One-Piece Root-Form Implants: A Return to Simplicity
Immediately loaded 1-piece dental implants were a standard treatment modality more than 30 years ago and, on occasion, resulted in excellent clinical successes. However, this technology also became associated with significant failure rates and fell out of favor. Since then, understanding of the site requirements and placement procedures necessary to ensure primary stability have advanced considerably. Implant designs and surface treatments also have evolved. In light of this greater understanding, a 1-piece root-form implant system has been developed. This article describes 4 clinical cases in which use of the new system was employed. In each case, the results included excellent stability, esthetics, and patient satisfaction.Abstract
The implant features an integral fixed abutment and is available in several diameters, including 4.3 and 3.0 mm (shown here). Figure 2.
