Comparative study of bacterial microfiltration in the implant‐abutment interface, with straight and conical internal connections, in vitro

Abstract Objective to determine the presence of marginal bacterial microfiltration in the IAI in different implant/abutment systems, in vitro. Material and methods Fifty‐six implants from seven different brand names, 4 with cone and 3 with straight connections were used, implant and abutment were co...
