Effect of different surface treatments on the shear bond strength of luting cements used with implant-supported prosthesis: Anin vitrostudy

Abstract

The aim of this study was to investigate the shear bond strength of luting cements used with implant retained restorations on to titanium specimens after different surface treatments. MATERIALS AND METHODS. One hundred twenty disc shaped specimens were used. They were divided into three groups considering the surface treatments (no treatment, sandblasting, and oxygen plasma treatment). Water contact angle of specimens were determined. The specimens were further divided into four subgroups (n=10) according to applied cement types: polycarboxylate cement (Adhesor Carbofine-AC), temporary zinc oxide free cement (Temporary Cement-ZOC), non eugenol provisional cement for implant retained prosthesis (Premier Implant Cement-PI), and non eugenol acrylic-urethane polymer based provisional cement for implant luting (Cem Implant Cement-CI). Shear bond strength values were evaluated. Two-way ANOVA test and Regression analysis were used to statistical analyze the results. RESULTS. Overall shear bond strength values of luting cements defined in sandblasting groups were considerably higher than other surfaces (P<.05). The cements can be ranked as AC > CI > PI > ZOC according to shear bond strength values for all surface treatment groups (P<.05). Water contact angles of surface treatments (control, sandblasting, and plasma treatment group) were 76.17° ± 3.99, 110.45° ± 1.41, and 73.80° ± 4.79, respectively. Regression analysis revealed that correlation between the contact angle of different surfaces and shear bond strength was not strong (P>.05). CONCLUSION. The retentive strength findings of all luting cements were higher in sandblasting and oxygen plasma groups than in control groups. Oxygen plasma treatment can improve the adhesion ability of titanium surfaces without any mechanical damage to titanium structure.

Investigation of the Effect of Mouthwash on Bonding Temporary Crown Materials with Various Temporary Cements

“…17 As Protemp is based on bis-acrylic composite, it has been advised not to use a cement that contains eugenol should not be used. 29 The findings of this study support this recommendation. It was also found in this study that the sandblasting surface treatment applied to the bisacryl composite-based temporary restorative material increased the bonding of the eugenol-containing cement.…”

“…This finding is consistent with studies that have indicated that sandblasted surfaces create micro-retention areas by enhancing the adhesion of cements through mechanical locking. [27][28][29] In a study assessing the retentive properties of various temporary cements on temporary crowns, it was found that calcium hydroxide cements exhibited greater retention on polymethylmethacrylate resins compared to Tempond (Ca(OH)2: 795 kPa; Temp-Bond: 714 kPa). 30 The study also revealed that the shear bond strengths of calcium hydroxide cements, with the exception of CAD/CAM Group 3Bc and Imicryl Group 3Bc, were higher than those of Tempbond.…”

Mapping Bone Marrow Cell Response from Senile Female Rats on Ca-P-Doped Titanium Coating

“…Developing a surface morphology that accelerates bone healing is one of the top interests in materials sciences and biotechnology. The high predictability and good results obtained in daily clinical practice through SLA surface treatment on Ti and Ti alloy implants, highlight this texturing method as one of the main techniques used in the market [ 11 , 58 , 59 , 60 , 61 , 62 ].…”

Cytotoxicity and Bonding Property of Bioinspired Nacre-like Ceramic-Polymer Composites

“…The poor bonding strength of the Control group may be due to the lack of resin phase. However, the direct relationship between the bonding strength and contact angle cannot be determined because of the confounding of hydrophilicity, wettability, and surface energy ( Degirmenci and Saridag, 2020 ). Ozcan et al ( Özcan et al, 2008 ) pointed out that MDP monomer could be directly bonded with metal oxides.…”
