BIO-MECHANICAL STUDY ON CONICAL IMPLANTABUTMENT CONNECTION STABILITY
Abstract:
Introduction. The implant systems with two or more components are much more used today.
The technical failure of the abutment – implant interfaces is more frequently encountered in the
posterior crowns. Aim. The objective was to evaluate the behaviour of the abutment-implant interface
under simulated masticator loadings as a function of the type of connection and of its structural
implementation. Material and method. The mechanical behaviour of different connection types between
implant-abutment was evaluated in vitro in conditions of simulated clinical loading. Results. Conical
connection system were not detected micros-spaces or micro-movements at forces up to 200 N. The level
of the forces as well as the design and precision of the integration as a functional structure are crucial
factors which influence the implant abutment reaction at loading. Conclusions. It can completely prevent
bone resorbtion systems using implants with a conical connection between the abutment and implant
without micro movements.
