Rehabilitation Of Severe Atrophic Maxila with Zygomatic and Pterygoid Implants: Case Report

Background: The absence of dental elements results in progressive bone resorption of the maxilla, leading to vertical bone loss with a gradual decrease in medullary bone, thereby hindering the rehabilitative process using osseointegrated implants. Zygomatic fixation protocols combined with pterygoid implants have proven to be viable alternatives for maxillary bones with severe bone resorption. Objective: describe, through a case report, the treatment protocol for atrophic maxilla using zygomatic fixation implants, complemented by pterygomaxillary implants through an immediate loading system over a twelve-month follow-up period. Results: All implants showed clinical and radiographic signs of osseointegration, and no pathology was detected. Conclusions: The technique appears to be effective without requiring, in this specific case, any prior procedures for reconstruction of the atrophic maxilla.
