I have had a chance to use your Xpanders for about a month, and I have found them to be a remarkable aid in extracting teeth. I have practiced dentistry for over 40 years with my practice limited to the placement of implants by referral. The ability to predictably remove teeth (fractured, root canal treated, ankylosed etc.) and still allow for the immediate placement of an implant is a real plus to me and my patients. You know full well how many “gadgets” come across our desks in the course of a year, and a lot of them end up in a box somewhere. Congratulations on designing an instrument that is a “go to” instrument for extractions.
