Evaluation of posterior indirect resin composite restorations with proximal box elevation technique.
Restoration of large posterior defects extending below the cemento-enamel junction (CEJ) with coverage of one or more cusps represent a very common clinical situation. When restoring deep cervical margins biological and technical operative problems may occur. In order to make clinical procedures less fault-prone 'Proximal Box Elevation' (PBE) is an option that refers to application of composite resin in the deepest parts of the proximal areas in order to reposition the cervical margin supragingivally prior to cavity preparation for an indirect restoration.
This project aims to evaluate the clinical performance and periodontal status of posterior indirect composite restorations with PBE. According to study design at least 60 patients will be recruited to project and 80 restorations will be evaluated. The project will be carried out at the School of Dentistry, Istanbul Medipol University,Turkey.
