Title: Replaceable fossa component for a temporomandibular joint replacement system
Inventor: DIMITROULIS GEORGE
IPC: A61F2/30
Filed: 2022-06-23
Abstract: A temporomandibular joint replacement system includes a condylar component secured 
with a mandibular bone and a fossa component with a fossa backing secured with a 
zygomatic bone and slidably attached with a removable fossa lining, the fossa lining 
having an open-ended concave fossa dome with a post-center peak to allow for 
mediolateral and anterior translation with a rounded, oblong condylar head of the condylar 
component. The slidable attachment mechanism of the fossa backing and fossa lining is 
laterally-oriented to allow for post-implantation removal and replacement without 
disturbing any bone or bone-interfacing components. The bone-interfacing surfaces are 
anatomically-contoured to their respective bone surfaces and formed with materials and 
textures which promote osseointegration with the joint replacement.
