Dental scheme according to Triadan

In 1972 he developed a dental scheme for animals that has been used worldwide since then. In doing so, he was based on the FDI human tooth scheme , which was developed in 1960 by the Berlin university professor Joachim Viohl .

A quadrant is one half of the jaw. The dentition thus consists of four quadrants. In the FDI scheme, the quadrant number is placed in front of the code number of the tooth. The quadrants are numbered counterclockwise from the patient's point of view, starting with the upper jaw on the right. The teeth, in turn, are numbered from the center backwards. The upper right canine is labeled with the code number “13”. The "1" stands for the upper right quadrant, the "3" for the third tooth calculated from the middle. The lower left first premolar is given the code number "34". The deciduous tooth quadrants are numbered accordingly from 5 to 8,

In the Triadan tooth scheme - to differentiate it from the FDI tooth scheme of humans - the tooth numbers are counted from the middle towards the throat starting with a "0" after the quadrant numbers. It is also called the three-digit system. Accordingly, the upper right first incisor is named "101" (one - zero - one), the lower left canine ( canine ) is named "304" (three - zero - four).
