A 5x11.5 mm UF implant is placed as deep as possible (Fig.5 before bone graft) so that there is less chance of implant thread exposure and stability increases (insertion torque: 35/50 Ncm). ^: sinus floor.   No sticky bone or PRF is used.

Five months postop, there is a gap, especially distally (Fig.9).  The best treatment to fill the gap will be orthodontic extrusion of the 3rd molar.
