抄録

To improve osteoblasts attachment to a porous implant such as artificial tooth root, plasma spray coating of hydroxyapatite (HA) has been attempted applying. However, plasma sprayed HA powders plugged up a way in holes of the porous structure which is important way of bone growth. To solve this problem, in this experiment, HA thin film 300nm thick was deposited by pulsed laser deposition (PLD) technique on the tooth root. HA thin film was reached easily to the depth of the porous structure. In 3 weeks after operation, the bone in-growth speed in HA-deposited tooth root was increased as compared with non HA-deposited one. In 5 weeks after operation, no particular difference between HA-deposited and non HA-deposited tooth roots was found. HA thin film deposition on a porous implant was effective in the improvement of osteoblast attachment.
