Abstract
The “quad zygoma” concept involves the insertion of four zygomatic implants, with adequate anteroposterior spread and correct inclination for the distribution of forces, as a means of rehabilitating patients presenting insufficient bone height in the anterior and posterior maxilla. The technique has been clinically tested using protocols for immediate function, obtaining promising short- and long-term results. Non-alveolar implants offer a predictable alternative to bone augmentation techniques in situations of severe alveolar atrophy. Other alternatives, like bone grafting procedures present certain complications derived from the technique itself and from the waiting times of the patients, which make alternatives such as zygomatic implants take more strength as a choice in patients with severe maxillary atrophies. Based on this, and in the literature and clinical experience, the use of four zygomatic implants with an immediate loading protocol is a viable option for rehabilitating patients with severe maxillary atrophy and appears to offer an excellent alternative to bone grafting procedures.
