The Guide Right (TM) Setup Disks are used in place of a prosthetic wax up or a plastic prosthetic tooth. One or more setup disks are chosen to set on a cast to space the center of the implants appropriately. The setup disks allow one to drill through the disk into the cast of a patient with a partially edentulous arch with a 3/32" drill. The guide posts are placed in the 3/32" hole(s) in the cast after the setup disks are removed. Set includes all setup disks.
