[Modification of some occlusion concepts in implant dentistry: thoughts inspired by clinical experience]

Implantology is nowadays a common tool in dentistry. While studying a case and selecting the future restoration, implants have to be considered when possible. Due to the functional differences between an implant and a natural tooth, the classical occlusion principles need to be considered. The prostheses have to be built according to the magnitude and direction of the forces that will be applied on the abutments. The prosthetic work and the occlusal equilibration are different in a patient with implants than in a patient with natural dentition. The occlusal concept will not be the same in the case of single implants surrounded by natural teeth, in the case of a mixed implant-tooth-supported fixed reconstruction and in the case of a full fixed bridge on implants. The purpose of this paper is to discuss the clinical consequences of these differences.
