Abstract: A drill guide employs multiple layers of materials with different mechanical properties in order to achieve concurrent goals of rigidity, fit and retention. For example, a rigid exterior shell and a soft interior may be used together to securely and precisely fit a drill guide to a surgical site.

Abstract: A drill guide uses a hole in a layer to guide a drill along an axial trajectory while permitting off-axis excursions of the drill during use. A number of such drill guides at varying heights from a target surface may be used sequentially or concurrently to enforce the axial trajectory in three dimensions during a surgical operation. A drill guide may include a hole in a layer that establishes a single point along the axial trajectory, or the drill guide may include multiple layers in a single device to establish two or more points along the trajectory while allowing off-axis insertion of a drill into the guide. The drill guide may be cuttable to accommodate intraoperative changes to the axial trajectory. In embodiments, a window or the like may be provided to permit a surgeon to view drill depth, drill orientation, the surgical site and the like during a procedure.

Abstract: A digital model of a dental implant site can be modified to impart various features aligned to a trajectory for a planned drilling procedure. An object fabricated from the modified model can then be used as a mold to vacuum form or otherwise fabricate a drill guide for the drilling procedure. Numerous variations are possible to fabricate on-surface and off-surface guides, and/or thin layer guides or tube guides suitable for use in dental surgery.

Abstract: A series of drills are provided for creating progressively larger and/or deeper holes in a dental implant procedure based upon a single drill guide. In one embodiment, the drills are monolithic or single-piece drills. In another embodiment, drills are held in drill extensions that provide control of depth independent of drill length. Using the techniques described herein, a kit of drills and/or extensions may be provided for independent control of hole depth and hole diameter during a progressive drilling procedure.
