Description

Technical Field

[0001] This utility model relates to the field of oral medical equipment technology, specifically to a facebow scanning auxiliary mechanism. Background Technology

[0002] Surgery and treatment of the human face, especially in ENT (Ear, Nose, and Throat) surgery, often presents significant challenges. The human head, comprising the immobile skull and mandible, presents particular difficulties, especially in facial procedures. This is compounded by patients' fear of instruments on the face and the worry about potential cosmetic damage during surgery. Therefore, dental care, orthodontics, and facial plastic surgery pose considerable challenges for medical professionals. In the clinical practice of dental implantology, to ensure accurate and effective prosthesis fabrication, it is often necessary to transfer the positional relationship between the patient's upper and lower dentition and the temporomandibular joint to a dental articulator to simulate the patient's intraoral condition and guide the design and fabrication of the prosthesis.

[0003] One of the most crucial steps in prosthodontic treatment is transferring the 3D scan data of the patient's upper and lower jaw teeth models to a virtual articulator in dental design software to aid in prosthesis (denture) design. Currently, the common method involves first creating a plaster model, then using a physical mechanical facebow to transfer the plaster model's position onto a physical articulator, and finally using a matching scanning instrument to transfer the model's position from the physical articulator to the virtual articulator. However, to ensure the accuracy of the facebow scan data, it is necessary to scan the facebow from multiple angles and at different displacement positions. Currently, there is a lack of devices to assist in rotating and displacing the facebow during scanning, requiring manual adjustment of different angles and positions. This scanning process is cumbersome and time-consuming. Furthermore, the deformation of the impression material and plaster during the process inevitably introduces errors, thus affecting the accuracy of the treatment. Utility Model Content

[0004] This invention provides a face bow scanning auxiliary mechanism to solve the problem that the existing technology involves manually performing multi-angle and different displacement conversions on the face bow, which is complex, time-consuming, and affects the scanning accuracy.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A facebow scanning auxiliary mechanism includes an angle clamp, an arm clamp, a jaw fork, and a jaw fork arm. The jaw fork arm is inserted into the arm clamp via a dovetail groove structure. The rear end of the jaw fork is connected to the jaw fork arm via a pin. The angle clamp has an inverted U-shaped structure. The bottom two ends of the angle clamp are respectively connected to the arm clamp. The top of the angle clamp is provided with a facebow interface, and the middle of the angle clamp is provided with a locking connecting shaft.

[0007] An angle clamp is equipped with a face bow connecting rod on the side or top, and a face bow locking bolt is installed on the top of the face bow connecting rod.

[0008] When using this invention, the operator inserts the jaw fork arm into the arm clamp, and then connects the rear end of the jaw fork to the jaw fork arm via a pin. The jaw fork is connected to the patient's teeth via occlusal recording adhesive. The angle clamp above the arm clamp is connected to the facebow via the facebow interface or facebow locking bolt on the top or side. During scanning, the angle clamp adjusts the jaw fork to different angles via the locking connecting shaft. At the same time, the model's position can also be adjusted by adjusting the jaw fork arm to different positions within the arm clamp. This allows for the conversion of multiple angles and different displacements of the facebow, which is quick, convenient, and shortens the scanning process.

[0009] This invention is used to connect and adjust the facebow and the patient's teeth, enabling multi-angle and different displacement conversions of the facebow. The conversion is quick and convenient, effectively shortening the adjustment time and ensuring scanning accuracy. It has the advantages of simple structure, convenient use, and high efficiency.

[0016] Example 1, such as Figure 1 , Figure 2 and Figure 3 As shown, a face bow scanning auxiliary mechanism includes an angle clamp 1, an arm clamp 2, a jaw fork 3, and a jaw fork arm 4. The jaw fork arm 4 is inserted into the arm clamp 2 through a dovetail groove structure. The rear end of the jaw fork 3 is connected to the jaw fork arm 4 through a pin 5. The angle clamp 1 has an inverted U-shaped structure. The two ends of the bottom of the angle clamp 1 are respectively connected to the arm clamp 2. The top of the angle clamp 1 is provided with a face bow interface 6, and the middle of the angle clamp 1 is provided with a locking connecting shaft 7.

[0017] In use, the operator inserts the jaw fork arm into the arm clamp, and then connects the rear end of the jaw fork to the jaw fork arm via a pin. The jaw fork is connected to the patient's teeth via occlusal recording adhesive. The angle clamp above the arm clamp is connected to the face bow via the face bow interface at the top. During scanning, the angle clamp adjusts different angles of the jaw fork via a locking connecting shaft. At the same time, different positions of the model can also be adjusted by adjusting the different positions of the jaw fork arm in the arm clamp. This enables the conversion of multiple angles and different displacements of the face bow, which is quick and convenient and shortens the scanning process.

The main structure is the same as that of Example 1. A facebow connecting rod 8 is provided on the side of the angle clamp 1.
