Less friction around cortical bone
promotes less bone loss.
Ra : 2.0~2.5㎛ Stimulate Osseointegration
with ideal Ra.2.0~2.5 ㎛ promotes not only rapid
osseointegration but also long-term statibility.

Titanium oxide lm is typically consist of TiO, TiO3, TiO2. The most stable form is TiO2.
Size of 1~10um, micro scale of roughness stimulates attachment and separation of osteoblast and accelerates building of
extracellular matrix(ECM) and mineralization which helps to create faster osseointegration reaction.
Rough surfaces increase coherence between surface of implant and mineralized bone. Hansson S, Norton M. theoretical
approached and has reported that depth of 1.5um, 3~5um in diameter hemisphere pit is ideal for perfect roughness.
