摘要：
PURPOSE: A surface roughness increasing method of a titanium implant is provided to increase adhesive strength and to redouble the bone conduction speed by utilizing 1-30% of a residual hydroxyapatite (HA) isolator, thereby reducing the speed of bone integration for a patient after a surgical procedure. CONSTITUTION: A surface roughness increasing method of a titanium implant comprises the following steps. An implant type base metal, which is made of Ti or low carbon Ti alloy and composed 0.8-8.0 &mu；m of the controlled average illuminance of a surface, is prepared (S10). Particles of hydroxyapatite (HA) collide with the implant type base metal at low temperature and high speed (S20). The implant type base metal is precipitated in liquid, and washed (S30). [Reference numerals] (S10) Step of preparing an implant type base metal with an average illuminance of the surface of 0.8-8.0&mu；m, which is prepared by Ti or low carbon Ti alloy； (S20) Step of colliding hydroxyapatite(HA) particles with the implant type base metal at low temperature and high speed； (S30) Step of precipitating the implant type base metal in liquid and washing티타늄 임플란트의 표면거칠기 증가방법이 개시된다. 본 발명에 의한 티타늄 또는 저탄성 티타늄 합금으로 제조되며, 표면부 평균조도가 0.8~8.0㎛로 조절된 임플란트형 기지금속을 제공하는 단계, 상기 임플란트형 기지금속의 표면에 수산화 아파타이트(hydroxyapatite； HA) 입자를 저온 고속 충돌시키는 단계, 및 상기 임플란트형 기지금속을 액체에 침적하여 수세하는 단계를 포함한다.
