[0021] In combination with as Figures 1-5 shown, the technical solution is further described, a detachable horizontal impacted mandibular wisdom tooth tooth separation guide plate, comprising a support guide plate 1 matched and arranged on the lower alveolar of a patient, a tooth separation guide plate 2 arranged on the support guide plate 1, and a connecting assembly 3 arranged between the support guide plate 1 and the tooth separation guide plate 2, the tooth separation guide plate 2 is detachably connected to the support guide plate 1 through the connecting assembly 3, so that the tooth separation guide plate 2 is aligned with the affected tooth of the patient.

[0022] The application provides a detachable horizontal impacted mandibular wisdom tooth tooth separation guide plate, which comprises a support guide plate that can be matched and arranged on the lower alveolar of a patient, a tooth separation guide plate arranged on the support guide plate, and a connecting assembly arranged between the tooth separation guide plate and the support guide plate. By detachably arranging the tooth separation guide plate on the support guide plate and aligning the tooth separation guide plate with the affected tooth of the patient, the operator can accurately perform tooth separation surgery according to the positioning of the tooth separation guide plate on the affected tooth, significantly reducing the risk of complications such as tooth root fracture, without the need for positioning based on the operator's experience, significantly reducing the operation time, improving the operation quality, reducing the intraoperative wound area, improving the postoperative recovery speed of the patient, having the advantages of simple structure, easy operation, low preparation cost, one-time use, and easy popularization and implementation.

[0023] In actual implementation, during the tooth extraction surgery, the support guide plate is arranged on the lower alveolar of the patient, and the tooth separation guide plate is detachably arranged on the support guide plate, so that the tooth separation guide plate is aligned with the affected tooth of the patient, the deviation of the affected tooth from the panoramic image position is significantly reduced, the risk of complications such as tooth root fracture is reduced, and the operation time is reduced;

[0024] Through CT scanning of the jaw bone information of the patient and in-mouth scanner to obtain the tooth arrangement and soft tissue data of the patient, three-dimensional integrated data of the jaw bone and teeth are established, three-dimensional examination and positioning output of the wisdom tooth are performed on the three-dimensional data, the shape, position, length and surrounding bone condition of the impacted tooth are fully understood before the operation, to ensure that excessive bone removal does not occur during the operation and to ensure the strength of the lower jaw of the patient after the operation;

[0025] After the patient's oral cavity data is fully understood, the data is used to design and generate a tooth guide, a support guide and a connecting assembly in the pladstycad software. In the surgical process, the user uses the guide assembly without positioning according to the experience of the surgeon, significantly reduces the operation time, improves the operation quality, reduces the intraoperative wound area, improves the postoperative recovery speed of the patient, has the advantages of simple structure, easy operation, low preparation cost, one-time use, and easy popularization and implementation.

[0026] In the embodiment, the connecting assembly 3 includes a connecting groove 30 arranged on the support guide 1 and a connecting rod 31 arranged on the tooth guide 2 at a position corresponding to the connecting groove 30. The connecting rod 31 can be matched to extend into the connecting groove 30, so that the tooth guide 2 can be detachably arranged on the support guide 1.
