METHOD FOR PLANNING DENTAL IMPLANTATION USING IMPRESSION TRAY WITH RADIOPAQUE MARKS Russian patent published in 2024 - IPC A61B6/51 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical and orthopaedic dentistry, and is intended for use in planning dental implantation. Jaw is imprinted with a dental silicone mass. Computed tomography is performed. Digital model of the jaw is created based on the obtained impression. Jaw impression is made with an impression tray made of non-radiopaque polymer materials. On the external surface of the tray, three marks are created in the form of hollow cylinders with diameter of 4 mm – one in the area of central incisors and one in the area of molars on each side of the jaw. Cylinders are filled with dental radiopaque material. Using this tray, an impression is taken, and the tray is not removed from the oral cavity, a computed tomography is performed. Then the tray is removed from the oral cavity and a digital model of the impression tray with an impression of the jaw is obtained, a digital model of the jaw is created from the obtained impression, impression tray and digital impression, located in the same coordinate system, are compared, by radiopaque marks fixed on the tray, with the obtained computer tomogram and the surgical template is made by determining the position of the implants according to the anatomical structure of the jaw.

EFFECT: by using the impression tray with radiopaque marks applied on its outer surface, the method enables planning the dental implantation operation, eliminating the possibility of the template shift during the X-ray examination.
