The clinical and laboratory steps involved in rehabilitating the maxillary arch following the loss of several teeth due to periodontal disease are outlined in this case report. This article illustrates the use of a laboratory based CAD/CAM system (Sirona In-Lab) and a copy milling technique in the fabrication of a fixed-movable bridge, high strength, all-ceramic, cross-arch bridge.
Patients' attitudes towards and expectations from dentistry have risen dramatically over the past few decades.1 This has highlighted the importance of attention to detail during the planning and execution of a course of dental treatment. This has increased the pressure on the clinician and technician and the interface between them.
Periodontal disease is a leading cause of tooth loss and the prosthetic management has conventionally been in the form of removable partial dentures.2 However, both clinicians and patients are showing an increasing tendency to approach this issue with fixed bridgework. Since Nyman et al published their seminal work in the 1970s,3 the prosthetic management of periodontitis has included bridgework acting as a fixed splint for periodontally involved teeth. A fixed-movable approach in fixed bridgework is sometimes necessary to allow for non-parallel paths of insertion, abutments with questionable prognoses and to incorporate attachments for the retention of removable prostheses.
