The purpose of this experimental study was to observe the response of surroundingtissues to long-term presence of coated titanium implants under loading. The protectivelayer based on hydroxylapatite was created by the method of pulsed laser deposition with KrFexcimer laser on the kernel from titanium alloy. The coating thickness was about 1 mm.Implants were inserted into the mandible of minipigs up extracted premolars. Up 14 weeks ofhealing without loading the metal-ceramic crowns were cemented and implants were movedinto the occlusion. Six months after the crown application the experimental animals weresacrificed and from the bone blocks with implants were manufactured microscopic groundsections. The implant position in the bone was determined by radiovisiography. The bonestructure around implant was viewed in microscope using the transmitted light. Observationafter six months long functional loading acknowledge the presence of newly formed bone aroundof all implants. At none of samples were found any osteoclasts, macrophages or regressivechanges.
Key words: dentistry – dental implants – hydroxylapatite – titanium – histology
