Prefabricated Precision Dowels

摘要: Prefabricated, high-fusing, precious metal precision dowels, developed by the au­ thors, have a diameter and taper equal to of new stand­ ardized files reamers. An easy, timesaving method for root reinforcement which can be used either direct or indirect technic is introduced. The dowels are small in gain frictional resistance displacement their adap­ tation pulpal walls increased length three-fourths four-fifths root. There were no frac­ tures from shearing stress dis­ placement masticatory function 60 cemented over six-month period.
