Description

Technical Field

[0001] The utility model relates to the technical field of anterior tooth implant temporary restorations, in particular to an anterior tooth implant temporary restoration. Background Art

[0002] The temporary restoration of anterior teeth is a temporary restoration, which is a temporary restoration that the patient cannot freely take off and wear after the tooth preparation for fixed restoration and before the final fixed restoration is completed. Temporary crowns are the most common, and are a conventional restoration method for clinically repairing various discolored teeth, tooth defects and missing teeth. Because the production of its restoration takes a certain amount of time, it cannot be worn immediately. During this period, since the abutment teeth have no adjacent and occlusal relationship after preparation, they are prone to tilting, elongation, and displacement. For vital teeth, pulp irritation symptoms or even pulpitis may occur, which can easily affect the positioning and tightness of the restoration and cause serious adverse consequences. Therefore, a temporary restoration must be made.

[0003] However, the current methods of making temporary restorations for patients' anterior teeth require multiple trial fittings, adjustments, and trimming inside the patient's mouth. The restorations touch the patient's bad teeth many times, which increases the patient's pain. The operation is cumbersome and affects the installation efficiency of the temporary restorations. The existing digital guide technology is often used for patients' tooth restorations, and the digital implant guide is a tool to assist implant surgery. Implant surgery, which is mainly restoration-oriented, requires accuracy in the depth, direction, and position of the implant, which cannot be fully achieved by the naked eye and experience alone. Therefore, a guide is needed for precise positioning. The guide uses a computer to accurately scan the patient's mouth and make an accurate model based on the patient's actual situation to facilitate the patient's tooth restoration operation. However, there is currently no application of digital guide technology to temporary dental restorations. When patients install temporary restorations for their anterior teeth, they still need to endure a lot of pain.

[0004] Therefore, there is a need for a method that can provide patients with quick, convenient and accurate production and installation of temporary restorations for anterior tooth implants based on digital guide technology. Utility Model Content

[0027] See also Figure 1-5 As shown, the utility model provides the following technical solutions: a temporary restoration for anterior tooth implantation, comprising a first digital guide plate model 1, a bad tooth model 3 is arranged on the first digital guide plate model 1, a second digital guide plate model 5 is arranged above the first digital guide plate model 1, and a bad tooth model sleeve 7 is arranged on the second digital guide plate model 5. For details, please refer to the attached Figure 2 and attached Figure 3, the two digital guide plate models are accurate models made by 3D printing after scanning the patient's oral teeth based on the digital guide plate technology. The specific operation method and principle belong to the existing technology, and the application of digital guide plates in tooth restoration in the existing technology can be referred to. The bad tooth model 3 is consistent with the patient's front teeth to be repaired. The bad tooth model sleeve 7 is a hollow structure and can be sleeved on the outside of the bad tooth model 3. The top of the bad tooth model sleeve 7 is connected through and provided with an injection component 8 for injecting resin to make a temporary restoration of the bad tooth; the first digital guide plate model 1 is provided with a first model tooth 2, and the bottom of the first digital guide plate model 1 is provided with a base plate 4; the second digital guide plate model 5 is provided with a second model tooth 6, and the first model tooth 2 and the second model tooth 6 are both provided with a plurality of The second model tooth 6 is a hollow structure, and the outer size of the first model tooth 2 is matched with the inner size of the second model tooth 6, that is, the second model tooth 6 can be mounted on the outside of the first model tooth 2; this solution applies digital guide technology to temporary restorations, and uses digital guide technology to accurately make a patient's tooth model, and at the same time makes an adaptive tooth model sleeve. When making a temporary restoration of the front teeth for the patient, the tooth model sleeve is put on the tooth model, and then the resin is injected to make a temporary restoration at the bad tooth model, which can be directly placed on the inside of the patient's mouth. It is easy to operate and can be made accurately, avoiding the conventional multiple fillings and trimming of the restoration directly on the inside of the patient's mouth, which causes inconvenience in operation and poor patient experience.

[0028] Reference Figure 4 and Figure 5As shown, specifically, the injection assembly 8 includes a first injection pipeline 81, an accumulation capsule 82, a blocking capsule 83 and a second injection pipeline 84. One end of the second injection pipeline 84 is connected to the top of the bad tooth model sleeve 7. When injecting resin, the two digital guide plate models need to be inverted so that the resin is injected from the bottom. The inner side of the second injection pipeline 84 is fixedly connected with a blocking capsule 83. The two ends of the blocking capsule 83 are fixedly connected to the inner wall of the second injection pipeline 84. The size of the blocking capsule 83 is matched with the inner size of the second injection pipeline 84. The blocking capsule 83 can block the inner side of the second injection pipeline 84, but the outer wall of the blocking capsule 83 is not completely connected to the inside of the pipeline. The other end of the second injection pipeline 84 is connected to the accumulation capsule 82, and one side of the accumulation capsule 82 is connected to the first injection pipeline 81; the accumulation capsule 82 and the blocking capsule 83 are both made of elastic material; the outer wall of the blocking capsule 83 The middle part of the part fits with the inner wall of the second injection pipeline 84. When it is compressed, the blocking capsule 83 can make way for the flow channel; the outer wall of the second injection pipeline 84 is symmetrically provided with through holes 841 for discharging the air inside the blocking capsule 83 to avoid the situation where the blocking capsule 83 cannot be squeezed, and the through hole 841 is connected to the blocking capsule 83; in this scheme, the injection component 8 is set, and when the resin is injected between the bad tooth model sleeve 7 and the bad tooth model 3, the pipeline can be blocked by the blocking capsule 83, so that the resin is collected on the inner side of the accumulation capsule 82, and the air and bubbles inside are discharged with the continuous injection of the resin, and then the blocking capsule 83 shrinks under the liquid pressure to make way for the second injection pipeline 84, and then the resin can stably fill the space between the bad tooth model sleeve 7 and the bad tooth model 3 from the bottom, thereby forming a temporary restoration, avoiding the situation where the conventional syringe is directly injected, the injection is unstable, and bubbles are easily generated.

[0029] Reference Figure 5 As shown, specifically, one end of the first injection pipeline 81 is fixedly connected with a bucket-shaped connecting sleeve 811, which can connect the ends of syringes of different models. An elastic extrusion ring 812 is fixedly provided on the inner wall of the bucket-shaped connecting sleeve 811. The elastic and raised extrusion ring can tighten and seal the end of the inserted syringe to prevent air from entering.

[0030] The working principle and use process of the utility model are as follows: when making a temporary restoration of the front teeth for the patient, a bad tooth model 3 and a bad tooth model sleeve 7 that meet the actual situation of the patient are made through digital guide plate technology, and an injection component 8 on the bad tooth model sleeve 7 is made simultaneously. After the bad tooth model sleeve 7 is set on the bad tooth model 3, the operator turns the two upside down, and injects the resin forming the temporary restoration from the bottom to the bad tooth model 3 and the inside of the bad tooth model sleeve 7 through the injection component 8. After the resin fills the gap between the two and takes shape, the two models are separated to obtain the temporary restoration. The operator simply trims the edges of the temporary restoration and then fixes it directly to the bad tooth in the patient's mouth through paraffin, etc. The operation is convenient, and it avoids the situation where multiple trimming and debugging on the inside of the patient's mouth increase the patient's pain.
