&ndsp;&ndsp;Retention is considered to be one of the key factor that influences long term success of fixed partial denture prosthesis. It is by the virtue of which restoration is prevented from getting dislodged by forces parallel to the path of withdrawal. Taper is one factor that predominantly influences retention of the prosthesis. Also, the parallelism of the axial walls of abutment teeth is fundamental for the accurate placement of a fixed partial denture. It is necessary that abutment teeth for fixed partial denture be reduced adequately to remove any undercut, maintaining a minimum axial taper to ensure optimum retention. Thus this article describes methods to measure taper and assess the relative parallelism of the prepared abutment teeth to ensure long term success of cement retained fixed restorations.
