Treatment of severely resorbed partially or completely edentulous maxillae can include the utilization of the zygomatic process for immediate implant fixation and stabilization with immediate function. This approach may alleviate the need for significant grafting to enable implant placement in the posterior maxilla and allow implants to be placed into denser, more stable bone. Zygomatic implants, which have been used clinically for the past 20 years in the treatment of the severely resorbed maxilla, allow implant placement to support fixed prosthetics. Their usage can potentially shorten treatment time and reduce costs, as the need to wait for osseous graft maturation is eliminated. Guided surgical approaches are being utilized to maximize placement of the prosthetic platform of these implants.
严重吸收的部分或完全无牙上颌骨的治疗方法可包括利用颧骨进行即刻种植体固定和稳定，并实现即刻功能。这种方法可能减少对上颌后部进行大量植骨以实现种植体植入的需求，并允许将种植体植入更致密、更稳定的骨中。颧骨种植体在过去20年中已临床用于治疗严重吸收的上颌骨，可实现种植体植入以支持固定修复体。其使用有可能缩短治疗时间并降低成本，因为无需等待骨移植成熟。目前正在采用引导式手术方法来最大限度地放置这些种植体的修复平台。
