“…The present study agrees with the last study because crowns cemented with HC presented greater retention than TB. Several studies showed that non-eugenol zinc oxide-based cements are the least retentive among temporary cements (22,23) especially when abutments were not prepared or rough (8), as in the present study.…”

This study aimed to verify marginal fit and the effect of cement film thickness standardization on retention of provisional crowns made with prefabricated acrylic cylinders on abutments, using two temporary luting agents subjected or not to mechanical cycling. Provisional crowns were made from bis-acryl (Luxatemp Fluorescence) or methyl methacrylate (Duralay) resins on acrylic cylinders and marginal fit and cement film thickness were evaluated. For retention evaluation, crowns were cemented with two temporary luting agents: non-eugenol zinc oxide (Tempbond NE) or calcium hydroxidebased (Hydcal) cements and subjected to tensile strength in a universal testing machine. After cleaning, debonded crowns were cemented again, subjected to mechanical cycling and retention was reassessed. The results of marginal fit and cement film thickness were analyzed by Student's t-test while retention of cements before and after mechanical cycling was analyzed using a mixed linear model. Methyl methacrylate crowns presented greater marginal misfit (p=0.001) and occlusal cement film thickness (p=0.003) than the bis-acryl ones. No difference was observed at axial cement film thickness (p=0.606). Resins (p=0.281) did not affect crown retention, but luting agents (p=0.029) and mechanical cycling (p=0.027) showed significant effects. The only significant interaction was mechanical cycling*luting agents, which means that luting agents were differently affected by mechanical cycling (p=0.002). In conclusion, the results showed that bisacryl resin associated to calcium-hydroxide luting agent provided the best retention and lower cement thickness.

“…This may come as some surprise to clinicians in considering the widespread use of glass ionomer cements for the cementation of natural tooth crowns. This finding is consistent with a previous studies that demonstrated that glass ionomer cement showed significantly lower retention than zinc phosphate and resinous cements, and similar retention to zinc oxide cement without eugenol (13,15) .In the present study, no pretreatment was performed on the abutments, and glass ionomer cement does not adhere to an inert surface. Furthermore, the solubility of glass ionomer cement is more than that of other cements, and it is very susceptible to early water contact and desiccation (16) ,which can dramatically reduce the mechanical properties of the cement (17) .…”

Aim:The purpose of this study was to evaluate the retention values and marginal adaptation of implant-supported metal copings using different luting agents. Material and Method:Forty implant fixtures and solid abutments of 7mm height were embedded vertically in epoxy resin blocks. Metal copings with a loop on the occlusal surface were fabricated using base metal alloy. The copings were luted using four different cements (Multilink N, Fuji Plus, Fuji1 and Adhesor) under static load of 5kg (n=10). All specimens were subjected to 1000 thermal cycles between 5˚c and 55˚c with a dwell time of 10 seconds in a thermocycling device. Marginal accuracy was detected before and after cementation of all specimens by stereomicroscope. TheTensile force required to dislodge the copings were determined by a computer controlled universal testing machine with a cross-head speed of 0.5 mm/ min.The force in Newton(N) required to remove the copings was recorded. Data was collected and statistically analyzed.Results: Multilink N and Fuji1 had the highest and the least mean retentive strength respectively. There was no significant difference between MultilinkN, Fuji Plus and Adhesor. The absolute marginal discrepancies of cements were in reducing order zinc phosphate , resin modified glass ionomer, glass ionomer and resin cement.Conclusion: within the conditions of this study, resin cement, the resin modified glass ionomer and zinc phosphate had statistically the same retentive quality and are recommended for definitive cementation of single implant-supported restoration. Different luting media had a definite effect over the final fit of all metal copings, but they were all within the clinically accepted level of 100 µm.

ÖZET Amaç: Bu in vitro çalışmada; farklı "computer aided design/computer aided manifacturing (CAD/CAM)" materyallerinden hazırlanan implant destekli tam seramik kronların tutuculuk özelliklerinin incelenmesidir. Gereç ve Yöntemler: Her bir grupta 8 adet olacak şekilde 4 farklı CAD/CAM materyalinden (IPS e-max CAD-IPS, Vita Suprinity-VS, Vita Enamic-VE ve Vita YZ ST-ST) toplam 32 adet kron hazırlandı. Kronlar, zirkonya "abutment"ler üzerine rezin siman ile simante edildi. Kronların tutuculuk özellikleri, universal test cihazında her bir krona dikey yönde 1,0 mm/dk çekme hızıyla ayırma kuvveti uygulanarak test edildi ve desimantasyona sebep olan maksimum kuvvet belirlendi. Elde edilen veriler tek yönlü varyans analizi (ANOVA) ve post-hoc Tukey HSD testleri kullanılarak istatistiksel olarak karşılaştırıldı. İstatistiksel anlamlılık düzeyi p<0,05 olarak değerlendirildi. Bulgular: Gruplar arasındaki retansiyon kuvveti değerleri karşılaştırıldığında anlamlı farklar saptanmıştır (p<0,05). En yüksek retansiyon kuvveti VS grubunda elde edilmiş ve onu sırasıyla IPS, VE ve ST grupları izlemiştir. Sonuç: İmplant destekli tam seramik kronların tutuculuk özellikleri, protetik restorasyon için kullanılan materyal tipinden etkilenmektedir.Anah tar Ke li me ler: İmplant destekli kuron; tam seramik; retansiyon ABS TRACT Objective: The purpose of this in vitro study was to investigate the retention properties of implant supported full ceramic crowns prepared from different CAD/CAM restorative materials. Material and Methods: A total of 32 crowns, 8 in each group, were prepared from 4 different CAD/CAM materials (IPS e-max CAD-IPS, Vita Suprinity-VS, Vita Enamic-VE and Vita YZ ST-ST). Crowns were cemented on zirconia abutments with resin cement. The retention properties of the crowns were tested in a universal testing machine by applying a separation force at a cross-head speed of 1.0 mm/min in vertical direction and the maximum force leading to decementation was determined. The obtained data were statistically compared using oneway analysis of variance (ANOVA) and post-hoc Tukey HSD tests. Statistical significance was determined at p<0.05. Results: Significant differences were found among the groups with respect to the retention strengh values (p<0.05). The highest retention strength was obtained in the VS group followed by the groups IPS, VE, and ST, respectively. Conclusion: The retentive properties of implant supported full ceramic crowns were affected by the type of material used for prosthetic restoration.

Comparison of 3 Luting Agents on Retention of Implant-Supported Crowns on 2 Different Abutments

Abstract: The increase in surface area of abutment did not result in improved retention. The present results suggest using ZP rather than GI and eugenol-free ZO in implant-supported crowns to provide higher retention.
