Occlusion Analysis Mounted Case - CDT Code Guide
Overview
CDT Code D9950 pertains to occlusion analysis using a mounted case, a critical procedure in diagnosing and planning dental treatments. This process involves the use of a facebow, interocclusal records, tracings, and potentially a diagnostic wax-up to accurately assess the patient's bite and occlusion. It is essential for identifying occlusal issues that may affect the patient's dental health or complicate future dental procedures. Dental professionals use this code when they need a comprehensive understanding of the patient's occlusion to inform treatment planning. This analysis is particularly useful in cases involving complex restorative work, orthodontics, or when there are signs of occlusal dysfunction.
