Patent ID: 8329464

Claim:
An implant surface treatment method to analyze the effects of surface treatment on cell growth, comprising the steps of: (a) treating one portion of a surface of a titanium (Ti) metal of an implant through a sandblasted, large-grit, acid-etched (SLA) surface treatment to obtain roughness; (b) treating a second portion of a surface of a titanium (Ti) metal of an said implant through a sandblasted, large grit, acid etched (SLA) surface treatment and using a calcium-rich phosphate salt to clean and be embedded into said Ti metal through secondary grit-blasting, wherein the calcium-rich phosphate salt provides calcium ions and phosphate ions; (c) leaving a third portion of the surface of a said titanium metal implant untreated; (d) culturing a bone cell, a fibroblast and an epidermal cell on the surface of the implant, wherein said bone cell is MC3T3-E1, said fibroblast is NIH 3T3 and said epidermal cell is XB-2, to identify the amount of sandblasting and cleaning to result in activation of growth of said epidermal cell and inhibition of growth of said fibroblast on the third portion of the implant surface, and activation of growth of said bone cell and inhibition of growth of said fibroblast on the second portion of the implant surface; and (e) analyzing growth of each of the cell types on the treated implant.
