According to the X-ray taken 1 year ago (Fig.4), a long tissue-level implant (6x17 mm) is suitable for the site. In accordance with CBCT (coronal section, Fig.5 (palatal on the right of the image) taken prior to RCT (2 years ago from now), a short bone-level implant (6.9x10 mm) is a more reasonable choice. The implant should be placed buccally.
