无牙颌患者“All-on-Four”种植即刻负重技术的发展与变迁

Development of “All-on-Four” immediate loading technology in edentulous patients

无牙颌患者的最佳修复方式一直是颇有争议的话题,随着口腔种植技术的不断发展,目前无牙颌患者种植修复重建面临的挑战是如何在保证修复质量的前提下降低手术难度以及患者的费用。"All-on-Four"种植即刻负重技术是目前临床研究的热点,其避免了复杂植骨手术,最大程度利用剩余牙槽骨量实现即刻负重,患者接受程度高,临床效果理想。然而"All-on-Four"技术也面临着诸多挑战,手术适应证、手术程序、修复方案以及修复并发症等仍有待商榷。本文将就"All-on-Four"种植即刻负重技术在临床应用中的发展变迁及其优缺点等方面展开讨论,为临床医生在临床实际合理应用提供参考。

The best way to repair edentulous patients has always been a controversial topic. With the continuous development of implant technology, the challenge for edentulous reconstruction is how to reduce the difficulty and cost of surgery while ensuring the quality of repair. "All-on-Four" technology is currently a hot spot in clinical research. It can maximize the use of residual alveolar bone to achieve immediate loading and avoid complex bone grafting, which is widely popular among clinicians and highly accepted by patients. However, "All-on-Four" technology also faces many challenges. Indications of surgical treatment, surgical procedures, prosthetic plans and prosthetic complications are still to be discussed. This article will discuss, summarize and reflect on the advantages and disadvantages of "All-on-Four" implant technology to provide reference for its rational use in clinical practice.
