Description
Technical Field

Background
Dental implantation refers to a method of tooth missing restoration in which an upper dental prosthesis is supported and retained on the basis of a substructure implanted in bone tissue. It adopts artificial material (such as metal, ceramic, etc.) to make implant (generally similar to tooth root form), and adopts the operation method to implant into tissue (generally upper and lower jaws) and obtain firm retention support of bone tissue, and utilizes special device and mode to connect and support the dental prosthesis of upper portion.
Among the options for the tooth loss restoration, the tooth implantation restoration is becoming more popular. The implantation precision of the implant directly affects the position accuracy of the final implanted denture, and in order to obtain an ideal repair effect, the position, the angle and the depth of the implant are ensured by using the implant guide plate. The method is characterized in that computer aided design and manufacturing technology is adopted abroad, namely, a jaw three-dimensional model is reconstructed through a patient jaw face CT image before a tooth implanting operation, a proper implant type is selected according to jaw image data, a digital operation guide plate is selected and designed by combining information such as teeth, bone mass and the like of an implant, and finally, a total implantation operation scheme is obtained. Therefore, the doctor can realize safe and accurate implantation operation by utilizing the operation guide plate, not only can prevent the lower alveolar nerve from being damaged and puncture the maxillary sinus floor, but also can ensure that the implant is placed at an ideal position.
Whether the digital operation guide plate is used for implantation is determined to be inaccurate due to the selection of a guide plate supporting mode and a positioning reference to a great extent, or the position of implant implantation is inaccurate due to the fact that the support is poor and the implant is deviated in the operation process, so that the implantation operation fails or the repair of the implanted false tooth fails, and how to improve the positioning precision of the implantation operation guide plate is the same problem faced by many researches.
