Microbial leakage through the implant-abutment interface of Morse taper implants in vitro.

Objectives: The aim of this study was to determine and compare the frequency of bacterial leakage of Streptococcus sanguinis biotype II along the implant-abutment interface between two systems of morse taper dental implants. Different methods of activation of the taper abutments were used: tapped-in (Bicon) and screwed-in (Ankylos).

Materials And Methods: Twenty sterile assemblies were used and attached, 10 Bicon and 10 Ankylos implants, according to manufacturers' specifications.
