Abstract

The use of conventional intraosseous implants may be limited or inapplicable in restoring some edentulous spaces due to various anatomical reasons. The Cortically Fixed at Once approach (CF@O) uses the remaining cortical bone to fix specially designed implants. This implant system was developed to meet challenges in patients with severely resorbed jaw bones. The CF@O protocol requires no bone graft, no sinus lift or nerve displacements. The CF@O implant system consists of several types of components specifically developed for different locations in the jaw. These components are Pterygoid implants, compressive implants and hybrid plates. The Pterygoid implants and the Hybrid plates are developed to be placed in the posterior zones of the maxilla. The compressive implants with specific macro- and micro-threads are used in the cortical and spongy bone, mostly in the frontal bone of the upper and lower jaw. The hybrid titanium plates are thin, lightweight and highly flexible, which allows them to be adapted to any bone anatomy and fixed with osteosynthesis screws. The presented case reports describe the surgical and prosthetic steps followed for the functional restoration of an edentulous patient with the CF@O implant system. Rehabilitation of difficult edentulous cases is achieved within a short period of time. CF@O incorporates the whole range of treatment procedures available to the implantologist, and it is a reliable alternative where there is substantial bone resorption.
