A Computerized Method for Evaluating Distribution of Occlusal Load on Implant-Supported Fixed Cantilever Prostheses

An investigation was conducted to determine whether Dental Prescale, a material that undergoes a graded color-producing chemical reaction when force is applied, could be used to evaluate occlusal load distribution objectively and quantitatively when combined with computer analysis. Ten patients with an implant-supported fixed cantilever prosthesis and a complete conventional maxillary denture were studied. The results indicated that the system can be used to evaluate occlusal load distribution with sufficient reproducibility. However, in its present form, the system is somewhat cumbersome, and its use must now be considered experimental. Further refinement is necessary to allow easier clinical use.
