Patent
CA 2054496
The invention relates to a spacing member arranged between a securing element (fixture) implanted in the facial bone (the cranium) and an extraoral prosthesis, in particular a facial prosthesis. The spacing member comprises a base portion (1) intended to cooperate with the upper portion of the securing element, and an extension part (8, 8') which forms an attachment point for the prosthesis. The extension part (8, 8') is designed in such a way that it permits attachment of~the prosthesis in a direction (attachment direction] which forms essentially a right angle to the longitudinal direction of the extension part. The spacing member combines the two conflicting requirements which exist particularly in the case of an orbital prosthesis, namely secure anchoring in the bone (radial,attachment of the securing elements) and a more favourable attachment direction (axial) for the prosthetic work.
