Bacterial Leakage in Implants With Different Implant–Abutment Connections: An In Vitro Study

Abstract

The present study confirms previous results about the hermeticity of the cement-retained implant-abutment assembly, the very low permeability to bacteria of the conical implant-abutment connection, and the high prevalence of bacterial penetration of screw-retained implant-abutment assemblies.
