樹脂分層修復與全瓷修復體在前牙缺損修復中的應用比較

[摘要]目的：探討復合樹脂分層前牙修復與全瓷修復體在前牙缺損修復中的效果及美學價值。方法：采用病例對照研究，選取2021年3月-2023年3月西安交通大學口腔醫院口腔綜合科收治的120例前牙牙體缺損患者作為研究對象，隨機將其分為A組和B組，每組60例。A組患者采用復合樹脂分層修復前牙，B組患者采用全瓷修復體修復前牙缺損，對比兩組患者修復后6個月、12個月的美學效果，牙齦出血指數、牙周探診深度及齦下菌斑標本病原菌檢出率的差異。結果：治療后6個月、12個月，B組患者的邊緣適合性、顏色匹配效果、修復體固位效果、修復體邊緣染色、牙齦健康程度按照USPHS評分標準為A級的患者占比顯著高于A組（P＜0.05）；治療后6個月、12個月，B組患者的牙齦出血指數及牙周探診深度均低于A組（P＜0.05）；治療后12個月，B組患者的齦下菌斑中的中間普菌、福賽坦菌檢出率與A組患者比較，差異無統計學意義（P＞0.05）；B組的牙齦卟啉單胞菌、具核梭形桿菌、伴放線放線桿菌檢出率均低于A組，差異均有統計學意義（P＜0.05）；治療后12個月，B組患者治療效果總體優于A組（P＜0.05）。結論：復合樹脂分層修復與全瓷修復體在前牙缺損修復后均能取得較好的效果，但是全瓷修復體更有利于提升修復的美學效果，降低修復后的牙周損害，總體效果更好。

Abstract： Objective" Exploring the effects and aesthetic value of composite resin layered anterior tooth restoration and all ceramic restoration after anterior tooth defect repair. Methods" Using a case-control study， 120 patients with anterior tooth defects admitted to the dental outpatient department of Hospital of Stomatology， Xi 'an Jiaotong University from March 2021 to March 2023 were selected as the study subjects. They were randomly divided into Group A and Group B， with 60 patients in each group. Group A patients received composite resin layered anterior tooth restoration， while Group B received all ceramic restoration for anterior tooth defects. The aesthetic effects of the two groups of patients at 6 and 12 months after restoration were compared Differences in gingival bleeding index， periodontal probing depth， and pathogen detection rate in subgingival plaque specimens. Results" After 6 and 12 months of treatment， the proportion of patients in Group B with marginal fitness， color matching effect， restoration fixation effect， restoration edge staining， and gingival health grade A according to the USPHS scoring standard was significantly higher than that in Group A， and the difference was statistically significant （P＜0.05）. After 6 and 12 months of treatment， the gingival bleeding index and periodontal probing depth of Group B patients were lower than those of Group A patients， and the differences were statistically significant （P＜0.05）. After 12 months of treatment， the detection rates of prevotella intermedia and Forsythiaceae in the subgingival plaque of Group B patients were not statistically significant compared to Group A patients （P＞0.05）. The detection rates of Porphyromonas gingivalis， Fusobacterium nucleatum， and Actinobacterium actinomycetes in Group B were lower than those in Group A， and the differences were statistically significant （P＜0.05）. After 12 months of treatment， the overall effect of Group B was better than Group A （P＜0.05）. Conclusion" Both composite resin layered anterior tooth restoration and all ceramic restoration can achieve good results after anterior tooth defect restoration， but all ceramic restoration is more conducive to improving the aesthetic effect of restoration， reducing periodontal damage after restoration， and overall achieving better results.
