Permanent cheekbone implants for large forward projection, young male? To what extent can cheek implants be customized?

Both implants and fillers in the cheeks can create good results for patients.  Both can build up the cheeks and create contour.  You must balance the pros and cons of each procedure and do what you feel is the best decision for you.
Fillers:
Pros: No downtime Reversible Quick
Cons: Temporary More expensive in long run
Implants Pros: Permanent Great for patients with poor bone structure Less expensive overtime
Negative: Risks associated with surgery Possible infection Downtime
I hope this helps!

 Cheek implants are manufactured in a large assortment of sizes, thickness and shapes. They can be custom carved when necessary to match patients unique anatomy, especially when there is  asymmetry.  Cheek implants are placed for patients to have a flat maxilla and a flat cheek profile. Cheek implants are placed through an intra-oral approach under brief general anesthesia as an outpatient surgical procedure. Anticipate visible swelling and bruising for two weeks and full healing takes several months.
