“…Regardless of the microstructure of the restorative material, adhesive luting protocol requires conditioning of the intaglio surface of the restoration to enhance the bond strength of restorative material to resin cement. It has been reported that surface treatment affects not only bond strength but also mechanical and optical properties of ceramics . Therefore, this in vitro study investigated the effect of different surface treatment methods on the flexural strength, color, and translucency of current CAD/CAM restorative materials.…”

Flexural strength results of the untreated specimens (control groups) of the present study were in agreement with previous studies, 28,29 which reported that lithium disilicate ceramic showed higher flexural strength than the resin-based materials.…”

“…It has been demonstrated that airborne-particle abrasion and laser application cause a color change and decrease translucency of lithium disilicate ceramic. 22,23 Although surface treatment is an important step to enhance micromechanical retention between the restorative material and resin cement, the effect of any surface treatment on the mechanical and optical properties of restorative material should be considered. To the best of the authors' knowledge, no study has evaluated the effect of surface treatment methods on the flexural strength, translucency, and color of novel CAD/CAM materials.…”

“…Great development of all ceramic systems for dental restoration occurred in the last 20 years, which provided the clinician a better aesthetic alternative for anterior and posterior restorations (1). This preference is directly related to the success of ceramic-resin bond, which contributes to the restoration's longevity (2).…”

The objective of this study was to evaluate the effect of passive or active phosphoric acid (PA) application after hydrofluoric acid (HA) treatment on the microshear bond strength of lithium disilicate. Thirty ceramic discs were made with IPS Emax 2 (10 mm thick and 10 mm diameter). The specimens were divided into 3 groups, A: 9.6% HA application; AF: 9.6% HA application + cleaning with 37% PA in passive mode and AFF: 9.6% HA application + cleaning with 37% PA in active mode. For the microshear test, four tygons (0.9 mm diameter and 0.2 mm high) were filled with resin cement (RelyX Ultimate) and placed on the ceramic disks. After testing, the fracture modes were examined under scanning electron microscopy. Data were analyzed by one-way ANOVA and Tukey's post test (α=0.05). The bond strength values were significantly higher in Group AFF (11.0±2.5 MPa) compared with group A (8.1±2.6 MPa) (p<0.002). AF group was not statistically different (9.4±2.5 MPa) from Group A. It was concluded that the active application of 37% PA after 9.6% HA increases the microshear bond strength values between the resin cement and lithium disilicate ceramic.

Matching a porcelain restoration is a difficult task for both the dentist and the dental technician. In order to improve communication, it was suggested that a new previsualization technique with a new modeling liquid could be introduced. This study investigates the effect of this modeling liquid on color, translucency, and biaxial flexure strength on different types of veneering porcelain. A total of 42 samples were tested for IPS e.max veneered discs, feldspathic discs and the porcelain fused to metal discs. Twenty‐one were prepared with the manufacture liquid, while the other 21 were prepared with Visual‐Eyes modeling liquid. The porcelain powder was prepared for the Visual‐Eyes liquid by removing the food dyes with a specific firing cycle recommended by the manufacture. The porcelain mixes were layered using standardized Teflon molds of different thicknesses. The color and translucency and the biaxial flexure strength were tested. The results revealed statistical significance in the translucency between the liquids in all types of veneering porcelain. The manufacturer's liquid showed higher translucency than Visual‐Eyes liquid; however, the color difference and the biaxial flexure strength were similar between the two liquids. The use of the Visual‐Eyes liquid is indicated in specific cases of complicated build‐ups. This study has targeted a material that has never been investigated before. The material was invented several years ago and updated to the new liquid, but its effect on porcelain is still unknown.
