This method provides support for appropriate implant procedures using three-dimensional data representing the oral cavity. [Solution] This is a support device for assisting in implant procedures that include multiple components. The support device comprises an acquisition unit that acquires three-dimensional data showing the three-dimensional shape of the oral cavity including the jawbone; a calculation unit that determines the position of each of the multiple components in the oral cavity based on the three-dimensional data acquired by the acquisition unit and adjusts the position of at least one of the determined multiple components based on the positional relationship of the multiple components; and an output unit that outputs support information showing the position of each of the multiple components after adjustment by the calculation unit.

The disclosure provides compositions and methods for directing the growth of blood vessels in a tissue graft. The compositions and methods provide the advantage of directing the growth, size and pattern of blood vessels from the periphery of the graft, which recapitulates or improves the native blood vessel orientation in the host tissue. The compositions comprise a tissue graft that comprises a matrix attached to a barrier. The barrier comprises a porous membrane that permits passage of water and nutrients but blocks blood vessel growth. The methods comprise implanting the tissue graft on a host tissue in a subject and incubating the graft on the host tissue such that blood vessels grow around the edges (periphery) of the barrier or through intentional internal openings in the barrier and into the matrix. The methods can further comprise transplanting the vascularized tissue graft to a second location in the subject. Thus, the methods can be used in a staged implant procedure to create autologous, vascularized bioengineered tissue grafts.

The present technology includes inserter instruments for use with medical implant procedures. The inserter instruments can include features that are expected to enable the inserter instruments to be accurately registered with off-the-shelf or conventional surgical navigation systems. For example, the inserter instruments can include a retractable implant coupling element. The retractable implant coupling element can be selectively transitioned between (a) a first configuration in which the implant coupling element extends past a distal end of a shaft of the inserter, and (b) a second configuration in which the implant coupling element is retracted inside the shaft such that it is flush with, or positioned proximally of, the distal end of the shaft.
