目的
比较不同表面处理对二硅酸锂微晶玻璃剪切粘结强度和表面粗糙度的影响。
方法
根据制造商的说明制备60个二硅酸锂陶瓷样品，并根据表面处理分为六组：对照（C）、5%HF蚀刻20秒和60秒（E20、E60）、Monobond蚀刻和Prime蚀刻（MEP）、Nd:YAG（ND）和Er:YAG（ER）激光照射。除 MEP 组外，所有组均用通用引物处理。自粘树脂水泥粘合到所有组上。使用万能试验机测量样品的剪切粘合强度，同时使用轮廓仪测量表面粗糙度。
结果
Kruskal-Wallis 和 Mann-Whitney U 检验显示显着差异 (P< 0.05)。 E60组的剪切粘结强度高于其他组，而MEP和ER组的表面粗糙度最高。
临床意义
Monobond Etch & Prime 可能是获得足够粘合强度值的有用方法。
PURPOSE
To compare the influence of various surface treatments on the shear bond strength and surface roughness of lithium disilicate glass-ceramics.
METHODS
60 lithium disilicate ceramic samples were prepared according to the manufacturers' instructions and were divided into six groups according to the surface treatment:Control (C), 5% HF etching for 20 and 60 seconds (E20, E60), Monobond Etch & Prime etching (MEP), Nd:YAG (ND) and Er:YAG (ER) laser irradiation. All groups were treated with a universal primer except group MEP. A self-adhesive resin cement was bonded to all groups. The shear bond strengths of the specimens were measured using a universal testing machine while surface roughness was measured using a profilometer.
RESULTS
Kruskal-Wallis and Mann-Whitney U tests revealed significant differences (P< 0.05). The shear bond strength of group E60 was higher than the other groups while surface roughness of groups MEP and ER were highest.
CLINICAL SIGNIFICANCE
Monobond Etch & Prime might be a useful method in order to obtain adequate bond strength values.
