Abstract

A method for forming a surgical guide for a dental patient rotates material about a rotation axis to a first angular position and drills a drill guiding hole using a drilling tool having a drilling tool axis. The drill guiding hole is centered about a guide axis that is orthogonal to the rotation axis. A first planar surface of the guide is formed from the material, wherein the first surface is. oblique to the guide axis. The material is repositioned to orient the first surface orthogonal to the drilling tool. A hole pattern is formed having two or more positioning holes in the first surface, with the pattern corresponding to a pin pattern in a tray that is positionally registered to a dental arch of the patient. A second planar surface of the surgical guide is formed, parallel to the first planar surface.

First claim

The invention claimed is:

1. A method for forming a surgical guide for drilling of a dental patient, comprising:
mounting a block of machinable material having a prescribed shape to a holder;
rotating the block of machinable material by the holder about a rotation axis to a first angular position;
drilling a drill guiding hole through the block of machinable material using a drilling tool having a drilling tool axis that is orthogonal to the rotation axis, wherein the drill guiding hole is centered about a guide axis that is substantially orthogonal to the rotation axis;
repositioning the block of machinable material by the holder and forming a first planar surface of the surgical guide from the block of machinable material using the drilling tool, wherein the first planar surface is oblique to the guide axis;
repositioning the block of machinable material to orient the first planar surface orthogonal to the drilling tool axis;
forming a hole pattern having two or more positioning holes in the first planar surface using the drilling tool, wherein the hole pattern corresponds to a pin pattern in a tray that is positionally registered to a dental arch of the patient; and
repositioning the block of machinable material by the holder and forming a second planar surface of the surgical guide from the block of machinable material using the drilling tool to complete the surgical guide, wherein the second planar surface is parallel to the first planar surface,
where the holder is configured to move the block of machinable material with respect to the drilling tool when forming the surgical guide only along each of orthogonal axes X, Y, and Z, and where the rotation axis is the X-axis, and where the rotation of the holder with respect to the drilling tool is only around the X axis.

2. The method of claim 1 wherein forming the first planar surface comprises milling the surface from the material using a lateral surface of the drilling tool.

3. The method of claim 2 wherein the first planar surface is oblique with respect to the orthogonal X, Y, and Z axes of a 4-axis milling machine.

4. The method of claim 1 wherein the tray is positionally registered to the dental arch of the patient using an impression forming material.

5. The method of claim 1 wherein the surgical guide is formed of metal.

6. The method of claim 1 wherein the surgical guide is formed of plastic.

7. The method of claim 1 further comprising obtaining information about the patient from a volume image and following an implant plan generated according to the obtained information.

8. The method of claim 1 further comprising mounting the surgical guide onto the tray by matching the hole and pin patterns.

9. The method of claim 8 further comprising drilling into a jaw bone of the patient through the drill guiding hole.

10. A method for forming a surgical guide for drilling of a dental patient, comprising:
rotating a metal material block about a rotation axis to a first angular position;
drilling a drill guiding hole through the metal material block using a drilling tool that has a drilling tool axis that is orthogonal to the rotation axis, wherein the drill guiding hole is centered about a drill guide axis that is substantially orthogonal to the rotation axis;
milling a first planar surface of the surgical guide from the metal material block, wherein the first planar surface is oblique to the drill guide axis, where milling the first planar surface comprises milling the surface from the material using a lateral surface of the drilling tool;
repositioning the metal material block to orient the first planar surface orthogonal to the drilling tool axis;
drilling a hole pattern having two or more positioning holes in the first planar surface using the drilling tool, wherein the hole pattern corresponds to a pin pattern in a tray that is positionally registered to a dental arch of the patient according to an impression obtained from the patient; and
milling a second planar surface of the surgical guide to complete the surgical guide, wherein the second planar surface is parallel to the first planar surface.

11. The method of claim 10 , where the milling is done using a 4-axis milling machine that comprises the drilling tool and a holder, where the material is mounted to the holder of the 4-axis milling machine, where the 4-axis milling machine is configured to move the material with respect to the drilling tool along each of orthogonal axes X, Y, and Z, and where the rotation axis is only the X-axis.
