Re-establishing natural tooth position in the endentulous environment.

The routine prosthetic arrangement of teeth set according to arbitrary criteria frequently results in adaptive problems, tissue damage, poor aesthetics, lack of stability and functional disabilities. A phonetic technique, based on the "S" position of the mandible, in the majority of cases provides a useful aid in achieving natural tooth positions and the occlusal vertical dimension. This technique can enhance the quality of prosthodontic service especially for patients having difficulties with full dentures.
