目的 研究拔除下颌第三磨牙后用种植体支抗远移下颌磨牙,矫治恒牙期骨性Ⅲ类错(牙合)畸形的临床疗效.方法 选择15例恒牙期骨性Ⅲ类错(牙合)畸形患者,平均(24.0±5.8)岁.患者凹面型、前牙反(牙合)、第一磨牙近中关系,拔除下颌第三磨牙后,应用种植体支抗推下颌磨牙向远中移动,并结合MBT直丝弓矫治技术进行非手术掩饰性矫治.对矫治前后头颅侧位X线片进行头影测量分析.结果 矫治后所有患者第一磨牙、尖牙关系达到中性,前牙区反(牙合)解除,软组织侧貌得到改善;且与矫治前相比,矫治后ANB角增加1.65°±1.04°,Wits值增加(4.39±1.93) mm,上下齿槽座角(AB-NP角)增加3.20°±1.61°,Sn-Pg'审美线距差增加(1.13±0.99) mm,矫治前后差异有统计学意义(P＜0.05).结论 减数下颌第三磨牙,应用种植体支抗推下颌磨牙远移,结合直丝弓固定矫治技术矫治恒牙期骨性Ⅲ类错(牙合)畸形,可取得理想的咬合关系,并使软组织侧貌得到改善.
目的 研究拔除下頜第三磨牙後用種植體支抗遠移下頜磨牙,矯治恆牙期骨性Ⅲ類錯(牙閤)畸形的臨床療效.方法 選擇15例恆牙期骨性Ⅲ類錯(牙閤)畸形患者,平均(24.0±5.8)歲.患者凹麵型、前牙反(牙閤)、第一磨牙近中關繫,拔除下頜第三磨牙後,應用種植體支抗推下頜磨牙嚮遠中移動,併結閤MBT直絲弓矯治技術進行非手術掩飾性矯治.對矯治前後頭顱側位X線片進行頭影測量分析.結果 矯治後所有患者第一磨牙、尖牙關繫達到中性,前牙區反(牙閤)解除,軟組織側貌得到改善;且與矯治前相比,矯治後ANB角增加1.65°±1.04°,Wits值增加(4.39±1.93) mm,上下齒槽座角(AB-NP角)增加3.20°±1.61°,Sn-Pg'審美線距差增加(1.13±0.99) mm,矯治前後差異有統計學意義(P＜0.05).結論 減數下頜第三磨牙,應用種植體支抗推下頜磨牙遠移,結閤直絲弓固定矯治技術矯治恆牙期骨性Ⅲ類錯(牙閤)畸形,可取得理想的咬閤關繫,併使軟組織側貌得到改善.

Objective To evaluate the outcome of patients with skeletal Class Ⅲ malocclusion treated with extraction of mandibular third molars and distalization of molars using implant anchorage combined with MBT appliance.Methods Fifteen patients(mean age 24.0 ± 5.8) with skeletal Class Ⅲ malocclusion were selected.The mandibular third molars were extracted and the mandibular molars were moved distally using implant combined with MBT appliance.Cephalometric analysis was carried out before and after treatment.Results After active treatment,ANB,Wits distance,AB-NP and the distance between upper and lower lip position to SnPg' increased by 1.65°± 1.04°,(4.39± 1.93) mm,3.20°± 1.61° and (1.13±0.99) mm,respectively.The differences were statistically significant(P ＜ 0.05).Conclusions The skeletal Class Ⅲ patients in the permanent dentition could be treated successfully with extraction of mandibular third molars and distalization of mandibular molars using implant anchorage combined with MBT appliance.The soft-tissue profile was improved.
