钛金属烤瓷修复的临床性能评价

Clinical Evaluation of the Titanium Metal Porcelain Restoration

目的 :评价钛金属烤瓷修复体的临床性能。方法 :将 87例患者分为两组 ,试验组 4 2例患者制作钛金属烤瓷修复体 5 9件 ;对照组 4 5例患者制作镍铬合金烤瓷修复体 6 7件。修复完成时和完成后 1月、18月随访 ,检查修复体颜色、颈缘变色、菌斑指数、牙龈指数、颈缘适合性 5项指标和瓷损坏。结果 :两组前 5项检查指标的比较无统计学差异 ,也均无瓷损坏。结论

Objective:The purpose of this study was to evaluate the clinical performance of the titanium metal porcelain restoration. Methods:The cases in this evaluation were divided into two groups. The experimental group consisted of 42 cases restored with the titanium metal porcelain restoration; the other 45 cases restored with Ni_Cr alloy porcelain restoration served as the control. The clinical performance of these restorations was observed at 1_month and 18_month follow_up. The evaluator examined the restoration for shade, marginal color, marginal fit, plaque index, gingival index, and porcelain defect.Results:For the shade, 92.8% of the cases in the experimental group were judged as satisfactory at 1_month and 18_month visit, whereas 91.1% in the control were evaluated similarly at the same visit. There was the marginal discoloration of 4 cases in the experimental group. But there was the marginal discoloration of 5～7 cases in the control. There were no significant difference in shade, marginal color, marginal fit, PLI and GI between the two groups .The cracking and chipping and separation of porcelain were not occurred. Conclusion:The titanium metal porcelain restoration should be used for the clinical application compared with the Ni_Cr alloy porcelain restoration.
