Evaluation Of The Clinical Effectiveness Of The Conometric Concept - A Systematic Review

Background: ACone-in-cone Morse taper connection between abutments and crowns has been proposed to retain implantsupported definitive fixed dental prostheses(FDPs). This prosthetic approach, named the“Conometric Concept,” was used to retain both lithium disilicate (LS2) and zirconia restorations.The conometric concept consists of a cone-in-cone connection between an abutment and the respective coping to retain an implant supported restoration without either screws or cement. The fit between abutment and the restoration is achieved with prefabricated components. The conical coupling abutments use the friction between the abutment and the titanium coping to retain a prosthesis without the use of cement. The restoration has no access holes and can be removed easily with a spring fixed partial denture remover. The emergence profile of the restoration can be placed sub-gingivally without the risk of cement remaining at the abutment coping interface. The main objective of this study is to critically review articles that have used conometric concept and to evaluate its clinical effectiveness
