AIM
The aim of this study was to evaluate how different post-surface treatments affect the ability of luting cement to bond three different dental post materials to a resinous surface.
MATERIALS AND METHODS
The study analyzed a total of 108 posts categorized into three main groups: stainless steel, cast, and fiber posts. Next, the core group was divided into four subgroups ( = 9) according to the type of surface treatment applied: no surface treatment (NS), silanization (SZ), sandblasting (SB), and sandblasting plus silanization (SBSZ).
RESULTS
Stainless steel posts exhibited the lowest bond strength, whereas fiber posts demonstrated the highest shear bond strength. When it comes to surface treatments, dental post-surfaces treated with sandblasting have been found to exhibit the highest bond strength, outperforming other methods.
CONCLUSION
Comparing all methods of surface modification, sandblasting with 50 um AlO particles demonstrated the strongest connection.
目的
本研究的目的是评估不同的表面处理如何影响粘结水门汀将三种不同的牙科桩材料粘结到树脂表面的能力。
材料与方法
本研究共分析了108根桩，分为三个主要组：不锈钢桩、铸造桩和纤维桩。接下来，根据所应用的表面处理类型，核心组又分为四个亚组（每组 = 9）：未进行表面处理（NS）、硅烷化处理（SZ）、喷砂处理（SB）和喷砂加硅烷化处理（SBSZ）。
结果
不锈钢桩的粘结强度最低，而纤维桩的剪切粘结强度最高。在表面处理方面，已发现经喷砂处理的牙科桩表面表现出最高的粘结强度，优于其他方法。
结论
比较所有表面改性方法，用50微米氧化铝颗粒进行喷砂处理显示出最强的粘结力。
