Currently the implant-prosthetic
therapy is widespread and has a great success regarding the rehabilitation of
edentulous patients. Although in many studies it has been reported a high rate
success for this type of treatment, in daily practice is very difficult to
avoid failures that consist in different complications such as mechanical or
aesthetic ones, resulting in relatively short term or late loss of the dental
implants.
This is the reason why the
researchers’ concern has been focused on finding the appropriate ways to increase
the success rate of the implant prosthetic therapy. Randomized clinical
trials and in vitro studies such as the finite element analysis are necessary
to assess the efficiency of the biomaterials and of the biomechanical aspects
of all the components, including the surrounding bone.
The success or failure of the
implant-prosthetic treatment is influenced by the stresses developed in the
periimplant bone and the stress values and distribution that depend both on the
implant and the bone characteristics.
