Question 129 · LDEK · Bridges
Traditional bridges should not be applied:
1) in class III and IV, VI according to Applegate and Kennedy without modification;
2) when the angulation between the long axes of abutments is greater than 25°;

4) in epileptic patients;
5) in the case of large alveolar resorption in an edentulous area;
6) after trauma and 11, 12 tooth avulsion in children between 6 and 12 years of age.
