This is a rare one off vintage Denture made for a patient with lower mandible deformity. The dental prosthesis has been made in 2 parts, the lower part reconstructs and restores missing hard structures of the lower jaw and is specially hinged to gain easier access. Once in place the second part fits over it to provide a new set of lower teeth. You can see that the gum section is quite deep to align the teeth correctly in the patient’s mouth. Highly collectable museum quality item.
