PROBLEM TO BE SOLVED: To provide a method for calculating indicators for determining the necessity of jaw surgery in orthodontic treatment, the method enabling easy calculation of indicators for determining the necessity of jaw surgery that serve as objective material for a dentist to determine whether a patient requires jaw surgery in orthodontic treatment, and enabling the dentist to easily and quickly perform a more objective and accurate diagnosis by also taking the result of another examination method into account, as appropriate; and a program therefor.;SOLUTION: Indicators for determining the necessity of jaw surgery in orthodontic treatment are calculated by calculating P=((S-X_i)+(Go-X_j))/(S-A) (except in the case where X_i=B and X_j=Me) using the following measurements from a cephalogram of a patient: the distance (S-A) between S and A; the distance (S-X_i) between S and X_i (i is an integer between 1 and 4, inclusive, and X₁=B, X₂=Pog, X₃=Gn, and X₄=Me); and the distance (Go-X_j) between Go and X_j (j is an integer between 1 and 4, inclusive, and j=i or j≠i).;COPYRIGHT: (C)2014,JPO&INPIT
