“…The results of the failure modes for the composites (Figure 6) supported the SBS test result. The results from the current study were of the same trend as previous researches [17][18][19][20]22,23].…”

“…Prior to cementation of the CAD/CAM composites, the majority of the manufacturers recommend roughening the fit surface of the restoration by alumina air-abrasion at 0.2-0.3 MPa pressure for 10 s, from a distance of 10 mm (e.g., Shofu Block HC Hard Instruction). There are a number of publications studying alternative surface treatment protocols including alumina air-abrasion at 0.1 MPa [19]; air-abrasion with glass beads at 0.4 MPa [15]; air-abrasion with the CoJet™ system [21,23]; or etching with hydrofluoric acid (HF) [17]. From the ones of recent researches, the alumina air-abrasion and HF are still by far the most promising methods to create surface roughness [24,25].…”

“…However, some critical issues have been pointed out on restoration using the CAD/CAM composite; fracture and debonding failures of the crown after delivery within a short time period [10][11][12][13]. Although many fundamental and clinical researches have been conducted to overcome these issues [14][15][16][17][18][19][20][21][22][23], it still remains an open research problem.…”

The purpose of this study was to clarify the influence of alumina air-abrasion on flexural and bond strengths of CAD/CAM composites. The flexural strength (FS) of two brands of commercial CAD/CAM composites was investigated by the three-point bending test using two specimen designs: the single-bar according to the ISO standard and the bonded-double-bar fabricated by bonding two bars with a resin cement. The bond strength between the composites and the resin cement was measured by a conventional shear bond strength (SBS) test. The FS of single-bar specimens was significantly decreased by the air-abrasion. For the FS of the bonded-double-bar specimen, on the other hand, there was no significant difference between the specimens with/without air-abrasion. The SBS for the composites was significantly increased by air-abrasion. The results suggest that alumina air-abrasion improves the SBS of the composites while weakening its FS. Contrarily, the FS of the air-abraded composite did not decrease when the composites were bonded with the resin cement.

“…Moreover, the restorative material's translucency shown by the amount of reflection and scattering of light is another factor (4)(5)(6)(7). Together with all-ceramic materials, resin-based cements are considered an essential part of the success and quality of esthetic treatments (8)(9).…”

INTRODUCTION: The color stability of the resin-based cement employed for the cementation procedure may be as important for the long-term clinical success of the restoration as the mechanical properties of the veneer. OBJECTIVES: The aim of this study was to evaluate the effect of different polymerization modes of resin cements and ceramic thicknesses on the color stability of feldspathic CAD/CAM veneers. MATERIALS AND METHODS: Sixty-four sound human maxillary central incisor teeth were divided according to ceramic veneer thickness used into two main groups (n = 32); Group I; 0. 5 mm ceramic thickness and Group II; 1 mm ceramic thickness, each group was then subdivided according to the type of resin cement received (Light cure LC or Dual cure DC) into four sub groups of 16 specimens each: Group I A:(0.5 + LC); Group I B:(0.5 + DC); Group II A:(1 + LC); Group II B (1 +DC). Sixty four Ceramic discs were prepared; for group I, 32 discs of diameter 7 mm and height 0.5mm while for group II, 32 discs of diameter 7mm and height 1mm. The shade was measured using digital spectrophotometer at 3 different time intervals. RESULTS: Ceramic thickness alone revealed statistically significant effect on the ∆E values of all groups (p ≤ 0.05), irrespective of the type of the resin cement. The highest mean ∆E values were recorded in group I A and the lowest ∆E values were recorded in group II B .There was statistically significant difference in ∆E 2 between groups IA and IB. CONCLUSIONS: All studied cements showed ∆E within clinically acceptable range in both dual cure and light cure resin cements. Increasing ceramic thickness can serve to mask the underlying color change.

“…Therefore, the use of silane-containing adhesive systems decreases the number of operation steps of adhesive cementation. 18 A number of studies 5,9,[11][12][13]16 have investigated the bond strength of indirect restorative materials to resin cement however there is a lack of literature 16,19,20 comparing the bond strengths of CAD/ CAM resin nano ceramic or ceromer to resin cement. The aim of this study was to evaluate the effects of various surface treatment procedures on the micro-tensile bond strength (MTBS) of two different indirect restoration materials to resin cement.…”

Objectives: The purpose of this study was to evaluate the effects of different surface treatments on the micro-tensile bond strength (MTBS) of two different indirect restoration materials (resin nano ceramic CAD/CAM material [Lava Ultimate, 3M ESPE]; ceromer material [Estenia C&B, Kuraray Medical]). Materials and Methods: Specimens were prepared from each test material in dimensions of 3×10×10 mm. The specimens were divided into five different surface treatment groups: group 1 (control [C]), no treatment; group 2 (acid etching [A]); group 3 (acid etching + universal adhesive [AA]); group 4 (sandblasting [S]); and group 5 (sandblasting + universal adhesive [SA]). The prepared specimens were cemented to composite parts (Filtek Z250 Universal Restorative, 3M ESPE) of the same size using dual-cure adhesive resin cement (Panavia F2.0, Kuraray Medical). A total, 100 bar-shaped specimens (6×1×1 mm) were cut using a low-speed diamond saw (n=10 in each group). The MTBS test was performed in all groups (Shimadzu AG-50 kNG, Kyoto, Japan, 1 mm/min). Data were analyzed using a two-way analysis of variance (ANOVA) and Tukey's multiple comparison tests at a significance level of p<0.05. Results: The MTBS values were significantly influenced by the type of restorative material and surface treatment (p<0.05). There were statistically significant differences between the materials and surface treatments procedures (p<0.05). For Lava Ultimate and Estenia C&B materials, the highest MTBS value was obtained in the SA surface treatment (p<0.05) and the lowest MTBS value was obtained in the control groups (p<0.05). Conclusions: The application of silane-containing universal adhesive material after sandblasting was the ideal surface treatment for both materials.
