as the remodelling algo-
rithm medium bone density control value. For the a and b parameters ruling the
growth and the decay of the bone tissue it is considered: a = b = 0.01.
The bone tissue remodelling results are presented with a grey scale as usual and
in each presented figure it is indicated the bone model medium apparent density.
Firstly each one of the load cases are independently analysed. The results
obtained for load case 1 are presented in Fig.
7.22
. It is possible to observe the
achieved apparent density distribution for four distinct medium bone densities.
The results regarding load cases 2, 3 and 4 are respectively presented in
Figs.
7.23
,
7.24
and
7.25
. In each figure are shown four distinct medium bone
densities obtained with the respective load case.
In order to obtain a trabecular architecture similar to the real trabecular dis-
tribution of the maxillary bone on the surroundings of the central incisor, it is
necessary to consider simultaneously the four load cases. For each load case are
considered 2,500 cycles per day, totalising 10,000 masticating movements per day.
Recall that the considered remodelling algorithm weights each load case in the
