FUNCTIONAL IMPLANT

摘要

A functional implant includes: a fixture; an abutment coupled to the upper portion of the fixture using a bolt; and a crown coupled to the abutment coupled to the fixture, the crown having a crown body concave on top thereof, an abutment insertion recess formed inside the crown body to be open on the underside of the crown body, and a coupling guide portion formed on an inner peripheral wall of the abutment insertion recess and having a scratch surface formed on the surface of the inner peripheral wall, a silica layer bonded to the scratch surface, a zirconia primer layer coated onto the silica layer, and a resin bonded to the zirconia primer layer. The crown is detachably coupled to the abutment through press-fitting, thereby allowing easy detachment and smooth repair and correction. The crown is made using milling, thus reducing errors to ensure good fitness and passivity.

1. A functional implant comprising:
a fixture (30); an abutment (20) coupled to the upper portion of the fixture (30) by means of a bolt B; and a crown (10) coupled to the abutment (20) coupled to the fixture (30) and having a crown body (11) concave on top thereof, an abutment insertion recess (12) formed inside the crown body (11) in such a manner as to be open on the underside of the crown body (11), and a coupling guide portion (13) formed on an inner peripheral wall (121) of the abutment insertion recess (12) and having a scratch surface (131) formed on the surface of the inner peripheral wall (121), a silica layer (132) bonded to the scratch surface (131), a zirconia primer layer (133) coated onto the silica layer (132), and a resin (134) bonded to the zirconia primer layer (133).
