Description

SIMULATION MODEL FOR DENTAL EDUCATION
Technical Field
The invention is related to a simulation model that mimics real adult and pediatric dental anatomy and is used as a training material by dental students or individuals for practicing in the preclinical (pre-patient) stage.
In particular, this invention is related to a simulation model consisting of a fixation section imitating the bone structure of the upper and lower jaw, a palate section imitating the palate structure, and teeth, which has a realistic adult and pediatric mouth morphology, and in which teeth with caries, broken forms, teeth with different canal variations can be placed in accordance with the purpose of education.
Known Status of the Technique
Dental students simulate working in the human mouth by assembling the training materials they use during practice to the mouth of the phantom head. Today, models consisting of plastic upper and lower jaws that are named as phantom jaw and melamine teeth are the most common models used in dentistry education.
In the current technique, all of the teeth in the models consisting of plastic upper and lower jaws which are called phantom Jaw and melamine teeth are composed of the same material. In other words, there are no layers with different hardnesses that are found in real tooth structure. There are also no pulp chamber and canals in these teeth. Teeth on this jaw model do not conform to the anatomical form. Because teeth have to be screwed to be fixed to the jaws. For this reason, the roots of the teeth is produced missing. In current practices, teeth with canals are inserted into these jaws for endodontic training. However, these teeth are not suitable for real human tooth morphology. Only the upper half of the models conforms to human tooth morphology. On the other hand, the transparent lower part is a geometric shape with canals inside. This geometrical shape and the canals inside do not conform to the human morphology. Therefore, in the known state of the technique, there is a need for a simulation model with realistic adult and pediatric mouth morphology. In the literature review, an example of the known state of the technique can be given in the document numbered TR2020/17582. The document in question relates to a robotic system used in dental treatment training. In the mentioned invention, a robotic system that can automatically perform reflexes and movements on a modeled human head where the difficulties in the patient's mouth can be applied one-to-one in order to ensure that the application trainings given in dental treatment are close to reality, and that both head and jaw movements can be adjusted in the desired position by both students and the operator. However, in the aforementioned system, phantom jaws is used, which are fixed to the jaw bodies and have upper and lower dental palate groups on them.
As a result, the existence of the above problems and the inadequacy of existing solutions necessitated a development in the relevant technical field.
Purpose of the Invention
The present invention is related to a simulation model for dentistry, which eliminates the above-mentioned disadvantages and offers new advantages to the related technical field.
The main purpose of the invention is to present a simulation model with a realistic adult and pediatric mouth morphology consisting of a fixation section that mimics the upper and lower jaw bone structure, and a palate section and teeth that mimic the palate structure.
The purpose of the invention is to provide a simulation model in which teeth with caries, fractured forms and different canal variations can be placed in accordance with the purpose of the training.
Another purpose of the invention is to provide a simulation model that can be produced in transparent or opaque colors, has teeth with root canals and pulp chambers, and is also suitable for real adult and pediatric dentition.
A further purpose of the invention is to provide a simulation model in which all teeth can be removed and replaced with replacement teeth. Another purpose of the invention is to present a simulation model, that can be revised according to all the tooth models required in dentistry education, and in this way, students can practice by placing the transparent tooth in the jaw in endodontic training and practice by placing the tooth with caries in the jaw in restorative treatment training by using anatomically transparent teeth for endodontic education, opaque teeth for prosthesis education and opaque or transparent teeth with caries for restorative treatment training in the same jaw structure.
In order to fulfill all the above-mentioned purposes that may arise from the detailed description, the invention is a simulation model, which is used as a training material by students or individuals studying dentistry for the purpose of practice in the preclinical (pre-patient) stage and includes a fixation section on the outermost side of the upper jaw and lower jaw that mimics the adult and pediatric jaw bone structure, which mimics the real adult and pediatric dental anatomy and is related with, a palate section that is joined to the fixation section and mimics the upper and lower palate structure found in humans, a tooth that can be inserted and removed by making a tight fit in the palatal section and in a form suitable for adult and pediatric anatomy, a layer of enamel on the outside of the tooth that mimics the hardest layer, pulp that mimics the nerve structure of the tooth suitable for root canal treatment, the dentin layer of the tooth, which contains the pulp inside and the enamel layer outside, the pulp chamber, which is located in the crown of the tooth and forms the largest area of the pulp, the root canal where the pulp is located in the root area of the tooth.

Detailed Description of the Invention
In this detailed description, the preferred alternatives of the simulation model of the invention are described only for the purpose of a better understanding of the subject matter and without any limiting effect.
Figure 1 shows a general view of the simulation model of the invention. Accordingly, in its most basic form, the simulation model includes a fixation section (20) located on the outermost side of the upper jaw (10a) and lower jaw (10b) that mimics adult and pediatric dental anatomy, a palate section (20) that is connected to the fixation section (30) by making a tight fit and mimics the upper and lower palate structure in humans, a tooth (40) that can be inserted and removed in the palate section (30) and in a form suitable for adult and pediatric anatomy.
The upper jaw (10a) and lower jaw (10b), which constitute the main structure of the simulation model of the invention, mainly consist of a fixation section (20) that mimics the jawbone structure and a palate section (30) that mimics the upper and lower palate structure on which the upper and lower teeth (40) are placed in accordance with human anatomy.
The fixation section (20), located on the outermost side of the upper jaw (10a) and lower jaw (10b), mimics the jawbone structure found in adults and children. As can be seen in Figure 2, on the lower surface of the fixation section (20), there is at least one nut (21) that allows the upper jaw (10a) and lower jaw (10b) to be connected to the mouth of the phantom head during training, and a mutually recessed insertion cavity (22) that prevents the upper jaw (10a) and lower jaw (10b) from rotating in the mouth of the phantom head. The nut (21) is suitable for all phantom heads. The fixing section (20) has the rigidity and strength to hold the nut (21) in place and allow the upper jaw (10a) and lower jaw (10b) to be connected to the phantom head.
A palate section (30), which mimics the upper and lower palate structure of a humans, is connected to the fixing section (20). Since it is important that the upper jaw (10a) and the lower jaw (10b) are fixed and stable against the forces applied during operation, the relevant palate section (30) is fixed in the fixing section (20) with a tight fit. Accordingly, the palate section (30) has the necessary flexibility for the removal and insertion of the teeth (40) and is strong and rigid enough to be stable against the forces generated during the operation.
The teeth (40), which can be inserted and removed by tight fitting into the palate section (30), have a form suitable for adult and pediatric anatomy. The teeth (40) can be opaque or transparent. In order to ensure that the teeth (40) have a form suitable for adult and pediatric anatomy, they have an enamel layer (41) outside the teeth (40), which mimics the hardest layer, a pulp (42), which mimics the nerve structure in accordance with the root canal treatment of the teeth (40), a dentin layer (43) with the pulp (42) inside the tooth (40) and the enamel layer (41) outside, a pulp chamber (44) located in the crown of the tooth (40) and forming the largest area of the pulp (42), and a root canal (45) with the pulp (42) located in the root region of the tooth (40). Teeth (40) are provided with fixing protrusions (46) on both sides to securely attach them to the palatal section (30).
In an alternative embodiment of the invention, the pulp chamber (44) and root canal (45) may be completely empty.
In an alternative embodiment of the invention, all or at least one of the enamel layer (41), pulp (42), dentin layer (43), pulp chamber (44) and root canal (45) in the structure of teeth (40) may be present.
The simulation model of the invention simulates working in the human mouth by fixing to the mouth of the phantom head by means of a nut (21) in order to enable dentistry students to practice. In the present simulation model, all teeth (40) produced in various qualities for different dental disciplines can be inserted and removed from the upper jaw (10a) and lower jaw (10b), which are standardized in accordance with the purpose of the training. Thus, different courses can be trained on the same upper jaw (10a) and lower jaw (10b).
