This study compares the prognosis of HIV patients from three groups, one involved in regional mobility, another in cross-border mobility in search for healthcare and the reference group which is composed by patients living in the same city of the health facility.

[Biomechanics of implant retained fixed prosthesis in patient with edentulous upper jaw].

The purpose of the study was to study the stress-strain state of bone tissue and a permanent prosthesis on implants installed in the frontal part of the upper jaw. The 150N load was applied to the frontal and 250N to the side of the non-removable prosthesis on six or four implants, including zygomatic and 'All-On-Four' technology. The values of stresses in bone tissue, implants and prosthesis are obtained, which show a large margin of strength in structural materials.
