An accurate and precise surgical guide for dental procedures, especially a procedure involving a subject with few or no teeth as well as methods for making and use of such guides.

A method of conducting a sinus lift procedure is provided. A secure and physical interaction is formed between a fiducial device and a site within a patient's mouth to form a fiducial marker. A virtual incising plan is formed for incising the patient's maxilla, with respect to the fiducial marker, for providing access to a sinus membrane. Movement of an incising device is physically regulated with respect to the fiducial marker with a guidance device. The incising device is in physical communication with the fiducial marker via the fiducial device. The guidance device physically regulates movement of the incising device, according to the virtual incising plan and corresponding with physical manipulation of the incising device by a user, to incise the maxilla. Tactile feedback is provided to the user, via the incising device, if the physical manipulation of the incising device by the user deviates from the virtual incising plan.

The invention relates to a device for penetratingly extending a blind hole into a hard tissue, particularly a jawbone. The device is characterized in that it comprises a tubular body (1) having a distal working opening (2) and an inlet (3) opposite the working opening (2), said inlet being closed by a sealing element (4) that is penetrated by a shaft (5) of a working tool, for example a milling tool (5, 6), and allows at least a feed motion, a drive motion and a steering motion of the working tool (5, 6), the tubular body (1) being provided with a connection (8) for applying an internal pressure.
