How is AI Enhancing Bone Segmentation Techniques in Dentistry

Artificial Intelligence (AI) is increasingly transforming the healthcare industry by enhancing diagnostic accuracy, streamlining administrative processes, and personalizing patient care. Its role in healthcare is multifaceted and rapidly evolving, offering transformative benefits across various aspects of medical practice.

AI has a groundbreaking function in healthcare, including dentistry, where it can significantly enhance diagnostic accuracy, treatment planning, and patient outcomes.

Bone segmentation refers to the process of isolating and identifying bone structures from medical images or digital scans. This technique involves distinguishing bone from surrounding tissues and structures to create a detailed representation of the bone’s anatomy. Bone segmentation is a critical process in dental imaging and treatment planning, particularly in implant dentistry and orthodontics.

What is Bone Segmentation?

Bone segmentation in digital dentistry refers to the process of accurately delineating bone structures, particularly the alveolar bone, from dental imaging data such as cone-beam computed tomography (CBCT) scans. This process is crucial for various dental applications, including implant planning, orthodontic treatment, and assessing bone health.
