Abstract
A Modified Functionally Generated Path Technique (FGP) for Making Posterior Unit Metal-Ceramic Crown
Highlights
The original technique was described by Meyer 73 years ago [1,2,3]
The technique has been known by various names such as “functional bite technique”, “generated path technique,” and “cuspal tracing technique”
The functionally generated pathways (FGP) of occlusion refer to the registration of the paths of movement of the occlusal surfaces of the teeth of one dental arch, to the teeth or occlusion rims of the opposing arch, recorded three-dimensionally in the functional wax with the help of a plastic medium with acceptable condylar and anterior guidance and normal occlusal anatomy [10,11,12]
Summary
The original technique was described by Meyer 73 years ago [1,2,3]. He termed it as the “chew-in” technique, and since various researchers have refined the procedure. A 30-year healthy female patient presented to the department of fixed prosthodontics at the dental clinic of Monastir for restoring her maxillary right 2nd premolar teeth She requested an esthetic and functional restoration. To obtain the functional core we used a simple artificial teeth support plate (denture tooth cards) as a which was loaded with creamy fast setting stone (snow white of Kerr) It was positioned on the occlusal surface of the quadrant so that it covered at least one tooth at the both sides of the prepared premolar (Figure 8). The functional core cast was mounted on the lower one These paths registered with a stone matrix will be used by the ceramist as a guide and the framework was casted in a Nickel -chromium alloy following standard laboratory procedures. The final prosthesis was cemented using glass ionomer cement (GC Fuji II, GC Corporation, Japan) (Figure 14) [17]
