As a result of reviewing this case study, the reader should:
- Understand the advantages of using Porcelain-Fused-to Metal-Restorations
- Learn techniques for the implementation of these restorations
The evolution of dental porcelains and advanced fabrication techniques has enabled clinicians and laboratory technicians to provide an increased quality of healthcare for their patients. While the collaboration of such professionals has permitted durable, aesthetic restorations to be fabricated with improved success and predictability, these efforts must be carefully planned prior to the initiation of a particular treatment.
Many clinicians once believed that only all-porcelain jacket crowns were capable of achieving optimal aesthetics in the restoration of the anterior dentition. Subsequent developments in material science have demonstrated that porcelain-fused-to-metal (PFM) restorations with a vertically reduced framework are also capable of providing the highest level of aesthetics, strength, and longevity to any substrate (ie, vital tooth, discolored or metallic cores). The utilization of a Geller framework improves the translucency of the restoration at the cervical aspect, eliminates shadowing effects, and incorporates the enhanced strength of a metallic substructure. In addition, this type of restoration does not require the use of expensive equipment or complex technical procedures.
This presentation emphasizes the laboratory protocol used to fabricate six maxillary restorations and highlights the considerations that must be addressed during the treatment. When these concerns are properly addressed by the restorative team, it is possible to develop an optimum final result in terms of shape, position, color, translucency, texture, and gingival integration.
