METHOD FOR DETERMINING TYPE OF PALATAL VAULT FOR TACTICS OF ORTHODONTIC TREATMENT DURING OCCLUSION OF PERMANENT TEETH Russian patent published in 2022 - IPC A61C19/04 A61B5/103 A61B6/02 A61B8/13 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to dentistry, and can be used to determine the shape of the palatine fornix by individual morphometric parameters of dentoalveolar arches. Palatal arch width is measured between the points located in the interdental spaces between the second premolars and the first molars, followed by measuring the height and width of the palatal arch on plaster models of jaws or on frontal sections of cone-beam computed tomograms (CBCT). Palatinal index (PI) is determined. Width of the palatine vault is measured between points located in the interdental spaces between the second premolars and the first molars (K2). Then the distance of the height of the palatine vault (K1) is measured, which corresponds to the length of the perpendicular from the line K2 to the deepest point of the palate. If the percentage ratio of distances K1 to K2 is 36 % to 44 %, the type of palatine vault is considered to be mesopalatinal, more than 44 % - as dolichopalatinal, and less than 36 % - as brachypalatinal types.

EFFECT: method provides more effective and reliable diagnosis of dentoalveolar anomalies and planning of orthodontic treatment of patients in the period of permanent dentition due to objectification of determining the shape of the dental arch, based on measurement of the main morphometric parameters of the palatine arch.
