Abstract: The present dental prosthesis has a palatal implant configured to be implanted subperiosteally and attached to the palatal process by a plurality of fixation screws. The implant has a spine retaining implant magnetic components therealong and having holes for the fixation screws. The prosthesis also has a maxilla denture having a palatal base plate and an alveolar ridge engaging periphery having false teeth installed thereon. The denture is configured to be placed in a mouth to engage a maxilla wherein the alveolar ridge engaging periphery engages an alveolar ridge of the maxilla. The denture comprises a plurality of denture magnetic components configured to align with the implant magnetic components so that the denture is magnetically retained in the mouth by magnetic attraction force between the implant magnetic components and the denture magnetic components.

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.

Abstract: An orbital implant adapted for attachment to the very thin bone at the orbit rim (502), such as the zygomatic and frontal bone margin at the supero-lateral aspect (501) of the orbit (503), for the attachment of an eye prosthesis directly to distal ends of inwardly convergently orientated transdermal abutments. The orbital implant has a baseplate (100) having an orbit radius curvature and an orbit rim curvature and a plurality of microfixation apertures therethrough and the plurality of transdermal abutments are located at an inner edge of the baseplate (100).

Abstract: There is provided herein a bone anchored implant that is used to support a nasal prosthesis in patients with a missing external nose. The implant consists of central section (which is preferably generally triangular) suspended within the aperture of the nasal cavity by four fixation arms which extend radially to engage the surrounding maxillary bone. The triangular portion may support three fixation points, one at each corner of the triangular portion, which in turn, directly engage the nasal prosthesis either via magnets or mechanical locking interface. Extending radially from the triangular section, the four fixation arms may flatten to a clover leaf arrangement of three apertures which accommodate micro-screws that secure the implant to the surrounding maxillary bone.

Abstract: An anatomically-contoured subperiosteal jaw implant includes an annular-shaped baseplate and internal support arms corresponding to a location of a plurality of height-adjustable posts. The baseplate is configured for placement over the alveolar ridge of a mandible or maxilla bone and creates a plurality of internal apertures within the baseplate to minimize the impact on the alveolar ridge and improve re-attachment of bone and soft tissue revascularization after implant insertion. The baseplate is attached with the bone via a series of screws inserted through screw holes uniquely positioned throughout the baseplate based on individual anatomical models of a patient receiving the implant, and the height-adjustable posts are also shaped for partial insertion into the bone to reduce the height of the posts and attached dental component while also improving retention of the implant. The support arms absorb stress on the posts received via a chewing or grinding action of the jaw.

Abstract: There is provided herein a surgical procedure for cancerous mandibular reconstruction and a temporary mandibular spacer therefor. The spacer is a structural load-bearing and rigid/stiff interim space maintenance device that can be used by surgeons to temporarily bridge the gap across a resected part of the mandible. The device may be made of a rigid and biocompatible polymer material which is anatomically shaped like a natural mandible. During surgery, the mandibular spacer may be quickly cut with a surgical saw into the desired lengths by the surgeon which may more precisely match the resected segment of native mandible. The length and the shapes of the terminal ends of the spacer may be configured to more precisely maintain the position of the remaining mandibular segments in their original locations and thus preserve the occlusion and surrounding soft tissues in their correct anatomical positions, reducing or eliminating scarring and/or malocclusion.
