Abstract
Statement of problemData regarding single restorations on molars treated with root resection and separation are limited. PurposeThe purpose of this retrospective study was to evaluate the clinical success and survival of single crowns on root-resected molars. Material and methodsEighty-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. ResultsThe 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%. ConclusionsIn 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.
