Multi-material stiffness-matched implant devices and fabrication methods

A method of fabricating a device for bone graft, replacement, or abutment, comprising:

• obtaining a non-resorbable portion made of a non-resorbable biocompatible material;
• obtaining a resorbable portion made of a resorbable biocompatible material, wherein the resorbable portion is configured to be resorbed in a pre-determined timing such that mechanical properties of the device are modulated to avoid stress shielding of a bone and to control stress concentrations in the device below a predetermined level to avoid failure of the device;
• and
• joining the non-resorbable portion and the resorbable portion to form the device.
