Abstract
The prosthesis loading force is an important factor for dental implant survival. Even
if adequate osseointegration of the dental implant has been achieved, if the occlusal
forces are not correctly distributed, lateral torque can be generated causing high
stress on surrounding tissues. The stress value of implant prostheses could be different
whether the direction of load is vertical or oblique, affected by the shape of the
occlusal surface. When an implant-supported prosthesis is designed with a dental computer-aided
design software program, the average vectors from each occlusal contact point can
be visualized. If the visualized vector generates lateral torque, the occlusal surface
design can be modified before finalizing the design. The described technique uses
automated vector analysis to enable visualization of the occlusal vector to improve
prosthesis design, optimizing occlusal forces.
