Implant-Protected Occlusion is that occlusal scheme which reduces the forces at the crestal bone/implant interface. Biomechanical principles form the basis of this concept. The direction of force, force magnification, and implant position relative to arch or location are blended together for a consistent approach to implant reconstruction. The direction of force demonstrates that angled forces increase the type of forces, alter their point of application, and reduce bone strength. Force magnifiers include cantilevers, offset loads, and monumental forces to the implant body. These magnifiers dramatically increase the among of force applied to a prosthesis. The implant position relative to arch or arch position often determines the density of bone and the amount of force. Adequate surface area of implant bodies considers width, length, and number. The surface area is a primary component in the resistance of force factors. In addition occlusal table width and occlusal contacts contribute to the force amount type and direction and may be modified to reduce crestal loads.
