[Mechanical studies on the dental bridges. (XI) Studies on the apportionment loads to be affected by the supporting conditions of two abutment teeth (author's transl)].
Abutment teeth have been treated as the elastic behavior at the supported conditions and apportionment loads are depended upon the elastic properties of the pontics and abutment teeth. So, this paper shows the apportionment loads of dental bridges and the dependence of the elastic constants of abutment teeth. Abutment teeth are rotated and sinked with digestive power on the pontics. So, the elastic constants of abutment teeth are given with k and K, which k, K are the sinked and rotated coefficients, which are expressed the elastic properties of these abutment teeth. Apportionment loads to be connected with the flexural rigidity of the pontics are calculated for two numerical examples (for the values of 3.6 x 10(3) kg-mm2 and 3.6 x 10(8) kg-mm2 of the concentrated and distributed loads).
