Exemplary embodiments of the present disclosure are directed towards an implantable device for complete replacement of temporomandibular joint comprising of a condyle component to reconstruct a mandibular end of the temporomandibular joint designed for movement within the implantable device with a plate; and a condyle surface where the plate is configured to mechanically secure the condyle component to a ramus surface of a patient undergoing implant with the aid of screws; and the condyle surface polished to generate a mirror effect to reduce the friction in the implantable device and infection rate; a zygomatic arch component to reconstruct a temporal bone (glenoid fossa) of the temporomandibular joint comprising at least one of: a plate; a plurality of multiple threaded counter sink holes; a plurality of conically tapered holes and a zygomatic arch surface, whereby the multiple threaded counter sink holes are structured within the plate; and a fossa component configured to be positioned between the condyle component and the zygomatic arch component to anchor the movement of the temporomandibular joint and the fossa component comprising of a low density biocompatible material made of a polycarbonate which is utilized in the additive manufacturing for the synthesis of implantable device for temporomandibular joint.

Medical devices, such as implants, and corresponding methods of manufacturing using an additive manufacturing technique, wherein the finished medical devices include a build plate retained therein, are disclosed. In some embodiments, the medical device includes a build plate having a plurality of peaks and a plurality of indentations, the plurality of peaks and the plurality of indentations together defining a surface roughness of an exterior surface of the build plate. The medical device may further include a first layer formed atop the exterior surface of the build plate, the first layer comprising a plurality of powder structures disposed over the plurality of peaks and the plurality of indentations. In some embodiments, an average peak distance between adjacent peaks of the plurality of peaks is less than an average width dimension of at least a portion of the plurality of powder structures.

The improved glenoid fossa prosthesis for repair of a scapular deficient patient includes a base with a fixed flange, and a separable flange. A conical taper on the base and a complimentary locator edge positively orient the separable flange when joined with the base for affixation by screw. A plurality of flange fixation screws penetrates the scapular tissue between the flanges for affixation of the flanges thereto. The flange thickness is variable to approximate the topography of the scapular tissue in the affixation area to minimize tissue trimming during fitment. A cutting mask attaches to the deficient scapula in the glenoid fossa area to guide the physician in trimming scapular tissue for fitment. A cortical screw further fixates the base to the scapular tissue. A second conical taper on the base serves as a mount for a glenoid sphere (reverse shoulder) or socket (standard shoulder) repair configuration.

The present technology provides patient-specific vertebral implants. The implants can include a cage having a geometry contoured to mate with an inferior surface of a superior vertebra and a superior surface of an inferior vertebra at a first target position. The implants can also include a plate having a geometry contoured to mate with an identified anatomical structure at a second target position. The cage and plate can be coupled in a predetermined three-dimensional orientation that simultaneously permits the cage to occupy the first target position and the plate to occupy the second target position when the implant is implanted.

A method of treating a patient in need of an orthopedic implant is described. The method includes obtaining the T-score or bone density of the patient's native bone at a site of implantation, said T-score or bone density being determined by a DEXA scan or other means of determining a T-score or bone density. The method further includes selecting an orthopedic implant that has about the same density as the native bone at the site of implantation, and implanting the orthopedic implant at the site of implantation.

In one aspect, an implant for replacing subject tissue includes a nonbiologic portion and a biologic portion grown on the nonbiologic portion. The biologic portion may be grown on the nonbiologic portion before being implanted in the subject. The nonbiologic portion may comprise a porous metal substrate (e.g., scaffolding). The nonbiologic portion may be formed by 3D printing (i.e., additive manufacturing). The nonbiologic portion may be patient-specific. A robot may be used to shape the implant before implantation and/or to shape bone being replaced/resurfaced.

An intervertebral fusion mechanism includes a disc cage having a scaffolding structure to support bone growth and a porous cancellous bone feeder anchor, connected to the disc cage, for providing a biological material transference interface between cancellous bone and the disc cage.

An artificial replacement disk configured to be positioned in between a superior vertebrae and an inferior vertebrae. The upper and lower surfaces match the surface morphologies of the corresponding vertebrae and may be textured to promote bone in-growth. The artificial replacement disk may comprise gripping structures to permit easy manipulation of the artificial replacement disk during surgical procedures.

Novel articles of manufacture based comprising lattices based on trabecular bone, having a plurality of plates and interconnecting rods. The trabecular bone-inspired lattice may be designed based on the general alignment of plates and rods found in trabecular bone, including anisotropic lattices having one or more predominant axes of mechanical strength. Lumbar fusion implants and other implants are provided having a trabecular bone inspired lattice in which bone graft material may be packed and providing a scaffold for bone fusion and growth. The implants may be based on bone structures having a predominant axis of mechanical strength and may be deployed in sites with the predominant axis of mechanical strength aligned with the primary axis of mechanical stress, such as in the the spine.

A system and computer-implemented method for manufacturing an orthopedic implant involves segmenting features in an image of anatomy. Anatomic elements can be isolated. Spatial relationships between the isolated anatomic elements can be manipulated. Negative space between anatomic elements is mapped before and/or after manipulating the spatial relationships. At least a portion of the negative space can be filled with a virtual implant. The virtual implant can be used to design and manufacture a physical implant.
