Dental implants can be used to replace one, several, or all teeth in the dental arch. This versatility is one reason why they are so popular. Patients can eliminate their partial dentures by placing implants where needed and switching their complete dentures to all-on-4 dentures, which utilize four dental implants along the arch to stabilize a more conservative denture in the smile. Because of the solid foundation of the dental implant, these restorations are strong and durable, functioning like natural teeth.
