FABS3D AI is an innovative platform that utilizes AI technology to create 3D digital twin simulations, allowing clinicians to visualize treatment outcomes in dental, oral-maxillofacial, and aesthetic procedures prior to actual intervention. It converts patient photographs and 3D scans into precise digital models, automates cephalometric analysis, and produces structured clinical reports. By consolidating multiple planning tools into one integrated solution, the platform significantly reduces treatment planning time by about 90% and decreases costs per case, ultimately enhancing workflow efficiency and supporting more predictable clinical decision-making. It further connects oral health with broader clinical factors such as TMJ function, craniofacial posture, sleep, and the oral-gut axis. FABS3D AI aims to elevate clinical treatment planning by offering AI-driven simulations, automating crucial diagnostic workflows, and enabling dental and oral healthcare professionals to make more accurate and evidence-based decisions for adult patients.
