Malchiodi L, et al. - Authors gauged the success of posterior implants tilted >45° when 4 immediately loaded implants were used to support full-arch prostheses, eliminating any distal cantilever. They also evaluated the impact on marginal bone loss (MBL) of different combinations of the anterior multi-unit abutment (MUA) angles and posterior implant tilting angles. Findings suggested a similar safety of posterior implants tilted >45° to eliminate distal cantilever as compared with those tilted less in severely atrophic jaws rehabilitated with immediately loaded, full-arch prostheses supported on 4 implants.
