Subperiosteal jaw implant

Abstract

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.

         10 . Assembly according to  claim 1 , wherein at least one of the segments has been configured for placement on the alveolar ridge at the location of the incisors and/or canine(s) and, in particular, has been configured for placement at one side of the median line. 
     
     
         11 . Assembly according to  claim 1 , wherein the jaw implant has been configured for placement on the alveolar ridge of the mandible. 
     
     
         12 . Assembly according to  claim 11 , wherein at least one of the segments/bodies has been provided with an extension, provided with one or more of the attachment holes, which extension has been configured for attachment to the corpus mandibulae and/or has been configured for attachment to the ramus ascendens mandibulae, in particular for attachment to the frontal edge (trigonum retromolare) of the ramus ascendens mandibulae, over the trigonum retromolare in the direction of the processus coronoideus, or lateral from the ascending branch of the mandible, dorsally extending. 
     
     
         13 . Assembly according to  claim 1 , wherein the jaw implant has been configured for placement on the maxilla.
