METHOD FOR PLANNING ORTHOGNATIC SURGICAL OPERATION Russian patent published in 2015 - IPC A61B6/03 A61C7/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to dental surgery, and is applicable for oral surgeries. A cone-beam computerised oral tomography is performed successively. A skeletal and soft tissue cephalometric points are marked on the created 3D-computer model of skull. A combination thereof enables performing the 3D-cephalometric analysis of bone and soft tissues. A list of cephalometric points includes Basion (Ba) and a number of other standard points. Three skeletal points in the right part of the skull are additionally included: Tuber (Tub) R is a point within a joint of a right maxillary tuberosity and a pterygoid process at 1 mm above a palatal root of the last (if the molar is absent, the most posterior point within a maxillary sinus floor is taken); Alare (Al) R is the most lateral point within a nasal aperture on the right from the point ANS; Palatinum (Pal) R is a point within an anterior wall of a right aperture of greater palatine canal on the inferior surface of a horizontal plate of palatine bone. Three skeletal points in the left portion of the skull similar to those stated above are also included into the list of cephalometric points.

EFFECT: method enables simplifying and reducing the labour input of planning the orthognatic surgical operation, increasing the quality of the operation.
