PURPOSE: A surface processing method and a dental implant which is surface-treated with the same are provided to enhance biocompatibility of materials like hydroxyapatite. CONSTITUTION: A surface processing method comprises the following steps: forming titania nanotube on the surface of dental implant(S120); converting amorphous phase titania nano-tube into crystal phase by using thermal process of the dental implant (S130); performing ultrasonic wave processing in ethanol after pre-treating the carbon nano-tubes (S160); and coating the dental implant surface with carbon nano-tube by electrolyzation after the platinum and dental implant are precipitated in the ethanol (S170). [Reference numerals] (AA) Start; (BB) End; (S110) Removing oxidized film of dental implant; (S120) Forming titania nanotube on the surface of dental implant; (S130) Thermal processing of the dental implant; (S140) Manufacturing suspended solution by mixing carbon nano-tube with acid solution; (S150) Agitating, neutralizing and filtering the suspended solution; (S160) Dispersing the filtered carbon nano-tube; (S170) Coating the dental implant with carbon nano-tube
