Mechanical complications in implant-supported prostheses

Abstract

Mechanical complications in implant-supported prostheses represent a challenge in rehabilitative Dentistry, since they can compromise the stability of the treatment, reduce its longevity and generate the need for corrective interventions. The objective of this study was to analyze the main causes of these failures and identify strategies that can minimize their occurrence, ensuring greater predictability in implant-supported treatments. The research is justified by the need to understand the factors that influence these complications, enabling improvements in clinical and laboratory protocols. The methodology adopted was a bibliographic review based on the analysis of scientific articles and academic publications of relevance in the area. The results demonstrated that factors such as biomechanical overload, inadequate choice of materials and lack of periodic maintenance are among the main causes of mechanical failures. It was concluded that the adoption of preventive strategies, such as adequate planning of the distribution of occlusal forces, use of high-strength materials and regular clinical monitoring, can significantly reduce the incidence of these complications and increase the longevity of implant-supported prostheses.
