osseointegration

most of the implants in the market are composed of commercially pure titanium

implants purely from zirconia, a material that appears to offer similar patterns of osseointegration with titanium

osseointegration between implants with smooth surface and two different types of moderately rough surface showed a significant advantage for the rough surfaces in terms of the bone-to-implant contact and the quantity of osseointegration

Metaphysics means nothing but an unusually obstinate effort to think clearly.

Believe me, it jabs you. When you're on the side of buses and New York loves you, you love to go out there every night. It's like a race. Curtain opens, out you go, and New York is yours.

If we are surrounded by the trivial and the vicious, it is all too easy to make our peace with it.

The eternal silence of these infinite spaces frightens me.
