Abstract: Techniques for providing medical implants that have been custom-formed for a particular patient for surface treatment to alter properties of a surface of an implant component. A dental abutment implant component, custom-formed by removing or adding material or by providing an electronic or other specification for its fabrication, is provided to a third party for a surfaced treatment to be, performed. After the abutment with surface treatment is received from the third party, it may be moved to the patient's body. One preferred kind of surface treatment employs anodization of a dental metal material such as titanium to give a pink color for improved cosmetic results. Other kinds of surface treatment including bonding may also be used. A blank implant component that has a first portion compatible with a standardized implant component, and a second portion expressly intended to be custom-formed by removing material.
