Summary

This study quantitatively compared cement residues of two resin cement types around implant-supported restorations (ISR) with a crown-abutment margin located at the gingival level. This prospective, single-blinded, cross-over clinical trial compared optically detectable cement remnants between Self-Adhesive Resin Cement (RC) and Resin-Modified Glass Ionomer Cement (RMGIC).

Detailed description

This prospective, two-arm, non-randomized, clinical trial compared detectable cement remnants on 30 patients and 60 ISR. Two cements were compared; self-adhesive resin (RC) and resin-modified glass ionomer (RMGIC). Comparisons were carried out on identical pairs of ISR tested within the same patients with a 1-week healing interval. The primary outcome variable was the ratio of cement-covered area to total crown area. Areas were analyzed ex-situ by standardized digital image analysis.

Conditions

• Dental Cements

Interventions

Type	Name	Description
OTHER	self-adhesive resin cement (RC)	Single-unit implant-supported single crowns were cemented to the abutments using a self-adhesive resin cement (RC). Residual cement was removed, and the restorations were retrieved for analysis of cement remnants.
OTHER	resin-modified glass-ionomer cement (RMGIC)	Single-unit implant-supported single crowns were cemented to the abutments using a resin-modified glass-ionomer cement (RMGIC). Residual cement was removed, and the restorations were retrieved for analysis of cement remnants.
