PFM Restorations Transform Patient's Smile

Luke Kahng, CDT · Technical · Apr 2013

  • Figure 1: Before: Pre-operatively, the patient's smile reveals "piano-type" teeth that are flat, square and not uniform.

  • Figure 2: After impressions were taken and models poured, the UCLA abutments were fabricated by waxing and casting them in metal.

  • Figure 3: At the lab, the abutments were surveyed with a milling machine in order to verify parallelism and proper fit.

  • Figure 4: The bridges were waxed up, cast in precious metal and then tried in and measured horizontally to check the incisal edge positioning. A measurement was recorded with the metal frameworks in the mouth.

  • Figure 5: The porcelain buildups were layered onto the frameworks using GC Initial MC. Kahng measured from tissue to incisal edge to ensure the restorations were the proper length and contour, and used enamel overlay to decrease the bulk of the teeth. In order to create the gingival areas, he used pink porcelain. To fabricate the single crown, he did a traditional waxup, cast it in metal and then used GC Initial MC porcelain for the buildup.

  • Figure 6: The final restorations.

  • Figure 7: The screw-retained bridges and single crown were placed in her mouth to check fit, then cemented in place.

  • Figure 8: After: Both the dentist and her mother-in-law are very happy with the lifelike restorations and the patient reports a newfound confidence in her smile.

  • Figure 9: The happy patient.
