An in vitro comparison of the effect of various surface treatments on the tensile bond strength of three different luting cement to zirconia copings

Abstract

Aim:The aim of this study was to evaluate and compare the tensile bond strength of zirconia copings subjected to three different surface treatment methods and cemented with three different luting agents.Materials and Methods:Seventy-two extracted maxillary premolar teeth were prepared to receive zirconia copings milled using computer-aided design/computer-aided manufacturing technology, which were divided into 9 groups of 8 specimens each. Three surface treatment protocols such as hydrofluoric acid etch treatment, air abrasion with 110-μm aluminum oxide (Al2O3), and tribochemical silica coating (Rocatec) treatment were carried out, and copings were cemented with three luting agents such as resin-modified glass ionomer cement (RelyX luting 2), 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) resin cement (Panavia F 2.0) and 4-methacryloxyethyl trimellitic acid (4-META) resin cement (G-Cem). Tensile bond strength of the copings was tested in a universal testing machine. Zirconia copings fabricated on the prepared extracted tooth. After the three surface treatments and cementing the zirconia crowns with three luting agents tensile bond strength is tested. The mean and standard deviations (SD) were calculated for the nine groups using one-way ANOVA, followed by Tukey–Kramer post hoc using the SPSS software.Results:The ANOVA test showed that the measured mean bond strength values were 4.22 MPa (tribochemicalsilica coating and MDP resin), 2.71 MPa (air abrasion and MDP resin), 2.61 MPa (tribochemical treatment with META), and 0.66 MPa (RelyX with air abrasion). According to the pairwise comparison of Tukey's honestly significant difference test, significant differences were exhibited among all the groups (P < 0.05).Conclusion:Tribochemical silica coating in combination with 10-MDP and 4-META adhesive resins provided the maximum bonding for zirconia copings.

Comparative Evaluation of Tensile Bond Strength of Poly Ether Ether Ketone (PEEK) and Zirconia Copings Using Resin Cement with or without Adhesive: An In Vitro Study

“…The tensile bond strength of Zirconia with air abrasion shows a value of 2.71 ± 0.478, whereas when specimen were treated with HF acid they showed a tensile bond strength of 1.41 ± 0.338, and the third group surface treated with Al 2 O 3 particles followed by 30 µm silica coated Al 2 O 3 particles showed the value 4.22 ± 0.698. They concluded that air abrasion of the copings and META containing adhesive resin shows an increase in bond strength [16]. Visio.link is made up of MMA (Methyl methacrylate), PETIA (Pentacrythritoltriacrylate), dimethacrylate, and photoinitiator.…”

The Effect of Heat Treatment and Surface Energy Alteration on Controlling the Long Term Stability of the Zirconia-Resin Bond

“…[5][6][7][8][9][10][11][12][13][14] Different surface treatments showed success in improving the bond of Y-TZP to resin cements, with tribochemical silica coating showing better results when compared to other surface treatments such as air abrasion and acid etching. 7,[15][16][17][18] Several researches showed that the use of an MDP primer would have a positive impact on the initial shear bond strength (SBS) of the bonded zirconia samples. 7,11,14,16,17,[19][20][21][22][23][24][25] Although a high initial shear bond strength was achieved using a combination of surface treatments, priming agents and cements was successfully achieved 7,8,[14][15][16]26,27 , deterioration of the bond and significant decrease in the SBS was also noticed 7,8,14,23,25,28 Hence the need for testing different methods to maintain the original SBS or decrease the bond deterioration after aging was needed.…”
