Brief Summary
The purpose of this study is to evaluate the clinical outcome of resin-bonded fixed dental prostheses (RBFDPs) pretreated with nanostructured alumina coating (NAC). The study adopts a prospective, randomized, controlled, double-blind design contrasting the use of NAC to air-borne particle abrasion (APA) (control) as a surface pretreatment method of zirconia RBFDPs used for replacing missing central or lateral incisors. The primary outcome evaluated is the retention/survival of the zirconia RBFDPs pretreated with APA and NAC.
Eligibility Criteria
Inclusion Criteria: 1\. Patients with missing central or lateral incisor Exclusion Criteria: 1. inadequate edentulous space for the pontic 2. signs of bruxism 3. abutment tooth with active periodontal or periapical disease 4. inadequate enamel bonding surface of the abutment tooth 5. inadequate interocclusal space for a retainer wing and a proximal connector 6. pontic guidance 7. physical or psychological disease likely to interfere with normal conduct of the study
