Fig. 1From: Extra-short implants (≤ 6.5 mm in length) in atrophic and non-atrophic sites to support screw-retained full-arch restoration: a retrospective clinical studyBone-level measurements. Distances between the IP (implant platform) and the first bone implant contact coronally (BLm, bone level mesial; BLd, bone level distal) were measured and calibrated based on the known lL (implant length).
