Acute submandibular and submental cellulitis develops with sublingual purulent discharge 1 month 10 days postop (Fig.16). CT confirms lingual plate perforation at both sites (Fig.17,18; red line: original socket). With block anesthesia, removal of these implants causes mild discomfort. With Hydrogen Peroxide and normal saline copious irrigation, pain reduces when anesthesia subsides. Bone graft will be placed at the sites approximately in 2 weeks.
