“…An example is Celtra Duo which is a zirconia reinforced lithium silicate CAD/CAM material that may be optionally heat treated. Although heat treatment is not necessary for crystallization of the material, flexural strength of fired Celtra Duo has been reported to be considerably greater than the unfired as milled material . The unfired as milled version of Celtra Duo was used in this article to test their fracture resistance when used as an endocrown restoration polished and adhesively incorporated immediately after milling without further heat treatment.…”

“…According to a previous study, Celtra DUO is a strong, stiff, hard CAD/CAM restorative material due to its high flexural strength, elastic modulus, and Vickers hardness values (22). Furthermore, its wear pattern has been reported to be extremely smooth (22,23). We consider that these properties have contributed to the maintenance of high surface gloss and low surface roughness even after prophylaxis in Celtra DUO.…”

BackgroundThis study aimed to evaluate the effect of dental prophylaxis on the surface gloss and roughness of different indirect restorative materials for computer-aided design/computer-aided manufacturing (CAD/CAM): two types of CAD/CAM composite resin blocks (Shofu Block HC and Estelite Block) and two types of CAD/CAM ceramic blocks (IPS Empress CAD and Celtra DUO).Material and MethodsAfter polishing the CAD/CAM blocks and applying prophylaxis pastes, professional dental prophylaxis was performed using four different experimental protocols (n = 5 each): mechanical cleaning with Merssage Regular for 10 s four times (Group 1); four cycles of mechanical cleaning with Merssage Regular for 10 s and Merssage Fine for 10 s (Group 2); four cycles of mechanical cleaning with Merssage Regular for 10 s and Merssage Fine for 30 s (Group 3); and mechanical cleaning with Merssage Fine for 10 s four times (Group 4). A glossmeter was used to measure surface gloss before and after mechanical cleaning, and a contact stylus profilometer was used to measure surface roughness (Ra).ResultsPolishing with prophylactic paste led to a significant reduction in surface gloss and increase in surface roughness among resin composite blocks, whereas the polishing-related change in surface gloss or roughness was smaller in Celtra DUO, a zirconia-reinforced lithium silicate block.ConclusionsChanges in surface gloss and roughness due to polishing with a prophylactic paste containing large particles were not improved by subsequent polishing with a prophylactic paste containing fine particles. Key words:CAD/CAM, professional dental prophylaxis, prophylactic paste, surface gloss, surface roughness.

“…Several studies have analyzed the in vitro wear resistance of restorative materials opposing either human enamel antagonists or dedicated artificial abraders. [1][2][3][4] The abrasiveness of gold-based alloys, resin composites, feldspathic porcelains, glass ceramics, and polycrystalline zirconia-based materials toward tooth hard tissues has also been the subject of extensive investigation. [5][6][7][8][9] In previous research, dental gold-based alloys showed wear characteristics very similar to human enamel.…”

“…[5][6][7][8][9] In previous research, dental gold-based alloys showed wear characteristics very similar to human enamel. 1,2 Nevertheless, in spite of their excellent marginal accuracy 10,11 and uncontested mechanical/ tribological properties, 12 an increasing demand for better esthetics persuaded clinicians to withdraw full-gold restorations in favor of alternative toothcolored materials.…”

The purpose of the present in vitro study was to compare the two-body wear resistance of a type 3 gold alloy (Aurocast8), two lithium disilicate glass ceramics (IPS e.max CAD and IPS e.max Press), a heat-pressed feldspathic porcelain (Cerabien ZR Press), an yttria-stabilized tetragonal zirconia polycrystal ceramic (Katana Zirconia ML), and three heat-cured composite resins (Ceram.X Universal, Enamel Plus Function, and Enamel Plus HRi) opposing antagonistic cusps made out of the same restorative materials. Ten 6-mm-thick samples and 10 cusp-shaped abraders were manufactured with each test material (n=10) according to standard laboratory procedures. All sample/antagonist pairs made out of the same material were subjected to a two-body wear test in a dual-axis chewing simulator for up to 120,000 loading cycles. The total vertical wear (mm) and the total volumetric loss (mm) for each sample/antagonist pair were calculated. Data were statistically analyzed using one-way analysis of variance tests. The total vertical wear for the gold alloy was not significantly different compared to Ceram.X Universal, Enamel Plus Function, IPS e.max CAD, and Cerabien ZR Press. Significantly increased wear values were observed for Enamel Plus HRi and IPS e.max Press. The lowest values for total vertical wear and volumetric loss were recorded on the monolithic zirconia.
