Precision dentistry attachment

摘要

The fixed primary section consists of a block (8) of any desired shape. This contains two opposite taper bores (10), which are formed extra-coronarily. These can be open at the side, but not as far as the respective equator, so as to provide mechanical retension resistant to lateral extracting forces. The primary section can taper in the insertion direction, working (sic) in conjunction with the taper bores. The rear locking screw (5) can protrude from the secondary section (1), allowing gluing via the vertical recesses of the secondary section to the removable false tooth and securing it in all directions.
