We present a study about the importance of proper design of the screw head depending on the use it has to offer.
After presenting the key concepts in the design of products so that they can carry out the purpose for which they are intended, we speak of the importance of close collaboration between end users (dentists and prosthetic) and the world of engineering for the correct design and optimal operation of the tools for medical use.
One of the most common situations of a dentist and a laboratory technician is the undesired emergence of the implants. In this paper we present the solution of key-screw connection BHS30.
It is a study on the causes of breakage or loosening of the prosthetic screw and its relationship with the protocols of use of these products.
The article concludes that instructions regarding handling and recommendations of torque defined by the manufacturer using appropriate tools and protocols established preload allow us to minimize the failure rate of implants for mechanical reasons.
