CONICAL CONNECTION: POSITIONAL STABILITY
The theoretical considerations and the established experimental set-up
developed by Semper et al. were recently used to investigate the position
stability of different implant systems with a conical implant-abutment

found to be possible in all tested implant systems, the values for rotational
displacement of the CONELOG

Implant System were significantly lower
than the ones of the other three implant systems. The median rotation was
0.25°, and the maximum range was 2.14° in the CONELOG

implants. Since
the analytical and experimental results for CONELOG

were in very good
agreement, the authors supposed high-precision manufacturing for this im-
plant system.
