A 3-year prospective cohort on the incidence of prosthodontic complications associated with three implant treatment options for the edentulous mandible.

All patients were at risk of post-delivery prosthodontic complications and required regular recall visits to achieve satisfactory function and to prevent further problems. Overdentures required higher rates of maintenance visits, particularly for replacement of the retentive inserts, while fixed implant prostheses required longer clinical times for management of complications when compared to overdentures.
