Noble Replace CC Rotated After 4 Months of Healing

Authors

This case involved an otherwise healthy individual, non-smoker who underwent implant placement 4 months ago, presented for restorative appointment during which implant Nobel Replace CC 3.5x 11.5 in area #11 rotated about 1/8 of the turn and resulted in some discomfort for my patient. High resolution small view CT was ordered and area was evaluated. CT showed that implant was placed well within the borders of the maxillary wall. I am certain that since the implant has turned, it only means that I start with day 0. Thus, should more time be given for osteointegration, or should I replace the implant with longer implant? Please note that the reason 3.5 diameter implant was utilized was because mesial-distal space available between teeth 10x12.
