title: A maxillary subperiosteal implant design that maximizes bone support and accomodates a cemented, low-profile parallel guiding planes Hader bar.
abstract: A design for the maxillary subperiosteal implant is detailed that (1) simplifies construction, (2) maximizes underlying bone support, (3) minimizes posterior forces to the "egg-shell"-thin bone under the maxillary sinuses, and 4 (accommodates the low-profile, cemented, parallel guiding planes Hader bar. This implant design maximizes bony support for the maxillary overdenture. It places the Hader bar superstructure within a precise envelope that maximizes esthetics, proper phonetics, and acrylic bulk for long-term serviceability.
