The process of bone remodeling that occurs after tooth loss is responsible for the decrease in bone availability, which is considered a key factor for success in rehabilitation with dental implants. The loss of bone quality and quantity combined with pneumatization of the maxillary sinus are factors that limit the rehabilitation of the maxilla. Rehabilitation of the mandible is usually difficult due to bone loss in height, and positioning of the inferior alveolar nerve (IAN) that hinders the placement of conventional implants in posterior region. In this case report, we present a follow-up of total rehabilitation of the maxillary arch with placement of zygomatic implants associated with conventional implants in the anterior region (14 years of follow-up), treatment evolution of the mandibular arch through short implants until its failure and removal (after 11 years), and rehabilitation with full-arch prosthesis with 29 months of follow-up. It was observed in this clinical case a great predictability and reliability in rehabilitation with zygomatic implants, as well as a limitation of rehabilitation involving borderline events with short implants, which - despite their failure - can be indicated in cases of conservative treatments that postpone the indication of full mouth extraction and total rehabilitation with implants.
