The management of screw channels is critical in the life cycle of an implant restoration, and existing options present many limitations. For that reason, they cofounded 35Newtons®, and along with it, the FirstPlug® system — a medical-grade polytetrafluoroethylene (PTFE) screw channel barrier and instruments.
