Immediate Rehabilitation of the Extremely Atrophic Mandible with Fixed Full-Prosthesis Supported by Four Implants
The purpose of this article is to prospectively assess the outcome of immediate rehabilitation of extremely atrophic mandibles by a full-arch fixed bridge anchored to four implants. All patients were followed for a minimum of 1 year (range 20–48 months, mean 30.1 months). No failures were
recorded to date. The 1-year implant survival rate and prosthesis success rate were 100%.Marginal bone loss around axial and tilted implants was similar at 12-month evaluation, being, respectively, 0.6 1 0.3 (standard deviation) mm and
0.7 1 0.4 mm. High patient’s level of satisfaction was recorded for function, phonetics, and aesthetics.
