滑动直丝弓技术进行第2期矫治,直至治疗结束.每位患者皆拍摄头颅侧位片.对患者的头颅侧位片进行测量、分析.结果 实验组的第1磨牙近中颊尖向远中移动4.62 mm,几何中心移动3.75 mm,约占第1磨牙远中移动量的81％.对照组的第1磨牙近中颊尖向远中移动5.78 mm,几何中心移动3.20 mm,约占第1磨牙远中移动量的55％,以上变化差异均具有显著的统计意义(P＜0.01).可见,两组的第1磨牙皆能有效地向远中移动,但实验组以整体移动为主,对照组以倾斜移动为主.结论 在上颌第2磨牙完全萌出的情况下,摆式矫治器仍可以有效远中移动第1、2磨牙.摆式矫治器加直丝弓技术仍可获得良好疗效.
目的 探討頭影測量和定量分析襬式矯治器加直絲弓技術在上頜第2磨牙萌齣後的治療效果.方法 選擇安氏Ⅱ類錯(牙閤)患者,分為兩組,第2磨牙未萌齣者為對照組,第2磨牙完全萌齣者為實驗組.兩組均戴用襬式矯治器,推磨牙嚮遠中,噹上下磨牙達到輕度安氏Ⅲ類關繫時,維持3箇月,拆除襬式矯治器.兩組皆用滑動直絲弓技術進行第2期矯治,直至治療結束.每位患者皆拍攝頭顱側位片.對患者的頭顱側位片進行測量、分析.結果 實驗組的第1磨牙近中頰尖嚮遠中移動4.62 mm,幾何中心移動3.75 mm,約佔第1磨牙遠中移動量的81％.對照組的第1磨牙近中頰尖嚮遠中移動5.78 mm,幾何中心移動3.20 mm,約佔第1磨牙遠中移動量的55％,以上變化差異均具有顯著的統計意義(P＜0.01).可見,兩組的第1磨牙皆能有效地嚮遠中移動,但實驗組以整體移動為主,對照組以傾斜移動為主.結論 在上頜第2磨牙完全萌齣的情況下,襬式矯治器仍可以有效遠中移動第1、2磨牙.襬式矯治器加直絲弓技術仍可穫得良好療效.

Objective To investigate the clinical effect of pendulum and straight wire technology in patients with fully erupted second molar.Methods Patients with Angle class Ⅱ malocclusion were chosen.Control group included patients without erupted second molar.Experimental group included patients with completely erupted second molar.Pendulums were used in two groups to distalize maxillary molars.Then straight wire orthodontic treatment had been performed until treatment was over.Cephalograms of each stage were analyzed.Results In the experimental group,mesiobuccal cusp of first molar was distalized for 4.62 mm,geometric center was distalized for 3.75 mm,about 81 percent of the movement of mesiobuccal cusp.In control group,mesiobuccal cusp of first molar was dis talized for 5.78 mm,geometric center was distalized for 3.20 mm,about 55 percent of the movement of mesiobuccal cusp.It turned out first molar was distalized in both groups,but more rotation took place in control group than that in the experimental group.Conclusions Pendulum can distalize maxillary first and second molars in patients with completely erupted second molar.The pendulum and straight wire technology can treat these patients successfully.
