TOOTH STUMP STRUCTURE, PRODUCTION METHOD AND DESIGN THEREOF |
摘要 |
A method for producing a tooth stump structure that is to be anchored in a root canal comprises the following steps: flexible needles are introduced one after the other into a recess in the form of a root canal or into an exposed cavity; the length of the protruding ends of the needles is adjusted to the form of a core of the stump structure, the core is then modelled from a semi-liquid, polymerizable composition and subsequently hardened; and an outer jacket of a crown is applied to the core. The tooth stump structure produced by said method is formed by a structural core made of a hardened composition, wherein individual flexible needles are anchored in said core and protrude therefrom, a cross section of the needles being circular, elliptical or polygonal and their diameter ranging from 0.1 to 0.8 mm. The protruding parts of the needles occupy a space that corresponds essentially to the space of the root canal or the cavity. |
