Primary stability is obtained with a 4.5x20 mm implant (I, > 60 Ncm, Fig.4).  The gap (*) will be bone grafted.

Bone regenerates around the implant 3.5 months postop (Fig.7 *), but the 2nd molar has shifted mesially (arrow) without keeping the immediate provisional. The implant crown is functioning 4 years 2 months post cementation while there is severe bone loss at #2 (Fig.8).
