An inclined abutment (10) for a cemented prosthesis in dental implantology, comprising:- a supragingival portion (11) having a substantially truncated-cone shape with an elliptical base and having a longitudinal axis (X-X), hereinafter referred to as the longitudinal axis of the supragingival portion (11),- an emergence surface (12) coinciding with said elliptical base of said supragingival portion (11),- a transmucosal portion (13) which has an elliptical base coinciding with said emergence surface (12), a longitudinal axis (Y-Y) hereinafter referred to as the longitudinal axis of the transmucosal portion (13) and which ends at the apex with an antirotational connection (16) for the insertion of said abutment (10) in use, in which:said longitudinal axis (X-X) of said supragingival portion (11) and said longitudinal axis (Y-Y) of said transmucosal portion (13) form, relative to each other, a first angle (α; α'), comprised between 5 and 35 degrees, which angle defines the inclination of the abutment (10) in use, and- the lateral surface (11.1) of said supragingival portion (11) forms with said longitudinal axis (X-X) of said supragingivial portion (11) a second angle (γ), comprised between 2 and 6 degrees, which angle defines the conometry of said supragingival portion (11),and in whichthe volume of said supragingival portion (11) remains essentially constant upon variation of said first angle (α; α') of the abutment (10), when the dimensions of said emergence surface (12) and the height (h) of said supragingival portion (11) remain unchanged with respect to said longitudinal axis (X-X) of the same.
