Description

Technical Field

[0001] The utility model belongs to the technical field of dental implant auxiliary equipment, and more specifically, relates to an impression transfer component and an impression transfer device. Background Art

[0002] During the oral implant restoration process, an impression of the oral implant area is required, and then a plaster model is made from the impression (i.e., mold). This is because the plaster model has the following advantages:

[0003] 1. Provide accurate anatomical structure

[0004] Teeth and gum morphology:

[0005] The plaster model can accurately reproduce the patient's tooth shape and gum contour, help understand the specific anatomical structure of the restoration area, and provide a detailed reference for the design and production of implant restorations.

[0006] Neighboring Organization Relationship:

[0007] The plaster model can show the relationship between the implant site and the surrounding teeth, gums and other oral tissues, helping dentists to make precise restoration designs and ensure the fit and functionality of the restoration.

[0008] 2. Help with implant and restoration design

[0009] Morphology and occlusion of the restoration:

[0010] Through the plaster model, dentists and technicians can design the restoration shape that suits the patient's oral structure, ensure the correctness of the occlusal relationship, and avoid adverse occlusal interference.

[0011] Implant position and angulation:

[0012] The plaster model can simulate the position and angle of the implant in the mouth (the impression is taken after the implant is placed, with the purpose of finding the specific position of the implant in the mouth. Because doctors are usually unable to accurately implant the implant in the specified position, an impression is needed to print out the specific position of the implant).

[0013] 3. Fabrication of temporary and permanent restorations

[0014] Temporary restoration:

[0015] After implant surgery, the plaster model can be used to create a temporary restoration to help patients maintain oral function and aesthetics while waiting for a permanent restoration.

[0016] Permanent restorations:

[0017] The plaster model provides an accurate reference for making permanent restorations, enabling technicians to make restorations that completely match the patient's oral structure based on the model, ensuring the comfort and stability of the restorations.

[0018] 4. Verify and adjust the repair plan

[0019] Experiment and tweak:

[0020] Plaster models can be used to test and adjust restorations. During the restoration fabrication process, technicians can try out the restoration on the model and make necessary adjustments and corrections to ensure that the final restoration fits perfectly in the patient's mouth.

[0021] Reduce errors:

[0022] By performing multiple verifications and adjustments on the plaster model, errors in the restoration production and installation process can be reduced and the quality and effect of the restoration can be improved.

[0023] 5. Facilitate communication and recording

[0024] Communicating with patients:

[0025] Plaster models can visually demonstrate oral conditions and restoration plans, help communicate treatment plans with patients, and enhance patients' understanding and trust in the treatment process and expected results.

[0026] Treatment Records:

[0027] The plaster model can be used as part of the treatment record to record the patient's oral condition and treatment process in detail, facilitating subsequent treatment and follow-up.

[0028] 6. Provide teaching and scientific research purposes

[0029] Teaching Tools:

[0030] Plaster models are important tools in dental education and can be used for teaching and training to help students and doctors understand and master implant restoration techniques.

[0031] Research references:

[0032] Plaster models can be used for scientific research, helping researchers conduct experiments and research on various oral implant restorations, and providing data support for the development of new technologies and new materials.

[0033] In summary, plaster models are crucial in dental implant restorations. They not only provide precise anatomical references, aiding the design and fabrication of patient-specific restorations, but also enable trial and adjustment to reduce errors and improve restoration quality. Furthermore, plaster models play a vital role in patient communication, documenting treatment progress, and supporting teaching and research. The creation and utilization of plaster models can significantly improve the success rate and patient satisfaction of dental implant restorations.

[0034] However, in the process of making the mold, the rod is usually installed on the implant, and then the solidifiable material is covered on the surface of the oral implant area (oral implant area: such as the gums), and the solidifiable material wraps the rod. After the solidifiable material solidifies, a mold that matches the shape of the oral implant area can be formed. After the mold is completed, the user can take the rod and the mold away together. Subsequently, a replacement body for replacing the implant needs to be installed on the rod, and then the replacement body is cast in the plaster through plaster. A shape that matches the shape of the oral implant area can be formed on the plaster, and the replacement body can act as an implant in the oral cavity, which is convenient for the user to simulate the implant in the user's mouth through plaster and the replacement body. However, axial movement or rotation is very easy to occur between the rod and the mold, which seriously affects the accuracy of the relative position between the rod and the mold.

[0035] The implant may refer to the implant disclosed in (China Utility Model Patent; Publication No.: CN220109870U; Subject Name: A Space-avoiding Structure, Implant, and Dental Implant Device; Publication Date: 2023-12-01).

In this way, after the rod body 1 is installed on the implant 3, the tray 5 can be placed on the gums 81 outside the rod body 1; the rod body 1 can pass through the first hole 51 on the tray 5; the user can inject a solidifiable substance into the interior of the recessed portion through the first hole 51 or the second hole 52, and the gas in the recessed portion can be discharged through the first hole 51 or the second hole 52. After the solidifiable substance solidifies into a mold 82, the mold 82 in contact with the gums 81 can obtain a predetermined surface 821 that is the same shape as the gums 81.

[0106] In one embodiment, the device further comprises: a base 6 ; the base 6 has an insertion end 61 that is the same as the plug end 12 .

[0107] In one embodiment, it further comprises: a denture 7 ; the denture 7 can be fitted onto the base 6 , making it convenient for the user to process the denture 7 .

[0108] In one embodiment, the abutment 6 is fixed to the replacement body 4 by means of bolts 86 .

[0109] In one embodiment, the bolt 86 and the screw 2 can be tightened with the same screwdriver.

[0110] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
