Description

Dental surgery guiding element and its manufacturing method

The invention relates to a dental surgical guiding element and a manufacturing method thereof, in particular to a dental guiding element which can be positioned by a patient's teeth and defines an area to be operated to assist a dental operation and a manufacturing method thereof.

Currently dental-related surgery, such as, but not limited to, Lateral Window Sinus Lifting and Piezoelectic Alveolar Decortictin For Ortodontic Treatment, almost all rely on performing surgery The physician's own professional and experience to determine the specific location, shape and extent of the actual moving knife during surgery. In the case of lateral window sinus augmentation, it is often used to open the sinus mucosa upwards and fill the bone powder before the implant in the posterior region, by inserting the bone in the side of the upper sinus and filling it into the bone powder. After the thickness of the tibia is increased, the artificial dental implant procedure is performed. Piezoelectric coronal cortical orthopedic surgery, commonly used in the process of orthodontic treatment, by cutting the teeth being corrected with cochlear cortical osteotomy, cutting the alveolar bone between the teeth The fine cutting path extending in the downward direction and the high-speed micro-vibration applied by the piezoelectric vibrator can activate the alveolar bone cell remodeling ability, accelerate the tooth movement and shorten the time required for orthodontic treatment.

Although, before performing such dental-related surgery, a three-dimensional (hereinafter referred to as 3D) image of the surgical target body is obtained by, for example, X-ray photography or Computed Tomography (CT). For the physician to assess in advance the specific location, shape and extent of the actual moving knife during the operation. However, due to such X-ray radiography or computed tomography, only clear 3D images of the bones can be obtained, and for other human soft tissues covering the surface of the bone, such as gums, flesh, etc., clear 3D images cannot be obtained. Moreover, even if the hard tissue can be seen after the flap is soft tissue, it is often difficult to be accurate because of the limitations and obstacles of the surrounding flap. Determining the surgical cutting area, the doctor can only rely on his own professional and experience, from the visual appearance of the human tissue, to guess or estimate the relationship between the bones below and the X-ray or computed tomography results, can not be seen by visual alone The appearance of the human body tissue accurately confirms the specific position, shape and extent of the actual moving knife during surgery. In addition, during the operation, the blood flowing out of the soft tissue of the human body will flow or even obscure the surgical area, affecting the visual judgment of the physician, thereby reducing the accuracy of the doctor's control of the position, shape and range of the movable 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 discounted surgical effect or even other sequelae or injury to the human body, for example, on the executive side. When the window sinus is increased, the opening is misplaced or too large, which causes the sinus to perforate or aggravate the degree of swelling and pain after surgery, or the tooth root loss caused by the alveolar cortical orthopedic surgery. Therefore, there is still room for further improvement in existing dental-related surgical methods.

The bite plate 11 is adapted to engage the upper and lower teeth 93 of the human body such that the bite plate 11 is engaged and positioned between the upper and lower teeth 93. The upper and lower surfaces of the one-piece body 111 of the bite plate 11 respectively have a plurality of occlusal structures 112, and the plurality of occlusal structures 112 correspond to the shape and position of the upper and lower teeth 93, respectively. The positioning piece 12 includes a piece 121 and at least one opening window 122 extending through the piece 121.

Please refer to FIG. 3, which is a flow chart of an embodiment of a method for manufacturing a dental surgical guiding element of the present invention. The guiding element is a dental related surgical operation suitable for a human body, and the manufacturing method comprises 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. In the embodiment, the at least one 3D image includes: a bone 3D image of the target body, and a dental model 3D image of the target body including soft tissue. The bone 3D image is obtained by a computed tomography (CT) tomography scan, which is in the form of a digital information file that can be interpreted and processed by a computer, such as but not limited to: ".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, by using the impression material, the traditional dental impression mold After obtaining a dental arch model, the dental arch model was subjected to 3D scanning with a 3D scanner to obtain the dental model 3D image. The 3D image of the dental model is also in the form of a digital information file that can be interpreted and processed by the computer, for example, but not limited to: a digital information file with the name ".STL". Among them, the 3D image of the dental model or the 3D image of the skeleton also contains images of the plurality of teeth at the target.

Step 22: Recombining the at least one 3D image of the target to obtain a reconstructed 3D image showing a skeleton of one of the target and a tooth (including soft tissue). In this embodiment, the step 22 further includes the following steps: Step 221: determining a bone density range of the target body; and Step 222: Recombining 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) is different, different bone density will affect the image of computed tomography. For example, if the average human bone density value is converted into a CT value in a computed tomography (CT) image to indicate the relative density of the general sprial CT specification, the "Hounsfield Unit (HU)" is Between 60~300HU. Therefore, for bones with relatively low density (60~200HU) and bones with relatively high density (201~300HU), the image outline clarity of the bone 3D images obtained by computer tomography is There will be differences. In contrast, if the image density range of the CBCT (Cone-beam CT) tomograph using professional dental use is different, the unit of use will be different. Under the CBCT specification, the relative density of bones is determined by the input image intensity; in general, under the CBCT specification, the normal human bone density value 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, a 3D image processing software such as the Mimics Innovation Suite can be used to determine and select a suitable bone density range value of the target body, and then according to the selected bone density range value. The bone 3D image is used to ensure that the contour of the bone image displayed in the 3D image of the bone is clear and precise.

In this embodiment, the reconstructed 3D image is superimposed on the bone 3D image by operating a computer-aided 3D design software such as, but not limited to, the aforementioned Mimics Innovation Suite. The image of at least one of the teeth included in the 3D image of the dental model is obtained by aligning at least one image of the same tooth contained in the 3D image of the bone. Therefore, the reconstructed 3D image of the present invention will simultaneously contain a clear outline of both the bone (bone plate) and the dental mold (including soft tissue) of the target, which can greatly improve the conventional technique by simply using the bone 3D image. Assessing the location and extent of the procedure can lead to inaccurate surgical inadequacies. In this embodiment, the reconstructed 3D image is also in the form of a digital information file with the extension ".STL".

Step 23: Design the shape and structure of the bite plate, the positioning piece and the at least one connecting frame of the guiding element according to the reconstructed 3D image obtained in step 22. The method for designing the guiding component is to operate the computer-aided 3D design software according to the appearance of the tooth and the dental mold (soft tissue) displayed by the 3D image of the dental model in the reconstructed 3D image. Contouring to design the position, shape and extent of the bite plate (including the snap structure); and designing the contour of the bone plate displayed by the 3D image of the bone in the reconstructed 3D image The position, shape and range of the positioning piece (including the body and the window); and, according to the designed relative position and contour of the bite plate and the positioning piece, the positioning piece can be connected to the bite The plate, without affecting the position, shape and extent of the at least one connector of the line of sight and operation during surgery. After the design of the guiding component is completed, the 3D design of the guiding component 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 auxiliary name ".STL". In addition, it is also possible to test whether the 3D design of the guiding element is combined, superimposed on the 3D image of the bone, or the 3D image of the dental model to check whether the surgical position, shape and range defined by the guiding element are accurate. Since the bite plate is bitten by the teeth, the design of the contour must consider the presence of the gums and the flesh, so the shape of the teeth and the dental mold (soft tissue) displayed by the 3D image of the dental mold is used. The position, shape and extent 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 be the bones displayed by the bone 3D image. The contour of the board is designed to improve accuracy.

Step 24: The guiding element is manufactured in a 3D printing manner. After the design of the guiding element is completed, the digital information file of the guiding element can be input to the 3D printing machine, and the actual product of the guiding element can be produced by 3D printing. In the present embodiment, the material of the guiding member is a photocurable resin material using a medical grade epoxy resin. The colloidal or liquid photocurable resin is gradually printed out by the 3D printer to print out the shape of the guiding member while irradiating with a specific wavelength of light (for example, but not limited to ultraviolet light) to cure the material. The guiding element conforms to the 3D design of the guiding element.

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

Please refer to FIG. 4 and FIG. 5 , which are respectively a perspective view of a second embodiment of the dental surgical guiding element of the present invention, and a schematic view of the second embodiment of the guiding element being engaged by a human body (patient). In the second embodiment shown in Figures 4 and 5, the guiding element is a structure suitable for performing a Piezoelectic Alveolar Decortictin For Ortodontic Treatment.

In the second embodiment, the guiding element 30 comprises: a meshing plate 31, a positioning piece 32 and at least one connecting frame 33. The bite plate 31 is adapted to engage the upper and lower teeth 93 of the human body such that the bite plate 31 is engaged and positioned between the upper and lower teeth 93. a piece 311 of the bite plate The upper and lower surfaces respectively have a plurality of occlusal structures 312, and the plurality of occlusal structures 312 correspond to the shape and position of the upper and lower teeth 93, respectively. The positioning piece 32 includes a body 321 and at least one opening 322 extending through the 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 on the engaging plate 31 at a predetermined position. In the second embodiment, the at least one opening window 322 includes a plurality of fine slots extending in the upper and lower directions, and the position, shape and range of each of the thin slots are required for performing the coronal cortical orthopedic surgery. The position, shape and extent of the human cortical bone. In addition, a plurality of through holes 323 are defined in the sheet body 321 between the thin grooves 322. Wherein, when the bite plate 31 is bitten and positioned between the upper and lower teeth 93 of the human body, the body 321 of the positioning piece 32 is adjacent to the gingival tissue surface of the human body, and the at least one window is opened. The position, shape and extent of the 322 are the position, shape and extent of the high-speed micro-vibration that needs to be performed when the cochlear cortical orthopedic surgery is performed and the piezoelectric vibrator is applied. As for the shape and position of the at least one connecting frame 33, the orthodontic device installed on the upper and lower teeth 93 is avoided, and the doctor does not block the cortical bone, and the piezoelectric vibrator is applied. The line of sight at high speed and micro vibration is better. With these fine grooves (opening window 322), the doctor can clearly, accurately and without hesitation knowing the specifics to be performed when cutting the cortical bone and applying a high-speed micro-vibration using a piezoelectric vibrator. Position, shape and range to avoid damage to adjacent roots due to execution errors. Further, since heat is generated when a high-speed micro-vibration is applied by using a piezoelectric vibrator, a water flow is generally applied to the surgical field to cool down when high-speed micro-vibration is performed. In the present invention, by providing the through holes 323 between the thin slots (the window 322), the water flow for cooling can smoothly flow into and out of the positioning piece 32, thereby improving the cooling effect. Therefore, when the doctor performs the piezoelectric coronal cortical orthopedic surgery, the cortical bone can be cut and directly according to the position, shape and range of the opening window 322 (fine groove) of the positioning piece 32. The operation of high-speed micro-vibration does not need to guess the position of bone or root under the soft tissue of the human body, and it will not be affected by blood shielding, which can improve the accuracy of surgery and reduce the incidence of surgical sequelae or injury.

The above-mentioned embodiments are not intended to limit the scope of application of the present invention, and the scope of the present invention should be based on the technical spirit defined by the content of the patent application scope of the present invention and the scope thereof.
