Total tooth loss can be accompanied by alveolar bone resorption, reducing the stability of conventional dentures and complicating traditional implant placement. Depending on anatomy and available bone, solutions such as zygomatic implants or All-on-4 and All-on-6 protocols may support a fixed prosthesis in selected cases. Each indication requires a clinical examination, 3D imaging, and a general health assessment. Digital planning helps select the technique, number of implants, and appropriate positions. These treatments aim to improve stability, chewing, and aesthetics; results and longevity vary according to bone condition, hygiene, smoking, and follow-up.
