Production of thin calcium phosphate coatings from glass source materials

Calcium phosphate (CaP) coatings, from 40,000 to 200,000 nm thick, on titanium and titanium alloy substrates, were produced using radio frequency (RF) sputtering. Such coatings on dental implants have the potential for improving initial bone ingrowth rates. The success of these coatings may allow th...

Summary:Calcium phosphate (CaP) coatings, from 40,000 to 200,000 nm thick, on titanium and titanium alloy substrates, were produced using radio frequency (RF) sputtering. Such coatings on dental implants have the potential for improving initial bone ingrowth rates. The success of these coatings may allow the movement from two stage implant systems to single stage implant systems, significantly reducing the time required for healing and fixture placement. Glass source materials were developed for the RF sputtering facility and the resultant coatings were characterized and compared to coatings sputtered from a conventional plasma sprayed hydroxyapatite (HA) source material. The coatings were characterized according to their chemistry, crystalline orientation, and residual strain.
