Description

Technical Field

[0001] This utility model relates to the field of oral medical implant technology, specifically to an optical calibration accessory for oral implant navigation. Background Technology

[0002] In modern digital dental implantology, to improve the success rate and accuracy of the surgery, dental implant navigation equipment is currently used as an aid. The specific process is as follows: the patient takes a CT scan—the patient's CT scan is imported into the implant navigation equipment; the CT data is edited using specialized software, including the selection of the implant drill bit, confirmation of the implant site and implant depth; registration points are established for subsequent fitting of the CT scan with the patient's actual oral cavity data—the implant tool, such as the implant handpiece, is registered to obtain the position and axial information of the implant handpiece head; the data is fitted; and navigation is performed.

[0003] During implantation tool registration, the calibration accessories used need to be sterilized before installation. Insecure installation can lead to registration failures or misalignment of the handset head and axial information after successful registration, affecting subsequent fitting data and navigation. Furthermore, this registration process is time-consuming, typically around 5 minutes, increasing time costs for both doctors and patients. Existing implantation navigation system calibration accessories are often made of polymers, ceramics, and aluminum alloys, requiring reassembly after sterilization during calibration. Polymer materials have several drawbacks: high-temperature, high-pressure sterilization results in a 0.05-0.2mm deformation, causing Mark point spatial coordinate shifts; repeated sterilization leads to surface oxidation, affecting optical recognition accuracy; existing fixing structures are prone to loosening due to differences in thermal expansion coefficients; and combined structures experience stress deformation under high-temperature conditions.

[0004] To address the aforementioned issues, we have made improvements by proposing an optical calibration accessory for dental implant navigation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides an optical calibration accessory for dental implant navigation, including a horizontal calibration rod, a vertical calibration rod fixedly disposed in the middle of the horizontal calibration rod, a circular mark point on the front of each end of the horizontal and vertical calibration rods, an annular mark point on the front of the bottom end of the vertical calibration rod, and a docking block fixedly disposed in the middle of the back of the vertical calibration rod near the top, with a positioning hole opened in the center of the top surface of the docking block.

[0007] As a preferred embodiment of this invention, the horizontal calibration rod has a convex handle at the center of its back side.

[0008] In a preferred embodiment of this invention, the horizontal calibration rod and the vertical calibration rod intersect at their respective center positions and are perpendicular to each other.

[0009] As a preferred embodiment of this invention, the annular Mark point is located above the circular Mark point at the bottom of the vertical calibration rod, and the four circular Mark points are of the same size.

[0010] As a preferred embodiment of this utility model, the bottom of the docking block is fixedly connected to the top surface of the convex handle.

[0011] As a preferred embodiment of this utility model, the horizontal calibration rod, handle, vertical calibration rod, and docking block are all made of aluminum alloy.

[0012] The beneficial effects of this utility model are as follows: This optical calibration accessory for dental implant navigation, based on existing optical calibration accessories, uses aluminum alloy material, which can prevent unexpected deformation during disinfection or other processes, and it is modified into an integrated structure, eliminating the need for assembly during surgery, thus saving doctors time during the registration process. The positioning hole that matches the size of the implant handpiece calibration pin can greatly ensure stability during the registration process, thereby obtaining more accurate handpiece head position and axial information.
