The survival of dental implants with different implant-abutment connection systems

Open access


The aim of the study was to evaluate the survival of implants with different implant-abutment connection systems, in patients who had two kinds of implants implanted. In total, 240 implants were implanted - 91 implants with conical abutment Morse connection, and 149 with an internal hexagonal connection. During the follow-up period of 3 years and 10 months, the percentage of lost implants with a conical implant-abutment connection was 1.1%. Regarding the implants with hexagonal implant-abutment connection, this figure was 0.7%. Our work shows that there is a need for further research on the survival of dental implants. In this, the influence of other factors should be explored that are related both to the specific implant treatment, as well as to socio-demographic factors
