Overview
Brief 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.

- •poor oral hygiene as determined by the Oral Health Index (OHI)
- •pregnant or lactating
- •presence of uncontrolled medical systemic conditions, e.g. diabetes;
- •ongoing or past medical treatments affecting wound healing, terminated less than 3 months prior to the study-related intervention
Outcomes
Primary Outcomes
Relative ratio between the detectable area covered by cement remnants per crown site and the total crown
Time Frame: Crowns were retrieved for analysis immediately after intraoral cementation and residual cement removal.
Digital photographs of the specimens were obtained using custom-made equipment with a standardized distance. The images were analyzed as follows: the contours of the area covered by residual cement were identified visually after optical magnification and marked; the contours comprising the entire surface area of the prosthetic superstructure, i.e. abutment and crown, were determined; the ratio between the area covered with cement and the total surface area per aspect of the specimen was calculated.
