Unlabelled:
The existing methods for determining the position of 1:3; 2:3 teeth make possible subjective decisions in the construction of complete dentures. The use of objective auxiliary methods and devices that ensure metric determination of the position of 1:6; 1:4; 1:3; 2:3; 2:4; 2:6 haven't been cited in the known literature.
Purpose:
We have set as a purpose to create a methodology that eliminates the subjective determination of the position of 1:3; 2:3 in complete denture construction.
Methodology:
With the help of teleradiographic analysis of frontal cephalometry we created a methodology that avoids subjectivity in 1:3; 2:3 preparation. We applied well-known dependencies in orthodontics. - The correlation between the dental arch and the sum of the incisors. - The first law of Izard. The intermolar distance is equal to half the distance measured between the points Z : Z. - The method for graphic depiction of the dental arch of the maxilla created by Hawley and Herbert and refined by Herbst.
Conclusions:
The prostheses fabricated according to our methodology with the help of frontal cephalometry provide the possibility to avoid subjectivity in the work of both the dentist and the dental technician. When the frontal teeth are arranged the cutting tooth must lie on the graphic and the side teeth are inscribed in the graphic. The application of frontal cephalometry is an auxiliary method for the arrangement of the teeth in complete dentures, that with its metric values introduces a new aspect in the exactness and the positioning of the teeth in the prostheses.
