A six-year follow-up study of maxillary overdentures on osseointegrated implants.

This study comprised a clinical and radiological examination of two groups of 14 patients receiving overdentures of the same design on osseointegrated implants. The mean follow-up period was 82 months and 35 months in the two groups the fixture success rate was 84% and 85% and the marginal bone loss 0.97 mm and 1.29 mm respectively. The follow-up of the two groups was guided by several clinical parameters and apart from the loss of fixtures and adjustments of the attachment system only a few complications were registered. The results show that this treatment method is a successful alternative in the treatment of the edentulous maxillae.
