Description

Technical Field

[0001] The present invention relates to the field of dental implant surgery, and in particular to a guide plate assembly, a design and manufacturing method and a system for immediate implantation in anterior teeth. Background Art

[0002] Among the options for restoring missing teeth, dental implants are becoming more and more popular. The implant placement accuracy directly affects the final position accuracy of the implant denture. In order to obtain the ideal restoration effect, an implant guide is needed to ensure the position, angle, and depth of the implant. Computer-aided design and manufacturing technology is used at home and abroad, that is, before the dental implant surgery, a three-dimensional model of the jaw is reconstructed through the patient's maxillofacial CT image, and the appropriate implant type is selected based on the image data of the jaw. Combined with the remaining teeth and bone mass of the jaw, a digital surgical guide is selected and designed to finally obtain an overall implant surgery plan. In this way, doctors can use surgical guides to perform safe and accurate implant surgery, which can not only prevent damage to the mandibular nerve and perforate the maxillary sinus floor, but also ensure that the implant is placed in the ideal position.

[0003] With the development of implant technology, immediate implantation has become a new demand. Immediate implantation means that dental implants can be placed immediately after tooth extraction. This method of dental implantation can shorten the time of tooth replacement, from preparation to successful implantation, and quickly and efficiently complete the implantation of a tooth, reducing the number of surgeries, preventing alveolar bone absorption and tooth loosening, protecting the natural morphology of gingival tissue, and improving the aesthetic effect. It has the following advantages: 1) There is no need to wait for the tooth extraction wound to heal, which shortens the treatment time; (2) During the healing process of traditional implantation for 3 months after tooth extraction, the alveolar bone is easily absorbed, especially the labial bone plate after the anterior teeth are extracted. Immediate implantation can effectively prevent alveolar ridge absorption, avoid disuse atrophy caused by tooth extraction, and minimize bone loss; (3) It can preserve soft tissue to a large extent, especially the preservation of gingival papillae, which can reduce the "black triangle (a triangle with the contact point of two teeth as the vertex and the gums as the base, mainly caused by gingival atrophy), increase beauty, and obtain the most soft tissue support, preserving the height and width of the alveolar bone.

[0004] The guide ring is a ring-shaped component on the implant guide. Its main function is to guide the precise implantation of the implant drill and limit the implantation site and implantation angle. However, in immediate implantation, since the drilling site is located in the fresh tooth extraction wound, the steep alveolar bone wall will produce lateral shear force on the drill needle, resulting in a deviation in the drilling direction. Since the guide ring is a closed structure, it cannot adapt to the lateral shear force that is inevitably generated during the immediate implantation process, which in turn affects the accuracy requirements of implant implantation. Summary of the invention

[0005] The purpose of the present invention is to provide a guide plate assembly, design and manufacturing method and system for immediate implantation in the anterior teeth area, so as to solve the problem that the prior art cannot adapt to the lateral shear force that is inevitably generated during the immediate implantation process, thereby affecting the accuracy requirements of implant placement.

[0006] A guide plate assembly for immediate implantation in the anterior teeth region, used for obtaining the three-dimensional position of the prepared implant when the anterior teeth aesthetic region is immediately implanted, characterized in that it comprises: a guide rail, a guide device and a drill assembly, wherein an arc track space is arranged in the guide rail, the guide device is arranged in the arc track space and the guide device can slide from a first lateral position to a second lateral target position in the track space, the sliding track is adapted to the immediate implantation value area of ​​the anterior teeth aesthetic region, and a longitudinal cavity is arranged in the guide device;

[0007] The setting of the guide rail, the guiding device and the drill bit assembly is configured as follows: the drill bit assembly can move axially in the longitudinal cavity, the stroke of the axial movement is adapted to the stroke of oblique drilling to the first positioning depth position, the guiding device slides in the arc track space to the second lateral target position to guide the drill bit assembly to perform arc cutting with the first positioning depth position as the center, and the drill bit assembly continues to cut toward the root to the cutting target depth position.

[0008] Preferably, the drill assembly includes a first drill, which includes a drill bit and a drill body. A protrusion is arranged on the drill body, and the protrusion can be clamped on the longitudinal cavity to limit the movement stroke of the cutting axis of the first drill. The axis movement stroke is adapted to the stroke of oblique drilling to a first positioning depth position, and during the arc cutting process performed by the first drill with the first positioning depth position as the center, the axial direction is consistent with the axial direction of the final implant.

[0009] Preferably, the drill needle assembly includes a second drill needle, which includes a drill bit and a drill body. A protrusion is provided on the drill body, and the protrusion can be clamped on the cavity to limit the cutting axial movement stroke of the second drill needle, and the stroke is consistent with the distance from the first positioning depth position to the cutting target depth position.

[0010] Preferably, the guiding device is a guide bead, and the diameter of the guide bead is tangent to the thickness of the guide rail.

[0011] Preferably, the arc-shaped track space of the guide rail includes at least a accommodating area for the guide beads to enter the space, a movable area and a target area, the accommodating area coincides with the first lateral position, and the target area cooperates with the shape of the guide beads to achieve limiting, which coincides with the second lateral target position.

[0012] Beneficial effects of the present invention:

[0013] 1) Improve the three-dimensional accuracy of implant placement in the anterior aesthetic area

[0014] 2) Ensure that physiological saline can be smoothly poured into the surgical area during the operation to protect the alveolar bone from high temperature damage caused by local cutting. Because the high-speed cutting drill will generate a lot of heat in a short period of time, it may cause irreversible damage to the alveolar bone and affect the subsequent bone integration process. Therefore, during the cutting process, equipment for pouring physiological saline must be equipped, and it must be ensured that the physiological saline can be stably poured onto the bone cutting surface to achieve a cooling effect. However, because traditional closed guide rings need to accurately limit the direction of the drill, it is difficult to have enough space for the placement of physiological saline pouring equipment. The guide rail design of the present invention leaves enough space for the pouring equipment to ensure that the temperature of the alveolar bone in the affected area is not too high during the cutting process.

[0015] 3) Reduce the obstruction of the guide ring to the surgeon's field of vision. The traditional closed guide ring needs to accurately limit the direction of the drill needle, so it is difficult for the surgeon to have enough space to look directly at the surgical area, which affects the surgeon's field of vision and may affect the accuracy of the surgery. The guide rail design of the present invention can improve the problem of the surgical area being completely blocked.

[0016] 4) Reduce the requirements for the patient's mouth opening, increase tolerance for insufficient mouth opening, and thus expand the indications for digital implant surgery. Currently, the indications for digital guide-guided implant surgery have strict restrictions on sufficient mouth opening, because too small an opening will hinder the operator's operation in the mouth. The present invention is designed as a linear open guide to adapt to the first cutting process, which is oblique cutting. It supports the drill to enter the mouth obliquely, and can be used for patients with smaller mouth openings, relax surgical requirements, and expand the clinical application scenarios of digital implants.

The embodiment provided in the drawings is a preferred example of a high-speed electrospark milling manufacturing method for a left atrial appendage occluder skeleton. However, the method can be implemented in many different forms and is not limited to the embodiments provided herein.

[0022] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle", "top", "side" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship is also regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0023] The core of the present invention is that the present invention improves the traditional closed ring guide ring structure, cancels the ring guide ring, and uses the guide rail and guide device of this invention in combination, which is used in the digital implant surgery for immediate implantation in the anterior teeth area. The guide device slides from the arc track space to the second lateral target position to determine the trajectory of lateral movement during cutting. The stroke of the oblique drilling axial movement is determined from the stroke of the oblique drilling to the first positioning depth position. The stroke of the axial depth is determined from the first positioning depth position to the cutting target depth position. The present invention uses a pre-planned three-dimensional precise cutting process, presets the design of the corresponding guide plate assembly, and then uses the manufactured guide plate assembly to achieve cutting during immediate implantation. It can not only fundamentally reduce the generation of lateral force by changing the drilling direction, but also assist in guiding the drill needle to prepare a local arc hole, avoiding the implantation deviation caused by the lateral force during immediate implantation, and realizing the accuracy and safety of digital implantation in the immediate implantation of the anterior teeth aesthetic area.

[0024] First embodiment

[0025] See also Figure 1 , which is an example diagram of a guide plate assembly for immediate implantation in the anterior teeth region. The guide plate assembly is used to obtain the three-dimensional position of the implant when preparing the implant for immediate implantation in the anterior teeth aesthetic region, and includes: a guide rail 10, a guide device 20 and a drill assembly 30.

[0026] An arc-shaped track space is set in the guide rail 10, and the guide device 20 is set in the arc-shaped track space. The guide device 20 can slide from the first lateral position A to the second lateral target position B in the track space. The sliding track is adapted to the immediate seed value area of ​​the anterior tooth aesthetic area. Figure 1 In the embodiment, the guide device 20 can use a guide bead as an example, and the arc track space is divided into a first positioning area 11 including a first lateral position A, a sliding area 12, and a second positioning area 13 including a second lateral target position B. The guide bead 20 is spherical and can be arranged in the first positioning area 11 first, and can enter the second positioning area 13 through the sliding area 12 under the action of external force. The guide bead can be made of a material with a certain elastic structure, or the inner periphery of the arc track space is made of an elastic structure. For example, the shape of the guide bead is similar to the first positioning area 11 and the second positioning area 13. The guide bead 20 is clamped on the first positioning area 11. Under the action of external force, it overcomes its clamping force and enters the sliding area 12, and then enters the second positioning area 13. There are many similar implementation structures, and this structure is only an example.

[0027] See also Figure 1 , a longitudinal cavity is provided in the guide device. For example, a longitudinal cavity 21 is provided in the guide bead 20. The drill assembly 30 can move axially in the longitudinal cavity 21. The guide rail 10, the guide device 20 and the drill assembly 30 are configured as follows (see Figure 2 ): The drill needle assembly 30 can move axially on the longitudinal cavity 21, and the stroke of the axial movement is adapted to the stroke of oblique drilling to the first positioning depth position O. The guide device 20 slides in the arc track space to the second lateral target position B to guide the drill needle assembly 30 to perform arc cutting with the first positioning depth position O as the center. The drill needle assembly 30 continues cutting toward the root to the cutting target depth position Q.

[0028] The first embodiment of the present invention is that the drill needle assembly includes a first drill needle 30, the first drill needle 30 includes a drill bit 31 and a drill body 32, a protrusion 321 is provided on the drill body 32, and the protrusion 321 can be clamped on the longitudinal cavity 21 to limit the stroke of the cutting axis movement of the first drill needle 30, and the axis movement stroke is adapted to the stroke of oblique drilling from point P to the first positioning depth position O, that is, the height design of the drill body part 322 of the drill body 32 that can pass through the longitudinal cavity 21 is adapted to the axis movement stroke (such as basically consistent). During the arc cutting process of the first drill needle 30 with the first positioning depth position O as the center, the axial direction is consistent with the final implant axial direction. The drill needle assembly includes a second drill needle (similar to the structure of the first drill needle), the second drill needle includes a drill bit and a drill body, and a protrusion is provided on the drill body, and the protrusion can be clamped on the cavity to limit the stroke of the cutting axial movement of the second drill needle, and the stroke is consistent with the distance from the first positioning depth position O to the cutting target depth position Q. In other words, the design position of the second drill bit protrusion is different from the design position of the first drill bit protrusion, and the height design of the drill body part of the second drill bit that can pass through the longitudinal cavity 21 is consistent with the distance from the first positioning depth position O to the cutting target depth position Q, that is, basically the same.

[0029] That is, this design includes three parts: guide rail, guide ball, and drill needle (I, II). Through the mutual restriction relationship between the three, the cutting process consisting of three steps is completed:

[0030] Process I: The guide bead enters the rail through the opening in the middle of the upper part of the rail and is located at the initial position A. The drill needle I (i.e. the first drill needle mentioned above) enters the guide bead and performs a downward cutting process perpendicular to the surface of the rail box until the protruding part of the drill needle I is restricted. In this process, the drill needle I moves from point P to point O. This cutting process is mainly used for positioning, and because of the oblique drilling design, it can reduce the deviation caused by lateral force.

[0031] Process II: According to the sliding of the guide bead inside the guide rail, the drill I is guided to perform arc cutting with point O as the center until the guide bead is located at the guide rail position B. At this time, the axial direction of the drill I should be consistent with the final implant axial direction. The purpose of this cutting process is to adjust the axial direction of the drill under the limitation of the guide rail.

[0032] Process III: The guide bead remains at position B, and the drill II (the second drill mentioned above) is replaced. The drill II continues to cut toward the root until the protruding part of the drill II is restricted. In this process, the drill II moves from point O to point Q at the root. The purpose of this cutting process is to further prepare the three-dimensional position of the implant.

[0033] See also Figure 3, which is an example diagram of a guide plate assembly for immediate implantation in the anterior teeth area. The drill needle assembly is a drill needle. For the convenience of distinction, the drill needle is called the third drill needle 40. The third drill needle 40 includes a first protrusion 41 and a second protrusion 42. The first protrusion 41 can be movably inserted into the drill body of the third drill needle 40. The first protrusion 41 realizes the function of the first drill needle, that is, the axial movement stroke is adapted to the stroke of oblique drilling from point P to the first positioning depth position O, that is, the height H1 of the drill body part that can pass through the longitudinal cavity 21 of the drill body is designed to be adapted to the axial movement stroke (such as basically consistent). During the arc cutting process of the third drill needle 40 with the first positioning depth position O as the center, the axial direction is consistent with the axial direction of the final implant. The function of the second protrusion 42 is similar to that of the second drill needle. The height H2 of the drill body part that can pass through the longitudinal cavity 21 of the second protrusion 42 is designed to be consistent with the distance from the first positioning depth position O to the cutting target depth position Q, that is, basically the same. The above structure completes the cutting process consisting of 3 steps:

[0034] Process I: The guide bead enters the rail through the opening in the middle of the upper part of the rail and is located at the initial position A. The third drill enters the guide bead and performs a downward cutting process perpendicular to the surface of the rail box until the protruding part 41 of the third drill is restricted. In this process, the third drill moves from point P to point O. This cutting process is mainly used for positioning, and because of the oblique drilling design, the deviation caused by the lateral force can be reduced.

[0035] Process II: According to the sliding of the guide bead inside the guide rail, the third drill is guided to perform arc cutting with point O as the center until the guide bead is located at guide rail position B. At this time, the axial direction of the third drill should be consistent with the final implant axial direction. The purpose of this cutting process is to adjust the axial direction of the drill under the limitation of the guide rail.

[0036] Process III: The guide bead remains at position B, and the first protrusion 41 is movably inserted into the drill body of the third drill 40. The third drill continues to cut toward the root until the second protrusion 42 of the third drill is restricted. In this process, the third drill moves from point O to point Q at the root. The purpose of this cutting process is to further prepare the three-dimensional position of the implant.

[0037] When the guiding device is a guide bead, the diameter of the guide bead can be tangent to the thickness of the guide rail. The arc track space of the guide rail at least includes the accommodation area, the activity area and the target area for the guide bead to enter the space (correspondingly, the first positioning area 11 including the first lateral position A, the sliding area 12 and the second positioning area 13 including the second lateral target position B), the accommodation area coincides with the first lateral position, and the target area cooperates with the shape of the guide bead to achieve limiting, which coincides with the second lateral target position.

[0038] To summarize: the local guide bead and the matching drill bit design: there is a cylindrical cavity in the middle of the guide bead, which can fit with the matching drill bit so that it can limit the direction of the drill bit; the diameter of the guide bead is exactly equal to the thickness and inner width of the box-shaped guide rail, so that it can slide inside the guide rail. The drill bit has one or more protrusions at the designed height to limit the cutting depth of the drill bit. The guide rail limits the guide bead, and the guide bead limits the drill bit. The above two restrictions can achieve: the entire arc cutting process of the drill bit is realized by the pre-designed guide rail.

[0039] Second embodiment

[0041] Scan the patient's oral cavity to obtain the patient's intraoral 3D model;

[0042] According to the intraoral three-dimensional model and at least the position where the implant needs to be implanted, a three-dimensional model of the bone cutting guide assembly is obtained, which further includes: determining a first transverse position, a second transverse target position, a first positioning depth position and a target depth position, designing the arc track space of the guide rail according to the first transverse position and the second transverse target position, and designing the longitudinal cavity of the guide device and the drill assembly;

[0044] In other words, an arc track space is set according to the first lateral position and the second lateral target position, thereby designing the guide rail. The position of the protrusion in the first drill is designed according to the first positioning depth position, and the position of the protrusion in the second drill is designed according to the first positioning depth position and the target depth position. That is, designing the drill assembly includes designing a first drill, the first drill includes a drill bit and a drill body, a protrusion position is set on the drill body, and the protrusion position can be clamped on the longitudinal cavity to limit the stroke of the cutting axis movement of the first drill, and the axis movement stroke is adapted to the stroke of the oblique drilling to the first positioning depth position, and during the arc cutting process of the first drill with the first positioning depth position as the center, the axial direction is consistent with the final implant axial direction. That is, designing the drill assembly includes designing a second drill, the second drill includes a drill bit and a drill body, a protrusion is set on the drill body, and the protrusion can be clamped on the cavity to limit the stroke of the cutting axial movement of the second drill, and the stroke is consistent with the distance from the first positioning depth position to the cutting target depth position.

[0045] When the third drill needle is used, the positions of the first protrusion and the second protrusion of the third drill needle are designed in the same manner.

[0046] Designing the guiding device further includes designing a guide bead, the diameter of the guide bead is tangent to the thickness of the guide rail, the arc track space of the guide rail at least includes a accommodating area, an active area and a target area for the guide bead to enter the space, the accommodating area coincides with the first lateral position, and the target area cooperates with the shape of the guide bead to achieve limiting, which coincides with the second lateral target position.
