From what HbA1c level is surgery possible?

Surgery is safest when HbA1c is controlled at 7.0% or below. In the 7-8% range we decide after reviewing your overall health and the scope of surgery, in consultation with your physician; above 8%, uncontrolled diabetes carries a high risk of infection and failed osseointegration, so we recommend controlling blood sugar first. For diabetic patients, Seoul Maeil Dental Hospital checks these together: 1) HbA1c within the last 3 months, 2) current medications, and 3) the post-operative antibiotic and disinfection plan. Diabetes does not make implants impossible - what matters is control.
