Abstract:

A good occlusion can be defined as synonymous with a physiological occlusion; i.e., it is comfortable for the patient, it is functioning without problems, and it is stable and does not change.An interesting question is: Does the occlusion of restorations on natural teeth and on oral implants is quite the same?At the early stage of implant prosthodontics, the different attachment between teeth and implants to the bone was emphasized as very important. With the increasingexperience of successful implant treatment using varying occlusal principles, this difference seems to be of minor or negligible importance. At present, it seems prudent to accept that principles and methods applied in conventional prosthodontics can in general be used also for implant prostheses.Occlusion may seem complicated but is seldom mysteriousor difficult. Complex theories of occlusion and sophisticatedinstruments for jaw registration should be abandonedbecause they have never been documented to be necessaryfor successful results.Occlusion can be managed successfullyby using simple methods for jaw registration and differentocclusal concepts. The study of occlusion involves not only the static relationship of teeth but also their functional interrelationship and all the components of the masticatory system. The muscles of mastication, the neural feedback pathways, the temporomandibular joints and the shape of the occluding surfaces of the teeth influence the positions and movements of the mandible. The way in which teeth meet and move over each other must be understood so that any restoration placed in a mouth will be part of a harmoniously functioning occlusion. Every restoration, whether a simple amalgam filling or complex crown andbridgework and implant-supported restorations, which involves the occlusal surface will affect the occlusion. Therefore, restorations should be planned so that they do not cause effects that exceed the adaptive tolerance. The aims of the lecture are; clarification the types of dynamic occlusion, the differences between implant and natural teeth related to functional occlusion and finally the evidence-based approach for implant occlusion.
