Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] see Figure 1 to Figure 4The stereotaxic device provided by the present invention includes an initial template 7 that matches the shape of the dental arch, and an approximately semicircular arc-shaped base plate 1. Several positioning protrusions 6 are arranged on the outer edge of the arc-shaped base plate 1, and the arc-shaped base plate 1 is snapped onto the initial template 7 through the positioning protrusion 6 . The curved substrate 1 is divided into a maxillary curved substrate and a mandibular curved substrate. A first cylinder 2, a second cylinder 3 and a third cylinder 4 parallel to each other are arranged on the concave surface of the maxillary curved substrate. A first cylinder 2 , a second cylinder 3 and a third cylinder 4 parallel to each other are arranged on the convex surface, and the line connecting the centers of the tops of the fir...

Abstract

The invention discloses a three-dimensional positioning device and a method for manufacturing an oral implantation guide plate by utilizing the same. The three-dimensional positioning device comprises an arc-shaped substrate, wherein the arc-shaped substrate is provided with a first cylinder, a second cylinder and a third cylinders, which are parallel; and free ends of the first cylinder, the second cylinder and the third cylinder are connected into a right-angled triangle. The method comprises the following steps that CT (Computed Tomography) scanning is carried out on the three-dimensional positioning device, a standard three-dimensional model of the device is reconstructed, a patient wears a radioactive guide plate with the three-dimensional positioning device for taking CT, data are imported into implantation software for simulating implantation, the standard three-dimensional modeling of the device is registered into the CT of the patient, space measurement is carried out on an implantation body on the basis of the standard three-dimensional model of the device, three-dimensional relation of the implantation body and the jawbone is accurately transferred onto an entity model, and then the oral implantation guide plate is manufactured by a mechanical perforating technology. The method is simple and convenient in operation, does not need to be dependent on special equipment, does not consume materials basically, is economic and practical, can be finished by independent operation of a doctor or a technician and has a good clinical application prospect.

Description

technical field [0001] The invention belongs to the technical field of making guide plates for oral cavity implantation, and in particular relates to a stereotaxic device and a method for making guide plates for oral cavity planting using the device. Background technique [0002] In the field of oral implantology, the concept of implant technology guided by prosthesis requires that the implant position can ensure the best function and aesthetics of the prosthesis, and it is easy to maintain. The routine application of implant guides is the key technology to realize this concept, which lays the foundation for ensuring the scientificity, correctness and accuracy of implant placement. Planting guides can be divided into CAD / CAM method and model method according to different manufacturing methods [0003] The CAD / CAM implant guide plate is combined with the patient's CT three-dimensional data, and it relies on expensive rapid prototyping equipment to complete the production. It...
