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...
متن کاملIn vitro microbiological analysis of bacterial seal at the implant-abutment interface using two morse taper implant models.
The objective of this study was to evaluate the bacterial seal at the implant-abutment interface using two morse taper implant models, by means of an in vitro microbiological analysis. For that were used 15 implants with mini-abutments tightened by friction, no screws (Group 1); and 30 implants with screw-tightened abutments, of which 15 received 20 N.cm of closing torque (Group 2) and the othe...
متن کاملAn in vitro investigation concerning the bacterial leakage at implants with internal hexagon and Morse taper implant-abutment connections.
PURPOSE To evaluate, in vitro, the leakage observed in internal hexagon and Morse taper implant-abutment connections. MATERIALS Ten specimens with internal hexagon and 10 with Cone Morse connection were used. The inner parts of 5 implants, per group, were inoculated with Pseudomonas aeruginosa (PS) suspension and 5 implants, per group, with Aggregatibacter actinomycetemcomitans (AA). The pene...
متن کاملMicroleakage at the abutment-implant interface of osseointegrated implants: a comparative study.
Microleakage can occur at the abutment-implant (A-I) interface in osseointegrated implants and may cause malodor and inflammation of peri-implant tissues. The degree of microleakage at the A-I interface of 5 implant systems was comparatively assessed at varying closing torques. Using colored tracing probes driven by a 2-atm pressure system, the interface microleakage of Brånemark, Sulzer Calcit...
متن کاملMicroleakage Evaluation at Implant-Abutment Interface Using Radiotracer Technique
OBJECTIVES Microbial leakage through the implant-abutment (I-A) interface results in bacterial colonization in two-piece implants. The aim of this study was to compare microleakage rates in three types of Replace abutments namely Snappy, GoldAdapt, and customized ceramic using radiotracing. MATERIALS AND METHODS Three groups, one for each abutment type, of five implants and one positive and o...
