Digital dental scanning technology for Glissade Dental
Customer
Glissade Dental manufactures the Intra-Oral Dental Scanner (IODS), a low-cost, high-precision 3D oral scanner. The company aims to disrupt the market for digital dental scanners by offering its low-cost dental imaging device. The device uses patented Emission Re-absorption Laser-Induced Fluorescence (ERLIF) technology created by MIT Professor Douglas Hart. The device has completed its functional alpha prototype and has entered the preliminary clinical testing phase.
Name: Glissade Dental
Industry: Healthcare
Location: Boston, MA, USA
Challenges
- Glissade dental scanner was producing poor quality scanned data with lots of noise and holes
- Scanned data was not directly usable for dental treatment planning without further processing
- It used to take lots of time and effort to clean up the data and prepare for treatment planning
Solution
- Developed a state-of-the-art algorithm to create a high-quality surface mesh and fill holes from scanned data automatically
- Software was implemented using C++ and delivered as a library to be integrated with their application
- Helped integrate the library with a desktop application built using C++, Qt, OpenCV, and OpenGL
Results
- Fully automated process to reconstruct 3D model from scanned data with noise and gaps/holes due to missing data
- Reduced the time it takes to clean up the scanned data from hours to minutes
- The result is a high-quality surface mesh that can be used for treatment planning and 3D printing
