ABSTRACT A dental implant system to provide a mechanically self- sufficient artificial tooth possessing a functional pseudo peridontal ligament that does not cause resorption of the supporting bone and ultimate loss is disclosed. The im- plant includes a core component that withstands the masti- catory loadand transmits such load to the root system. The root system comprises an outer component that adheres to the jawbone and possesses a similar modulus of elasticity thus capable of transmitting masticatory stresses along its interface with the bone without excessive stress concentrations and an intermediate component adhering tightly to both the core component and the outer component and having a much lower modulus of elasticity than either the core com- ponent and the outer component. The longitudinal movement of the core component causes the oblique or diagonal stretch- ing of the intermediate component which pulls or applies a force on the outer component which tends to contract it and creates tensile stresses in the portions of the supporting jawbone which interface with the outer component. Such tensile stresses cause bone deposition and stabilize the implant further.
