Jawbone prosthesis shanks meet at an angle of less than 70 around the periphery of an anchorage screw hole

摘要

#CMT# #/CMT# A jawbone prosthesis hinges against the skull. The prosthesis junction consists of an essentially triangular zone with an apex (a, b) of less than 70 that is bisected by a further section (d), all joining at the periphery of a circular hole (A). The section (d) adjoins a screw hole D also in contact with the periphery of sections (a) and (b). #CMT#USE : #/CMT# Jawbone prosthesis. #CMT#ADVANTAGE : #/CMT# The prosthesis has better rotational stability and more space for anchorage screws. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the prosthesis root zone. A : Screw hole D : screw hole a : cross-piece b : cross-piece c : cross-piece.
