Abstract

A method of making a custom dental clamp, the method comprising producing a first clamp member using data from a scan of a patient's tooth, the first clamp member having at least one surface shaped to conform to a first surface of the tooth, producing a second clamp member using data from the scan, the scan clamp member having at least one surface shaped to conform to a second surface of the tooth, and connecting the first clamp member to the second clamp member with a resilient member.

First claim

What is claimed:

1 . A method of making a custom dental clamp, the method comprising:
producing a first clamp member using data from a scan of a patient's tooth, the first clamp member having at least one surface shaped to conform to a first surface of the tooth; producing a second clamp member using data from the scan, the scan clamp member having at least one surface shaped to conform to a second surface of the tooth; and connecting the first clamp member to the second clamp member with a resilient member.

2 . The method of claim 1 wherein producing the first clamp member and the second clamp member comprises 3D printing the first clamp member and the second clamp member.

3 . The method of claim 1 wherein connecting the first clamp member to the second clamp member comprises producing the resilient member integrally with the first clamp member and the second clamp member.

4 . The method of claim 1 , further comprising producing a port on at least one of the first clamp member, the second clamp member, and the resilient member, wherein the port is in fluid communication with an aperture in the first clamp member.

5 . The method of claim 1 , further comprising coupling a light source to at least one of the first clamp member, the second claim member, and the resilient member.

6 . The method of claim 1 , further comprising coupling a camera to at least one of the first clamp member, the second clamp member, and the resilient member.

7 . The method of claim 1 wherein producing the first clamp member comprises producing the first clamp member from a material selected from a group consisting of acrylonitrile butadiene styrene, nylon, high-density polyethylene, polyethylene terephthalate, or polyethylene terephthalate glycol.

8 . The method of claim 1 wherein connecting the first clamp member to the second clamp member comprises producing an arc shaped resilient member integral with the first clamp member and the second clamp member.

9 . The method of claim 1 wherein producing the first clamp member using data from the scan of the patient's tooth comprises producing the first clamp member using a 3D image of the tooth generated from the scan.

10 . A dental clamp comprising:
a first clamp member having at least one surface shaped to conform to a first surface of a tooth; a second clamp member having at least one surface shaped to conform to a second surface of the tooth; a resilient member connecting the first clamp member to the second clamp member.

11 . The dental clamp of claim 11 further comprising a port in fluid communication with an aperture in the first clamp member.

12 . The dental clamp of claim 12 further comprising a port in fluid communication with an aperture in the resilient member.

13 . The dental clamp of claim 11 wherein the first clamp member, the second clamp member, and the resilient member are integral with each other.

14 . The dental clamp of claim 11 further comprising a camera coupled to at least one of the first clamp member, the second clamp member, and the resilient member.

15 . The dental clamp of claim 11 further comprising at least one light source coupled to at least one of the first clamp member, the second clamp member, and the resilient member.

16 . The dental clamp of claim 11 wherein the at least one surface of the first clamp member and the at least one surface of the second clamp member face each other.

17 . The dental clamp of claim 11 wherein the first clamp member and the second clamp member comprise a material selected from a group consisting of acrylonitrile butadiene styrene, nylon, high-density polyethylene, polyethylene terephthalate, or polyethylene terephthalate glycol.

18 . The dental clamp of claim 11 wherein the resilient member is substantially arc shaped.

19 . The dental clamp of claim 11 wherein the first clamp member has a second surface substantially normal to the at least one surface and wherein the second surface includes an aperture.

20 . A rubber dam clamp comprising:
a custom 3D printed body having an internal channel; a barbed connector, wherein the barbed connector is connected to at least one opening in the body by the internal channel.

21 . The rubber dam clamp of claim 21 further comprising an LED light source.

22 . The rubber dam clamp of claim 21 further comprising a digital camera.
