Fig. 1. Design of the initial type of superstructure with space between the crest and the bridge to allow for cleaning procedures. Tightly adapted superstructure in the upper jaw.
Fig. 2. A closely adapted bridge construction in the upper jaw.
Fig. 3. The bridge has been removed annually to examine the gingival tissue.
Fig. 4. Adaptation of the superstructure to an irregularly formed alveolar crest in the upper jaw.
Fig. 5. Periodic identical intraoral radiographs in the upper jaw one year (A) and five years (B) after the fixture installation and the bridge adaptation.
Fig. 6. Periodic identical intraoral radiographs of implants in the lower jaw after the bridge connection (A) and four years later (B).
Fig. 7. Periodic identical radiographs in the upper jaw of a patient with thin alveolar crest showing initial remodeling and marginal bone loss (A). The situation becomes stable when comparing radiographs four years later (B).
