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.

氧化锆因其卓越的美学特性而被广泛用作牙科植入物的材料。这项研究试图评估超声清洗后钛或氧化锆种植体基台对上皮附着的影响。将这些植入物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。另外，使用超声洁牙机清洁钛和氧化锆盘，观察表面形态变化，并测量表面上皮细胞附着的数量。最终，钛圆盘的表面比氧化锆的表面更容易损坏。超声波清洗在两种材料之间的上皮细胞附着数量没有差异。机械清洗后，氧化锆植入物基台表面的HRP反应时间比钛表面短。总之，氧化锆比钛硬，是用于上皮组织附着的更好选择。氧化锆比钛更适合用作植入物基台的材料。
