Semper Hogg et al. (2015) compared the CONELOG implant-abutment connection to other systems with conical connections, i.e. Nobel Active, Ankylos C/X, Astra Tech, Straumann Bone Level, and Straumann Tissue Level. The abutments were torque tightened according to each manufacturer’s recommendations. CONELOG showed the best results in terms of rotational displacement (Fig. 1) and canting moment range (Fig. 2) and very good results in terms of vertical displacement range (Fig. 3). Importance of the results: The precision of the implant-abutment connection is of major importance for the fabrication and later fit of the prosthetic restorations and their accuracy from the model to the patient’s mouth. Stability of the implantabutment connection is strongly influenced by the precision of fit, the connection design (incl. positional index design) and the manufacturing precision. The CONELOG implant-abutment connection showed evidences of high-precision manufacturing and superior positional stability when compared with other conical connections.

Superior precision of the implant- abutment connection for CAMLOG® and CONELOG® Implant Systems 2. Advantages of a good precision: a. Positional stability of supraconstruction b. Better passive fit c. Less abutment screw failure d. Time saving (e.g. less adjustment) 3.Beneficial for the patient, the dentist, and the dental technician Fig. 2: Canting moments of 6 implant systems.
