“…The implant surface is comparatively smooth, causing the cement failure at the interface of crown and cement, as there were remains of zinc phosphate cement at the inner surface of the copings. No pre-treatment was done on the abutment or coping in the present study making the surface as inert as suggested by (Rengasamy et al 2023). Also, for GIC, the solubility was higher than the other cement, and the susceptibility was seen with the desiccation and the water contact in the initial stages that can drastically compromise the mechanical properties of the luting cement as reported by the previous studies (Kalla et al 2022).…”

Implant-supported crowns are either cement-retained or screw-retained. Recently, function and esthetics have been given major focus as advances in implants have greatly improved the longevity of implant restoration. Superior esthetics is seen with cement-retained restoration and is more preferred. However, it is a controversial topic to select the ideal cement type for luting the implant-supported crown. The present study aimed to assess the retentive ability of different luting agents in titanium abutments on implant-supported crowns. The study assessed 60 samples divided into 3 groups of 20 subjects each where luting was done with three different types of cement, namely glass ionomer cement, zinc polycarboxylate, and zinc phosphate, respectively. A testing machine was used to assess the retentive strength of the three types of cement. The study results conclude that the highest retentive strength is seen with zinc polycarboxylate cement, followed by the glass ionomer and zinc phosphate cement.

Background: Few studies assessed the effect of coping material (particularly milled metal copings) on the retentive strength of cements and reported contradictory results. Thus, this study aims to assess the marginal leakage and retentive strength of implant-supported milled zirconia and cobalt-chromium (Co-Cr) copings cemented with different temporary cements. Materials and Methods: In this in vitro study, Zirconia and Co-Cr copings were fabricated on 100 straight titanium abutments. Each group of copings was divided into five subgroups (n = 10) for the use of different cements: permanent zinc-phosphate (ZP) cement, temporary zinc oxide eugenol cement (temp bond [TB]), calcium hydroxide-based temporary cement (Dycal [DC]), polymer-based eugenol-free acrylic-urethane temporary cement (Dentotemp [DT]), and methacrylate-based temporary cement (Implantlink [IL]). The retentive strength and marginal leakage of restorations were assessed. Data were analyzed by one-way ANOVA, Tukey, and Fisher’s exact tests (α = 0.05). Results: In the Co-Cr group, the retentive strength values (in Newtons) were as follows: ZP (411.40 ± 5.19) >DC (248.80 ± 5.01) >IL (200.10 ± 5.06) >DT (157.90 ± 5.19) >TB (98.50 ± 6.88). This order was as follows in the zirconia group: ZP (388.70 ± 5.35) >DC (226.60 ± 5.08) >IL (179.00 ± 3.71) >DT (136.00 ± 4.88) >TB (78.60 ± 3.50). All pairwise comparisons were statistically significant (P < 0.001). The difference in marginal leakage was not significant among the groups (P = 0.480). Conclusion: The type of coping material and cement type significantly affected retentive strength, but not marginal leakage, of implant restorations. Milled Co-Cr copings showed higher retentive strength than zirconia copings, and ZP cement followed by DC yielded the highest retention.
