【摘要】：研究背景 隨著口腔修復技術的發(fā)展和各種新材料的應用，缺失牙齒的修復在滿足功能的同時，在美學方面有了更高的要求。國內(nèi)外許多學者在美學修復（aestheticrestoration，AR）方面做了大量研究，但許多研究均是以左右對稱為前提的，但臨床中常見原有上頜前牙傾斜，扭轉(zhuǎn)等，因外傷或牙周疾病等原因?qū)е卵例X脫落需要進行修復治療者。此類就診者缺牙間隙的寬度與對側同名牙不同，但往往更希望能擁有排列整齊的牙齒，而不愿將修復體制作成原有形態(tài)。關于如何對此類患者進行修復，相關研究尚不多見。本研究希望通過不同人群對修復體與同名牙寬度不一致的認可程度，，來評估大眾對于此類修復的接受度，希望找出規(guī)律，為臨床治療提供參考。 目的：評價不同人群對于上頜中切牙修復體的寬度與同名牙不一致時的可接受度。 方法：拍攝個別正常牙合(individual normal occlusion,INO)者正面最大微笑照片，使用圖像處理軟件對所得圖片進行一側中切牙寬度拉伸，形成與對側同名牙不對稱的圖片。請被調(diào)查者查看圖片，分別指出發(fā)覺有中切牙差異的圖片，和可以接受的最大不對稱圖片，其最小值即為最小察覺值（the minimum perceived value，TMPV）,其最大值即為最大可接受值（the maximum acceptable values，TMAC）。對結果進行統(tǒng)計，并用x2檢驗對結果進行分析。 結果：共收到138份有效調(diào)查，其中口腔專業(yè)相關人員49人，非口腔專業(yè)相關人員89人。69.4%的口腔專業(yè)相關人員可以察覺出0.5mm的差異，而非口腔專業(yè)相關人員中只有30.3%的人可發(fā)覺此差異。44.9%的口腔專業(yè)相關人員可以最大容忍中切牙寬度相差1mm，而非口腔專業(yè)相關人員中，最大可以忍受中切牙寬度差距為1.5mm者，所占比例居多（39.3%）。 結論：在中切牙修復體寬度與對側同名牙不一致時，口腔專業(yè)相關人員比非口腔專業(yè)相關人員具有更敏銳的察覺力，年齡和性別的差異無明顯差別。非口腔專業(yè)相關人員對此類不對稱有著更大的容忍度。年齡大者比年輕者更能接受此類不對稱性修復。
[Abstract]:Background with the development of dental prosthesis technology and the application of various new materials, the restoration of missing teeth not only meets the function, but also has higher aesthetic requirements. Many scholars at home and abroad have done a great deal of research on aesthetic restoration (aestheticrestoration,AR), but many studies are based on the premise of left and right symmetry, but it is common in clinical practice to tilt and twist the original maxillary anterior teeth. Tooth loss due to trauma or periodontal disease. The width of the missing space is different from that of the contralateral teeth, but they prefer to have the teeth arranged neatly rather than to make the restoration system the original form. There are few studies on how to repair such patients. The purpose of this study is to evaluate the acceptance of the restoration by different people and to find out the rules for clinical treatment. Objective: to evaluate the acceptability of maxillary central incisor prosthesis in different population when the width of maxillary central incisor is not the same as that of the same name. Methods: individual normal (individual normal occlusion,INO) patients were photographed with the largest positive smile. The width of the middle incisor was stretched with image processing software to form the asymmetrical image of the contralateral teeth of the same name. The respondents were asked to look at the images and point out the images that found the difference between the central incisors and the acceptable maximum asymmetry images, the minimum value of which was the minimum perceived value (the minimum perceived value,TMPV). Its maximum value is the maximum acceptable value (the maximum acceptable values,TMAC). The results were analyzed by X 2 test. Results: a total of 138 effective surveys were received, of which 49 were related to stomatology and 89 were non-oral. 69.4% of them could detect the difference of 0.5mm. Only 30.3% of the non-oral related personnel could find the difference. 44.9% of the dental professionals could tolerate a difference of 1mm between the width of the incisor and the width of the incisor. The largest difference in the width of central incisor was 1.5mm (39.3%). Conclusion: when the width of the central incisor prosthesis is not the same as that of the contralateral tooth with the same name, the dental professionals are more sensitive to detection than the non-dental professionals, and there is no significant difference in age and sex. Non-oral professionals have greater tolerance for such asymmetries. Older people are more likely to accept such asymmetrical repair than young people.
