【摘要】 目的:探討微螺釘支抗種植體在口腔正畸中的效果。方法:選取筆者所在醫院2014年2月-2017年2月收治的錯畸形患者96例,分為對照組48例和研究組48例。對照組應用一般加強支抗,研究組應用微螺釘支抗種植體。結果:研究組顯效41例,有效5例,無效2例,總有效率為95.8%,對照組顯效30例,有效8例,無效10例,總有效率為81.2%,兩組比較,差異有統計學意義(P<0.05)。治療后研究組的上中切牙凸距差高于對照組,磨牙位移顯著低于對照組,上中切牙傾角差顯著高于對照組,差異有統計學意義(P<0.05)。經過治療后研究組無種植體脫落或松動情況出現,所有患者均前牙正常覆合覆蓋,發生牙齦腫痛及感染者2例,并發癥發生率為4.16%;對照組患者在治療中口外加強支抗脫落2例,口腔內橫腭支抗脫落3例,牙齦紅腫感染者4例,因不配合佩戴放棄治療者1例,并發癥發生率為20.83%。兩組比較差異有統計學意義(字2=6.095,P<0.05)。結論:微螺釘支抗種植體在口腔正畸中效果顯著,因此應該被更廣泛地應用于口腔正畸。

Studys on the Effect of Micro-screw Implantation in Oral Orthodontic Treatment/HE Xiao-fang,HUANG Min,ZHAO Qin-wen.//Chinese and Foreign Medical Research,2017,15(29):1-3
【Abstract】 Objective:To investigate the effect of micro-screw implantation in oral orthodontic treatment.Method:In our hospital from February 2014 to February 2017,96 patients with oral orthodontic were randomly divided into the control group of 48 cases and 48 cases of the research group.The control group used general method and the research group used micro-screw implantation.Result:In the research group,41 cases were markedly effective,5 cases was effective,and 2 cases was ineffective,the total effective rate was 95.8%,in the control group was markedly effective in 30 cases,effective in 8 cases,ineffective in 10 cases,the total effective rate was 81.2%,the difference was statistically significant(P<0.05).After treatment,the molar displacement of the research group was significantly lower than that of the control group,and the difference of the upper and middle incisors and the maxillary incisors were significantly higher than those of the control group,the differences were statistically significant(P<0.05).After treatment the research group had no implant failure or loosening occurs,all patients had normal anterior overbite and overjet,gingival swelling and infection occurred in 2 cases,the complication rate was 4.16%;the control group in the treatment of patients with extraoral anchorage strengthening off 2 cases,oral palatal anchorage loss in 3 cases,4 cases of gingival swelling infection,due to inappropriate wear give up treatment in 1 case, the complication rate was 20.83%,the complication rate was statistically significant difference between the two groups(字2=6.095,P<0.05).Conclusion:The application of micro-screw implant anchorage in orthodontic treatment is significant,so it shall be widely used in orthodontics.endprint

錯畸形是指由先天的遺傳因素或后天的環境因素,如疾病、口腔不良習慣、外傷、牙周病等原因造成的牙齒排列不整齊、頜骨大小形態位置的異常、面部畸形等。據報道,錯畸形的患病率高達百分之五十以上[1]。錯畸形不僅影響頜骨的發育,影響容貌外觀,還影響口腔健康和功能。因此,隨著人們生活水平地逐漸提高,越來越多的人選擇口腔正畸治療。正畸治療主要是通過各種矯正裝置來調整面部骨骼、牙齒及頜面部神經肌肉之間的協調性[2]。口腔正畸技術也得到了快速發展。本文研究了微螺釘支抗種植體在口腔正畸中的臨床效果,現報道如下。
1 資料與方法
1.1 一般資料
選取筆者所在醫院2014年2月-2017年2月收治的錯畸形患者96例,按隨機數字表法分為對照組48例和研究組48例。對照組男24例,女24例,年齡16~25歲,平均(20.82±0.24)歲。研究組男26例,女22例,年齡18~27歲,平均(22.16±0.57)歲。兩組患者均符合WHO錯畸形診斷標準。兩組患者性別、年齡、臨床癥狀等一般資料比較差異無統計學意義(P>0.05)。……p>
