Tooth reconstruction tenon, has projection prolonged towards upper end of head by truncated portion, which forms guide ramp facilitating introduction of tenon into dental cavity while projection allows retention of removal of impression

摘要

The tenon (1) has a tenon head (2) prolonged by an intra-radicular rod (3) intended to be impacted in a root of a tooth to be reconstructed. The head is intended to receive impression paste and comprising a retention and positioning unit that includes a retention projection (7a) or an upper projection. The projection is prolonged toward an upper end (12) of the head by a truncated portion (8a), which forms a guide ramp facilitating introduction of the tenon into a dental cavity while the projection allows retention of removal of impression.
