Crown & Bridge Kit for crown and bridge preparations. The DIATECH Diamond instruments have a uniform coverage of diamond on different levels. New diamond grits with sharp edges will, therefore, be exposed for use during procedures as the outer layer wears. Universal application is possible due to the conical shape and the rounded edge of the preparation e.g. occlusal reduction with coarse grit diamonds. The convergence angle of 6 degrees delivers an ideal retention shape of the crown core. The margin preparation for the metal ceramic crown will become bevelled using the conical tip of the cylindrical finishing bur. The rounded end of the diamond preparation instrument provides a rounded, inner margin preparation. Contains 5 different diamond burs with FG-shanks and an easily sterilized bur holder.
