Several research groups analyzed and compared the stability of different implant-abutment connec- tions. The CAMLOG ® Tube-in-Tube TM connection with its cam- groove index design showed favorable results in these analyses with regard to precision in reproducing the abutment position, rotational fit as well as load distribution and load-bearing capacity. Although conical connections may have design-related disadvantages regarding precision of fit and load distribution, the CONELOG ® implant-abutment connection demonstrated in studies evidence of high-precision manufacturing and superior positional stability when compared to other conical connec- tions.
