Case Profile
This patient was an 86-year-old woman. The patient had been treated several times in the past. In the early years, the mandibular posterior teeth were implanted, and the entire maxilla was reconstructed at an outside hospital(Fig 1, Fig 2). However, over time, due to unsealed and discolored bridges that caused aesthetic and functional discomfort, the metal-porcelain crown of the maxilla fractured, and had to be replaced (Fig 3)
