A dental surgery guide system for use with a surgical handpiece for a surgical intervention, notably for forming a bore in a patient's jaw bone to receive a dental implant, the dental surgery guide system comprising: - a surgical template adapted to be secured within the patient's mouth, the surgical template comprising - an opening that coincides with a surgical axis, notably an implant axis for the dental implant, to allow passage of a surgical instrument, notably to create a bore in the patient's jaw bone along the implant axis; - one or more template guide rails (4a, 4b), each template guide rail (4a, 4b) having its longitudinal axis aligned parallel to and offset from the surgical axis; and - a template stop (8, 15a, 15b); - a handpiece jig adapted to be secured to the surgical handpiece, said handpiece jig comprising: - one or more handpiece guides (11a, 11b), each handpiece guide (11a, 11b) being engageable with a respective template guide rail (4a, 4b), and - a handpiece stop (12a, 12b, 14a, 14b); wherein cooperation between the handpiece guide(s) (11a, 11b) and the template guide rail(s) (4a, 4b) restrains the lateral position and the axial orientation of the surgical instrument relative to the surgical template during the surgical intervention, notably during creation of a bore in the patient's jaw bone; and wherein the template stop (8, 15a, 15b) and the handpiece stop (12a, 12b, 14a, 14b) are adapted to cooperate to limit the position to which the surgical instrument can advance, notably during creation of the bore in the patient's jaw bone, and characterized in that the top of the handpiece guide (11a, 11b) can slide below the top of the template guide rail (4a, 4b). - a surgical template adapted to be secured within the patient's mouth, the surgical template comprising - an opening that coincides with a surgical axis, notably an implant axis for the dental implant, to allow passage of a surgical instrument, notably to create a bore in the patient's jaw bone along the implant axis; - one or more template guide rails (4a, 4b), each template guide rail (4a, 4b) having its longitudinal axis aligned parallel to and offset from the surgical axis; and - a template stop (8, 15a, 15b); - a handpiece jig adapted to be secured to the surgical handpiece, said handpiece jig comprising: - one or more handpiece guides (11a, 11b), each handpiece guide (11a, 11b) being engageable with a respective template guide rail (4a, 4b), and - a handpiece stop (12a, 12b, 14a, 14b); wherein cooperation between the handpiece guide(s) (11a, 11b) and the template guide rail(s) (4a, 4b) restrains the lateral position and the axial orientation of the surgical instrument relative to the surgical template during the surgical intervention, notably during creation of a bore in the patient's jaw bone; and wherein the template stop (8, 15a, 15b) and the handpiece stop (12a, 12b, 14a, 14b) are adapted to cooperate to limit the position to which the surgical instrument can advance, notably during creation of the bore in the patient's jaw bone, and characterized in that the top of the handpiece guide (11a, 11b) can slide below the top of the template guide rail (4a, 4b). - an opening that coincides with a surgical axis, notably an implant axis for the dental implant, to allow passage of a surgical instrument, notably to create a bore in the patient's jaw bone along the implant axis; - one or more template guide rails (4a, 4b), each template guide rail (4a, 4b) having its longitudinal axis aligned parallel to and offset from the surgical axis; and - a template stop (8, 15a, 15b); - a handpiece jig adapted to be secured to the surgical handpiece, said handpiece jig comprising: - one or more handpiece guides (11a, 11b), each handpiece guide (11a, 11b) being engageable with a respective template guide rail (4a, 4b), and - a handpiece stop (12a, 12b, 14a, 14b);
