Problems solved by technology

At present, most of the edentulous maxillary models on the market simply imitate the surface morphology of the edentulous jaw in the mouth, which cannot directly simulate the real structural state of the maxillary tissues; at the same time, most of the existing models are made of hard plastic materials, which cannot be effectively Reflects the hardness of each tissue, and cannot simulate the yield of soft tissue
Therefore, in the process of teaching or communicating with doctors and patients, the other party cannot get a better intuitive experience, and the explanation effect is poor
[0003] At the same time, the existing maxillary edentulous models cannot be directly applied to the in vitro study of dentition soft tissues due to their material and fineness limitations.

Abstract

The invention discloses a high-simulation edentulous jaw soft and hard maxillary tissue in-vitro model. The high-simulation edentulous jaw soft and hard maxillary tissue in-vitro model comprises a chewing mucous membrane simulation layer, a palate gland simulation layer and a maxillary hard tissue simulation layer. The chewing mucosa membrane simulation layer, the palate gland simulation layer andthe maxillary hard tissue simulation layer are movably connected in sequence from top to bottom. The in-vitro model disclosed by the invention is highly similar to the form of the soft and hard tissues of the maxillary toothless part, and the hardness of each soft tissue on the model is also similar to the hardness of the soft tissues of the maxillary part. When the structure of the edentulous jaw toothless soft and hard tissue is explained for a patient and a student, the patient or the student can obtain the most intuitive feeling in a direct touch mode. Meanwhile, the hardness of the softtissue is the same as that of the physiological structure, so that the soft tissue can be used as a model for simulation research of soft tissue yielding in in-vitro research, has important scientificresearch value and can be widely applied to the field of medical models.

Description

technical field [0001] The invention relates to the field of medical models, in particular to a high-simulation in vitro model of soft and hard tissues of the maxillary edentulous jaw and a manufacturing method thereof. Background technique [0002] The maxillary edentulous jaw model is mainly used to explain anatomical landmarks in medical teaching; or explain the structure of maxillary tissue to patients in the process of doctor-patient communication, so as to improve patients' understanding of oral structure. At present, most of the edentulous maxillary models on the market simply imitate the surface morphology of the edentulous jaw in the mouth, which cannot directly simulate the real structural state of the maxillary tissues; at the same time, most of the existing models are made of hard plastic materials, which cannot be effectively Reflecting the hardness of each tissue, it is also impossible to simulate the soft tissue yield. Therefore, in the process of teaching or...
