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.

Impaction occurs more frequently with maxillary canines than with any other tooth except maxillary third molars. For functional and aesthetic purposes, impaction must be treated in a manner that facilitates recreation of the anatomical structures in the canine region. The general treatment of choice is surgical and orthodontic restoration of the impacted canine. When this protocol is impossible due to anatomical limitations or the patient's indications, alternative treatments are necessary. The authors introduce two case presentations in which impacted maxillary canine teeth were restored with alternatives to orthodontic therapy.
