THE EFFECTS OF DIE-SPACING ON POST-CEMENTATION CROWN ELEVATION AND RETENTION

This paper reviews the relevant dental literature concerning the effec t of die-spacing on crown elevation and pre- and post-cementation crow n retention. Techniques of providing die-spacing and measurement of th e thickness of die-spacer are discussed. A review of the role of the p rovision of a cement space in reducing post-cementation crown elevatio n is presented. Factors which may affect crown retention prior to and following cementation are also reviewed. The influence of variables in techniques and experimental design on the results of the studies revi ewed is discussed.
