Aim of study was to evaluate osseointegration of the KrF laser hydroxylapatitecoated titanium alloy Ti6A14V dental implants. For deposition KrF excimer laser in stainless-steel deposition chamber was used. Thickness of HA films were round 1 mm. Mini-pigs wereused in this investigation. Implants were placed vertically into the lower jaw. After 14 weeksunloaded osseointegration the metal ceramic crowns were inserted. The experimental animalswere sacrificed (a half of year post insertion). The vertical position of implants was controlledwith a radiograph. Microscopic sections were cut and ground. Sections were viewed usingmicroscope with CCD camera. Six months osseointegration in lower jaw confirmed by allimplants presence of newly formed bone around the all implants. In case of laser-depositedcoating the layer of fibrous connective tissue was seen only seldom. In the control group(titanium implant without cover) the fibrous connective tissue was seen between implant andnewly formed bone.
Key words: dentistry – dental implants – hydroxylapatite – titanium
