The provided sample points in the script are arbitrary and for demonstration purposes. For accurate cephalometric analysis, use landmark coordinates from an actual cephalogram.
This repository contains a Python tool for basic cephalometric analysis using landmark points. It provides functions to calculate critical angles such as SNA, SNB, and ANB and determines skeletal relationships based on these angles.
- Calculation of angles between given points using the dot product.
- Determination of maxillary and mandibular positions (prognathism or retrognathism).
- Classification of skeletal relationships as Class I, II, or III.
Define your landmark points as tuples with x and y coordinates:
S = (x1, y1)
N = (x2, y2)
A = (x3, y3)
B = (x4, y4)
CS = (x5, y5)
CE = (x6, y6)Run the provided script to calculate and print out the angles and classifications.
Output: The script will provide the following outputs:
SNA, SNB, and ANB angles. Maxillary and Mandibular position (Prognathism or Retrognathism). Skeletal relationship (Class I, II, or III). Additional angles such as CSA (Cranial to A-point) and CSB (Cranial to B-point). Notes: The provided sample points in the script are arbitrary and for demonstration purposes. For accurate cephalometric analysis, use landmark coordinates from an actual cephalogram.
