The invention discloses a tongue blocking device for mouth rehabilitation based on the mouth rehabilitation department, and relates to the technical field of mouth rehabilitation, the tongue blocking device comprises a bearing plate, a connecting rod is welded to the outer side face of the bearing plate, an adjusting mechanism is arranged at the end, away from the bearing plate, of the connecting rod, and the adjusting mechanism is used for adjusting the extrusion force on the mouth. By arranging the adjusting mechanism, after the bearing plate is placed on the jaw of a patient, the effect of positioning the device in the oral cavity of the patient can be achieved by starting the adjusting mechanism, a circulation mechanism is arranged at the end, away from the bearing plate, of the connecting rod and used for changing the circulation mode of liquid, and the circulation mechanism comprises a middle pipe. The middle pipe is welded to the end, away from the bearing plate, of the connecting rod, and communicating pipes symmetrically penetrate through the outer side face of the middle pipe, so that the tongue of a patient is blocked during oral rehabilitation.

This invention discloses a virtual fitting system for dental prostheses based on 3D scanning, belonging to the field of digital dental prosthodontics. It includes a data acquisition module, a trajectory processing module, a model construction module, a fitting simulation module, and an anomaly optimization module. Through 3D scanning and automated point cloud processing, it can quickly acquire high-precision 3D models of the maxillary and mandibular dentition, providing reliable data support for prosthodontic design. Optical motion capture fully reproduces the patient's physiological mandibular movements, overcoming the limitations of existing systems that can only perform static simulations, making occlusal detection more clinically accurate. A unified reference coordinate system is established to achieve precise model registration, controlling prosthodontic positioning errors within 0.01mm, significantly improving fit. It can automatically identify premature contacts and occlusal interferences and perform intelligent optimization of the occlusal surface, replacing repeated manual adjustments, effectively shortening the treatment cycle, improving prosthodontic accuracy and wearing comfort, and enhancing the overall treatment experience.
