Purpose: Earlier studies on low-fusing ceramics have shown the occurrence of changes over time regarding surface and color. The present prospective study is an ongoing follow-up of an intraindividual comparison between two metal-ceramic systems, the Procera system (titanium copings veneered with a low-fusing ceramic) and noble-alloy copings veneered with a medium-fusing ceramic. Materials and Methods: Twenty-one crown pairs were fabricated for 18 patients. After 5 years, 18 crown pairs in 15 patients were available for comparison. The crowns were examined shortly after cementation (baseline), and after 1, 2, and 5 years. The crowns were rated according to the CDA system. Bleeding index and margin index were also evaluated. Results: Obvious changes regarding surface and color were noted for the titanium-ceramic crowns. The difference between the two types of crowns was statistically significant at 5 years (P = .004). The differences between the two systems regarding anatomic form, margin integrity, bleeding index, and margin index were small. Conclusion: Within the limitations of this study, it is concluded that low-fusing ceramic-veneered titanium copings are inferior to mediumfusing ceramic-veneered conventional copings regarding surface and color of the ceramic. Therefore, conventional ceramic-veneered crowns seem to be preferable, at least in the anterior area, where the esthetic requirements are greater than in premolar and molar regions. Whether possible changes in the properties of low-fusing ceramics will reduce the differences between the two types of metal-ceramic crowns remains to be proven. Int J Prosthodont 2003;16:70–73.
