Fig. 1From: The effect of choline-stabilized orthosilicic acid in patients with peri-implantitis: an exploratory randomized, double-blind, placebo controlled studyRight images (b, d): Cone beam computed tomography (CBCT) slices illustrating the measured parameters: distance from implant shoulder to first bone-to-implant contact (IS-BIC; blue) and distance from implant shoulder to alveolar crest (IS-AC; red) at the lingual, buccal, mesial and distal aspects of the implants. The level of the implant shoulder (IS) and the long axis of the implant are marked in green. Left images (a, c): 3D volume rendering of the jaw and the cross-sections (yellow plane) made to perform the measurements illustrated in the images on the right. The measurements were performed on two perpendicular planes passing through the long axis of each implant and oriented mesio-distally and bucco-orally, respectivelyBack to article page
