The lengthwise extension of the aehae can be precisely designed to be concave or concave. Because of the arrangement of the sutures a larger SpanrewiB arises in the endangered place within the hats and contributes to the formation of Spanstasongen «

In addition, the incorporated hats have the effect that the ascending chip material from the new index teeth following the incision does not grasp the stepped siaru-laid tooth face so that a jamming of the drill and nut flanks is largely avoided. You risk of taps, which from ^. · Τ cause of the Binkleemen * ve "chip material is conditioned" is eliminated.
