Abstract

Introduction-The retention of cemented prosthesis has been shown to be influenced by various parameters such as abutment size (height and width), abutment texture, the convergence angle between the walls of the abutment and the cements. Factors that may affect the retention of cast restorations include geometry of abutment preparation, abutment taper, surface area, abutment height, surface roughness, retentive grooves, and the luting agent used.
Material and method-20 straight shoulder type titanium abutments with abutment screws as well as prefabricated plastic copings and corresponding 12 mm-long stainless steel laboratory implant analogs were used. The abutments were divided into two subgroups of 10 abutments each. The implant abutment screws with the abutments were tightened to the analogs with a screwdriver to a torque of 20 Ncm. The access screw hole was blocked with composite resin. The analog with its abutment was placed in the hole while the cast coping was cemented.
Result- The mean retentive forces of standard machined abutments cemented with non-eugenol cement showed 49.93N and with zinc phosphate cement showed 212.80N.
Conclusion- The retention of cast copings cemented on plain abutments with zinc phosphate cement was more than 4 times greater than those cemented with zinc oxide provisional cement.
