What are the contraindications for full-arch reconstructions?

Active gum inflammation must first be fully treated. Uncontrolled diabetes increases the risk of infection by 40 to 60%. Smokers (more than 10 cigarettes a day) have a 3 times higher rate of implant failure. Osteoporosis medication (bisphosphonates) carries a risk of jaw necrosis. Insufficient bone volume with no option for bone augmentation. Psychological conditions that hinder compliance with aftercare. Unrealistic aesthetic expectations on the part of the patient. Financial constraints affecting the complete treatment and aftercare. Dental anxiety that makes regular check-ups impossible. Previous radiotherapy in the jaw area (depending on the dose). Multidisciplinary assessment is essential for managing these risks.
