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.
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.
Overall shear bond strength values of luting cements defined in sandblasting groups were considerably higher than other surfaces (<.05). The cements can be ranked as AC > CI > PI > ZOC according to shear bond strength values for all surface treatment groups (<.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 (>.05).
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.
本研究旨在调查不同表面处理后，用于种植体固位修复体的粘结水门汀与钛试件之间的剪切粘结强度。
使用120个圆盘形试件。根据表面处理方式（未处理、喷砂和氧等离子体处理）将它们分为三组。测定试件的水接触角。根据所应用的水门汀类型，将试件进一步分为四个亚组（n = 10）：聚羧酸锌水门汀（Adhesor Carbofine - AC）、无锌临时水门汀（Temporary Cement - ZOC）、用于种植体固位修复体的非丁香酚临时水门汀（Premier Implant Cement - PI）和用于种植体粘结的非丁香酚丙烯酸 - 聚氨酯聚合物基临时水门汀（Cem Implant Cement - CI）。评估剪切粘结强度值。使用双向方差分析测试和回归分析对结果进行统计分析。
喷砂组中定义的粘结水门汀的总体剪切粘结强度值显著高于其他表面（P <.05）。对于所有表面处理组，根据剪切粘结强度值，水门汀可排序为AC > CI > PI > ZOC（P <.05）。表面处理（对照组、喷砂组和等离子体处理组）的水接触角分别为76.17°±3.99、110.45°±1.41和73.80°±4.79。回归分析显示不同表面的接触角与剪切粘结强度之间的相关性不强（P >.05）。
喷砂组和氧等离子体组中所有粘结水门汀的固位强度结果均高于对照组。氧等离子体处理可提高钛表面的粘附能力，而不会对钛结构造成任何机械损伤。
