“…In previous studies, monolithic Zir was reported as wear-friendly with low antagonist wear, 12,13,23,44,53 attributed to its high microhardness. 11,12,32 In the present study, glazed Zir had lower volumetric loss than the PICN and was not significantly different from the other materials in terms of the volumetric loss, wear depth, and volumetric loss of enamel antagonists.…”

A restorative material should have wear properties similar to those of enamel, have adequate wear resistance, and minimize the wear of the antagonist teeth. Enamel wear has been reported to depend on the surface roughness, microhardness, frictional resistance, strength, texture, microstructural characteristics (porosity and grain size), and surface treatment (glazed or polished) of the antagonist. 3,5,10,[12][13][14]26,[28][29][30][31][32][33][34] An understanding of the wear mechanism and its controlling factors is critical for predicting long-term success. 3,35 Computer-aided design and computer-aided manufacturing (CAD-CAM) materials are increasingly used because of their favorable properties, 2,36-38 and monolithic restorations have become popular. [38][39][40][41][42] The absence of a veneer material may reduce the wear of the material and that of the antagonist. 3,30,43 Additionally, the ceramic type may affect wear. 3,[43][44][45][46][47] Presented at Turkish Dental Association (TDB) 24th International Dental Congress. 28 September, Ankara, Turkey, as oral presentation (In vitro wear resistance and surface properties of CAD-CAM materials).

“…Recently, high translucent, and ultra translucent zirconia (14,15) have been introduced to the dental field to overcome the opacious nature of zirconia restorations and develop close match colors of human teeth especially when it is used to restore esthetic region. The flexural strength of this material is 900-1400 MPa.…”

INTRODUCTION:Zirconia restorations present long-term clinical survival. Their low translucency makes them esthetically less than lithium disilicate (e.max CAD). The newly introduced ultra-translucent (UT) zirconia blocks improved the aesthetic problems of esthetic restorations. OBJECTIVES: To evaluate the translucency of UT zirconia restorations and to assess the effect of tribochemical silica coating (TSC) on its bond strength (BS) to the resin cement, using lithium disilicate as control. MATERIALS AND METHODS: Forty four disc-shaped specimens were fabricated and subjected to two main tests which were translucency test and shear bond strength test. Translucency groups: the specimens (10×0.5mm (n=20)) were divided into UTZT (ultra translusent zirconia) and LDT (lithium disilicate). Shear bond strength groups (SBST), specimens (5mm x 4mm (n=24)) were divided into UTZAA (ultra translusent zirconia treated by air abrasion), UTZSC (ultra translusent zirconia treated by TSC) and LDS ( lithium disilicate that was etched and silanated). RESULTS: Translucency results showed p value <0.001 which indicated higher translucency for the lithium disilicate than UT Zirconia. For SBST the results showed that, (UTZSC) provided the heighest mean BS (22.73 ± 3.91) followed by (LDS) (18.18 ± 1.56) and finally (UTZAA) provided the least BS (13.39 ± 4.31). CONCLUSIONS: Within the constraints of this study, UT zirconia showed less translucency than lithium disilicate. The use of silica coating improved the BS of zirconia.

“…Based on the ndings of few in vitro studies, it was found that polished full zirconia crowns caused least amount of enamel wear on naturally opposing teeth. [28][29][30] This is mostly because the polished full zirconia crowns are less abrasive to opposing teeth enamel due to its smooth surface 31 which in turn makes it more biocompatible when compared with other dental ceramics. 32 Nevertheless, more in vivo studies are needed to validate these ndings.…”
