| 英文摘要 | surface microstructure and chemical composition of the implant are very important for its osseointegration in vivo. in this paper, a hierarchical micropattern covered with calcium phosphate (ca/p phase) was obtained on titanium (ti) implant surface by femtosecond lasers (fsl) irradiation in hydroxyapatite suspension. the hierachical micropattern as well as ca/p phase increased osteoblastic cell adhesion. higher expression of osteogenic markers (osteocalcin, osteopontin, and runt related transcription factor-2) on the surface treated by fsl of 2.55 j/cm(2) indicated the favorable effect of laser treatment on cell differentiation. in vivo studies were carried out to evaluate the effect of laser treatment and ca/p deposition on the osseointegration. it showed that the binding capacity between bone and fsl-treated ti implants was obviously stronger than that between bone and polished or sand blasting and acid etching (sla) ti implants. bone trabecula surrounded the fsl-treated implants without fibrous tissue after 8-week implantation. also, higher bone mineral density was seen surrounding the fsl-treated implants. our in vitro and in vivo studies demonstrated that the fsl induced micropattern and ca/p phase had positive effects on the acceleration of early osseointegration of ti implants with bone tissue. |
