Outline of Final Research Achievements

The aim of this study is to prove the hypothesis that Ca modificated titanium implants and Ca modificated acid etching titanium implants made by using novel Ca modification method that our study group developed show increased new bone formation and high stability after being implanted to organism by animal study.
As a result, Ca modificated acid etching titanium implants showed high mechanical stability, increased new bone formation around implants by histomorphometric evaluation. Moreover, Ca modificated acid etching titanium implants demonstrated no significant accumulation of metal ions. Collectively, these findings suggest the usefulness of Ca modificated acid etching titanium implants for biomedical applications.
