An affixation device for a human skull may include a base plate that has an outer area for securing to the skull and an inner area for securing to a bone flap removed from the skull. The affixation device may also have at least one spacer located between the outer area and the inner area, where the at least one spacer extends from a first surface of the base plate, where the first surface facing the skull when the fixation device is in an installed state, and where the at least one spacer is configured to extend between the bone flap and the skull in the installed state.

A fixation device includes a base, a bracket positioned above the base, and a fastener connecting the bracket and the base. The base is configured to be attached to a first surface, such as a skull of a patient. The bracket includes an upper portion, a lower portion, and an intermediate portion connecting an end of the upper portion to an end of the lower portion. The lower portion is configured to be attached to a second surface, such as a bone flap removed from the skull of the patient. The fastener connects the upper portion of the bracket to the base. The fastener is configured to pass through at least one of an opening in the base and an opening in the upper portion of the bracket to incrementally adjust a distance between the base and the upper portion of the bracket.

An assembly comprising a cranioplasty prosthesis component having a connection hole(s). A pivot fastener may have a body being threaded and adapted to be screwed to cranium bone. A shoulder is between the body and a head of the pivot fastener, the shoulder having a circular section. A diametrical dimension of the circular section is less than a diametrical dimension of the connection hole, such that the shoulder forms a rotational joint with the cranioplasty component when the shoulder is in the connection hole.

An implant for at least partially filling a bore hole in a bone includes a biocompatible plate and a support structure. The support structure has a ring-shaped inner support frame having an outer surface defining the outer diameter of the inner support frame and an inner surface, and an outer support frame having a plurality of fastening points adapted for attaching the implant to bone surrounding a bore hole in which the plate is inserted. The outer support frame is connected to and extends away from the outer surface of the inner support frame. A method of forming the implant is also provided.

A continuous fiber-reinforced build material for additive manufacturing (AM) of fiber-reinforced composite (FRC) structures, a machine for the preparation of the build material, and use of the build material for manufacturing of three-dimensional (3D) FRC end-product devices, such as medical devices for management of musculoskeletal and dental disorders.
