This study evaluated the cervical fit of cemented metal–ceramic and In-Ceram implant-supported crowns, before and after the cementing procedure.

Materials and methods

Twenty crowns cemented on implant abutments are divided into two groups (n = 10): Group 1 – cemented metal–ceramic crowns and group 2 – cemented In-Ceram crowns. The marginal adaptations before and after cementation were evaluated in a comparison microscope with an error of 1 μm. All crowns were cemented with zinc phosphate cement.


The cervical misalignment of cemented crowns before cementation (52.65 ± 11.83 and 85.73 ± 14.06 μm) was lower than that after cementation (66.80 ± 15.86 and 89.36 ± 22.66 μm).


The cementing procedure interferes with the marginal fit of cemented crowns on implant abutments, with the prosthesis having better adaptation before cementation. Cemented metal–ceramic crowns exhibited better cervical adaptation than In-Ceram crowns cemented before and after the cementing procedure.

Clinical significance

The maintenance of gum health and the longevity of prosthetic restorations are closely related to the restoration's marginal integrity.
