COMPARATIVE ANALYSIS OF THE MECHANICAL CHARACTERISTICS OF DIFFERENT CONNECTIONS IN OSSEOINTEGRATED IMPLANTS

Abstract

This article sought to perform a comparative analysis of the mechanical characteristics of different connections in osseointegrated implants, in order to support clinical decision-making based on scientific evidence. Using the integrative literature review methodology, studies published in the last ten years that addressed comparisons between external hexagon, internal hexagon and Morse cone connection systems were selected, with emphasis on aspects such as resistance to loosening, load distribution, mechanical stability and biological complications. The results indicate that the Morse cone connection stands out for its high resistance to loosening, uniform stress distribution and lower incidence of mechanical and biological failures, compared to hexagonal connections. The external hexagon connection presented inferior performance, being more susceptible to microgaps and peri-implant complications. It is concluded that the type of connection directly influences the longevity and predictability of implant-supported rehabilitations, with the Morse cone being a promising alternative for greater stability and clinical success.
