Description

Technical Field

[0001] The utility model belongs to the technical field of oral teaching, and specifically relates to a dental pulp angiogenesis experimental teaching model. Background Art

[0002] Dental pulp revascularization is a new clinical technology for the treatment of periapical periodontitis in young permanent teeth. Its efficacy has been widely recognized internationally. With the increasing clinical application of dental pulp revascularization, the importance of model tests before operation continues to increase. At present, in addition to theoretical training, there are only virtual simulation experiments in the training of experimental operations, which cannot provide sufficient preparation for actual clinical operations. Therefore, the design of a dental pulp revascularization model is of great significance in clinical teaching.

[0003] Therefore, providing an experimental teaching model for dental pulp revascularization to serve as a bridge between preclinical skill training and clinical operation and to enhance students' job competency has become an urgent issue to be solved by technical personnel in this field. Utility Model Content

[0004] The utility model aims to provide a dental pulp angiogenesis experimental teaching model to solve the problem that there is no dental pulp angiogenesis model for students to practice in the prior art.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The dental pulp angiogenesis experimental teaching model comprises a simulated dentition, a simulated blood sac arranged on the simulated dentition and a transparent root canal tooth model, an infusion device is connected between the simulated blood sac and the transparent root canal tooth model, and a simulated root canal is arranged in the transparent root canal tooth model.

[0007] In some embodiments of the utility model, simulated periapical tissue is provided in the simulated dentition, the apex of the transparent root canal tooth model is connected to the simulated periapical tissue, and the infusion device passes through the simulated periapical tissue and extends into the simulated root canal of the transparent root canal tooth model.

[0008] In some embodiments of the utility model, the infusion device includes a venous blood collection needle A inserted into a transparent root canal tooth model, a venous blood collection needle B inserted into a simulated blood bag, and a catheter connected between venous blood collection needle A and venous blood collection needle B.

[0009] In some embodiments of the present invention, a screw clamp for tightening or loosening the simulated blood sac is provided on the simulated blood sac.

[0010] Some embodiments of the present invention further include a base, and the simulated dentition is arranged on the base.

[0011] In some embodiments of the present invention, the simulated dentition and the base are an integrated structure.

[0012] In some embodiments of the utility model, at least two through holes and a groove for embedding a catheter are provided on the base, and the venous blood collection needle A penetrates into the transparent root canal tooth model from the top of the base through one through hole, and the venous blood collection needle B penetrates into the simulated blood bag from the top of the base through another through hole.

[0013] In some implementation schemes of the utility model, an embedding hole is provided on the base.

[0014] In some implementation schemes of the utility model, a plug-in slot adapted to the transparent root canal tooth model is provided on the simulated dentition, and the transparent root canal tooth model is movably plugged into the plug-in slot.

[0015] In some implementation schemes of the utility model, a receiving groove adapted to the simulated blood sac is provided on the simulated dentition, and the simulated blood sac is movably received in the receiving groove.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model has a scientific design and a simple structure, and fills the experimental operation gap in the prior art. At this stage, the study of dental pulp angiogenesis can only be carried out through textbook theoretical study, observing the clinical operation of the learning instructor, and using computers for virtual experiments, but it is impossible for students to practice the operation by themselves, and it is impossible to gain more personal experience and feelings in the personal operation, resulting in the overall learning being imperfect. This dental pulp angiogenesis model can be used in experimental teaching, case analysis and other occasions. There is sufficient objective demand in oral medicine education, and medical schools have a demand for corresponding teaching models. The market capacity is sufficient and the market potential is great. With the trend of dental pulp angiogenesis being used more and more, the emergence of corresponding teaching and training models is necessary.

[0018] The utility model is scientific and environmentally friendly. The utility model has the advantages of being scientific, convenient, intuitive, and repeatable. It is designed strictly based on theories, clinical operations, virtual experiments, and other materials, and uses commonly available materials to form its structure. It allows students to use clinical operation instruments to simulate clinical actual operations on the basis of theoretical learning, especially in the steps of stimulating periapical tissue bleeding and forming blood clots. By consulting literature and pre-experimental operations, we strive to select materials for each part of the model that are close to the structural characteristics of each layer of the ex vivo tooth, so that the experience during operation is similar to that of operating in the patient's mouth. At the same time, in terms of material selection, we adhere to the concepts of green, environmental protection, and health to avoid unnecessary negative impacts on the environment and the health of the operator. The model can be reused many times, which can effectively reduce material waste and reduce the burden on resources and the environment. In addition, the steps of the model operation are concise and accurate without being complicated and redundant, which makes the students' experience more intuitive during the experiment, so as to obtain a deep and clear impression.

[0019] The utility model has low cost and the material selection takes into account biological safety. The venous blood collection needle, simulated blood bag, transparent root canal tooth model and dentition model used in the experiment have low cost. The transparent root canal tooth model and simulated blood bag can be replaced. After a student completes the operation, only some parts need to be replaced and the next student can operate, which is low cost.

[0020] The utility model is easy to assemble and provides students with a real experience of clinical treatment operations. The utility model embeds the infusion device in the embedding groove, and the appearance of the dentition model is neat and tidy without redundant accessories, so that the model is compatible with the laboratory Kavo simulation head model, and students can operate on the simulation head model (i.e., the intraoral environment), which is close to the clinic. One end of the medical venous blood collection needle is inserted into the apical foramen of a single transparent root canal tooth model and connected with its root canal. When in use, a simulated blood sac of the same size as the tooth is inserted into the adjacent tooth position, and the blood sac is pierced with the needle that passes through the adjacent tooth position, and then the blood sac is squeezed with a screw clamp and the pressure is maintained, so that the simulated blood inside the blood sac slowly flows to the root apex of the affected tooth through the catheter and further fills the root canal of the affected tooth and maintains a height below the cementoenamel junction, so as to simulate the step of blood overflowing to the cementoenamel junction after bleeding from the apical tissue in clinical operations. In addition, the blood enters the root canal of the affected tooth from the apical tissue, which can truly restore the clinical situation. Students do not need to inject additional red liquid from the crown of the root canal, reducing unnecessary non-clinical operations.

[0021] The use of the utility model can help to form a closed-loop teaching model for the teaching of dental pulp revascularization. On the basis of existing theoretical teaching and virtual simulation training, experimental hands-on operation and post-class feedback evaluation are added to help students smoothly transition to clinical practice, forming a closed-loop teaching model that combines virtual and real, and mixes online and offline.
