Survival of prosthesis over implants: literature review

Abstract

The survival of prostheses over implants is influenced by the adoption system and the types of implant-supported screwed and cemented prostheses, each with its own biomechanical characteristics, with an emphasis on elements such as adaptation, occlusion, esthetics, retention, reversibility and provisionalization. From this, the objective of the article is to analyze a surviving prosthesis over implants with morse taper system and biomechanical characteristics of screwed and cemented implant-supported prostheses. As a method, to characterize the research as a literature review, formed by a sample of 23 (twenty-three) national and international scientific articles published from 2010 to 2021 in databases such as SciELO, CAPES, LILACS, PubMed and Academic Google. The results show that there is no unanimity on which is the best type of prosthesis to increase the provision rates, as both types have advantages and disadvantages. With regard to the morse cone system, the results indicated that it is satisfactory for increasing the survival of the prostheses. In the end, it is concluded that the choice between screw-retained implant-supported prosthesis and the restoration over cemented implant-supported prosthesis will occur by the professional and will take into account the real needs and conditions of each case, since both techniques have advantages and disadvantages and/or that they cause or not high fee rates.
