Bleeding is a risk associated with this procedure; it can happen during or after the procedure, which might originate an emergency surgery. Remember that taking aspirins and anti-inflammatories 10 days before surgery can increase the risk of bleeding.
Your body might reject the implants; if that happens they must be removed. This rejection can happen days or months after the procedure. Another risk is infection. This is not common but if it happens, the patient might need antibiotics and revisit surgeries, which will generate extra costs assumed by the patient.
Poor wound scarring is another rare risk. These scars can show a different color from the skin around it and be noticeable. The patient might need supplementary treatments including additional surgeries to treat this complication.
To avoid additional unnecessary complications, you need to consult a professional physician and verify the surgical facility of the procedure.
