A dental implant (1) comprising an endosteal body (2) from which a tapered transmucosal neck (3) extends, the transmucosal neck (3) having a free end (4) configured for mating with a stump (5), an outer surface of the transmucosal neck being shaped so that a first tangent (T1) to the outer surface in at least a first point (P1) proximal to the endosteal body and away from connecting surfaces forms with an axis of the dental implant a first angle (α1) smaller than a second angle (α2) formed between the dental implant axis (A) and a second tangent (T2) to the outer surface of the transmucosal neck (3) in at least a second point (P2) away from jointing surfaces and proximal to the free end (4). |
