Fuzzy Logic as a Bridge to Human-like Artificial Intelligence in Orthodontics: A New Perspective

Applications of artificial intelligence (AI) are increasingly becoming an indispensable component of orthodontic practices. The number of AI studies focused on orthodontics is growing rapidly. The fundamental operations of the AI algorithms utilized in these studies typically rely on binary logic (black or white, or 0 or 1). However, binary logic does not fully reflect the complexities of real life. Reality is more nuanced, with shades of gray and irregularities. Therefore, fuzzy logic-based AI systems, which mimic human-like reasoning, may facilitate more optimal and realistic decision-making in the healthcare and orthodontics fields. This article aims to introduce the concept of fuzzy logic to orthodontists, demonstrate its application through clinical case examples, emphasize the importance of adopting a fuzzy logic approach in treatment planning, and raise awareness among orthodontists about the potential for fuzzy logic AI to play a more prominent role in orthodontic practice in the future.
