Dental canular anchoring post for use in securely fixing a dental prosthesis has an organic structure with an inner core of greater radiographic opacity than the outer core

摘要

Canular post (10) which is radiographically opaque has a central zone (ZC) extending along the longitudinal axis made of composite material with an organic matrix (3), particles (5) and fibers (4). In the central zone the proportional particle volume is greater than the fiber volume, while in the annular peripheral zone (ZP), the volume proportion of fibers is greater than particles. This means that the radiographic opacity of the outer zone is less than that of the inner zone.
