氧化锆因其上级美观性而被广泛用作牙科植入工作中的材料。本研究旨在评价超声清洗后钛或氧化锆种植体基台对上皮附着的影响。将这些种植体插入大鼠上颌第一磨牙的拔牙窝中。然后，测量辣根过氧化物酶（HRP）反应的长度。此外，钛和氧化锆磁盘使用超声波除垢器清洗，表面形态变化进行了观察，并测量上皮细胞附着到表面的数量。最终，钛金属圆盘的表面比氧化锆圆盘的表面更容易损坏。两种材料经超声清洗后，上皮细胞附着数量无差异。机械清洗后，氧化锆种植体基台表面的HRP反应时间短于钛种植体基台表面。总之，氧化锆比钛硬，是用于上皮组织附着的更好选择。氧化锆比钛更适合作为种植体基台的材料。
Zirconia is widely employed as a material during dental implant work because of its superior esthetics. This study sought to evaluate the impact of titanium or zirconia implant abutments on epithelial attachments after ultrasonic cleaning. These implants were inserted into the extraction socket of rat maxillary first molars. Then, the length of the horseradish peroxidase (HRP) reaction was measured. In addition, titanium and zirconia disks were cleaned using an ultrasonic scaler, surface morphology changes were observed, and the number of epithelial cell attachments to the surface was measured. Ultimately, the surfaces of the titanium disks were easier to damage than those of the zirconia ones. There was no difference in the number of epithelial cell attachments between the two materials with the ultrasonic cleaning. The length of the HRP reaction was shorter on the zirconia implant abutment surface than on the titanium one after mechanical cleaning. In conclusion, zirconia is harder than titanium and a better choice for use in the epithelial tissue attachment. Zirconia is more suitable as a material for implant abutments than titanium.
