When a 4.5x11.5 mm implant is placed (>35 Ncm), palatal threads are exposed, to which autogenous bone and Vera Graft (Fig.5 *) are placed with a 5.5x5(3) mm abutment. The distal implant threads remains exposed 6 months postop; it appears that the distal socket wall (Fig.7 <) has resorbed (Fig.8).  That is a probable reason that the distal threads are exposed.  The sockets heal 1 year 7 months post cementation (Fig.9).
