Abstract
Purpose: To evaluate Ti-Base abutment height and cement type on the retentiveness of zirconiabased 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 <0.01). Although no significant difference was evidenced between resin cements for short abutments, Ultimate evidenced higher retention than U200 for tall abutments (P =0.043). Conclusions: Although Ti-Base abutment height has not influenced zirconia superstructures' retentiveness, resin-based cements significantly evidenced higher retention than glass ionomer and temporary cements.
