Brief Summary

Congenitally missing tooth is one of the most common anomalies in human dentition. The treatment options of lateral incisor agenesis are closing the space with orthodontic treatment, implant treatment, conventional fixed dental prosthesis (FDPs) and resin-bonded fixed dentures (RBFDs). RBFDs are used frequently for single tooth absence in the anterior region due to their minimal invasive properties, high clinical success and patient satisfaction. With the development of new and stronger materials, RBFDs with metal framework have been replaced by glass ceramic, lithium disilicate, fiber-reinforced composite (FRC) and zirconia. The aim of this study is to evaluate the clinical performance of CAD/CAM single-retainer monolithic zirconia ceramic RBFDs which cemented with two different resin cements.

Outcome Measures

Primary Outcomes (1)

  • Survival rate of zirconia ceramic RBFDs

    The survival was evaluated as described in the studies of Chai et al. (1). They described the survival as "the period of time starting at the cementation of the restoration and ending when the restoration was shown to have irreparably failed". The fracture was evaluated according to the study of Heintze and Rousson (2). They made a classification for fracture of zirconia restorations. Three grades of fracture treatment were assigned to this classification: (1) Grade 1: Fracture surfaces were polished. (2) Grade 2: Fracture surfaces were repaired with resin-based composite. (3) Grade 3: Severe chipping fractures required replacement of affected prostheses. 1.
