Implant Planning #10 with Poor bone?

The patient is a 39 yo female who underwent extraction of #10 two years ago without socket preservation bone graft. She has worn a flipper in the interim. She now wished to consider and implant. Evaluation of the available bone shows very narrow bone facio-palatally. Based on ideal implant position, additional bone would be required both on the facial and palatal. Very few options for reconstruction of bone. Suggestions? Thanks. LG
