Clinical Trial Summary

Dental implant supported screwed prosthetic rehabilitations are associated to several advantages, as a minimal occlusal spaced and easier hygiene and maintenance. In this sense, screwed rehabilitations have been associated with lower frequency of biological and technical complications. Nevertheless, the screwing process results in the formation of a prosthetic chimney that requieres an appropriate sealing protocol. This protocol needs to include a material for the protection of the screw head. Nowadays, there is a lack of materials for this intended use with marketing authorisation. Several materials have been tested in the bibliography including PTFE, although there are not high quality studies. In this context, this clinical investigation aims to evaluate the efficacy and safety os a PTFE-based product (MAFILL) for the sealing of prosthetic chimneys and the protection of the screw head.
