METHOD OF DETERMINING DEVIATIONS OF INSTALLED DENTAL IMPLANT FROM PLANNED POSITION Russian patent published in 2025 - IPC A61C8/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical dentistry and can be used for analysis of precision planning and performance of dental implantation. At the planning stage, a virtual model of a dental implant connected to a virtual model of a scan marker of the same implantation system as the dental implant is positioned in place of the missing tooth in the computer program. A navigation template of the dental implant to be placed is virtually modelled, which is then made by 3D printing. A dental implant is placed according to a template made by 3D printing, then a scan marker is fixed in the dental implant. After the dental implant is installed during the operation, during the computed tomography process, the dental arches are scanned with the installed scan marker, thus obtaining a virtual model of the installed dental implant with the scan marker. A virtual model of the dental implant with a scan marker obtained at the planning stage in the preoperative period is compared with a virtual model of the installed dental implant with a scan marker obtained during the operation after installation of the dental implant. Measurements are virtually carried out by markings. On the basis of the obtained data, deviations of the implant parts are determined on its virtual models obtained at the planning stage in the preoperative period and during the operation after the implant installation.

EFFECT: enabling assessment of deviation of the position of the actually installed implant from the position of its virtual model, obtained during the operation planning, directly during the operation.
