Implant Options for Narrow Ridge on #11?

Authors
This 52 yo female lost #9, #10, #11 and #12 in a MVA trauma. I am planning a 3 unit implant bridge to replace #9-#11 and a single Implant to replace #12. Please enclosed photos. #9, #12 have adequate alveolar width for a 4 mm implant. The alveolus for #11 is narrow. I was thinking about using the Versah drill protocol to widen the ridge to allow a 4 mm implant. I have not used the Versah technique yet. Advice about the #11 site? Thanks. LG
