The machine completed the etching, silanating, and adhesive cementing, and then conventional porcelain-polishing procedures were used to complete the process. The newer CEREC II system can create full-coverage ceramic crowns (Foerster 2). Beyond the greater technological ease, using such machines reduces the risk of tooth fracture between visits. Reduced treatment time and visits for impressions and provisional restorations reduces costs to the patient, and also to the military (Foerster 4). Most attractively for the military: "Finally, teeth can be restored without the services of a dental laboratory. This reduces the overall cost of the restoration and permits the restoration of teeth in remote locations where laboratory services may not be readily available" (Foerster.3). The value of such technology is not limited to the military, of course. Dentists working in clinical settings without laboratory services with such technology can still conduct such restorative work, once the initial outlay for the technology is made. Dentists with patients on limited or no insurance plans, by reducing dental visits, can also keep...
