Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to an oral implant guide. Background Technology

[0002] An implant guide is an important auxiliary tool used in oral implant surgery. Its main function is to guide the precise position and direction of the implanted teeth, ensuring a proper relationship between the implant and the surrounding tissues. It can improve the accuracy and success rate of oral implant surgery, bringing better treatment results and experience to patients.

[0003] For example, a dental implant guide with Chinese authorization announcement number CN 220344525 U discloses a dental implant guide that can solve the problem that the inner diameter of the through hole opened at the bottom of the guide body cannot be changed according to the diameter of the drill bit, thus reducing the applicability of the device.

[0004] However, most dental implant guides currently available cannot be precisely positioned according to the distribution of teeth in the patient's oral cavity during fixation, resulting in movement during dental implantation and poor flexibility in use, which reduces the effectiveness of dental implantation. Utility Model Content

[0005] Therefore, this application provides an oral implant guide to solve the problems of existing transparent guides that cannot be accurately positioned according to the distribution of teeth in the patient's oral cavity and have poor flexibility of use.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An oral implant guide includes a transparent guide body, an injection hole and a positioning groove. A prefabricated cavity is provided through the middle of the transparent guide body, and a mounting frame is provided on the outer side of the transparent guide body. A through hole is provided through the upper end of the mounting frame.

[0008] The transparent guide plate body has injection holes that are opened through it at equal angles on its side wall, and the inner wall of the transparent guide plate body has a molding groove that is connected to the injection holes. The inner wall of the transparent guide plate body is provided with a transparent film.

[0009] The transparent guide plate body has positioning grooves at equal angles inside, and a partition is inserted into the positioning groove.

[0010] Furthermore, the transparent film is located on the outer side of one end of the forming groove near the central axis of the transparent guide plate body, and the transparent film is in contact with the partition plate.

[0011] Furthermore, both the upper and lower ends of the transparent film are connected to the transparent guide plate body by adhesive bonding.

[0012] Furthermore, the cross-sections of the positioning groove and the partition are both "T" shaped structures, and the injection holes and the positioning groove are distributed at intervals.

[0013] Furthermore, one end of the partition extends into the interior of the forming groove, and the upper end of the partition extends to the outer side of the upper end of the transparent guide plate body.

[0014] Furthermore, the mounting bracket is slidably connected to the transparent guide plate body, and a fixing screw is installed through the lower end of the mounting bracket.

[0015] Furthermore, the lower end of the transparent guide plate body is provided with threaded holes at equal angles that are compatible with the fixing screws.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] 1. Inject the thermoplastic material into the newly divided molding groove through the corresponding injection hole. At this time, the thermoplastic material can contact the transparent film and fit the tooth, thus better outlining the shape of the tooth. Then, use an ultraviolet lamp to irradiate the injected thermoplastic material. Under the irradiation of the ultraviolet lamp, the thermoplastic material begins to polymerize, and the liquid thermoplastic material gradually transforms into a solid polymer. Similarly, select 1 or 2 teeth to perform the above operation, which can improve the placement effect of the transparent guide plate. It can effectively and accurately position the transparent guide plate according to the distribution of teeth, avoid the transparent guide plate moving during the dental implantation, and improve the subsequent dental implantation effect.

[0018] 2. The lower end of the transparent guide plate body has threaded holes at equal angles that are compatible with the fixing screws. The combination of fixing screws and threaded holes provides a good fixing effect for the mounting bracket, making it easy to securely install the mounting bracket at the designated position on the outside of the transparent guide plate body. At the same time, the design of the threaded holes allows the whole system to implant teeth in different positions, improving the overall flexibility of use.

[0019] 3. By inserting the partitions into the corresponding positioning slots of the adjacent gaps of the tooth, the partitions provide auxiliary support for the transparent film, making it easier for the transparent film to connect tightly with the tooth. This allows the transparent film to better wrap around the outside of the tooth, making it easier to outline the shape of the tooth. At the same time, the partitions also act as dividers to prevent excessive flow of thermoplastic material. Attached Figure Description

It should be understood that the specific shapes and structures shown in the drawings should not generally be regarded as limiting conditions for implementing this application; for example, based on the technical concept disclosed in this application and the exemplary drawings, those skilled in the art are capable of making conventional adjustments or further optimizations to the addition / reduction / classification of certain units, their specific shapes, positional relationships, connection methods, size ratios, etc.

[0027] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 4 As shown, an oral implant guide in the first aspect embodiment of this application includes a transparent guide body 1, an injection hole 3 and a positioning groove 6. A prefabricated cavity 2 is provided through the middle of the transparent guide body 1, and a mounting bracket 8 is provided on the outer side of the transparent guide body 1. A through hole 9 is provided through the upper end of the mounting bracket 8.

[0029] The prefabricated cavity 2 serves to install the transparent guide plate body 1, facilitating downward movement of the transparent guide plate body 1 through the occlusal force between the prefabricated cavity 2 and the patient's posterior alveolar bone, allowing the transparent guide plate body 1 to be inserted into the patient's tooth through the prefabricated cavity 2. Simultaneously, the mounting bracket 8 serves to install the through hole 9.

[0030] The transparent guide plate body 1 has an injection hole 3 through it at an equal angle on its side wall, and a molding groove 4 that is connected to the injection hole 3 is opened on the inner wall of the transparent guide plate body 1. A transparent film 5 is provided on the inner wall of the transparent guide plate body 1, and the upper and lower ends of the transparent film 5 are connected to the transparent guide plate body 1 by means of adhesive.

[0031] The transparent film 5 is located on the outer side of the forming groove 4 near the central axis of the transparent guide plate body 1, and the transparent film 5 has a certain degree of elasticity, which facilitates the outer side of the transparent film 5 away from the forming groove 4 to contact the patient's teeth. When the transparent guide plate body 1 is inserted into the patient's teeth through the pre-made cavity 2, the transparent film 5 deforms under the action of biting force, and can wrap around the outer side of the teeth according to the shape of the teeth.

[0032] Meanwhile, the injection hole 3 plays a good role in injecting thermoplastic materials, making it convenient to inject thermoplastic materials into the molding groove 4 through the injection hole 3, so that the thermoplastic materials can come into contact with the transparent film 5 wrapped on the teeth.

[0033] The transparent guide plate body 1 has a positioning groove 6 opened at equal angles inside, and a partition 7 is inserted into the positioning groove 6. The cross-section of the positioning groove 6 and the partition 7 are both "T" shaped. The injection hole 3 is distributed at intervals with the positioning groove 6, and the transparent film 5 is in contact with the partition 7.

[0034] The positioning grooves 6 are set one-to-one with the gaps in the teeth, so that the two sets of partitions 7 can be inserted into the corresponding positioning grooves 6, so that the partitions 7 and the transparent film 5 are tightly connected, and the transparent film 5 can better wrap the outside of the teeth, making it easier to outline the shape of the teeth.

[0035] Meanwhile, one end of the partition 7 extends into the interior of the molding groove 4, and the upper end of the partition 7 extends to the outer side of the upper end of the transparent guide plate body 1, which facilitates the separation of the molding groove 4 by the partition 7, and makes it convenient to install and remove the partition 7 through the extended part, thereby improving the ease of use.

[0036] The mounting bracket 8 is connected to the transparent guide plate body 1 by sliding. A fixing screw 10 is installed through the lower end of the mounting bracket 8. Threaded holes 11 that are adapted to the fixing screw 10 are opened at equal angles inside the lower end of the transparent guide plate body 1.

[0037] The combination of fixing screw 10 and threaded hole 11 provides a good fixation for the mounting bracket 8, making it easy to securely install the mounting bracket 8 at the designated position on the outside of the transparent guide plate body 1. At the same time, the design of threaded hole 11 allows the whole system to implant teeth in different positions, improving the overall flexibility of use.

[0038] Working principle

[0039] First, the transparent guide plate body 1 is placed in the patient's mouth, and the patient's occlusal force of the posterior alveolar bone is used to hold the transparent guide plate body 1 into the patient's tooth through the prefabricated cavity 2, causing the transparent film 5 to deform and wrap around the outer side of the tooth. Select one of the patient's teeth, and insert the partitions 7 into the corresponding positioning grooves 6 in the adjacent gaps of that tooth. At this time, the partitions 7 provide auxiliary support for the transparent film 5, making it easier for the transparent film 5 to be tightly connected to the tooth, so that the transparent film 5 can better wrap around the outer side of the tooth and better outline the shape of the tooth. At the same time, the partitions 7 also act as a separator to prevent excessive leakage of thermoplastic materials such as resin.

[0040] Thermoplastic material is injected into the newly separated molding groove 4 through the corresponding injection hole 3. At this time, the thermoplastic material can contact the transparent film 5 and conform to the tooth, thus better outlining the shape of the tooth. Then, the injected thermoplastic material is irradiated with ultraviolet light. Under the irradiation of the ultraviolet light, the thermoplastic material begins to polymerize, gradually transforming the liquid thermoplastic material into a solid polymer. Similarly, by selecting one or two more teeth for the above operation, the placement effect of the transparent guide plate body 1 can be improved. It can effectively and accurately position the transparent guide plate body 1 according to the distribution of the inner teeth, avoiding the displacement of the transparent guide plate body 1 during tooth implantation, and improving the subsequent implantation effect.

[0041] Adjust the position of the mounting bracket 8 on the outside of the transparent guide plate body 1 so that the mounting bracket 8 and the transparent guide plate body 1 are slidably connected until the mounting bracket 8 moves the through hole 9 to the desired implanted tooth. Then rotate the fixing screw 10 so that the fixing screw 10 is inserted into the corresponding threaded hole 11, so that the fixing screw 10 and the threaded hole 11 are threadedly connected, thereby fixing the position of the mounting bracket 8 and the through hole 9, which facilitates the subsequent guidance of the implanted tooth through the through hole 9.

[0042] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
