Precision Reimagined: Engineering a Better Experience for the MouthWatch Plus+ HD
MouthWatch set out to enhance the performance, manufacturability, and usability of their Plus+ HD intraoral camera. They needed a new housing design that would lower production costs, improve durability, and maintain exceptional image quality—while also addressing assembly challenges, heat management, and optical clarity.
Suntra MedTech Solutions led a comprehensive redesign of the camera’s outer housing, transitioning to ultrasonic welding for faster, stronger, and more cost-effective assembly. We applied poka-yoke principles to eliminate assembly errors and selected new materials optimized for bonding and user interaction. Internally, our team refined the lens mount to reduce labor and prevent image-degrading debris, optimized gasket materials for tactile button feedback, and collaborated with the original lighting designer to eliminate light leaks and sharpen imaging fidelity. On the electrical side, we introduced a simple but effective thermal solution—a 10¢ component—to address internal hot spots and improve user comfort.
The re-engineered MouthWatch Plus+ HD delivered on all fronts: improved manufacturability, better thermal performance, and higher image quality—all while reducing cost and assembly time. The result is a camera that looks sharper, feels better, and performs more reliably—giving clinicians the clarity and confidence they need at the point of care.
