Abstract:

Objective:The purpose of this study was to evaluate the clinical performance of the titanium metal porcelain restoration. Methods:The cases in this evaluationwere divided into two groups. The experimental group consisted of 42 cases restoredwith 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 restorationswas observed at1-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:Forthe 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 andGI between the two groups .The cracking and chipping and separation of porcelainwere notoccurred.Conclusion:The ti- tanium metal porcelain restoration should be used for the clinical application compared with the Ni-Cr alloy porcelain restoration.
