1. A transepithelial abutment for the attachment of prosthesis (P) with a dental implant (90), comprising three components:
an upper body (20, 25) where a dental prosthesis (P) or dental device (95) is to be arranged, with an upper base (23) and a lower base (24) both connected by a through hollow space (26) having an inner thread (21),
a lower body (30) to connect with the dental implant (90), with an upper base (70) and a lower base (33) connected by an inner housing (38), said upper base (70) of the lower body (30) having a planar surface around the opening of the inner housing (38) and the inner housing (38) having a seating (37) to receive the head (41) of a screw (40), wherein a first lower segment of the inner housing of the lower body extends along a first axis “a” and a second upper segment of said inner housing extends along a second axis “b” forming an angle with respect to said first axis “a” and being perpendicular to the upper base (70) of said lower body (30), and a screw (40) inside the inner housing (38) of the lower body (30) with the head (41) of the screw located above the seating (37),
the upper body (20, 25) being integral with the lower body (30), with the lower base (24) of the upper body (20, 25) introduced and attached in the opening of the housing (38) of the lower body (30) with permanent attachment means, thereby forming a single device where the screw (40) remains captive between both bodies (20, 25, 30), with movements of the screw (40) within the inner housing (38) of the lower body (30) limited by the upper body (20, 25), wherein said attachment means are welding between the two bodies (20, 25, 30).
