"System And Method Of Forming A Custom Bleaching Tray With Trench And Material Reservoirs" in Patent Application Approval Process (USPTO 20240315821).

A patent application has been filed for a system and method of forming a custom bleaching tray for teeth whitening. The invention aims to provide a solution that avoids contact between the whitening material and the gums, preventing irritation and color change. The device includes a trench to prevent leakage of the bleaching material onto the gums and a reservoir to hold the material on the surface of the teeth. The method involves generating a digital model of the patient's mouth based on teeth scan data and 3D-printing a custom bleaching tray that includes the trench and reservoir. The system includes a computing device, software module, and 3D printer. [Extracted from the article]
