非贵金属与贵金属烧瓷冠在老年口腔修复中的应用效果比较

Application effect comparison of non-precious metal and precious metal porcelain crowns in the elderly oral repair

目的探讨非贵金属与贵金属烧瓷冠在老年口腔修复中的应用效果。方法回顾性分析我院2013年1月~2014年12月收治的184例老年口腔修复患者临床资料,按照烧瓷冠材料分为非贵金属组(n=119例)及贵金属组(n=65例)。非贵金属组采用镍铬合金烧瓷冠修复,贵金属组采用金铂合金烧瓷冠修复。比较两组患者烧瓷冠修复终末随访时的满意度及烧瓷冠修复3、6个月的改良菌斑指数分级情况。结果贵金属组患者的烤瓷冠颜色(95.4%)、边缘密合度(96.9%)、颈缘染色(98.5%)、牙龈情况(92.3%)、修复体外型(98.5%)的满意度均显著高于非贵金属组(84.9%、85.6%、79.8%、80.7%、78.2%),差异均有统计学意义(P<0.05)。贵金属组种植体植入3个月的改良菌斑指数分级情况[A级18例,B级23例,C级10例,D级14例]显著优于非贵金属组[A级21例,B级28例,C级38例,D级32例],植入6个月的改良菌斑指数分级情况[A级18例,B级21例,C级7例,D级19例]显著优于非贵金属组[A级15例,B级19例,C级38例,D级47例],差异均有统计学意义(P<0.05)。结论贵金属烧瓷冠在老年口腔种植修复中与非贵金属烧瓷冠比较,在生物相容性、美学方面的优势明显,且种植修复后利于种植体牙周的健康。

Objective To explore the application efect of non-precious metal and precious metal porcelain crowns in the elderly oral repair. Methods The clinical data of 184 elderly patients given with oral repair admitted into our hospital from January 2013 to December 2014 were retrospectively analyzed. All patients were divided into the non-precious metal group（n=119 cases） and precious metal group（n=65 cases）according to the different ceramic crown material. The non-precious metal group was given repair of nicochrome, while the precious metal group was given repair of platino.Satisfaction degree at the end-of-follow-up of porcelain-fused-to-metal crowns and improved plaque index grading at3 and 6 months after porcelain-fused-to-metal crowns were compared between the two groups. Results The satisfaction degree of porcelain crown color（95.4%）, marginal compatibility（96.9%）, neck margin staining（98.5%）, gingival condition（92.3%）, and repair body type（98.5%） in patients of the precious metal group was significantly higher than that of the non-precious metal group（84.9%, 85.6%, 79.8%, 80.7%, 78.2%） respectively, and the differences were statistically significant（P〈0.05）. The grading of the improved plaque index in the precious metal group（grade A：18 cases, grade B：23 cases, grade C：10 cases, grade D：14 cases） after implantation for 3 months was significantly better than that in the non precious metal group（grade A：21 cases, grade B：28 cases, grade C：38 cases, grade D：32 cases）, and the grading of the improved plaque index in the precious metal group（grade A：18 cases, grade B：21 cases, grade C：7 cases, grade D：19 cases） after implantation for 6 months was significantly better than that in the non precious metal group（grade A：15 cases, grade B：19 cases, grade C：38 cases, grade D：47 cases） and the differences were statistically significant（P〈0.05）. Conclusion In the elderly dental implant restoration, the precious metal porcelain crown has a significant advantage compared with non precious metal porcelain crown in biocompatibility and aesthetics, and it is beneficial to the periodontal health of the implant. after planting and repairing.
