Abstract
Objective: Evaluate clinically how differences between direct and semi-direct restorative techniques with the use of composite resin, in teeth with non-carious cervical lesions (LCNC) due to friction, in the requirements of: retention, marginal integrity, marginal discoloration and patient satisfaction. Case detail: It is a case report, in which a patient was selected where a patient with free demand was selected who had at least 4 LCNC, 2 in each hemi-arch, thus using the split mouth model. The LCNC were restored by 2 different protocols, direct and semi-direct technique using nanoparticulate composite resin, where 2 teeth were restored with one technique and another 2 with another, after performing the protocols, parameters previously described were evaluated, immediately and after 30 days in order to establish a protocol of better longevity and aesthetics. Final considerations: Restorations performed using the direct technique proved to be more effective for restorations in LCNCs, when purchased using the semi-direct technique, during the evaluated period.
