A 2.5x12 (2) mm 1 piece implant is placed (Fig.2). The patient returns for final impression 5 months postop: there is minimal bone resorption at the distal crest (Fig.10). 

There is no further bone resorption 11 months post cementation, while bone density immediately next to the implant appears to increase (Fig.21 arrowheads).
