 note = {P(論文), Clinical sudies of current implant systems and their characteristics such as survival rates were reviewed. In addition, trends in fixture-abutment connections, aesthetic components, and tissue management were considered. The survival rate of the implant systems was around 90% even though some systems only showed long-term (more than five years) implant survival and cervical bone resorption around implants. The recent trend of fixture-abutment connections have been shifting from external to internal connections to protect from screw loosening and to maintain biological sealing from bacterial infections. With regard to aesthetic restoration, many types of abutments have been considered such as anatomical abutments and fixture impression techniques. The major procedure for the connection between abutment and super-structure in the systems is cementing, not screw retention, especially among general practitioners, evaluated from the sales figures of the components.},
