However, there are several disadvantages in using the conventional tooth model fixed rack as described above.
First, a dental model made of gypsum has a different contraction ratio depending on the surrounding conditions when it is solidified and contracted, causing a slight error in occlusion and affecting the precision of the denture. Since errors occur in the processing of the fixed frame of each tooth model, the other tooth model cannot be diverted to the fixed frame of the other tooth model, so wait until the denture is completed to some extent. The next denture cannot be made unless it is empty. Also, when the tooth model is completed, the state of occlusion with the patient is confirmed by delivering the fixed frame to the dentist.In other words, by sending the model together with the fixed frame, the fixed frame can be immediately transferred to the next production. First, there is a loss of time.
Therefore, in view of the above-mentioned drawbacks, the present invention provides a structure for fixing a tooth model of the present invention in order to improve the occlusal situation when manufacturing the tooth model and to further improve the practicality.
