The Effect of Various Cementing Agents on Occlusal Discrepancy Using an Intra-Oral Scanner: An In Vivo Study

A marginal fit of all-ceramic crowns is a prerequisite for the long-term clinical success dental restoration. Few in vivo studies have investigated effect film thickness various luting agents on vertical discrepancy. This study evaluated influence three cements occlusal discrepancy milled using complete digital workflow. Forty-three patients treated students’ clinic Tel-Aviv University with 45 single posterior digitally prepared monolithic were included study. The randomly divided into groups different resin agents: self-adhesive cement, resin-modified glass ionomer cement and adhesive cement. intra-orally scanned before after cementation. two standard tessellation language (STL) files each crown superimposed software, between four six measurements made at surface to demonstrate discrepancies. One-way ANOVA (α = 0.05) was used. ranged from 2 38 μm. mean values (µm): 12.93 ± 4.74, 19.05 4.60 13.69 5.17. There significant differences (p 0.004), 0.013). Distal ridge significantly group < 0.001) 0.021). no measurement points 0.377), nor 0.388), or 0.905). cementation procedure results discrepancies within acceptability. Resin-modified produced more than did.
