Description

   Method for manufacturing surgical guide element   

The present invention relates to a dental surgery guiding element and a manufacturing method thereof, and more particularly, to a dental surgery guiding element and a manufacturing method thereof that can be positioned and defined by a patient's teeth in order to assist the surgery.

At present, dental-related surgical operations, such as but not limited to Lateral Window Sinus Lifting and Piezoelectic Alveolar Decortictin For Ortodontic Treatment, are almost always performed The physician's own expertise and experience determine the specific position, shape and range of the actual knife during the operation. For the side window sinus augmentation technique, it is often used before the posterior tooth implantation. It is used to open the hole in the bone plate on the side of the maxillary sinus and pull the sinus mucosa upward and fill it with bone powder. After the thickness of the sacrum increases, the artificial dental implant procedure is performed. Piezoelectric alveolar osteosynthesis is commonly used in the process of orthodontics, by applying alveolar decortical osteosynthesis to the teeth being corrected, cutting the alveolar bone between the teeth. The fine cutting path extending in the lower direction and applying a high-speed micro-vibration to it with a piezoelectric vibrator can activate the alveolar bone cell remodeling ability, accelerate the tooth movement and shorten the time required for orthodontics.

Although before performing such dental-related surgical operations, three-dimensional (hereinafter referred to as 3D) images of surgical targets are obtained by means of, for example, X-ray photography or computerized tomography (CT). For the physician to evaluate the specific position, shape and range of the actual moving knife before surgery. However, as a result of such X-ray photography or computer tomography, only clear 3D images of bones can be obtained, while other soft tissues such as gums and plaques covering the surface of bones cannot obtain clear 3D images. In addition, even if hard tissue can be seen after performing soft tissue flaps, it is often difficult to accurately locate the surgical cutting area due to the limitations and obstructions of the surrounding flaps, resulting in the physician's visual appearance of human tissue based on his own professional and experience. To guess or estimate the relationship between the underlying bones and the results of X-ray photography or computer tomography, it is impossible to accurately confirm the specific position, shape and range of the actual moving knife during surgery based on the appearance of human tissue alone. In addition, during the surgery, the blood flowing out of the cut human soft tissue will flow or even cover the area of the operation, which affects the physician's visual judgment, thereby reducing the accuracy of the physician's control of the position, shape and range of the moving knife. In addition, if the physician's own expertise or experience is insufficient, the position, shape, or range of the moving knife may be miscalculated during the operation, which may result in a reduction in the surgical effect and even cause other sequelae or injuries to the human body, such as on the side of the executive side. The misalignment of the openings during the window sinus augmentation surgery may cause the perforation of sinuses or increase the degree of swelling and pain after sinus perforation, or damage to the root of the teeth during alveolar decortical orthodontic surgery, which may result in ineffective tooth loss. Therefore, there is still room for improvement in the existing dental-related surgical methods.

Please refer to FIG. 3, which is a flowchart of an embodiment of a method for manufacturing a dental surgery guide element according to the present invention. The guide element is suitable for a dental operation related to a human body. The manufacturing method includes the following steps:

Step 21: Obtain at least one 3D image of the target that the human body is scheduled to perform the surgical operation on. In this embodiment, the at least one 3D image includes: a 3D image of a bone of the target and a 3D image of a dental mold containing the soft tissue of the target. The 3D image of the bone is obtained by means of tomographic scanning by a computer tomography scanner (CT). It exists as a digital information file that can be interpreted and processed by a computer, such as, but not limited to, an extension named ".STL" digital information file. The dental mold 3D image is obtained by one of the following methods: scanning the inside of the human's oral cavity with an oral 3D scanner to obtain the dental mold 3D image; After obtaining a dental arch model in the same manner, 3D scanning is performed on the dental arch model with a 3D scanner to obtain a 3D image of the dental mold. The dental mold 3D image also exists in a type of digital information file that can be read and processed by a computer, such as, but not limited to, a digital information file with an extension ".STL". Wherein, whether it is the 3D image of the dental mold or the 3D image of the bone, the image of the plurality of teeth at the target object is also included.

Step 22: Reorganize the at least one 3D image of the target object to obtain a reconstructed 3D image that can show the outline of a bone of a target object and a dental mold (including soft tissue). In this embodiment, this step 22 further includes the following steps: step 221: determine a bone density range of the target object; and step 222: reconstruct the at least one 3D image of the target object according to the bone density range.

Because each person's bone density (Bone Mineral Density or Bone Mass; BMD for short) is different, different bone density will affect the image of computer tomography. For example, if the bone density value of an ordinary person is converted into a CT value unit in a computer tomography (CT) image used to represent the relative density in accordance with the general spritical CT specification, the "Hounsfield Unit (HU)" is Between 60 ~ 300HU. Therefore, for bones with relatively low density (60 to 200 HU) and bones with relatively high density (201 to 300 HU), the sharpness of the image contours in the bone 3D image obtained by computer tomography is There will be differences. In contrast, if a CBCT (Cone-beam CT) tomography scanner is used, the image density range values will be different, and the units used will be different. Under the CBCT standard, the relative density of bones is determined by the input image intensity; generally, under the CBCT standard, the bone density value of normal people is between 300 and 2000; low density bones The value is 300 or less, while the high-density bone value is 2000 or more. Therefore, in this embodiment, 3D image processing software such as Mimics Innovation Suite can be used to determine and select a suitable bone density range value for the target, and then according to the selected bone density range value corresponding to The bone 3D image ensures that the outline of the bone image displayed in the bone 3D image is clear and accurate.

In this embodiment, the reconstructed 3D image is obtained by operating computer-aided 3D design software, such as but not limited to the aforementioned Mimics Innovation Suite, superimposing the dental mold 3D image on the bone 3D image and An image of at least one tooth included in the 3D image of the dental mold is obtained by aligning an image of at least one identical tooth included in the 3D image of the bone. Therefore, the recombined 3D image of the present invention will contain both the clear contours of the target's bones (bone plates) and dental molds (including soft tissues), which can greatly improve the conventional technology by using only bone 3D images. Assessing the location and scope of the surgery can lead to inaccurate misses. In this embodiment, the reconstructed 3D image also exists as a digital information file with the extension ".STL".

Step 23: According to the reconstructed 3D image obtained in step 22, design the shape and structure of the bite plate, the positioning piece, and the at least one connecting frame of the guide element. Wherein, the way of designing the guide element is to operate the computer-aided 3D design software, according to the shape of the teeth and the dental mold (soft tissue) displayed by the dental mold 3D image in the reconstructed 3D image. Outline, to design the position, shape, and range of the occlusal plate (including the occlusal structure); and to design the positioning piece according to the outline of the bone plate shown by the bone 3D image in the reconstructed 3D image (Including the sheet body and the window) the position, shape, and range; in addition, according to the designed relative position and contour of the bite plate and the positioning piece, designing that the bite can be connected to the bite plate, and It will not affect the position, shape and range of the at least one connecting bracket during the sight and operation during the operation. After the design of the guide element is completed, the 3D design drawing of the guide element can be output and stored as a digital information file, such as, but not limited to, a digital information file with the extension ".STL". In addition, you can also try to combine the 3D design drawings of the guide element, superimpose it on the 3D image of the bone, or the 3D image of the dental mold to check whether the surgical position, shape and range defined by the guide element accurate. Since the occlusal plate is bitten by teeth, the design of its outline must consider the presence of gums and flesh. Therefore, the outline of the teeth and the mold (soft tissue) shown on the 3D image of the dental mold is used to design The position, shape and range of the bite plate can improve accuracy. Because the positioning piece is used to define the specific position, shape, and range of the surgical knife, the position, shape, and range of the positioning piece (including the body and the window) should use the bone shown in the 3D image of the bone. The contour of the board is designed to improve the accuracy.

Step 24: manufacturing the guide element by 3D printing. After the design of the guide element is completed, the digital information file of the guide element can be input to a 3D printer, and the actual product of the guide element can be produced by 3D printing. In this embodiment, the material of the guide element is a medical-grade epoxy-based photo-curable resin material. A 3D printer can be used to gradually print the shape of the light-curing resin in the form of a gel or liquid, and at the same time irradiate the material with a specific wavelength of light (such as but not limited to ultraviolet light) to cure the material. The actual guiding element conforms to the 3D design drawing of the guiding element.

Step 25: Disinfection. After that, the actual 3D printed guide element is sterilized and other subsequent processed for use in the formal operation.

The positioning sheet 32 includes a sheet body 321 and at least one opening window 322 passing through the sheet body. The at least one connecting frame 33 is connected between the engaging plate 31 and the positioning piece 32, so that the positioning piece 32 can be supported by the at least one connecting frame 33 and held at a predetermined position on the engaging plate 31. In the second embodiment, the at least one window 322 includes a plurality of fine slots extending in the upper and lower directions. The position, shape, and range of each of the fine slots are required to perform the alveolar decortical surgery. The position, shape, and extent of cutting the human cortical bone. In addition, a plurality of through-holes 323 are further formed in the sheet body 321 between the fine slots 322. Wherein, when the bite plate 31 is bitten and positioned between the upper and lower teeth 93 of the human body, the sheet body 321 of the positioning piece 32 is adjacent to the surface of the gum tissue of the human body, and the at least one window is opened The position, shape, and range of 322 are the positions, shapes, and ranges of cutting the human cortical bone and applying a high-speed micro-vibration using a piezoelectric vibrator during the alveolar decortical bone correction. As for the shape and position of the at least one connecting frame 33, it is to avoid the orthodontics installed on the upper and lower teeth 93, and not to block the doctor from cutting the cortical bone, and using a piezoelectric vibrator to apply The line of sight during high-speed micro-vibration is better. With these fine slots (windows 322), doctors can be clear, precise, and hesitant to know the specifics to be performed when cutting cortical bone and applying high-speed micro-vibrations using a piezoelectric vibrator. Position, shape, and extent to avoid damage to adjacent roots due to execution errors. In addition, since a high-speed micro-vibration is generated by using a piezoelectric vibrator, heat is generated. Therefore, when a high-speed micro-vibration is performed, a water flow is generally applied to the operating area to cool down. In the present invention, the through-holes 323 are provided between the fine slots (windows 322), so that the cooling water flow can smoothly flow into and out of the positioning piece 32, and the cooling effect is improved.
