The article analyzes the ceramic and composite veneering methods for implant-supported fixed prostheses. The factors to consider when choosing between ceramic and resins systems are esthetics, abrasion resistance, polishability, repair options, and cost. Composite veneers have an increased incidence of fractures, citing cohesive fractures caused by insufficient transversal or shear resistance of the material. There are limitations in modifying completed metal-ceramic restorations and localized chipping on metal-ceramic restorations are said to be time-consuming and expensive. The authors recommend the use of composite-veneered superstructures only for long-term temporary restorations or on an experimental basis. |
