Customized titanium single-implant abutments: 2-year follow-up pilot study
Abstract
Purpose: The aim of this study was to describe an alternative technique to fabricate single-implant restorations by using adjustable titanium abutments with porcelain applied directly to the abutment, and to follow an early group of patients treated with these crowns.
Materials and methods: Seventeen randomly selected single crowns were consecutively placed in 14 patients and then followed for 2 years. A protocol of using healing abutments, implant impressions, and adjustment of the final abutment in the laboratory was used to fabricate the crowns.
Results: The clinical result revealed few clinical problems, and the mean marginal bone loss was 0.4 mm (standard deviation +/- 0.57 mm) after 1 year in function.
Conclusion: The conclusion drawn, based in part on published literature, was that occurrence of mucosal inflammation and marginal bone loss was not related to the use of the present protocol.
