Mobile bearing prosthetic implant system

A temporomandibular joint implant, comprising:

• a fossa implant comprising a first jaw angle recess and a second jaw angle recess constructed and arranged to mimic the natural anatomy of the articular eminence of the temporal bone and sized and configured to receive a floating bearing therein;
• a ramus implant comprising a ramus plate, a stem extending from the ramus plate, a tapered neck extending from the stem, and a spherical bearing extending from the tapered neck, wherein the stem, the tapered neck, and the spherical bearing being at least partially offset from the ramus plate in a plane parallel to that of the ramus plate;
• and
• a spherocylindrical floating bearing snap-fit onto the spherical bearing of the ramus implant, wherein the spherocylindrical floating bearing is sized and configured to move from the first jaw angle recess to the second jaw angle recess,
• wherein the fossa implant comprises Ti-6Al-4V, wherein the ramus implant comprises Ti-6Al-4V, and wherein the spherocylindrical floating bearing comprises polyetheretherketone (PEEK),
• wherein a longitudinal axis of the spherocylindrical floating bearing is perpendicular to the direction of movement of the spherocylindrical floating bearing within the fossa implant,
• wherein the first jaw angle recess is constructed and arranged to position a jaw at a 0-degree jaw angle accounting for closed jaw offset,
• wherein the second jaw angle recess is constructed and arranged to position a jaw at a 25-degree jaw angle accounting for closed jaw offset,
• wherein the first jaw angle recess defines a first floating bearing profile, wherein the second jaw angle recess defines a second floating bearing profile, and wherein the first floating bearing profile is different from the second floating bearing profile, and
• wherein the first jaw angle recess and the second jaw angle recess are configured to allow the ramus implant and the spherocylindrical floating bearing to mimic natural movements of a jaw by allowing the movement of the spherocylindrical floating bearing.
