Description

Technical Field

[0001] The utility model relates to the technical field of dental models, in particular to a double-link articulator structure for 3D printing dental models. Background Art

[0002] In today's digital age, oral scanning technology is gradually changing the face of the oral medical field with its unique advantages. As an innovative means of oral diagnosis and treatment, oral scanning technology not only improves the diagnosis and treatment efficiency but also greatly enhances the patient's medical experience. As the name implies, oral scanning technology refers to the use of professional equipment to digitally scan the interior of the oral cavity to obtain accurate three-dimensional images. This technology can clearly display oral structures such as teeth, gums, and jaws, providing doctors with comprehensive oral health information. At the same time, through oral scanning technology, doctors can accurately measure the size, shape, and position of teeth, providing reliable data support for subsequent treatment.

[0003] Oral scanning technology also plays an important role in the field of orthodontics. For patients who need orthodontic treatment, traditional impression techniques may cause discomfort to them. Oral scanning technology can achieve painless and non-invasive dental impressions, allowing patients to complete the treatment in a relaxed and pleasant atmosphere. At the same time, oral scanning technology can also monitor the movement of teeth in real time, providing strong support for doctors to adjust treatment plans. In addition, oral scanning technology has the advantages of environmental protection and high efficiency. Compared with the traditional method of making plaster models, oral scanning technology does not require the use of consumables such as plaster, reducing environmental pollution. At the same time, due to the rapid and accurate digital scanning process, doctors can quickly obtain the oral data of patients, shortening the treatment cycle and improving work efficiency.

[0004] When turning the digital model into a physical model in the doctor's hand for clinical diagnosis and medical teaching, it is through 3D printing technology to transform the digital model into a physical model. In the digital model, the occlusal relationship of the model is fixed by the computer three-dimensional coordinate system. After being transformed into a physical model, the upper and lower jaw models are separated, resulting in a change in the occlusal relationship. Therefore, to solve the above problems and help doctors more intuitively analyze the shape, position, and occlusal relationship of teeth on the physical model, the present invention proposes a double-link articulator structure for 3D printing dental models, ensuring that the 3D printed model can retain its original digital coordinate system and also for shortening the printing time and reducing consumables.
