摘　　要：背景:近年来,临床上应用的以烤瓷材料为全冠的种类较多,不同烤瓷基底材料对基牙牙周组织造成的不利影响逐渐显露,修复后出现的牙龈红肿、出血等牙周组织炎症问题越来越受到重视。目的:观察镍铬合金烤瓷、贵金属烤瓷和金沉积烤瓷冠3种不同烤瓷材料冠桥修复体对基牙牙周组织的影响。方法:根据患者意愿对78例患者的254颗牙分别制作镍铬合金烤瓷、贵金属烤瓷和金沉积烤瓷冠,修复后1年进行复查,临床对比检查修复前后牙龈颜色、牙龈出血指数、菌斑指数、牙周探诊深度的变化。结果与结论:镍铬合金烤瓷冠修复1年后有21颗牙龈发生变色,贵金属烤瓷和金沉积烤瓷冠对牙龈色泽影响很少或没有;镍铬合金烤瓷、贵金属烤瓷后牙龈出血指数与术前比较差异有显著性意义,而金沉积烤瓷修复后牙龈出血指数与术前比较差异无显著性意义;3组术前、术后的菌斑指数、牙周探诊深度无明显差异。结果提示3种修复体中金沉积烤瓷冠修复对牙周组织的影响最小,贵金属烤瓷冠次之,镍铬合金烤瓷冠对牙周组织的影响最大。BACKGROUND：In recent years,porcelain materials applied in clinical practice are mainly complete crown,different kinds of porcelain substrate materials exhibiting adverse effect on the periodontium of abutment teeth has been attracting more and more attention,some periodontal inflammation problems such as gingival swelling and bleeding are becoming a focus.OBJECTIVE：To evaluate the effect of three kinds of porcelain fused to metal crowns,including Ni-Cr alloy,precious metal and galvanized forming crowns/bridges,on periodontal health.METHODS：According to the aspiration of the patient,254 teeth from 78 patients were respectively restored by Ni-Cr alloy,precious metal and galvanized forming crowns/bridges.Follow-up visits were performed at one year postoperation,to compare the gingival color,sulcus bleeding index,plaque index and the change of periodontal probing depth.RESULTS AND CONCLUSION：After 1 year,21 teeth restored by Ni-Cr alloy porcelain fused to metal crowns showed the change of gingival color,but the effect of precious metal porcelain fused to metal crowns and galvanized forming crowns/bridges was little or no on gingival color.Cases restored by Ni-Cr alloy porcelain fused to metal crowns/bridges and precious metal crowns/bridges showed significant difference in sulcus bleeding index between pre-and post-restoration,while galvanized forming crowns showed no significant difference.There are no significant difference in three groups of the plaque index and periodontal probing depth between pre-and post-restoration.Results demonstrated that galvanized forming crowns/bridges have minimal effect on the health of periodontal tissue,then precious metal crowns/bridges,and Ni-Cr alloy porcelain fused to metal crowns/bridges maximal.
