Some physical properties of implant abutment luting cements.
The dislodging force, the compressive strength at 24 hours, and the film thickness of four resin composite luting cements (UDA, UDA with fluoride, Panavia OP, and DenMat) and a conventional glass-ionomer cement (Shofu Type I) were compared. The axial force necessary to dislodge each cemented 0 degree abutment from an internally threaded Steri-Oss implant (n = 5) was then determined using a mechanical testing machine. UDA with fluoride appears to be a significantly stronger luting agent for abutment cementation than is either UDA or DenMat (P less than .05). DenMat resin composite cement exhibited the highest mean compressive strength whereas Panavia OP had the lowest value for film thickness.
