Apparatus for preserving interdental papilla and method for using |
摘要 |
An emergence cuff (30,30') formed of suitable biocompatible synthetic plastic is shown having a bore adapted to be received on an abutment in turn mounted on a root marker implanted in the alveolar ridge of a patient. The cuff has a bore (36) generally matching the crown receiving surface of the abutment and an outer surface which goes from a feathered edge portion with the bore a first end (34,34') closest to the root member and a larger outer surface at the second end. The gum tissue is sutured onto the cuff and abutment so that after sufficient healing when the cuff is removed a sulcus is formed to receive a crown with the interface of the crown and the abutment located below the gum line. The emergence cuff can also serve as the cervical portion of a temporary crown (40) by attaching it thereto as by using a mechanical interlock (39), if desired. An optional radially inwardly extending flexible lip (48) is shown at the first end to provide a positive seat for the cuff member on the abutment.
