【摘要】：[目的]牙齦退縮是指牙齦緣向釉牙骨質(zhì)界的根方退縮而致使的牙根暴露，可造成牙本質(zhì)敏感、根面磨損和根面齲的發(fā)生，并嚴(yán)重影響顏面美觀。牙齦退縮的發(fā)生并非由單一病因引起，目前認(rèn)為其致病因素是多因子共同作用的結(jié)果，包括病理因素、解剖因素、牙齒位置異常、醫(yī)源性損傷、牙合創(chuàng)傷和生活中的不良習(xí)慣等。牙齦退縮的分類(lèi)有很多種，其中臨床最常使用的分類(lèi)方法是1985年由Miller提出的分度法，此方法能很好地用來(lái)評(píng)價(jià)術(shù)后療效。臨床上針對(duì)牙齦退縮的治療方法有很多，正畸治療則是其中之一，但是，對(duì)于正畸治療是否會(huì)改善牙齦退縮或引起、加重牙齦退縮，至今尚無(wú)一致的觀點(diǎn)。有一部分學(xué)者通過(guò)臨床研究和動(dòng)物實(shí)驗(yàn)探索發(fā)現(xiàn)，正確的正畸治療方法能夠有助于改善牙齦退縮，而更多學(xué)者則認(rèn)為正畸治療會(huì)引起或加重牙齦退縮。嚴(yán)重的牙齦退縮，正畸治療很難使牙齦完全再生，因此，需要根據(jù)情況在正畸治療前后行牙周手術(shù)擴(kuò)增附著齦，以更好改善牙齦美觀。 [方法]報(bào)告2例牙周病伴牙齦退縮的正畸臨床典型病例，根據(jù)病史和臨床檢查分析患者的病因，判斷患者待解決的問(wèn)題，以及給予患者制定合適的矯治方案，患者的矯治過(guò)程在牙周科積極配合下完成，全程使用輕力，采用間斷力及延長(zhǎng)復(fù)診時(shí)間，片切前牙鄰面，控制牙根轉(zhuǎn)矩，解決擁擠及反牙合，排齊牙列，去除牙合干擾，平均療程16個(gè)月，透明壓模保持器保持。 [結(jié)果]患者牙列排列整齊，前牙覆牙合覆蓋基本正常，無(wú)創(chuàng)傷牙合，牙周病得到很好地控制，牙齦退縮有明顯改善，達(dá)到預(yù)期的矯治目標(biāo)。 [結(jié)論]通過(guò)2例典型臨床病例報(bào)告及文獻(xiàn)回顧，，探討了牙齦退縮的病因和分類(lèi)，以及正畸治療對(duì)牙齦退縮的影響。正確的診斷，完善的矯治計(jì)劃，細(xì)絲輕力的應(yīng)用，以及貫穿始終的牙周治療是矯治成功的關(guān)鍵，正畸治療在一定程度上可以對(duì)牙齦退縮起到積極的作用。
[Abstract]:[objective] gingival retraction refers to the root exposure caused by the gingival margin retreating to the root side of the enamel bone, which can cause dentin sensitivity, root surface wear and root surface caries. The occurrence of gingival retraction is not caused by a single cause. At present, it is considered that the cause of gingival retraction is the result of the combined action of many factors, including pathological factors, anatomical factors, abnormal position of teeth, iatrogenic injury. There are many kinds of classification of gingival retraction, among which the most commonly used classification method in clinic is the graduation method proposed by Miller in 1985. This method can be used to evaluate the effect of gingival retraction. There are many clinical methods for gingival retraction, and orthodontic treatment is one of them. However, if orthodontic treatment can improve or cause gingival withdrawal, it will aggravate gingival withdrawal. So far, there is no consensus. Some scholars have found that correct orthodontic treatment can help to improve gingival retraction through clinical research and animal experiments. However, more scholars believe that orthodontic treatment can cause or aggravate gingival withdrawal. Serious gingival retraction is very difficult for orthodontic treatment, so it is necessary to perform periodontal surgery before and after orthodontic treatment to expand the adherent gingiva according to the situation. To better improve the beauty of the gums. [methods] two typical orthodontic cases of periodontal disease with gingival retraction were reported. According to the history and clinical examination, the etiology of the patients was analyzed, the problems to be solved were judged, and the appropriate treatment plan was made. The correction process of the patients was completed with the active cooperation of periodontal department. The whole process used light force, used discontinuous force and extended the time of re-diagnosis, cut the adjacent surface of the anterior teeth, controlled the root torque, solved the crowding and reverse occlusion, arranged the dentition, and removed the occlusion interference. The average course of treatment was 16 months, and the transparent die holder was maintained. [results] the teeth of the patients were arranged neatly, the overbite of the anterior teeth was basically normal, the periodontal disease was well controlled, the gingival retraction was obviously improved, and the expected correction goal was achieved. [conclusion] the etiology and classification of gingival retraction and the effect of orthodontic treatment on gingival retraction were discussed through the reports of 2 typical clinical cases and literature review. Orthodontic treatment can play a positive role in gingival retraction to some extent.
