Description

A wireless intelligent occlusal device that monitors the "occlusal function of the oromandibular system"

Technical field

The utility model relates to the field of dental bite plates, and in particular to a wireless intelligent bite device that monitors "the bite function of the oral and jaw system".

Background technique

Abnormal occlusion during mandibular movement is an important pathogenic factor for many diseases of the stomatognathic system. Bruxism, clenching, periodontal occlusal trauma, restorative design, loading of dental implant occlusal force, occlusal reconstruction, changes in occlusal relationship during orthodontic process, post-traumatic adjustment, temporomandibular joint disorder, occlusal reconstruction, early contact, □ Trauma and other common occlusal problems in oral clinics. Articulation paper has always been used clinically to check for abnormal occlusion, but this method is not intuitive and the accuracy of the results is low. It lacks efficient and intuitive guidance for the diagnosis and treatment of dental clinicians. However, bad occlusal habits such as grinding teeth and clenching teeth at night are difficult to monitor long-term in clinic. Therefore, it can simultaneously meet the monitoring and guidance of clinical mandibular movement abnormalities, as well as the patient's long-term self-wearing of smart bite plates, and wireless transmission of data to smart terminals to meet the doctor's long-term monitoring needs. A method of monitoring "orofacial system occlusion function" Wireless intelligent bite splints are particularly necessary.

There are many methods and types of equipment for accurately measuring bite force in the world, such as Dentoforce2 (2nd generation bite force, Sweden), T-Scan III (T-type bite analyzer III, United States), Flexiforce (flexible sensor, United States), DentalPrescale 2 (Dental Prescale 2nd Generation, Japan), GM10 (Hydraulic Scale GM10, Japan), FSR 151 (Force SensingResistor 151, Force Sensitive Sensor, United States), etc. However, after repeated use, there is a decrease in sensitivity and mechanical response. Narrowing of the range, etc., thus affecting the accuracy of the results. At the same time, the equipment cannot meet clinical needs in terms of miniaturization, portability, price, and wireless transmission of data. For example, the current T-Scan (T-Type Occlusion Analyzer, United States) occlusion analyzer system is a representative product among the sensors for dynamic monitoring of bite force in the world. T-Scan III (T-Type Occlusion Analyzer III, United States) occlusion analyzer system The force-sensitive sensor chip is only 85 μm thick and can accurately monitor and analyze the contact area, size, and distribution position of the bite force, and compare the analysis results of the front, rear, left, and right areas. However, the entire system is expensive and can only be used clinically at the chairside. For testing, patients cannot use it at home. Its domestic application is limited to individual universities and scientific research units, and it is rarely used in clinical practice.

Domestic researchers have also developed numerous bite plates. For example, utility model patent CN206714837U discloses a multifunctional bite plate and an intraoral vibrator with the bite plate. The bite plate includes a frame, and the frame has There are fixed holes corresponding to each tooth position, and a detachable tooth position buckle can be provided in each fixed hole position. However, since everyone's teeth are arranged differently, this bite plate cannot be suitable for all people. Patient; Utility model patent CN217853457U discloses an occlusal plate and an occlusal force monitoring system. The occlusal plate still uses wired transmission, which is inconvenient to use.

In view of the technical problems existing in this field, the utility model provides a flexible device, which has excellent performance in thickness, sensitivity, accuracy, repeatability, mechanical response range, response time, multi-axial force monitoring, sensor principle, sensor form, and wireless The bite force sensor analysis and recording system with good performance and conditions in terms of transmission, terminal analysis and price will lay a solid foundation for the development of subsequent diagnostic sensors and provide a more accurate and reliable intuitive basis for guiding clinical diagnosis and treatment.
