Use of short implants (6 mm) in a single‐tooth replacement: a 5‐year follow‐up prospective randomized controlled multicenter clinical study

Abstract

The results of this study showed that 6-mm-long implants supporting single crowns loaded within 7 weeks from installation lose a small amount of marginal bone during 5 years of functional loading, similar to that of 10-mm-long implants. However, a higher degree of implant loss was recorded at the short implants, probably due to the fracturing of the surrounding bone.
