Abstract

The fixation between a beads-type porous-surfaced dental implant and a surrounding bone is dependent on 3-dimensional anchoring effect which new bones develop into a porous structure. The speed of a bone ingrowth into the porous structure and the good fixation to bone is strongly related to biocompatibility of the implant. To impart a functional fixation by biointegration to the implant, in this study, a pulsed laser deposition (PLD) technique was used to form 300 nm thick hydroxyapatite (HA) film even on the depths of the porous structure. Through X-ray diffraction (XRD) and energy dispersive X-ray spectrometry (EDX) analysis, it was found that HA was crystallized and was deposited on the depths of interconnecting pores of complicated shape. The implants were placed into posterior regions of completely edentulous mandible of a canine. The bone ingrowth condition was scanned by CT scanner. In three weeks after operation, the bone ingrowth speed in the HA-deposited implant was increased as compared with the non-HA-deposited one. In five weeks after operation, no particular differences on the bone ingrowth between the HA-deposited and non-HA-deposited implants were found. HA thin film deposition on a porous-suerfaced implant was effective in the improvement of functional bone fixation.
