This educational 3D animation describes the surgical procedure for cleaning a Covered Socket Residuum (CSR) in area 32. It outlines the anatomical considerations of the alveolar and lingual nerves in the lower jaw and emphasizes the importance of nerve localization for safe treatment. The steps include surgical access planning, flap design and reflection, creation of a bony window, removal and debridement of the CSR, handling of tissues for histological analysis, bone regeneration using sticky bone and a collagen membrane, and primary wound closure.
