Methods and systems for tracking a dental tool within an oral cavity for taking and/or updating of a dental impression are described. In some embodiments, a marker, optionally a magnetic marker, is coupled to position movements of a rotatable dental tool. In some embodiments, detected movements of the marker are used, optionally in combination with other tracking data, to map contours which a portion of the rotatable dental tool follows during interaction with a dental surface. Optionally, the interaction occurs during grinding, drilling, and/or other procedures; which may be preparatory, for example, to the manufacture and/or fitting of a dental prosthetic.

In some aspects, dental drill guides can include a body defining an outer surface and an interior hole for receiving and positioning a dental drill; a first end of the body defining a tapered lead-in portion of the outer surface; a second end of the body opposite the first end defining at least one lip feature configured to be gripped by a handling tool; an outer circumferentially formed recess around the outer surface; and a seating feature extending from the outer surface.

Disclosed are example embodiments of a milling bur specifically designed to mill a dental prosthesis from a full-sintered zirconia blank. The milling bur comprises a milling tip configured to have a factor of safety of at least 2 by having a first coverage-percentage of grinding particles covering a surface area of the tip of the milling bur. The factor of safety is a number of time the milling bur can fully mill a dental prosthesis from a fully-sintered zirconia blank.

A system for performing a dental procedure includes a hand piece having a robot arm that extends along a first axis, and a medical tool coupled with a distal end of the robot arm. The system includes a first gimbal coupled with the robot arm for rotating the robot arm and the medical tool about the first axis, a second gimbal coupled with the robot arm for tilting the medical tool up and down relative to the first axis, and a third gimbal coupled with the robot arm for moving the medical tool up and down along a second axis that is perpendicular to the first axis. The hand piece includes a turret that supports the robot arm and rotates within a plane that is perpendicular to the second axis. The system has a first motor coupled with the first shaft for extending and retracting the first shaft along the first axis, a second motor coupled with the first shaft for rotating the first shaft around the first axis, a third motor coupled with the panning linkage for moving he first shaft to the left and the right within the plane that is perpendicular to the second axis, a fourth motor coupled with the second shaft for extending and retracting the second shaft along the first axis, and a fifth motor coupled with the third shaft for extending and retracting the third shaft along the first axis.
