The search for the ideal polishing agent for resin composite materials is still ongoing. A new polishing brush with abrasive bristles for polishing resin-based restorations was tested to determine if it polishes restorations, including those with concave surfaces, macrostructured occlusal surfaces, and textured surfaces, without destroying their delicate texture or microstructure.
The polishing effectiveness and the ultimate destructive potential of these brushes were assessed quantitatively and subjectively in vitro. In addition, the durability of the brushes after repeated use and autoclaving was also evaluated.
The brushes were nondestructive to resin-based restorative, enamel, dentin, and the restoration interface. They produced a shiny surface on resin-based restorative materials without destroying the surface texture. The abrasive brushes were autoclavable and demonstrated satisfactory durability, despite multiple heat sterilization cycles.
These brushes can be considered to be key products to polish concave surfaces, anatomically shaped occlusal surfaces, and textured surfaces without damaging the surface characteristics.
寻找树脂复合材料的理想抛光剂的工作仍在继续。一种用于抛光树脂基修复体的带有磨料刷毛的新型抛光刷进行了测试，以确定它是否能在不破坏修复体精细纹理或微观结构的情况下，对包括具有凹面、宏观结构咬合面和纹理表面的修复体进行抛光。
在体外对这些刷子的抛光效果和最终破坏潜力进行了定量和主观评估。此外，还评估了刷子在反复使用和高压灭菌后的耐用性。
这些刷子对树脂基修复体、牙釉质、牙本质和修复体界面无破坏作用。它们在不破坏树脂基修复材料表面纹理的情况下，使其表面产生光泽。尽管经过多次热灭菌循环，这种磨料刷仍可进行高压灭菌，且耐用性令人满意。
这些刷子可被视为用于抛光凹面、解剖形状的咬合面和纹理表面而不损害表面特性的关键产品。
