Dental crown occlusal force measuring device and method
By arranging a multi-array pressure sensing module and a machine learning model on the inner side of the crown, the accuracy and stability issues of occlusal force monitoring in existing technologies have been solved. Dynamic monitoring of implant crowns and ordinary full crowns has been achieved, reducing the risk of sensor dislodgement and trauma, and adapting to wear and changes in occlusal habits during long-term use.

AI Technical Summary
Existing technologies struggle to achieve accurate and long-term occlusal force monitoring of implant crowns and ordinary full crowns without interfering with normal occlusal function. Furthermore, sensors are prone to detachment, cause significant trauma, have low measurement accuracy, poor mechanical compatibility, and cannot adapt to wear and changes in occlusal habits during long-term use.
A multi-array pressure sensing module is arranged on the inner side of the crown, and data analysis is performed in combination with a machine learning model. The built-in sensor avoids stress concentration areas on the inner side of the crown. Multi-layer biocompatible encapsulation and temperature drift compensation are used to achieve dynamic monitoring and adaptive correction. The sensor is detachable and replaceable, and an abnormal early warning module is integrated.
It enables in-situ dynamic monitoring of bite force across different scenarios, improves measurement accuracy and stability, reduces the risk of sensor detachment and damage, adapts to wear and changes in bite habits during long-term use, and ensures mechanical performance and aesthetic requirements.
