Single crowns on tooth root-resected molars: A retrospective multicentric study

Abstract

Statement of problem: Data regarding single restorations on molars treated with root resection and separation are limited.

Purpose: The purpose of this retrospective study was to evaluate the clinical success and survival of single crowns on root-resected molars.

Material and methods: Eighty-six molars were treated with root resection or hemisection, prepared with feather-edge margins and restored with single crowns in 73 patients. The patients were clinically evaluated during regular recall appointments in 2018. Data were analyzed with descriptive statistics.

Results: The mean follow-up time was 88.7 months (standard deviation, 70.6; range, 6 to 284). Six failures were recorded during the observation period, with a cumulative survival rate of 93%.

Conclusions: In this retrospective evaluation, single crowns on root-resected molars with feather-edge margins had clinical outcomes similar to those reported for single crowns on implants in the molar area. First molars and molars with 2 retained roots showed a better survival rate than second molars.
