Abstract:
:Microducers and modified cephalometric roentgenogram techniques were used to study maximum biting forces and moments in an adult male. The force at the second molar was approximately 10% greater than that at the first molar. At the second molar, the moment of force was approximately 15% less than its value at the first molar.
