A 51-year-old lady had the crown at #18 cut off because of open margin in the other office lately. The margin was found and confirmed too subgingival to be restored. Three years ago, the tooth #31 was extracted and replaced by an immediate implant (7x11 mm (trajectory off, light blue, Fig.1 (CT 3 D image)). The implant is close to the Inferior Alveolar Canal (orange) and the Submandibular Fossa (SF).
