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.
由于其卓越的美学效果，氧化锆在种植牙手术中被广泛用作一种材料。本研究旨在评估超声清洁后钛或氧化锆种植体基台对上皮附着的影响。将这些种植体植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，使用超声洁牙器清洁钛盘和氧化锆盘，观察表面形态变化，并测量附着在表面的上皮细胞数量。最终，钛盘的表面比氧化锆盘的表面更容易受损。超声清洁后，两种材料上皮细胞附着的数量没有差异。机械清洁后，氧化锆种植体基台表面的HRP反应长度比钛基台表面的短。总之，氧化锆比钛更硬，是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。
