Evidence suggests immediate loaded single implant crowns have higher failure risk

Cross section of a dental implant

This review originally published in 2009 has now had a critical summary of it prepared under the auspices of the American Dental Association Center for Evidence-Based Dentistry

The  appraiser considered that this was a good systematic review that had used accepted methods and applied rigourous selection criteria.  There was homogeneity among  the 5 studies included  but they all has small sample sizes and were of short duration.

The  limited available evidence indicates  that  immediately loaded single implants (with crowns) are at higher risk of failure.
