Effect of CAD/CAM Abutment Height and Cement Type on the Retention of Zirconia Crowns

Purpose:
To evaluate Ti-Base abutment height and cement type on the retentiveness of zirconia-based restorations.
Material and methods:
Four millimeter (tall) and 2.5-mm-height (short) abutments along with temporary (provisional), glass ionomer (Meron), self-adhesive (U200), and conventional resin cement (Ultimate) were evaluated using pull-out testing (n = 10 crowns/group).
Results:
Tall and short abutments demonstrated similar retention for all within cement comparisons, except U200 (P = 0.032). Resin cements exhibited superior retentiveness than others (P
