Revolutionizing Orthognathic Surgery

Each year, millions of people worldwide are affected by jaw misalignments that compromise both appearance and function. These conditions can impair chewing, speaking, and breathing, and are often linked to facial imbalance and obstructive sleep apnea. Jaw Surgeries- so called Orthognathic surgery –  offer a definitive correction by repositioning the jaws to achieve proper alignment between the maxilla and mandible. However, conventional workflows typically require patients to undergo several months of presurgical orthodontics, delaying the benefits of surgery and extending overall treatment time.

An alternative method known as “Surgery First” reverses this sequence—performing the surgery at the beginning of treatment, followed by orthodontic finishing. This approach can significantly shorten treatment duration and enhance patient satisfaction. Despite growing interest from surgeons, orthodontists, and patients, widespread adoption has been limited. The primary barrier lies in the complexity of interdisciplinary coordination between surgical planning and orthodontic systems, which have traditionally operated in isolation.

RevOS is a digital solution developed to bridge this gap. Designed as an intelligent plug-in, the software connects aligner treatment planning tools with surgical simulation platforms, enabling a cohesive workflow across disciplines. By accurately predicting the ideal post-surgical occlusion and tooth position, RevOS allows clinicians to plan and execute Surgery First cases with greater efficiency, predictability, and clinical confidence. The result is a fully digital, integrated process—from diagnosis and surgical planning to aligner-based orthodontic finishing.

Currently advancing from concept to prototype, the project aims to bring modern jaw correction techniques to a broader patient population. Early feedback has highlighted a clear demand for such an integrated planning tool. Patients benefit from fewer invasive steps, shorter timelines, and improved quality of life. Orthodontists gain a more predictable and efficient treatment course, while surgeons are empowered to expand indications and achieve consistent outcomes.

The development team combines the academic and surgical expertise of maxillofacial surgeons from Charité—one of Europe’s leading university hospitals—with the practical insight of an experienced orthodontics specialist. The team is further supported by one of the world’s key opinion leaders in the ‘Surgery First’ approach, ensuring scientific rigor, clinical relevance, and global best practices.
