The beauty of Bicon implant is that the crown (Fig.6 C) can be extraorally cemented to the abutment (A) prior to re-seating. Two years and 3 months post cementation, while no residual cement is visible, the bone density at the crest has increased (Fig.7 arrowheads). The crown is de-cemented 4 years 4 months post cementation; it appears that the abutment is small and short (5x2 mm 10 degree stealth).
