Problems solved by technology
Using the optical positioning device or the display of the screen, the dentist can properly adjust the design and position of the implant according to the patient's current condition during the operation. However, since there is no physical guide component similar to the implant board, it cannot provide A stable and physically fixed drilling direction for the dentist
[0004] In addition, dentists often need to use medical imaging equipment to obtain the spatial information of the patient's jawbone when performing oral medical diagnosis, or use intraoral scanning to obtain information on the distribution of oral teeth; however, because imaging equipment or intraoral scanning When the device itself intercepts image information, errors will inevitably occur, causing dentists to make misjudgments in terms of spatial dimensions or angles during dental implant surgery, increasing surgical risks, and possibly causing medical disputes
[0005] Based on the shortcomings of the above-mentioned existing technologies, it can be seen that the current known technologies cannot provide a correct, stable, and real-time (Real-time) monitoring environment for dental implants. In addition, the accuracy of the equipment itself is insufficient, causing dentists to prefer to perform dental implants by themselves. Explore the depth and angle of dental implants, and don't want to trust computer-aided equipment

Embodiment Construction
[0031] In order to describe the technical features of the present invention in detail, the following preferred embodiments are given below and described in conjunction with the drawings. Such as figure 1 As shown, a computer-aided positioning and navigation system 410 for dental implants provided by the first preferred embodiment of the present invention mainly consists of a digital dental system 411, an implant guide plate 421, at least one optical capture device 431 and a display Device 441 is formed. Such as figure 1 As shown, the computer-aided positioning and navigation system 410 is provided with an optical capture device 431. In other embodiments, in order to improve the accuracy of the detected orientation and angle, two or three optical capture devices 431 can be set for Let the implant planning software 412 capture the location information of multiple different spatial points, and then obtain higher-precision coordinate information through three-dimensional (3-Dime...

The invention discloses a digital implantation guide plate with an optical navigation function and a use method of the digital implantation guide plate. The digital implantation guide plate comprisesa body and at least one positioning piece, wherein the body is movably arranged on the dental arch of the oral cavity of a patient, and the positioning piece is arranged at the side edge of the body.Oral cavity tomography is performed on the patient to obtain a plurality of tomography images; and the implantation guide plate and the positioning piece are shot at the same time to obtain a space vector V1 of the implantation guide plate, and the tomography images, the implantation guide plate and the oral cavity condition of a human body can be showed on one piece of display equipment.
Description
technical field [0001] The present invention relates to a digital implant guide plate for dentistry, in particular to a digital implant guide plate with optical navigation function and its usage method. Background technique [0002] With the development of image processing technology and positioning aids, dentistry has realized the introduction of computer-aided positioning technology into dental implant surgery. Traditionally, 2D (two-dimensional) oral scan image data of preoperative patients are used to extract the jawbone tissue parts through image processing, reconstruct the model using the digital element model reconstruction algorithm, and load the planning software for implant planning and design of positioning auxiliary devices. A positioning aid is produced by machining to form a device similar to a dental implant. This kind of device can provide a physically fixed drilling direction during the operation, but it is still placed in the patient's mouth according to t...
