Description
Technical Field
The invention belongs to the technical field of oral clinical medicine, and relates to a model for training tooth preparation of professionals in oral medicine experiment teaching.
Background
In oral clinical work, tooth defects, staining of teeth, dentition misalignment, saphenous fissures and the like caused by caries and the like are common clinical problems. In the process of solving the problems, specific grinding (namely tooth preparation) is needed to be carried out on tooth tissue, and then restoration is carried out to achieve the purpose of treatment. Hand manipulation skills determine the handling ability of the dentist, and experimental teaching is one of the most important components in the culture process of the dentist.
The traditional tooth preparation experiment teaching uses teeth (in vitro teeth) which are removed or pulled out by a user for training, and has the advantage that the hand feeling during grinding is consistent with clinical operation. However, the defects are very remarkable, including difficult sources, large randomness of tooth positions, damage or atypical tooth anatomy structure caused by tooth abrasion and caries, unrepeatable training and the like, and the evaluation mode can only be observed by naked eyes, so that the evaluation result is greatly influenced by subjective ideas of the evaluator. In order to make up the defects of the isolated teeth, a plurality of dental education industry equipment suppliers at home and abroad push out plastic teeth with different tooth positions for a trainer. The existing plastic teeth are mainly made of common plastics, and have the advantages of consistent tooth body shape with human tooth body shape, clear and typical anatomical structure, repeatable exercise of the same tooth position, reasonable price and the like, and have the defects that the grinding target is not clear enough during training, the evaluation mode still can only be observed by naked eyes, and the evaluation result is difficult to be objective, so that the training person is not led to gradually improve the operation accuracy. In addition, there is a certain difference in hardness from the actual tooth hardness, resulting in a certain difference in hand feel.
In order to make the evaluation of dental preparation more objective, digital oral teaching evaluation systems are developed in recent years on the market successively, which have the advantages that the operation of the operator is objectively evaluated in the process by loading a positioner and an external probe on a dental turbine; or the external scanner is used for scanning the tooth model after grinding in vitro so as to realize objective result evaluation. However, the method has certain limitations, such as high equipment price (about 75 ten thousand yuan people and one machine is needed for training) for process evaluation, great increase of weight of the rear part of the turbine caused by loading of the positioner, obvious influence on operation of a trainee, easy interruption of a probe signal due to shielding by an object, large occupied area and the like; the result evaluation device is required to take out the dental model and put the dental model into a scanner to influence the smoothness of evaluation when working, and a trainee does not know how to improve the evaluation after the evaluation is finished, so that the evaluation process is relatively complex to operate.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a color partition type tooth preparation training model so as to ensure that a trainee can clearly and objectively feed back training results in real time and guide the trainee to gradually improve the operation accuracy.
The color partition type tooth preparation training model consists of a tooth preparation training model corresponding to each tooth position, wherein the tooth preparation training model corresponding to each tooth position consists of a fixed section and a preparation training section, the preparation training section is an integrated structure formed by combining target areas with the same materials and different colors, error allowed areas and forbidden areas, the target areas are areas which need to be ground during training, the error allowed areas are areas which can be ground during training, the forbidden areas are areas which cannot be ground during training, and the error allowed areas are positioned between the target areas and the forbidden areas and encircle the target areas.
The thickness (i.e., the error range) of the error allowable area of the color partition type dental preparation training model can be set according to the training degree or the investigation requirement of a trainee, and is generally 0.05-0.8 mm. In the error range, tooth preparation training models of different thickness error allowable areas can be designed and prepared, so that the requirements of trainees of different layers are met.
The color partition type tooth preparation training model comprises 20 deciduous tooth preparation training models or 32 permanent tooth preparation training models of a person.
The color partition type tooth preparation training model is made of engineering plastics so that the hardness of the model is more similar to that of real teeth, and the clinical operation of a trainee after training is not influenced by the difference between training and clinical hand feeling; the engineering plastic may be polyoxymethylene (abbreviated as POM), ABS plastic (acrylonitrile-butadiene-styrene plastic), or the like.
The preparation method of the color partition type tooth preparation training model is injection molding or 3D printing.
The color partition type tooth preparation training model has the following beneficial effects:
1. because the preparation training section of the tooth preparation training model comprises the target areas with different colors, the error permission area and the forbidden area, the tooth preparation training model is used for training, a trainee can clearly grind the target, and can objectively feed back the training result in real time, so that errors caused by subjective factors of a teacher or an evaluator are avoided, and training standards are unified.
2. By using the color partition type tooth preparation training model for training, a trainee can independently practice and evaluate, and correct according to tooth color distribution in time, and the operation accuracy is gradually improved, so that not only can the teachers and the materials be greatly saved, but also the training amount in unit time can be obviously improved, and the experimental teaching process becomes more efficient and simpler.
3. The training result can be fed back objectively in real time by using the tooth preparation training model, so that the training result does not need to be evaluated by a digital oral teaching evaluation system, the equipment purchase cost can be saved, the evaluation mode of the training result is simpler and smoother, and a trainee knows how to improve specifically.
4. Because the manufacturing material of the tooth preparation training model is engineering plastic, compared with the existing plastic tooth preparation training model, the hardness of the tooth preparation training model is closer to that of real teeth, and the operation of a trainee in clinic after training is not influenced by the difference between the hand feeling of training and clinic.
5. Because the color partition type tooth preparation training model can be prepared by 3D printing, the training content can be designed in a personalized way and combined with clinical case data, so that the training is closer to the clinical actual situation, and the training effect is further improved.
