The taper of a UF extra wide implant is minimal (Fig.5).

An ideal immediate implant should be as wide as possible coronally to close the socket, while the apical diameter should be much smaller (Fig.6) so that less amount of bone will be removed (compare Fig.5,6 red cross areas) and insertion will be much easier, as show later.
