目的 探讨应用微种植体支抗治疗安氏Ⅱ类1分类错牙争畸形临床疗效及治疗方法临床要点.方法 对2005-2008年在山东省济宁口腔医院就诊的安氏Ⅱ类1分类上颌前突或伴轻微下颌后缩的正畸患者11例,采用MBT(滑动)直丝弓矫治技术,进行减数双尖牙矫治.黏结矫治器之前在上颌双侧第二双尖牙和第一磨牙之间的频侧分别植入微种植体,在治疗早期应用自攻型微种植体进行尖牙向远中牵引,并在更换至稳定弓丝后利用微种植体整体内收前牙,牵引力值为1.5～2.0N,平均治疗时间为19个月,治疗结束观察1年.于治疗前后拍摄头颅侧位片.进行头影测量分析.结果 11例患者除1例种植体松动脱落,其余患者第一磨牙在前后向和垂直向均未发生显著性移动,患者的颜面侧貌得到明显改善,取得较为满意的治疗效果.与治疗前相比,治疗后SNA、ANB、FH to U1、IMPA角明显减小,差异均具有统计学意义;SNB角略有增大,FMA略有减小,但差异无统计学意义.结论微种植体支抗能够有效治疗安氏Ⅱ类1分类患者,并达到磨牙强支抗的效果.
目的 探討應用微種植體支抗治療安氏Ⅱ類1分類錯牙爭畸形臨床療效及治療方法臨床要點.方法 對2005-2008年在山東省濟寧口腔醫院就診的安氏Ⅱ類1分類上頜前突或伴輕微下頜後縮的正畸患者11例,採用MBT(滑動)直絲弓矯治技術,進行減數雙尖牙矯治.黏結矯治器之前在上頜雙側第二雙尖牙和第一磨牙之間的頻側分彆植入微種植體,在治療早期應用自攻型微種植體進行尖牙嚮遠中牽引,併在更換至穩定弓絲後利用微種植體整體內收前牙,牽引力值為1.5～2.0N,平均治療時間為19箇月,治療結束觀察1年.于治療前後拍攝頭顱側位片.進行頭影測量分析.結果 11例患者除1例種植體鬆動脫落,其餘患者第一磨牙在前後嚮和垂直嚮均未髮生顯著性移動,患者的顏麵側貌得到明顯改善,取得較為滿意的治療效果.與治療前相比,治療後SNA、ANB、FH to U1、IMPA角明顯減小,差異均具有統計學意義;SNB角略有增大,FMA略有減小,但差異無統計學意義.結論微種植體支抗能夠有效治療安氏Ⅱ類1分類患者,併達到磨牙彊支抗的效果.

Objective The purpose of this study was to evaluate the treatment results and clinical treatment method of Angel' s Class Ⅱ1 malocclusion cases by the application of microscrews anchorage. Methods The study comprised 11patients from Orthodontic Department of Jining Stomatology Hospital from the year 2005 to 2008. All the patients pre-sented with maxillary protrusion or little mandible intrusion treated with MBT straight wire appliance by extraction of premolars. Self-drilling microscrews were impanted in the bilateral buccal alveolar bone between the maxillary first mo-lars and second premolar before bonding straight wire appliance.Upper canines were ligated backward to the microacrews in the initial treatment.When the main arch was stable enough, the frontal teeth were retracted together with the micro-screws anchorage 1.5 to 2N force each side was added to microscrews and retracted teeth. The average treatment time was 19 months, and follow-up lasted 1 year after the treatment .The cephalometric films before and after the treatment were measured and compared. Results Angel's Class Ⅱ1 malocclusion in 11 patients were corrected effectively, ex-cept for 1 failure case. First molars had no significant changes in anteroposterior and vertical directions. Patients' facial profile had been improved greatly. After the treatment, SNA, ANB, FH to U1 and IMPA angle decreased significantly.Furthermore SNB increased a little , but FMA decreased a little. Neither of them had significant changes. Conclusion Angel' s ClassⅡ1 malocclusion can be treated effectively by microscrew anchorage, with no loss of molar anchorage.
