An apparatus for achieving a variable height trans-tissue extension (TTE) useful in matching a prosthesis to an underlying implant fixture to preserve soft tissue shape, improve hygienic care and prevent a dissimilar metal, electrolytic effect below the tissue line. The trans-tissue extension consists of a set of aligned, non-rotating spacers with a through-hole for an attachment screw. The full height is achieved by using the tallest of the spacers, while a shorter extension is formed from the use of a shorter spacer. This simplifies the needed inventory of variable height abutments by anticipating a wide variety of needs. The trans-tissue extension is adaptable to single implants, bar undercases, ball-end, snap-on prostheses and casting or brazing forms.
