摘要
目的对比分析二氧化锆全瓷冠与钴铬合金烤瓷冠修复牙体牙列缺损的临床疗效。方法选择2008年3月以来广东工业大学医院口腔科和江西省萍乡市安源区现代口腔门诊部牙体牙列缺损全冠修复患者150例364颗,随机分为2组,实验组采用二氧化锆全瓷冠75例185颗,对照组采用钴铬合金烤瓷冠75例179颗,修复后随访2年对比观察,结果采用χ2检验分析。结果两组在修复体完整性、固位、边缘密合度、牙敏感症状、继发龋、邻面接触点、过敏反应方面差异无统计学意义(P>0.05);但在牙龈状况、龈缘着色、颜色匹配方面差异有统计学意义(P<0.01)。结论二氧化锆全瓷冠修复体美学效果和生物相容性优于钴铬合金烤瓷冠。
Objective To compare and analyze the clinical effects of restoring tooth dentition defect by using zirconium dioxide full porcelain crowns and cobalt chromium alloy porcelain crowns. Methods 150 patients with 364 teeth suffering from tooth dentition defect in hospital of guangdong university of technology and modem stomatology clinic in pingxiang since March of 2008 are chosen and randomly divided into two groups. 75 patients with 185 teeth in the experimental group are restored with zirconium dioxide full porcelain crowns and 75 patients with 179 teeth in the control group are restored with cobalt chromium alloy porcelain crowns, which was followed up with 2-year observation. Results There is no statistical significance between the two groups in terms of repair integrity, retention, edge adaptation, tooth sensitivity symptoms, secondary caries, contact points, and allergic reaction （ P 〉 0. 05 ） . But statistical significance exists in gingival status, gingival coloration, and color matching （ P 〈 0. 01 ） . Conclusion Zirconium dioxide full porcelain crowns are superior to cobalt chromium alloy porcelain crowns in aesthetic effect and biocompatibility.
