Abstract: In a jaw implant for oral, subperiosteal placement over the alveolar ridge of the maxilla or of the mandible, the implant forms a body which in cross-section, in the condition in which it has been placed on the alveolar ridge transverse to the alveolar ridge, has been formed concave towards the alveolar ridge, wherein in or near a first portion forming the base of the body, in particular forming the base of the J, L or U, the body has been provided with one or more supporting areas for support members, such as pillars, for extending through the gingiva, the support members forming a support for an exo-prosthesis, wherein the supporting areas have been connected to the rest of the body via relatively weakened areas of the body, in particular have been connected to the rest of the body via those relatively weakened areas of the body only.

Abstract: Prosthesis (1) for the mandibular side of a temporomandibular joint, comprising a head part (2) to replace the condylar head, in particular at the anatomic location, and an attachment plate, wherein the attachment plate is saddle-shaped having a lateral portion (3) and a medial portion (4) that have been formed and are intended for abutting both sides of the ascending branch of the mandible, straight below the arcuate notch in the upper end of the ascending branch of the mandible.
