Description

Technological sector of invention [001] The present invention belongs to the education sector, more specifically in dentistry, and refers to a dental training model that replaces traditional simulators, offering a portable and realistic learning solution. It accurately simulates the complete oral cavity, including structures absent in other products, such as the vestibule, silicone face, palate, tongue, and tonsils, providing a more faithful experience to clinical practice. Its design allows the use of interchangeable refills, adapting to up to 8 different disciplines with the same equipment, which reduces costs for students and institutions, as well as minimizing environmental impacts. In addition, it can be equipped with sensors that provide real-time feedback on procedures such as anesthesia, assisting in the improvement of technique. The attachment system allows the replacement of gums and teeth, increasing the durability of the equipment and offering greater flexibility in training. The product is primarily intended for undergraduate and university students of dentistry, serving as a tool for developing neuromotor skills in the study and practice of dental surgeons, enabling students to perform their professional duties more efficiently and accurately. State of the art [002] Traditional teaching simulators used in dental institutions, such as those produced by brands like Orais Manequins, Pronew, MOM (Manequins Odontológicos de Marília), and Dent Art, have a similar structure, differing only in aesthetic aspects and methods of fixing the dental mannequin within the simulator. However, these simulators do not offer a complete reproduction of the oral cavity, being limited to the gums, teeth, and lips, which compromises the quality of training. This limitation creates an artificially broad and simplified field of work, making learning less realistic and hindering the student's adaptation to clinical care with real patients. [003] Furthermore, traditional simulators are installed exclusively in university laboratories, restricting students' practice to the time available in these environments, which significantly reduces training time. The lack of portability prevents students from practicing outside the laboratory, limiting their technical development. This factor represents a significant disadvantage, as dentistry requires motor refinement, precision, and repetition of techniques, something that would be enhanced with equipment that allows practice in different locations. [004] The greatest challenge is to provide a solution that simulates all the anatomical structures of the human mouth, such as the mandibular rami, the mandibular pterygium fold, the retromolar trigone, the tonsils, the tongue, the hard and soft palate, the alveolar ridge, the buccal mucosa, the vestibular fornix, the lips and cheeks, as well as the internal bone topography. These structures are essential for performing various dental techniques, making a more realistic and complete simulator indispensable. [005] Furthermore, a portable model would allow students to train anywhere, including at home, extending practice time and contributing to the training of professionals who are better prepared and qualified for clinical practice. By offering a simulator that faithfully reproduces the oral cavity and provides freedom of training, it would be possible to optimize learning, ensure better preparation for patient care, and increase the efficiency of dental education. New Invention Details [006] The dental training device offers significant advantages over traditional simulators and mannequins. Its portability allows students to practice anywhere, including their own homes, extending training time and improving the quality of training. At the same time, it can be integrated with fixed university simulators to meet the needs of institutions that prefer to maintain their traditional laboratories, making it versatile for both portable and fixed use. The device accurately simulates the complete oral cavity, including anatomical details such as the mandibular rami, tongue, tonsils, hard and soft palate, vestibular fornix, buccal mucosa, lips, and cheeks. This anatomical richness allows for the training of techniques that were previously impossible, making learning more realistic and comprehensive. [007] Another innovation is the interchangeable refill system, which adapts the device to up to eight different disciplines, such as anesthesiology, periodontics, restorative dentistry, complete dentures, endodontics, among others. The same refill can be reused for different disciplines simply by changing components such as teeth and gums, which reduces costs and generates less environmental impact. For example, pink gums and healthy teeth are used for restorative dentistry, while transparent gums and teeth with paint simulating dental calculus are used in periodontics. For complete dentures, a completely edentulous refill is used. [008] The device a
