Fig.1 shows two implants placed at the sites of the lower 2nd premolars after multiple surgical procedures: extraction, soft and hard tissue graft.  The patient experiences lower right lip paresthesia post implantation.  In my opinion, the depth and position of implant is difficult to control once the socket heals unless CT is taken every step of osteotomy.  It appears that immediate implant is a solution.
