Who is a good candidate for All-on-4 implants?

Ideal candidates are patients with significant tooth loss or failing dentition in one or both arches, who have sufficient jawbone volume to support four implants. It is particularly suited for those with moderate bone atrophy who might otherwise require bone grafting. Contraindications include uncontrolled systemic diseases (e.g., diabetes, osteoporosis), active periodontal infection, heavy smoking, or conditions that impair healing. A thorough preoperative evaluation, including CT imaging, is mandatory to assess bone density and overall health.
