CASSOS is a first of its kind in surgical simulation software product developed in Hong Kong and includes comprehensive medical records and image management functions of specific relevance to orthognathic surgery - surgery in which the bones of the face are manipulated to restore proper anatomic and functional relationship in patients with dentofacial bone anomalies.

An integrated and highly interactive system operating on a cost-effective PC Windows platform, CASSOS offers customizable lateral and frontal cephalometric analysis, surgical planning and soft tissue change prediction for orthodontic and orthognathic maxillofacial
surgery.

CASSOS saves time for surgeons, brings high accuracy to the task of facial construction and enhances patients-doctors communications. Its specially developed algorithm is at the heart of the first ever simulation system in Asia for orthognathic surgeries. CASSOS has been adopted by major hospitals in Hong Kong, China, South Asian and European
countries.
