摘要

使用四个颧植入物（ZI）对萎缩的上颌骨进行全弓康复已经成为一种广泛的解决方案，使我们能够绕过植骨手术。然而，由于假体代偿体积的差异，腭假体出现固有的骨骼差异会给患者带来明显的不适。一位60岁的患者，上颌完全无牙，严重萎缩，骨骼为III级，被转介到我们进行完全康复。我们使用一种创新的手术指南，在一次手术中完成Le Fort I型截骨术，放置四个颧骨植入物，并立即加载螺钉保留的氧化锆桥，而无需假体补偿。结论颧骨种植和正颌康复，采用定制的手术指导，可以在颌骨严重萎缩的情况下，单次手术修复即刻加载假体的口腔功能。

Rehabilitation of the atrophic maxilla: Guided Le Fort I maxillary advancement and zygomatic implants with and immediate loading

Introduction

The full-arch rehabilitation of the atrophic maxilla using four zygomatic implants (ZI) has become a widespread solution, allowing us to bypass bone grafting procedures. However, the palatal prosthetic emergences inherent to the skeletal discrepancy cause significant discomfort for patients due to prosthetic compensations volume.

Observation

A 60-year-old patient, completely edentulous at the maxillary with severe atrophy and a skeletal Class III, was referred to us for full rehabilitation. We use an innovant surgical guide to perform the Le Fort I osteotomy, placement of four zygomatic implants, and immediate loading of a screw-retained Zirconia bridge without prosthetic compensation in one single surgery virtually planned.

Conclusion

Zygomatic implant and orthognathic rehabilitation, using a custom surgical guide, offers an accurate solution to restore in a single surgery, the oral function with an immediate loading prothesis when the maxilla atrophy is severe in skeletal Class III.

期刊介绍： Oral and Maxillofacial Surgery Cases is a surgical journal dedicated to publishing case reports and case series only which must be original, educational, rare conditions or findings, or clinically interesting to an international audience of surgeons and clinicians. Case series can be prospective or retrospective and examine the outcomes of management or mechanisms in more than one patient. Case reports may include new or modified methodology and treatment, uncommon findings, and mechanisms. All case reports and case series will be peer reviewed for acceptance for publication in the Journal.
