TOOTH MODEL FOR DENTAL TRAINING AND DENTAL TRAINING APPARATUS HAVING THE TOOTH MODEL IMPLANTED THEREIN

摘要

It is intended to provide a tooth model for dental training and a dental training apparatus showing no eccentricity of tooth axis even after repeatedly taking out. In the tooth root side of a tooth model for dental training having a tooth crown 1 and a tooth root (2), a tooth model fixation member (3) which is made of a flexible synthetic material and has a column shape having a tooth axis (8) as the central axis is formed. At the bottom side, this fixation member has an enlarged part (7) enlarged outward around the tooth axis. This enlarged part is divided into smaller parts by dividing faces passing through the tooth axis and each division can flex toward the tooth axis side. In a dental training apparatus, the above-described tooth model is implanted into a fixation table (4) having an implantation hole (5) capable of containing at least a part of the tooth root and the tooth model fixation member therein. Upon extraction, each division of the enlarged part shifts into the tooth axis side and thus a locking member (6) provided in the implantation hole and each division of the enlarged part is unlocked.
