Abstract
Purpose: clinical and laboratory evaluation of all ceramic and metal-ceramic cantilever resin bonded fixed partial dentures. Materials and methods: Laboratory study: Fracture strength test was evaluated before and after TCML process for a total of 32 cantilever RBFPDs constructed either from glass-infiltrated zirconia ceramic or base metal alloys according to manufacture recommendation. Clinical study: A total of 16 anterior cantilever RBFPDs were made either from the glass-infiltrated zirconia ceramic or base metal alloys. After cementation, patients were recalled every 6 month to evaluate the restorations with regard to function and possible failures. Results: Fracture strength results All specimens, subjected to TCML, survived with no failures. Similarly, significant differences were found for the fracture strength values between different groups. Clinical study results There were no significant differenced as regard to marginal adaptation, retention, periodontal health, fracture at different time of evaluation period in each group or between groups. Conclusions: Within the limits of this study the following conclusions could be drawn: 1. All tested restorations have the potential to withstand occlusal forces applied in anterior regions; TCML has an effect on the survival of this type of restorations. 2. Although the clinical follow up period was relatively short both metal-ceramic and all-ceramic cantilever resin bonded fixed dental prostheses present a promising alternative for clinical application.
