DENTAL IMPLANT TO BE PLACED IN THE POSTERIOR UPPER JAW

摘要

The dental implant (100) for implanting in the upper rear maxilla (O) following the lifting of the sinus membrane (M) of the maxillary sinus (SM) by the crestal approach, comprises: a body (1) having a shank shape, comprising a main portion (10) and, on opposite sides with respect to the main portion (10), a first crestal proximal portion, (11), and a second apical distal part, (12); a threading (2) having a spiral shape with cutting edges (21). The threading (2) having a spiral shape with cutting edges (21) extends in spiral fashion only about and along the main portion (10) of the body (1) terminating before the second apical distal part (12), while the second apical distal part (12) is conformed in such a way as to comprise an external surface (14) free of projecting or cutting parts, and so that the external surface (14), at least partially, annularly has a groove (15) or a series of grooves (16).
