## Abstract

A dental operation-guiding structure includes a bite plate, a marking plate, and at least one connection frame connecting the bite plate and the marking plate. The bite plate is occluded by lower and upper teeth of a human body. The marking plate includes a plate body and at least one window penetrating the plate body. The plate body is adjacent to a tissue surface, and the windows defines a position to be operated. By occluding the dental operation-guiding structure, practical positions, patterns and ranges for the operation can be easily defined. The method for producing the dental operation-guiding structure overlaps a 3D bone image of a target object onto a 3D teeth-mold image thereof to obtain a reconstructed 3D image including clear contours of bones and soft tissues, bases on the reconstructed 3D image to design the dental operation-guiding structure, and finally produces the dental operation-guiding structure by 3D printing.

## Claims

### Claim 1

A dental operation-guiding structure, applied to a dental-related operation upon a human body, comprising:
a bite plate, capable of being adapted to be occluded and thus positioned between lower and upper teeth of the human body;
a marking plate, including a plate body and at least one window penetrating the plate body; and
at least one connection frame, connecting the bite plate and the marking plate;
wherein, when the bite plate is adapted to be occluded and thus positioned between the lower and upper teeth, the plate body of the marking plate is configured for placement adjacent to a tissue surface of the human body, and the at least one window defines corresponding at least one area to be operated;
wherein, the plate body further has a plurality of through holes distributed near to the at least one window; said through holes are used to flow a cooling water there-through in order to improve a heat-dissipation performance of the dental operation-guiding structure during the dental-related operation;
wherein the bite plate has an upper surface and a lower surface opposing to the upper surface, and each of the upper and lower surfaces has thereon a plurality of bite structures individually formed respective to corresponding patterns and positions of the lower and upper teeth;
wherein, while the dental operation-guiding structure is applied to an alveolar orthopedic surgery, the at least one window includes a plurality of slots extending approximately a vertical direction, and each of the plurality of slots defines a position, a pattern and a range of a cut configured for cutting on a cortical bone of the human body; wherein the through holes are distributed among the plurality of slots for allowing said cooling water to flow through the through holes in order to improve the heat-dissipation performance of the dental operation-guiding structure during the alveolar orthopedic surgery;
wherein, the alveolar orthopedic surgery is operated by using a piezoelectric vibrator; the bite plate is adapted to be occluded by the lower and upper teeth of the human body, such that the upper and lower teeth are in an occluded state during the alveolar orthopedic surgery; all of the slots and the through holes are adapted to be exposed on a front surface of a gum tissue of the human body, in addition, there is at least one said through hole being located between any two neighboring said slots.

### Claim 2 (depends on 1)

The dental operation-guiding structure of claim 1, wherein the dental operation-guiding structure is produced by 3D printing, and patterns and ranges of the at least one window define corresponding patterns and ranges of areas to be operated.

### Claim 3 (depends on 1)

The dental operation-guiding structure of claim 1, wherein, at least one dental brace is capable of being adapted to be mounted on at least one of the lower and upper teeth; and the at least one connection frame detours around the at least one dental brace.
