I saw this patient (47 years old) for extraction of her maxillary left canine and lateral incisor and placement of a graft, 3 months prior. I recommended extraction of all remaining maxillary teeth and replacement with implants. She has a generalized, aggressive form of periodontitis and many of her teeth are mobile and with a poor long term prognosis. She has declined the treatment plan. What do you recommend as a predictable treatment plan?
