A technique to provide cement spacing for cast post‐cores prior to construction of their crowns is described. The axial lift of crowns cemented with zinc phosphate was greater, but not significantly, for crowns constructed on non‐spaced post‐cores compared with crowns constructed on spaced post‐cores. Three materials were evaluated to determine their effectiveness in providing cement spacing for post‐cores. The phenomenon of post‐core ‘wedging’ during luting was identified.
