Due to the research from many angles, dental implants have been widely used in practice.
From the aspect of material science, they are generally categorized as metallic implants and ceramic implants. Among them, implants utilizing pure titanium or hydroxyapatite have gained a high reputation for their superior biocompatibility and comparable stability in bones when applied in practice. Taking advantage of these characteristics, endosseous implants of titanium blade which are coated with HAP alumina by plasma sprayed technique, have been developed.
This study, through biological testing, aims to compare changes and reactions of bone in case of pure titanium blade and HAP alumina coated blade-vent implants.
We made the implant material free standing and adjusted the implants head in order to avoid occlusal stress and other functional pressures inside the mouth. One month after the blade insert,the bone in contact with the blade was cut out and analyzed by diffuse reflectional infrared spectrophotometry using on FT/IR-7000 infrared spectrophotometer (Japan Spectroscopic, Co.,Ltd.). The study results including spectral differences with the osseous bone are described in this paper.
