Partial laminate veneers is a type of dental restoration made of a glass-matrix ceramic used to restore small teeth fractures, or to correct morphology defects of teeth (i.e.: diastema, conoid teeth or small misalignment). As tooth surface reduction, or tooth preparation is not needed for this type of restoration, it can be considered as a non-tooth preparation minimally invasive procedure.
As non-preparation is required for the restoration with ceramic partial laminate veneers, bonding relies on adhesion between the intaglio surface of the ceramic restoration and the tooth surface, which in most of the cases is enamel. For this purpose, many light-curing resin cement materials are available for bonding procedures. Nowadays, pre-heated resin composites are available as a resin luting material which has been indicated for laminate veneers and partial indirect posterior restorations.
As pre-heated resin composite has not been yet studied for partial laminate veneers, the objective of this randomized split mouth clinical trial, is to evaluate the survival of ceramic partial laminate veneers when bonded with two different resin composite luting agents.
