Abstract

The project aims to develop a dental implant device, the technical appeal of which is in the combination and use of strong points from the two models currently most commonly used: the bi-cortical implant and bone integration. From the first model we will use the concept of the fixation of the device in the second cortical, drastically reducing the time for the placement of the dental prosthesis. From the second model we will apply the design of its crown, which offers a much greater capacity than the first in terms of esthetics, asepsis, and the monitoring of the prosthesis system in the replacement of front teeth and treatment of the active surface for a greater area of bone integration. Both are models that adopt titanium as the basic material for their construction, which will be retained in this project. The methodology to be used in the project follows sequentially the following activities: modeling and dimensioning of the prototypes; mechanical testing of wear and tear, compression and cutting ability between the conventional bi-cortical model and the model being proposed here; production of prototypes; and their implantation in animals.
