Technical Comparison: PVD vs Traditional Treatments
Implants add biocompatibility paperwork on top of everything above. That path is described in medical PVD coating.

When quotes are compared side by side, ask each shop how they control substrate preparation before coating — the answer shifts the total more than the hourly rate does. Ours runs through the quote page; the process detail is on the finishing and coating page.
