A bone foundation guide with a bone foundation guide body contoured to guide a cutting implement to alter an exposed bone of a dental surgical site. The bone foundation guide body may form an encircled open surgical space that continuously connects a top and a bottom of the bone foundation guide body. The bottom may be further contoured to affix to the exposed bone of the dental surgical site while the top is further adapted to support a dental implant surgical guide or in the alternative a cutting containment guard. The cutting containment guard may have a cutting channel for receiving the exposed bone when the cutting containment guard is combined with the bone foundation guide body. The combination forms a cutting slot for guiding a cutting edge of a cutting implement to alter the exposed bone from the dental implant surgical guide.
