摘要
背景:可摘局部义齿卡环可对口腔微生态系造成一定影响。目的:从卡环材料、形态、与基牙接触面积等方面阐述可摘局部义齿卡环对口腔微生态系的影响。方法:应用计算机检索1980至2011年PubMed数据库、万方数据库、维普数据库、CNKI数据库、OVID数据库中与卡环对硬组织,软组织及唾液微生物影响的研究密切相关的文章。结果与结论:可摘局部义齿由人工牙,基托,牙合支托,固位体和连接体组成,它的戴入可对口腔微生态系造成一定影响。卡环是可摘局部义齿最直接的固位体,它主要与基牙的颊舌面相接触,影响其所在基牙颊舌面的生理性自洁作用,促进菌斑在卡环与基牙接触区周围的聚集,还可改变菌斑和龈沟中细菌的数量和种类,影响其所在基牙颊舌面和牙周微生态系,在一定条件下可导致龋病,牙龈炎,牙周病的发生。
BACKGROUND：The clasps of removable partial denture can influence the oral ecosystem. OBJECTIVE：To show the effects of the clasps of removable partial denture on the oral ecosystem from the aspects of materials, shape and contact area with the abutment. METHODS：We selected articles about the influences of clasp on microorganisms of hard tissue, soft tissue and saliva ecosystem by searching PubMed database, Wanfang database, VIP database, CNKI database and OVID database from 1980 to 2011. RESULTS AND CONCLUSION：Removable partial denture is composed of artificial teeth, denture base, occlusal rest, retainer and connector. However, it can influence the oral microecosystem. Clasp, the direct retainer of the removable partial denture, contacting with the buccal and lingual surface of the tooth, can not only improve the capacity of oral physiological clean to promote the aggregation of dental plaque but alter the quantity and type of bacterium in plaque and gingival sulcus. In certain conditions, this can lead to caries, gingivitis and periodontal diseases.
