Disclosed is an assembly of: a jaw implant for oral subperiosteal placement over the alveolar ridge of a patient's maxilla or mandible； dentures； and supports for the dentures on the jaw implant, spaced apart therefrom. The dentures selections from right premolars and right molars and other from incisors, canine, premolars and molars left of the median line, and/or selections from left premolars and left molars and selections from incisors, canine, premolars and molars right of the median line. The implast is divided into segments or bodies configured for respective placement in different areas of the alveolar ridge, spaced apart from one another in arc direction of the alveolar ridge. The dentures include a bridge part that is bending-rigid under the intended loads that occur and has an arc length that suffices to connect the segments to each other via the supports.
