28 June 2000 Loaded titanium implant with hydroxyapatite coat: histological observations
Author Affiliations +
The purpose of this study was to observe the response of surrounding tissues on long-term presence of coated titanium implants under loading. The protective layer based on hydroxy apatite was created by the method of pulsed laser deposition with KrF excimer laser on the kernel from pure titanium. The coating thickness was about 1 m. Implants were inserted into the mandible of minipigs up extracted premolars. After 14 weeks of healing without loading the metal-ceramic crowns were cemented and implants were moved in to the occlusion. Six months after the crown application the experimental animals were sacrificed and from the bone blocks with implants were manufactured microscopic ground sections. The implant position in the bone were determined by radiovisography. The bone structure around the implants were viewed in the microscope using transmitted light. Observation after six months long functional loading acknowledged the presence of newly formed bone around all implants. In no samples were found any inflammatory or regressive changes. Osseointegration of both surface types was similar.
