High precision of the CONELOG implant-abutment connection

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 tigh- tened according to each manufacturer’s re- commendations. 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 displace- ment range (Fig. 3). Importance of the results: The precision of the implant-abutment con- nection is of major importance for the fabri- cation and later fit of the prosthetic restora- tions and their accuracy from the model to the patient’s mouth. Stability of the implant- abutment connection is strongly influenced by the precision of fit, the connection design (incl. positional index design) and the manu- facturing precision. The CONELOG implant-abutment connection showed evidences of high-precision manu- facturing and superior positional stability when compared with other conical connec- tions.

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.
