Abstract

Coatings of hydroxyapatite (HA) and tricalcium phosphate/HA (TCP/HA) on titanium were fabricated by ion beam assisted deposition (IBAD). Significant effect of the Ca-P coatings on human Gingival Fibroblasts (HGFs) attachment and formation of type I collagen were found by using immunofluorescence microscope. TCP/HA and HA coatings exerted more HGFs attachment and collagen I formation. Comparing with HA coating, TCP/HA coating exhibited better responses during the late period of the tests. This investigation indicated that this surface modification method may enhance the biological seal at the cervical level of the titanium dental implants.
