PAs taken nearly 6 months postop show no bone loss (Fig.5,6).  The definitive crown is cemented with access hole; there is no residual cement (Fig.7 (9 months postop)). The crown is loose 1 month post cementation (last March, Fig.8 with periimplant space (*)).  Retrospectively, the periimplant space exists as early as 6 months postop (Fig.5,6).
