Fig. 6From: Is one-stage lateral sinus lift and implantation safe in severely atrophic maxillae? Results of a comparative pilot studyKaplan–Meier survival curve for the probability of implant loss depending on the residual height of the alveolar ridge (< 3 mm or ≥ 3 mm). The time in months after augmentation and simultaneous implant placement was plotted on the abscissa. The ordinate indicates the cumulative survival probability, i.e., the probability that no implant loss occurredBack to article page
