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
