Dental Stress Visualization Using Biopotential Sensing and AR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting patient pain or discomfort during dental treatments are inefficient, as manual gestures may not be noticed by clinicians, leading to a need for automated and real-time visualization of stress levels to improve patient experience.
Innovation Solution
A system utilizing biopotential sensors to retrieve patient information, analyze it, and overlay stress data in real-time on a predetermined site through augmented reality, allowing clinicians to adjust treatment accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual gestures are used to indicate pain, then the patient can communicate discomfort, but the clinician may not notice the gestures in time and the process is inefficient
Solution Approach 1:
The patent replaces the manual mechanical gesture system with an automated biopotential sensing system. Electrophysiological sensors detect electrical signals from the patient's body (such as heart rate variability, skin conductance) that automatically indicate stress or pain levels, eliminating the need for manual gestures and ensuring the clinician receives real-time information without distraction.
Solution Approach 2:
The system implements continuous feedback by monitoring biopotential signals and providing real-time information to the clinician about the patient's stress state. This closed-loop feedback mechanism allows the clinician to adjust treatment immediately based on objective physiological data, improving both information retention and treatment efficiency.
2Reliability
If the clinician focuses on treatment, then treatment quality improves, but the clinician cannot monitor patient stress signals that are out of view
Solution Approach 1:
The patent introduces an intermediary automated monitoring system that acts as a bridge between the patient and clinician. The biopotential sensors and processing system serve as a mediator that continuously observes the patient's physiological state and communicates relevant information to the clinician, allowing the clinician to maintain focus on treatment while still receiving stress information through the intermediary system.
3Measurement precision
If automated biopotential sensing is implemented, then real-time stress visualization is achieved, but device complexity increases
Solution Approach 1:
The patent employs biopotential sensors that can detect multiple physiological parameters simultaneously (heart rate, skin conductance, muscle activity) using a single integrated system. This multi-functionality approach achieves precise stress measurement without proportionally increasing system complexity, as one sensor array serves multiple detection purposes.

AI summary
A system for visualizing patient stress or discomfort during dental treatment. By visualizing a patients changing stress conditions during treatment, a clinician may react accordingly such as by stopping a treatment activity, slowing a treatment activity, refreshing anesthesia, etc. in order to improve the patients experience.
