A 60-year-old patient complains about difficult mastication due to the mandible displacement that resulted from an untreated fracture. Objectively: the 35, 36, 38, 45, 46 teeth are missing. The remaining teeth are intact. The 43, 44, 47, 48 teeth have no contact with the upper lateral teeth, and exhibit oral deviation up to 1 cm. What is the optimal prosthetic construction for the manible?
