A surgical stent for accurately positioning an implant in the most optimum bone structure of a patient that includes a negative impression of the area of the implant having a guide formed as an integral part of the negative impression that has either a top opening or a lateral side opening for receiving and guiding a surgical tool or drill that forms the implant sight. The guide is orientated relative to the negative impression so as to direct and guide the surgical tool along a most optimum trajectory as established by a diagnostic evaluation of the implant sight to insure that the implant seat is placed in the patient's most optimal bone structure. In one form of the invention, the guide is defined an a tubular or cylindrical member having a side entry for the surgical tool. In another form, the guide is defined as a guide surface having point or lines of reference that function as a guide which allows the surgeon some discretion is deviating from the theoretical optimum trajectory if necessitated by unforeseeable anatomical problems.
