Article
Various loading protocols of implants have been established in practice. Clinical studies provide information on indication­related concepts that demonstrate a good prognosis of implant survival rates and implant success rates. Immediate loading, which is usually long­term provisionalization, is a procedure that guarantees a comparable prognosis to...
Article
The rejection of composite veneerings in fixed partial dentures is primarily caused by the inadequacy of the bonds between the metal framework and the composite veneering. The development of improved veneering composites necessitates an investigation of their clinical suitability compared with ceramic materials. Nineteen patients with at least two...
