Single-Tooth Replacement on an Existing Tooth.
Case Study: Alumina
A 20-year-old male presented with a trauma to tooth No. 7, which had occurred 3 weeks earlier. A preoperative radiograph revealed a major fracture to tooth No. 7, with no peri-apical pathology or changes to the alveolus. A pulp test was normal, and there appeared to be no periodontal concerns. As the patient had very unique, characterized teeth, he was concerned about the difficulty of matching a single tooth to the rest of his dentition.

Preoperative radiograph reveals a major fracture to tooth No. 7. An all-ceramic restoration was planned. Before tooth preparation, a shade tab was used to take a match for a NobelProcera alumina crown.

Treatment Using a Porcelain-Fused-to-Titanium Crown
A 41-year-old male presented on emergency with a fractured left maxillary second premolar. He was missing the upper left first molar, where he was planning to receive an implant in the next 6 months. The fractured cusp upper left second premolar had a previous root canal requiring crown coverage (an amalgam was already in place). The patient opted for placement of a porcelain-fused-to-metal crown to support the remaining teeth.

CAD design of the titanium alloy coping, which was then fabricated at a Nobel Biocare central manufacturing plant using titanium aluminum vanadium. Research has demonstrated marked improvements in marginal fit using the milled fabrication process. This image shows the excellent fit of the titanium on the crown die.
The clinician should ensure adequate removal of the tooth structure to provide porcelain plus the coping thickness of 0.4 mm to 0.5 mm. Close-up view of the final TiPFM crown, cemented with a self-adhesive resin cement. Titanium alloy is expected to offer strong, long-term esthetic performance.
