These TADS are made in USA, and now available online and are shipped within 24 hrs.  We have on staff an orthodontist and an oral surgeon available for email support.  We also have a training video produced by one of the early adaptors of this product, Dr Jack Fisher.  Securus orthoTADS are the first to use a compound thread design, whereby the fine thread engages the cortical bone after the coarse thread guides the implant thru the softer medullary bone.
