Intra‐oral adhesive systems for ceramic repairs: a comparison

Abstract

The aim of this investigation was to compare the bond strength of restorative composite resin to dental ceramic conditioned with primers and adhesives of various commercial repair kits. Three intra-oral ceramic repair systems--Silistor (Heraeus Kulzer), Cimara (Voco), Ceramic Repair (Vivadent)--were used on all-ceramic (IPS Empress 2, Ivoclar-Vivadent) substrate. Shear bond strength of restorative composite resin to substrate was tested after thermocycling and without thermocycling (n = 10). Substrate surfaces of the specimen after loading were examined microscopically (SEM). The highest bond strengths in both water-stored (7.0 +/- 5.7 MPa) and thermocycled conditions (2.5 +/- 1.8 MPa) were obtained with the Vivadent repair system, while the lowest values were observed with the Cimara system (0.6 +/- 1.4 MPa and 0.0 +/- 0.0 MPa, respectively). Shear bond strengths appeared to be significantly affected by thermocycling (ANOVA, P < 0.05). It is concluded that there are significant differences in the bond strengths of resin composites and ceramic substrate. The roughened surface does not necessarily provide a better bond strength; the bond strength of composite decreases with storage in water and after thermocycling. Bond strength values were generally low for all of the tested materials.

“…Replacing a failed restoration is not necessarily the most practical solution when the following factors are taken into account: replacement cost, more loss of tooth structure, and further trauma to the tooth 1,6) . For localized failures, intraoral repair could be an alternative treatment to restoration replacement which is clinically unacceptable and no longer satisfactory 1,4,7) . Intraoral repair is a minimally invasive approach that entails the addition of a restorative material -with or without prior preparation in the restoration 1,8,9) .…”

Efeito De Diferentes Tratamentos Superficiais Na Resistencia De Uniao De Reparo De Porcelana Com Resina Composta

“…Dentre os métodos capazes de produzir alterações superfi ciais na cerâmica, a literatura relata a utilização de asperização com pontas diamantadas (LACY et al, 1988;SULIMAN et al, 1993;EIKENBERG;SHURTLEFF, 1996;COCHRAN et al, 1998;KUMBULOGLU et al, 2003), jateamento com óxido de alumínio (BERTOLOTTI et al, 1989;WOLF et al, 1992;BERKSUN;SAGLAM, 1994;CHUNG;HWANG, 1997;ROBBINS, 1997), aplicação de agentes condicionadores, como o fl úor fosfato acidulado e o ácido fl uorídrico (SENDA et al, 1989;WOLF et al, 1993;TYLKA;STEWART, 1994;HOLLWEG, 1997; DELLA BONA; VAN NOORT, 1998, KUKIATTRAKOON;THAMMASITBOON, 2007). A literatura também relata a utilização de métodos tais como jateamento com partículas de óxido de alumínio-Al 2 O 3 (SHAHVERDI et al, 1998;WOLF et al, 1992;KIM et al, 2005;YESIL et al, 2007), asperização com pontas diamantadas (Kupiec et al, 1996), aplicação de silano (AGRA et al, 1993, DELLA BONA;NORTHEAST, 1994) e deposição de uma camada de sílica (SiOx) (OZCAN et al, 2006) sobre a cerâmica fraturada.…”

Evaluation of experimental phosphate and sulfur-based primer bonding to metal casting alloys

“…The solvent was eliminated in a rotatory evaporator and the product isolated by vacuum distillation. The product obtained was characterized and confirmed by 1 6.40 (s, 1H), 6.48 (s, 1H)), as described in a previous study [15]. The purity was determined by gas chromatography (Shimadzu GC-17A Gas Chromatograph, equipped with a FID detector).…”

“…Despite esthetic considerations and the increasing development and use of all-ceramic materials [1], metal-ceramic restorations are still considered as a feasible option in oral rehabilitation due to their mechanical resistance [2,3] and low cost when compared with metalfree restorations. Moreover, metal crowns are still the material of first choice when the remaining tooth structure is extensively weakened or when crown luting on a cast metal post is required.…”
