An abutment coated with a titanium oxide layer is provided to improve bonding with an artificial crown, without necessarily using a metal cap but simply by using an anodizing method. An abutment(1) comprises a titanium oxide layer(100) having a thickness of 0.5-2.0 micrometers and an artificial crown. The oxide layer is obtained by anodizing the abutment body. To obtain the oxide layer, a micro-arc oxidizing electrolyte where the abutment is soaked is prepared. Then, the electrolyte is poured into an electrolyzer, and abutments are installed at an anodizing jig. With the abutments being combined with the anodizing jig, 250-290V DC is applied to form an oxide layer. Finally, the abutment coated with the oxide layer is rinsed with distilled water and dried. |
