The implant not only acts as an anchor to upright #18 in 4.5 months post banding (Fig.7 *), but also as an occlusal stop so that #18 has no interference to be moved. The stress on the implant results in radiating trabecular pattern (Fig.7,11 (9,11 months postop), as compared to before loading (Fig.1,3)).
