Guidelines for occlusion strategy in implant-borne prostheses. A review

Abstract

Medium- or long-term failure of endosseous dental implants after osseointegration, when it has occurred, has been associated in the great majority of cases with occlusal overload. Overload depends ultimately on the number and location of occlusal contacts, which to a great extent are under the clinician's control. Much of our current understanding of occlusal contacts in this context is based on concepts derived from non-implant-borne prosthetics and has not been rigorously tested. The present article reviews occlussal contact designs and offers occlusion strategy guidelines for the main types of implant-borne prostheses.

Mandibular Full‐Arch Fixed Prostheses Supported on 4 Implants with Either Axial Or Tilted Distal Implants: A 3‐Year Prospective Study

“…Thus, apart from denture bending moments the impact of individual occlusal forces and the closing pressure should be discussed as causative factors for veneering problems and acrylic tooth fractures. Considering the type of opposite jaw dentition, retentions of the synthetic veneerings should be fabricated individually or possibly reinforced for avoiding potential fractures …”

In Vitro Evaluation of the Effects of Low‐Intensity Nd:YAG Laser Irradiation on the Inflammatory Reaction Elicited by Bacterial Lipopolysaccharide Adherent to Titanium Dental Implants

“…The ever‐increasing clinical experience in the use of endosseous dental implants has provided clues to detect, and possibly counteract, the main causes of medium‐ or long‐term failure of implant osseointegration, generally attributed to occlusal overload 4 and peri‐implantitis 5,6 . Overload can be easily controlled by the clinician because it ultimately depends on the number and location of occlusal contacts, whereas peri‐implantitis requires a specific therapeutic approach.…”

Occlusal Concepts Application in Resolving Implant Prosthetic Failure: Case Report

“…13,14 Some authors have recommended a clearance of 30 lm between implants and opposing teeth. 15,16 Consequently, the implant is not subject-ed to load during light or moderate dental contact. During high-intensity contacts, the implants and teeth will contact simultaneously.…”

“…During high-intensity contacts, the implants and teeth will contact simultaneously. 16 Positional changes of teeth may intensify the occlusal stress on implants. 13 Re-evaluation and periodic occlusal adjustments are needed to prevent the potential overloading of the implants from the positional changes.…”
