Due to the progress made in implantology, in recent years the interest in prosthetic rehabilitation in edentulous mouths using overdentures has increased considerably. Indications to the treatment of implant supported overdenture could be classified in three groups: the first group consists of younger members of the elderly population who have an edentulous upper jaw rehabilitated with a conventional complete denture but experience discomfort with it and therefore desire a stable prosthesis and greater comfort in the mouth; the second group, for which the use of implant overdentures is recommended, consists of older patients who require greater stability from a complete mandibular denture; the third group consists of compromised patients and those with acquired or congenital maxillofacial conditions. Moreover, advantages of overdentures supported by implants are analyzed; in fact, they allow a lower bone reabsorption, a better retention and stability of the prosthesis than the traditional complete denture, an increased masticatory effectiveness, a reduction of pain during mastication tanks to the higher stability, a better sensory perception, a considerable patient satisfaction, and the option of making an immediate prosthetic rehabilitation with implants through immediate load.
由于种植牙技术的进步，近年来，使用覆盖义齿对无牙颌进行修复的兴趣大幅增加。种植支持式覆盖义齿的治疗适应症可分为三类：第一类是老年人群中的年轻成员，他们用上颌传统全口义齿修复无牙上颌，但对此感到不适，因此希望获得稳定的假牙并在口腔中获得更大的舒适度；第二类，建议使用种植覆盖义齿的是需要下颌全口义齿具有更高稳定性的老年患者；第三类包括身体有缺陷的患者以及患有后天性或先天性颌面疾病的患者。此外，还分析了种植体支持的覆盖义齿的优点；事实上，与传统全口义齿相比，它们能减少骨吸收，使假牙具有更好的固位和稳定性，提高咀嚼效率，由于稳定性更高而减少咀嚼时的疼痛，具有更好的感觉感知，患者满意度相当高，并且可以通过即刻负重用种植体进行即刻修复。
