Abstract

Missing single teeth may be replaced using an endosseous dental implant. The CeraOne system uses a gold alloy cylinder that is cemented to a titanium abutment. This study evaluated the effect of three variables on cement failure loads required to unseat a gold alloy cylinder from its abutment. Two chimney heights (commercially available 3.7 mm and custom fabricated 5.0 mm), three luting agents (zinc phosphate, Tempbond NE, and Tempbond), and two luting volumes (0.01 mL and 0.02 mL) were tested. A mechanical testing instrument was used to exert a uniaxial tensile force on the gold cylinders 2 hours after cementation. An analysis of variance and Tu key post hoc test demonstrated that both the choice of luting agent and chimney height affected cement failure loads (P0.0001). An interactive effect between luting agent and chimney height was observed, with the combination of zinc phosphate and a 5.0 mm abutment-gold alloy cylinder complex resulting in significantly greater retention (P0.0001). The use of 0.01 mL or 0.02 mL of luting agent resulted in comparable retention values. The results indicate that both chimney height and choice of luting agent may affect retention of a CeraOne gold alloy cylinder. The use of 0.01 mL of luting agent is recommended to minimize expression of excess cement at the restoration-abutment interface.
