Occlusion in implant prosthodontics

The Relationship between Dental Occlusion and “Prosthetic Occlusion” of Prosthetic Restorations Supported by Natural Teeth and Osseointegrated Dental Implants

“…Biomechanical loading refers to the way in which occlusal/masticatory forces are transferred to dental implants by different types of prosthetic restoration, which occurs during static and dynamic occlusal contacts, i.e. mandibular movements [5,6,81,82]. Scientific studies [83][84][85] have shown that mandibular movements and function (by form and velocity), chewing efficiency (habitual chewing) are very similar in natural dentition and implant prosthetic restorations compared to wearers of removable conventional complete dentures thanks to the phenomenon of osseoperception.…”

“…In addition to direction, occlusal forces may show differences in duration and intensity during normal or parafunctional activity of the masticatory system. Conditions of increased muscle activity due to bruxism, unbalanced static and dynamic occlusal contacts on different types of implant prosthetic restorations, lack of passive fit between prosthetic components (mesostructure), prosthetic restorations and dental implants are potential factors for prolonged and more intense occlusal overload, which consequently increases the occurrence of biological and technical complications in implant prosthetic restorations [82,[89][90][91][92][93].…”

Occlusal considerations and principles in Dental Implant

“…The implant prosthesis should just barely contact and the surrounding teeth in the arch should exhibit greater initial contacts. 1 Hence, in cases of implants restorations opposed by natural teeth, the dentist should use a heavy bite force followed by a light bite force to differentiate between the occlusal contacts. Heavy bite forces causes depression of the natural teeth and positions them closer to the implant and thus permits equal sharing of the load.…”
