During a recent CE course, ROE gained some valuable insight from Matthew Palermo DDS, Interim Chair Department of Restorative Dentistry at Temple University. One recommendation is the use of densely radiographic cement for implant seating. With the prevalence of peri-implantitus, the ability to observe and remove cement is critical, and TempBond and ZincPhosphate are ideal. He suggests checking your current implant cements for radiopacity.
Keeping the amount of cement to a minimum is advantageous. Dr. Palermo shared a method of minimizing the amount of cement using an extra-oral technique. Apply one thickness of Polytetrafluoroethylene (PTFE) inside a crown and then fill it with bite material. Before setting, insert a cotton tip. Once set, remove this plug and fill the crown with cement. Reinsert the plug (essentially creating a duplicate of the prep) until excess cement exudes; then quickly deliver the crown. This will provide approximately 50μ of cement.
