The surface treatment for zirconia generally involves sandblasting and the application of primers for favorable bond strength between the surface and resin. However, sandblasting causes the microcracking and chipping of the zirconia surface. To overcome these challenges, the metallization of the zirconia surface was performed. Ti and Au were sputtered on yttria stabilized zirconia (YSZ) disks and heated to 800 ℃ for 15 min in air. These disks were bonded to stainless-steel rods using resin cement. Then, shear bond strength tests were performed using an Instron-type testing machine. The shear bond strength of the Ti sputtering group was significantly higher than that of the other groups. According to the results of X-ray photoelectron spectroscopy and electron probe microanalysis, the Ti-sputtered YSZ surface contained both sub-titanium oxide and titanium oxide before heating. Sub-titanium oxide was converted to titanium oxide by heating. These results suggest that metallization using Ti is effective for zirconia surface treatment to improve the shear bond strength between YSZ and resin cement. This metallization technique for YSZ has potential in clinical applications.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "Journal of Functional Biomaterials. 2021, 12(4), 62.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大院博(歯)第501号", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "甲第5015号"}]}, "item_6_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.3390/jfb12040062", "subitem_relation_type_select": "DOI"}}]}, "item_6_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2021 by the authors.
