Abstract
Abstract An artificial tooth assembly has an artificial tooth crown and a denture base. The denture base comprises a cylinder seat, a plurality of plates, a threaded stud, a post and a hexagonal rod. The cylinder seat has a threaded hole, a plurality of longitudinal slots, and a plurality of transverse slots. Each longitudinal slot communicates with each corresponding transverse slot. An oblong hole is formed on each plate. A hexagonal recess hole is formed on the threaded stud. The post has a threaded lower portion and a mount. A hexagonal through hole is formed on the post. The plates are inserted in the corresponding transverse slots. A plurality of bolts are inserted in the corresponding longitudinal slots and the corresponding oblong holes to position the plates. The threaded stud is inserted in the cylinder seat. The threaded lower portion of the post is inserted in the cylinder seat. The hexagonal rod passes through the hexagonal through hole and the hexagonal recess hole. The artificial tooth crown is disposed on the post.
