Description

Manufacturing method of surgical guide element

The invention relates to a dental surgery guiding element and a method for manufacturing the same, in particular to a dental surgery guiding element and a method for assisting dental surgery by positioning a patient's teeth and defining an area to be operated on.

Current dental-related surgical procedures, such as but not limited to Lateral Window Sinus Lifting and Piezoelectic Alveolar Decortictin For Ortodontic Treatment, almost rely on performing surgery The doctor’s own expertise and experience determine the actual location, shape and scope of the actual knife during the operation. In the case of side window sinus augmentation, it is often used to open the bone plate on the side of the maxillary sinus before the implantation of the posterior tooth area, and the sinus mucosa is pulled up and filled with bone powder. After the thickness of the mandible increases, artificial dental implant procedures are performed. Piezoelectric Alveolar Cortical Bone Orthodontics is commonly used in the process of orthodontic treatment by cutting alveolar bone between teeth by applying alveolar decortical bone surgery. 1. Fine cutting path extending in the downward direction and applying high-speed micro-vibration to it with a piezoelectric vibrator can activate the alveolar bone cell remodeling ability, accelerate tooth movement and shorten the time required for tooth correction.

Although, before performing such dental-related surgical operations, three-dimensional (hereinafter referred to as 3D) images of the surgical target are obtained by, for example, X-ray photography or computer tomography (Computed Tomography; CT for short). For the doctor to evaluate the specific position, shape and range of the actual knife during the operation in advance. However, due to this type of X-ray photography or computed tomography, only clear 3D images of bones can be obtained, while other human soft tissues covering the bone surface, such as gums and gums, cannot obtain clear 3D images. Moreover, even if the soft tissue can be seen after the soft tissue flap is turned, it is often difficult to accurately locate the surgical cutting area due to the limitations and obstacles of the surrounding skin flap, resulting in the visual appearance of human tissue based on the professional and experience of the doctor. To guess or estimate the relationship between the underlying bone and the results of X-ray photography or computed tomography, it is impossible to accurately confirm the actual position, shape and range of the actual knife during surgery simply by the appearance of the human tissue. In addition, during the operation, the blood from the cutting of human soft tissue will flow or even cover the area of the operation, affecting the doctor's visual judgment, thereby reducing the accuracy of the doctor's control of the position, shape and range of the moving knife. In addition, if the doctor's own professional or inexperience is insufficient, it is more likely to miscalculate the position, shape or range of the moving knife during the operation, resulting in a reduction in the surgical effect, or even cause other sequelae or damage to the human body, such as The misalignment of the opening during the window sinus augmentation operation is too large to cause perforation of the sinuses or aggravate the degree of swelling and pain after surgery, or the tooth root is injured when the alveolar decortical bone correction surgery is performed, and the tooth is inactivated for no reason.

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

Step 21: Acquire at least one 3D image of a target object that the human body is scheduled to perform the operation. In this embodiment, the at least one 3D image includes: a bone 3D image of the target object and a tooth mold 3D image of the target object including soft tissue. Among them, the bone 3D image is obtained by computer tomography (CT) tomography. It exists in the form of a digital information file that can be interpreted and processed by the computer, such as but not limited to: the file extension is ".STL" digital information file. The 3D image of the dental mold is obtained by one of the following methods: scanning the inside of the oral cavity of the human body with an oral 3D scanner to obtain the 3D image of the dental mold; or, firstly using the impression material to print the traditional dental mold After a dental arch model is obtained by the method, a 3D scan is performed on the dental arch model with a 3D scanner to obtain a 3D image of the dental model. The 3D image of the dental model also exists in a form of digital information file that can be read and processed by the computer, such as but not limited to: a digital information file with the extension ".STL". Wherein, whether it is the 3D image of the dental model or the 3D image of the bone, the image of the plurality of teeth at the target object will also be 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 and a dental mold (including soft tissue) of the target object. In this embodiment, this step 22 further includes the following steps: step 221: determine a bone density range of the target; and step 222: reorganize the at least one 3D image of the target according to the bone density range.

Because each person's bone density (Bone Mineral Density or Bone Mass; BMD for short) is different, and different bone densities will affect the computer tomography image. For example, if the bone density value of the average person is converted into a computed tomography (CT) image, the CT value unit "Hounsfield Unit (HU)" used to represent the relative density in accordance with the general sprial CT specification is Between 60~300HU. Therefore, for bones with relatively low density (60~200HU) and bones with relatively high density (201~300HU), the sharpness of the image contours in the 3D images of bones obtained by computer tomography is There will be differences. On the contrary, if you use the professional dental CBCT (Cone-beam CT) tomography scanner, the image density range value will be different, and the unit of use will be different. Under the CBCT specification, the image intensity is used to determine the relative density of bones. Generally speaking, under the CBCT specification, the bone density value of normal people is between 300 and 2000; low-density bones The value is below 300, while the high-density bone value is above 2000. Therefore, in this embodiment, 3D image processing software such as Mimics Innovation Suite can be used to determine and select the appropriate bone density range value of the target object, and then according to the selected bone density range value The bone 3D image to ensure that the outline of the bone image displayed in the bone 3D image is clear and accurate.

In this embodiment, the reorganized 3D image is made by operating computer-aided 3D design software, such as but not limited to the aforementioned Mimics Innovation Suite, superimposing the dental model 3D image on the bone 3D image and making The image of at least one tooth included in the 3D image of the dental mold is aligned with the image of at least one tooth included in the 3D image of the bone. Therefore, the reconstituted 3D image of the present invention will include both the clear outlines of the target's bone (bone plate) and dental mold (including soft tissue), which can greatly improve the conventional technology and only use the bone 3D image to Assessing the location and extent of the surgery can easily lead to inaccurate surgery. In this embodiment, the reorganized 3D image also exists in the form of a digital information file with the extension ".STL".

Step 23: Design the shape and structure of the bite plate, positioning piece and at least one connecting frame of the guide element according to the reassembled 3D image obtained in step 22. Among them, the way of designing the guiding element is to operate the computer-aided 3D design software according to the appearance of the tooth and the dental model (soft tissue) displayed by the dental model 3D image in the reconstructed 3D image Contour to design the position, shape and range of the occlusal plate (including occlusal structure); and design the positioning piece according to the outline of the bone plate displayed by the bone 3D image in the reconstructed 3D image (Including the position of the body and the window), shape and range; in addition, according to the designed relative position and contour of the bite plate and the positioning piece, the design can connect the positioning piece to the bite plate, and It will not affect the sight line during the operation and the position, shape and range of the at least one connecting frame 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 in the form of 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 back 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 take into account the presence of gums and gums. Therefore, the outline of the teeth and dental mold (soft tissue) shown in the 3D image of the dental mold is used to design The position, shape and range of the bite plate can improve accuracy. The positioning piece is used to define the specific position, shape and range of the surgical knife, so the position, shape and range of the positioning piece (including the body and window) should use the bone shown in the 3D image of the bone The outline of the board can be designed to improve accuracy.

Step 24: Manufacture 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 the 3D printer, and the actual product of the guide element can be produced by 3D printing. In this embodiment, the material of the guiding element is a medical grade epoxy resin photocurable resin material. Using a 3D printer to gradually print out the shape of the guide element in a colloidal or liquid photocurable resin, and at the same time irradiate with a specific wavelength of light (such as but not limited to ultraviolet light) to cure the material, you can obtain The actual guide element conforming to the 3D design drawing of the guide element.

Step 25: Sterilize. Afterwards, the 3D printed guide element is sterilized and other subsequent treatments are used for the formal operation.

Please refer to FIGS. 4 and 5, which are respectively a perspective schematic view of a second embodiment of the dental surgery guide element of the present invention, and a schematic diagram of the second embodiment of the guide element when it is bitten by a human body (patient). In the second embodiment shown in FIGS. 4 and 5, the guide element is suitable for the construction of Piezoelectic Alveolar Decortictin For Ortodontic Treatment.

In the second embodiment, the guiding element 30 includes: an engaging plate 31, a positioning piece 32 and at least one connecting frame 33. The occlusal plate 31 can be used to occlude the upper and lower teeth 93 of the human body, so that the occlusal plate 31 is occluded and positioned between the upper and lower teeth 93. The upper and lower surfaces of the one-piece body 311 of the occlusal plate respectively have a plurality of occlusal structures 312, and the plurality of occlusal structures 312 correspond to the shapes and positions of the upper and lower teeth 93, respectively. The positioning piece 32 includes a piece 321 and at least one window 322 penetrating the piece. The at least one connecting frame 33 is connected between the bite 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 bite plate 31. In the second embodiment, the at least one window 322 includes a plurality of fine slots extending upward and downward, and the position, shape, and range of each fine slot are required for the correction of the alveolar decortical bone The position, shape and extent of cutting the human cortical bone. In addition, a plurality of through holes 323 are further provided on the sheet body 321 between the thin slots 322. Wherein, when the occlusal plate 31 is bitten and positioned between the upper and lower teeth 93 of the human body, the plate body 321 of the positioning plate 32 is adjacent to the gingival tissue surface of the human body, and the at least one window is opened The location, shape, and range of 322 are the location, shape, and range of cutting the human cortical bone and applying a piezoelectric vibrator to apply high-speed micro-vibration during the correction of the alveolar decortical bone. As for the shape and position of the at least one connecting frame 33, it is to avoid the dental braces installed on the upper and lower teeth 93, and it will not block the physician from cutting the cortical bone, and use the piezoelectric vibrator to apply The range of sight when high-speed micro-vibration is better With these fine slots (window 322), the physician can clearly, accurately and without hesitation know the specifics to be performed when cutting cortical bone and applying piezoelectric vibrators to apply high-speed micro-vibration Position, shape and range to avoid damage to adjacent roots due to execution errors. In addition, heat is generated when a piezoelectric vibrator is used to apply high-speed micro-vibration. Therefore, in general, when a high-speed micro-vibration is applied, water flow is applied to the operation area to cool down. In the present invention, by providing the through holes 323 between the thin slots (openings 322), the cooling water can smoothly flow into and out of the positioning plate 32, thereby improving the cooling effect. In this way, when the doctor performs piezoelectric alveolar decortical bone correction, the cortical bone can be cut and applied directly according to the position, shape and range of the window 322 (thin slot) of the positioning piece 32 The operation of high-speed micro-vibration eliminates the need to guess the position of bones or tooth roots covered under the soft tissue of the human body, and will not be affected by blood shielding, which can improve the accuracy of surgery and reduce the probability of sequelae or injury.
