In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0025] like Figure 1 As shown, this embodiment of the invention provides an implant guide plate, including a guide plate base 1, a saliva suction mechanism, and a lip blocking mechanism. The guide plate base 1 has an implant hole 2 that penetrates through the guide plate base 1. The guide plate base 1 is fabricated based on a three-dimensional model of the patient's teeth, and the implant hole 2 is positioned corresponding to the implant placement location.

[0026] The saliva suction mechanism includes a saliva suction cavity 3 and a guide tube 4. The saliva suction cavity 3 is located on the guide plate base 1 near the implantation hole 2. Multiple saliva suction holes 301 are provided on the outer wall of the saliva suction cavity 3, each of which is connected to the saliva suction cavity 3. That is, during the implantation procedure, blood and saliva from the patient's mouth, as well as the cooling fluid sprayed from the implantation handpiece, can enter the saliva suction cavity 1 through the saliva suction holes 301. One end of the guide tube 4 is connected to the saliva suction cavity 3, and the other end of the guide tube 4 is used to connect to a negative pressure suction device (not shown in the figure).

[0027] The lip shielding mechanism includes a lip baffle 6, which is positioned on the guide plate base 1 below the implantation hole 2. By setting the lip baffle 6, the implantation handpiece can be effectively prevented from colliding with the patient's lip when it is moved to the implantation position, thus ensuring the smooth progress of the implantation procedure.

[0028] The lip baffle 6 includes a baffle body 601 and arc-shaped folded edges 602 disposed on the left and right sides of the baffle body 601. The upper end of the baffle body 601 is connected to the guide plate base 1. The two arc-shaped folded edges 602 are disposed opposite to each other, and each arc-shaped folded edge 602 is connected to the baffle body 601 by a circular arc transition, thereby forming a downwardly recessed groove structure between the baffle body 601 and the two arc-shaped folded edges 602, so that during the implantation operation, the blood, saliva and coolant in the patient's mouth can flow into the groove of the baffle body 601.

[0029] In this embodiment of the invention, the implantation guide plate, during the implantation operation, activates the negative pressure suction device. Under the suction force of the negative pressure suction device, the blood, saliva, and cooling fluid in the patient's mouth can be drawn into the suction cavity 1 through the suction hole 301. The liquid in the suction cavity 3 is then promptly discharged through the guide tube 4, effectively preventing the patient from choking on the blood, saliva, and cooling fluid in the patient's mouth, thus improving the safety of the implantation operation.

[0030] In some embodiments of the present invention, a baffle plate 603 is provided on the baffle body 601 at a position away from the guide plate base 1, and the two ends of the baffle plate 603 are respectively connected to the inner sidewalls of the two arc-shaped folded edges 602. That is, by providing the baffle plate 603, the liquid flowing into the groove of the baffle body 601 can be blocked, preventing the liquid from flowing downward from the baffle body 601.

[0031] The baffle body 601 is further provided with a liquid suction chamber 604, which is located on the side of the baffle 603 facing the guide plate base 1. The outer wall of the liquid suction chamber 604 is provided with multiple liquid suction holes 605, each of which is connected to the liquid suction chamber 604. The liquid suction chamber 604 is connected to the guide pipe 4 through the connecting pipe 7. That is, under the suction of the negative pressure suction device, the liquid in the groove of the baffle body 601 can be sucked into the liquid suction chamber 604 through the liquid suction holes 605, and the liquid in the liquid suction chamber 604 can be discharged in time through the guide pipe 4, thereby effectively preventing the accumulation of liquid flowing into the baffle body 601.

[0032] In some embodiments of the present invention, the implant guide further includes a tooth opening mechanism, which includes an opening base plate 5 and a plurality of opening protrusions 501 disposed on the opening base plate 5. The opening base plate 5 is disposed on the guide base 1 at a position away from the implant hole 2. That is, the opening base plate 5 is used to support the plurality of opening protrusions 501 and fix them to the guide base 1, and the opening protrusions 501 are used to abut against the upper teeth. In other words, by providing a tooth opening mechanism, it is convenient to open the patient's oral cavity during the implantation operation, thereby ensuring the smooth progress of the implantation operation.

[0033] Specifically, multiple support protrusions 501 are arranged at intervals along the length of the support base plate 5. Each support protrusion 501 is a long strip structure, parallel to each other, and the length extension direction of each support protrusion 501 is perpendicular to the length extension direction of the support base plate 5. This arrangement of the support protrusions 501 on the support base plate 5 facilitates cooperation with the upper dentition, thereby effectively resisting the upper dentition and ensuring the opening effect on the patient's oral cavity.

[0034] In some embodiments of the present invention, the guide plate base 1 is provided with an observation and verification window 8, which penetrates the guide plate base 1. By providing the observation and verification window 8, the patient can expose part of the tooth through the observation and verification window 8 after wearing the implant guide plate, thereby verifying whether the patient is wearing the implant guide plate securely.

[0035] In some embodiments of the present invention, the implantation guide plate further includes a visual marker connector 9, which is disposed on the guide plate base 1 at a position corresponding to below the observation and verification window 8. The visual marker connector 9 is provided with a visual marker slot 901 for inserting a visual marker into the visual marker slot 901. That is, by providing the visual marker connector 9, it is convenient to track the patient's position during visual navigation surgery, thereby marking the patient's spatial position through visual markers.

[0036] In some embodiments of the present invention, the visual marker connector 9 includes a front marker plate, a rear marker plate, a left marker plate, and a right marker plate. The front marker plate, the right marker plate, the rear marker plate, and the left marker plate enclose each other to form a visual marker slot 901. The upper end of the visual marker slot 901 is connected to the guide plate base 1, and the lower end of the visual marker slot 901 is a visual marker insertion port. That is, this structural arrangement of the visual marker connector 9 facilitates the pluggable installation of visual markers.

[0037] Specifically, raised or recessed text markings 10 are provided on the outer surface of the marking front plate of the visual marking connector 9. The text markings 10 can be used to distinguish different patients and implant guide design versions.

[0038] In some embodiments of the present invention, to prevent instability after the implant guide is worn by the patient due to issues such as the manufacturing precision of the implant guide, the guide base 1 includes a first movable base portion 101 and a second movable base portion 102 extending along the length direction, and the first movable base portion 101 and the second movable base portion 102 are detachably connected. That is, the guide base 1 can be divided into two independently movable first movable base portions 101 and second movable base portions 102, thereby enabling the first movable base portion 101 and the second movable base portion 102 to be installed separately on the patient's gums, thus making the implant guide more secure and stable to wear.

[0039] The length of the first movable base 101 is greater than the length of the second movable base 102. The implant hole 2, the lip blocking mechanism, the saliva suction mechanism, the observation and verification window 8 and the visual marker connector 9 are respectively disposed in the first movable base 101, and the tooth opening mechanism is disposed in the second movable base.

[0040] like Figure 2 As shown in the figure, this embodiment of the invention also provides a method for manufacturing a planting guide plate, used to manufacture the planting guide plate of the above embodiment, including: designing a planting guide plate model based on data flow nodes, the method specifically including the following steps: Based on the patient's three-dimensional tooth model, a guide plate matrix is ​​generated, forming data nodes 100 for the initial structure of the model.

[0041] The tooth-spreading mechanism is merged with the 3D model of the initial structure of the model through a Boolean operation to obtain data node 200 for the first combined structure of the model.

[0042] The lip-covering mechanism and the three-dimensional model of the first combined structure of the model are merged by Boolean operation to obtain data node 300 for the second combined structure of the model.

[0043] The saliva suction mechanism and the three-dimensional model of the second combined structure of the model are merged by Boolean operation to obtain data node 400 for the third combined structure of the model.

[0044] The visual marker connector is merged with the 3D model of the third combined structure of the model through Boolean operation to obtain data node 500 for the fourth combined structure of the model.

[0045] The text markers are merged with the 3D model of the fourth combined structure of the model through Boolean operations to obtain data node 600 for the fifth combined structure of the model.

[0046] Boolean operations are performed to merge the planting holes with the three-dimensional model of the fifth combination structure of the model to obtain data node 700 for the sixth combination structure of the model, and finally the planting guide plate model 800 is formed.

[0047] Specifically, the process of generating the 3D model of the saliva suction mechanism is as follows: Boolean operations are performed on the 3D models of the guide tube, the saliva suction cavity, and the saliva suction hole to obtain data node 900 for the saliva suction mechanism.

[0048] In this process, each step the user takes when designing the planting guide will generate a corresponding node, such as... Figure 2 The data flow node diagram shown clearly records all the operation processes, such as... Figure 2 Each box in the diagram represents a node, and the final planting guide can be adjusted by modifying each node in the node diagram.

[0049] In the above design process, each node can be viewed as a state or a specific operation. The left side of the node is the input terminal, accepting a set of inputs; the right side of the node is the output terminal, producing a set of outputs. Nodes are connected by lines, like a factory assembly line, transferring data from the initial state to the final state.

[0050] Starting with the generation of the guide plate matrix based on the patient's three-dimensional tooth model (data node 100 as the initial structure of the model), any subsequent operation of adding or deleting features on the model corresponds to a specific operation node in turn.

[0051] In certain nodes, basic parameters can be modified in the input boxes within the node, and the entire model will be automatically updated after the modification is completed. For example, the wall thickness and diameter of the saliva cavity can be modified in the node of the suction cavity; the content, depth, size of the text, and the concavity and convexity settings of the text on the visual marker connector can be modified in the node of the text marker.

[0052] When a node needs to be deleted, the corresponding feature in the 3D model will be removed. Selecting to add a new node and connecting it to the node graph will add the corresponding feature to the 3D model.

[0053] When node connections are disconnected, the positions of certain nodes can be adjusted. For example, if the location of the planting hole is found to be unsuitable, the node connection for the planting hole can be disconnected in the node diagram, and the position of the planting hole can be adjusted using controls in the 3D view. After adjustment, the corresponding node can be reconnected to the model data stream to update the planting guide model.

[0054] In other words, the planting guide fabrication method of this invention uses graphical data flow nodes to record the design operation steps of the planting guide, emphasizing the flow of 3D model data and defining the operation steps as a series of nodes and connections between nodes. All operations on the model can be viewed as combinations of nodes, which not only makes the entire planting guide design process more flexible and intuitive, saving design time, but also facilitates the modification and adjustment of the planting guide model. In other words, the planting guide fabrication method of this invention ensures traceable and modifiable operation steps when designing complex planting guides, avoiding the cumbersome problem of modifying the 3D model of the planting guide in existing design methods.

[0055] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
