[IMZ implants in the treatment of the shortened dental arch in the upper and lower jaws].

The aim of this study was to evaluate the long-term prognosis after insertion of 510 IMZ-implants in case of free-end situations of the upper and lower jaw and prosthodontic restoration. We examined 222 patients prospectively who were treated in a dental practice because of uni- or bilateral free-end situation between 1984 and 1996. Affected and crowned teeth which were neighbouring the implant-based suprastructure, were blocked with these by use of bridge-restorations or attachments.
