The patient returns 10 days postop with chief complaint of light UL, LL pain. There is plaque over the healing abutments; the gingiva slightly erythematous and tender. She feels better after plaque removal. Amoxicillin is prescribed 1 more week.
Six days later, "pain is less". Percussion of #13 healing abutment causes headache. There is no mobility at #13 or 14. The buccal gingiva is severely erythematous and edematous at #14. Chlorhexidine irrigation is conducted. After removal of the slightly subgingival healing abutment without pain, a 6x7 mm one is placed with severe pain. After local anesthesia, the implant seems to be mobile. The new abutment is advanced ~ 1 mm (Fig.5). Augmentin is prescribed. One week later there is no sign or symptom of infection. It appears that Augmentin should be prescribed after sinus surgery.
