Filling material pin for a root canal of a tooth

摘要: The invention relates to a filling material pin (1), comprising flexible and used for root canal (6) of tooth, wherein the is memory material, which expands upon heating tooth or body temperature in form volume change. exterior (1) profiled at least across length thereof that effective use position such regions having both larger smaller cross-sections alternate axial direction, can be achieved particularly useful simple manner by means helical, threaded, worm shape profiling, simultaneously pushes an added cement even better deeper into pivoting inserted (6), thus allowing air contained therein escape.
