Abstract

Abstract:

BACKGROUND: Any surface treatments should improve the bond strength of yttria-stabilized tetragonal zirconia polycrystal ceramics without damaging the original strength. Currently, there is no information about the influence of glaze technology on the bond strength of yttria-stabilized tetragonal zirconia polycrystal ceramics, and its influence on the material strength is unclear.

OBJECTIVE: To evaluate the effect of glaze technology on the mechanical behavior of yttria-stabilized tetragonal zirconia polycrystal ceramics and on the bond strength with resin cements.

METHODS: Yttria-stabilized tetragonal zirconia polycrystal ceramics specimens were prepared and randomly divided into four groups: group A: the surface was not treated; group B: sandblasting with 110 μm Al₂O₃ particles; group C: glaze + hydrofluoric acid etching; group D: glaze + hydrofluoric acid etching + silanization. The surface morphology, surface roughness, phase transformation, elemental composition, shear bond strength and flexural strength of zirconia specimens after surface treatments were tested.

RESULTS AND CONCLUSION: (1) The surface roughness of treatment groups increased obviously, whose descending order was group C (0.62±0.01) μm > group D (0.55±0.02) μm > group B (0.11±0.02) μm > group A (0.05±0.01) μm (P < 0.05). (2) The surface of specimens in the group B contained 2.2% monoclinic zirconia, while the content of other groups was zero. (3) In addition to elements of Zr and O, there was 6.49% Al element in the group B specimens, and 18.67% and 25.78% Si element in the groups C and D specimens, respectively. (4) The shear bond strength in the groups A, B, C and D was (3.11±0.40), (4.23±0.45), (6.62±0.60) and (10.46±0.83) MPa, respectively (P < 0.05). (5) The three-point flexural strength in the groups A, B, C and D was (961.07±75.53), (1 234.73±114.09), (1 024.28±120.51), and (1 036.09±80.10) MPa, respectively, among which the multiple comparison of groups A, C and D showed no significant difference (P > 0.05). (6) The effect of glaze technology on improving the flexural strength of yttria-stabilized tetragonal zirconia polycrystal ceramics is not as obvious as that of sandblasting, but the bond strength between tetragonal zirconia polycrystal ceramics and resin cements can be significantly improved with hydrofluoric acid etching and silanization after glaze.
