A method and devices for bone tissue expansion and compression for receiving a dental implant are disclosed. The method includes the steps of creating an initial osseotomy site in the maxilla or the mandable using a pilot drill; screwing a first threaded expander into the site to expand the site laterally; and allowing the expander staying in the site for a short time to impress the interior wall of the osseotomy site; then retrieving the first expander.
