Dental Image Monitoring via 3D Tooth Projection Alignment

The patent replaces the mechanical impression system with an optical imaging system. Instead of using viscous material that requires mechanical removal and handling, the system uses digital cameras to capture multiple two-dimensional images of the patient's oral cavity, which are then computationally reconstructed into three-dimensional models. This eliminates the time-consuming mechanical impression process while maintaining accuracy.

The patent creates digital copies of the patient's teeth and oral cavity through optical imaging rather than physical copies through mechanical impressions. Multiple two-dimensional photographs are taken from different angles and computationally assembled to create accurate three-dimensional digital models, avoiding the need for physical impression materials that can be damaged or altered.

The system replaces the mechanical removal process with non-contact optical imaging. Digital cameras capture images of the patient's teeth without requiring physical contact or material removal, completely eliminating the risk of damaging or altering the impression material during the removal process.

Instead of creating physical impressions that can be damaged, the system creates digital copies through optical imaging. The three-dimensional model is generated computationally from multiple two-dimensional photographs, ensuring the data integrity is maintained without physical handling that could cause alteration or damage.

The patent replaces the uncomfortable mechanical impression process with a painless optical imaging process. Instead of having the patient bite into viscous material, they simply sit in a chair while digital cameras capture photographs of their teeth from multiple angles, significantly improving patient comfort and ease of operation.

The system uses optical copying through digital photography instead of mechanical copying through physical impressions. This eliminates the unpleasant sensation of biting into viscous material while still achieving accurate three-dimensional digital models of the patient's teeth.

The patent implements a feedback mechanism that compares current two-dimensional photographs of the patient's teeth with the original three-dimensional model and the treatment plan. The system automatically generates reports indicating whether the treatment is proceeding as expected, providing real-time feedback to dental practitioners without requiring complex manual analysis.

The system uses digital copies from multiple sources (original three-dimensional model, current two-dimensional photographs) to create a comprehensive monitoring system. By comparing these digital copies automatically, the system provides treatment progress assessment without requiring complex physical monitoring procedures or additional expensive equipment.
