First Claim
Patent Images
1. A method of increasing the hydrophilicity of an implant to be implanted into living bone, the method comprising the acts of:
- depositing non-toxic sodium lactate salt residuals on the surface of the implant by immersing at least a portion of the implant in a solution including sodium lactate; and
drying the implant,wherein the contact angle formed by a deionized water droplet on the surface of the implant ranges from about 5°
to about 65°
