Zaugg LK, et al. - The cement excess produced when cementing CAD/CAM-fabricated lithium disilicate (L) or zirconium dioxide (Z) crowns utilizing adhesive cement (A) or resin-modified glass ionomer cement (B) was examined in this study. The outcome of this study uncovered that utilizing crown venting was the most successful measure to decrease the amount of marginal excess cement, followed utilizing a pre-cementation device. They also noted that both techniques ought to be considered for clinical application to keep the marginal excess cement of one-piece zirconia implants to a minimum.
