| Abstract | ||
| Statement of Problem: Resin bonded fixed dental prosthesis (RBFDP) are not indicated when the mesiodistal width of the missing tooth is needed to be adjusted. A New design of Veneer retained resin bonded dental prosthesis (VRFDP) is suggested to restore and redistribute the space. Materials and Methods: Two 3D models for 8 maxillary anterior teeth and first premolars; with missing tooth number 11, were drawn on AutoCad software to accommodate resin-bonded FDP (RBFDP) and veneer-supported fixed dental prosthesis (VRFDP). the file was exported and 10 epoxy resin models were 3D printed from each type using stereolithography technology. Ten FDP were milled from each STL file. Using high translucency zirconia blanks (Esthetic Explore) and sintered according to the manufacturer’s recommendations. Then, the FDP of each type were bonded to their corresponding dies according to the manufacturer’s directions. All specimens were subjected to cyclic loading test Specimens were cyclic loaded till failure. Data were collected, tabulated, and statistically analyzed. Results: Descriptive Statistics showed higher mean values of the VRB group (520.16±117.07) than the RBB group (449.19±163.97). One-Way ANOVA showed no significant difference between tested groups (P= 0.28). Conclusions: VRFDP scored higher cyclic loads mean values than RBFDP. VRFDP could present an acceptable treatment option for treating the missing central incisor situation. More investigations are needed to support or reject this claim. | ||
