Abstract

A method for reducing angulation error during the placement of dental implants or other dental procedures. Two or more sensors are used to monitor realtime orientation of a dental handpiece. One or more signal emitters are used in order to notify the user that a first orientation of the dental handpiece has been identified and recorded. One or more signal emitters are used to notify the user that the dental handpiece has been repositioned into a second orientation having a predetermined spatial relationship to the first orientation.

First claim

What is claimed is:

1. A method for reducing angulation error during dental procedures, the method comprising:
providing a device for reducing angulation error during dental procedures, the device comprising:
two or more than two, sensors that monitor realtime orientation of the device in space;
a programmable computer processor comprising both an input channel and an output channel connected to the two or more than two sensors;
a computer-sensor interface for connecting to a computer for programming the device and for receiving and manipulating data from the device, the computer-sensor interface connected to the programmable computer processor;
one or more than one signal emitter connected to the computer-sensor interface through the output channel for emitting one or more than one signal; and
an actuator connected to the programmable computer processor by way of the input channel,

actuating the device to identify and record a first orientation comprising three axial planes (X, Y and Z), where the one or more than one signal emitters of the device emits one or more than one signal to confirm that the device has identified and recorded the first orientation; and
repositioning the device to a second orientation comprising three axial planes (X, Y and Z) and having a predetermined spatial relationship to the three axial planes (X, Y and Z) of the first orientation;
where the one or more than one signal emitted confirming that the device has identified and recorded the first orientation is selected from the group consisting of an audible signal, a visible signal and both an audible and a visible signal.

2. The method of claim 1 , further comprising identifying a patient with a loss of a tooth or teeth requiring one or more than one dental implant.

3. The method of claim 1 , further comprising providing a dental handpiece, and attaching the device to the dental handpiece to create a system.

4. The method of claim 3 , where the dental handpiece comprises a dental drill.

5. The method of claim 4 , further comprising using the dental handpiece of the system to create a first osteotomy for a first implant in the mandible or maxilla of the patient without using a hole guide.

6. The method of claim 5 , further comprising using the dental handpiece of the system to create a second osteotomy without using a hole guide.

7. The method of claim 1 , where the device provided is part of a system comprising a dental handpiece.

8. The method of claim 7 , where the dental handpiece comprises a dental drill.

9. The method of claim 8 , further comprising using the dental handpiece of the system to create a first osteotomy for a first implant in the mandible or maxilla of the patient without using a hole guide.

10. The method of claim 9 , further comprising using the dental handpiece of the system to create a second osteotomy without using a hole guide.

11. The method of claim 1 , where the first orientation is recorded for an osteotomy.

12. The method of claim 1 , where the first orientation is recorded for a structure selected from the group consisting of an existing implant, a paralleling pin, a root socket, a template and a tooth.

13. The method of claim 1 , where the second orientation is a site of an implant in the mandible or maxilla of a patient.

14. The method of claim 1 , where the three axial planes of the second orientation and the three axial planes of the first orientation have a predetermined spatial relationship in which one or more than one axis plane of the second orientation is parallel to the corresponding one or more than one axis plane of the first orientation.

15. The method of claim 1 , where the three axial planes of the second orientation and the three axial planes of the first orientation have a predetermined spatial relationship in which each of the three axial planes of the second orientation are not parallel to the corresponding three axial planes of the first orientation.

16. The method of claim 1 , where the device emits one or more than one signal to confirm that the device is at the second orientation, and the method further comprises repositioning the device until the device emits one or more than one signal, thereby indicating that the device is at the second orientation, where the one or more than one signal emitted when the device is at the second orientation is selected from the group consisting of an audible signal, a visible signal and both an audible and a visible signal.

17. The method of claim 1 , where the device emits one or more than one signal to confirm that the device is not at the second orientation, and the method further comprises repositioning the device until the device ceases to emit one or more than one signal, thereby indicating that the device is at the second orientation, where the one or more than one signal emitted when the device is not at the second orientation is selected from the group consisting of an audible signal, a visible signal and both an audible and a visible signal.

18. The method of claim 1 , where one of the sensors of the device is a magnetometer, and where the method further comprises deactivating the magnetometer before identifying and recording the first orientation.

19. The method of claim 1 , where one of the sensors of the device is a gyroscope.

20. The method of claim 1 , where two of the three axial planes of the second orientation are within a predetermined deviation of the corresponding two axial planes in the three axial planes of the first orientation.

21. The method of claim 1 , where all three axial planes of the second orientation are within a predetermined deviation of their corresponding three axial planes of the first orientation.

22. The method of claim 1 , where the device is capable of switching between emitting one or more than one signal to confirm that the device is at the second orientation or emitting one or more than one signal to alert that the device is not at the second orientation, where the one or more than one signal being emitted is selected from the group consisting of an audible signal, a visible signal, and both an audible and a visible signal.

23. The method of claim 1 , where the device further comprises:
a digital display that shows the predetermined spatial relationship between the first orientation and the second orientation; and
control buttons that allow the user to set the predetermined spatial relationship between the first orientation and the second orientation.
