There is minimal thread exposure after removal of the provisional nearly 2 months postop (Fig.6). The provisional does not return for easy self cleansing (water pik). In fact this is not an easy task, because of the posterior position (Fig.8 (after Piezo scaling)). The distal implant remains exposed; the abutment is removed and a healing screw is placed (Fig.9). The implant should have been subcrestal distally (Fig.7 <, nearly 3 months postop).
