A rapid oral impression system

Abstract

This utility model discloses a rapid oral impression system, including a workbench, an oral scanner, a computer system, an intelligent design software system, a DLP photopolymerization 3D printer, and connecting cables. A handheld oral scanner is used to perform a comprehensive scan of the patient's oral cavity to generate three-dimensional data. A desktop DLP photopolymerization 3D printer uses medical-grade photosensitive resin to rapidly (as fast as 6 minutes) print a single crown model, shortening the oral impression taking time and temporary crown fabrication time, and reducing the cost of the 3D printer. This application solves the problems of long impression taking and temporary crown fabrication times, as well as the large size and high cost of the accompanying 3D printer, achieving one-stop restoration and avoiding secondary visits for patients.

Description

Technical Field

[0001] This utility model relates to the field of oral implant technology, specifically to a rapid oral impression system. Background Technology

[0002] Dental implants refer to a method of restoring missing teeth by using a substructure implanted into the bone tissue to support and retain the upper dental prosthesis. Current technology generally involves taking a traditional silicone rubber impression, which is then sent to an external manufacturer to fabricate a temporary crown, taking 1-2 days. The prosthesis is then installed during the patient's second visit.

[0003] For example, Chinese patent CN111904635B, published on February 24, 2023, discloses a precise impression-taking method and device for multi-tooth implants. The method includes the following steps: 1) installing the implant impression rod into the implant in the oral cavity; 2) using an intraoral scanner to scan and acquire three-dimensional point cloud data; 3) using software to edit and model, obtaining a three-dimensional fixation block model, with fixation holes set on the surface of the three-dimensional fixation block model; 4) using software to edit and model, obtaining a three-dimensional tray model, including a tray block, with a tray groove on the surface of the tray block and a fixation insertion hole on the bottom surface of the tray groove; 5) the three-dimensional fixation block model is 3D printed to obtain the fixation block, and the three-dimensional tray model is 3D printed to obtain the tray; 6) the fixation block is fitted onto the implant impression rod through the fixation holes, impression material is injected into the tray groove, the tray groove covers the fixation block, and after the impression material solidifies, it is removed, completing the impression taking. The impression taking method combines three-dimensional digital acquisition technology, digital design, and advanced manufacturing technology, which can achieve precise, fast, and efficient impression taking operation.

[0004] As can be seen from the above patents, the impression-taking process requires waiting for the impression material to solidify, resulting in long impression-taking and temporary crown fabrication times, as well as the large size and high cost of the accompanying 3D printer. Therefore, this utility model provides a rapid oral impression-taking system to solve the above problems. Summary of the Invention

The oral scanner 2, used for omnidirectional scanning of the patient's oral cavity to generate three-dimensional data, is movably connected to one side of the workbench 1. The oral scanner 2 is a handheld type, fully utilizing the human hand-eye coordination to achieve omnidirectional scanning, exceeding the degrees of freedom of multi-axis CNC motion structures. The handheld scanning head weighs ≤200g, has a resolution of 1920×1080, and a scanning accuracy of 50 μm, capable of generating STL model data in real time. The computer system 3, used for storing and processing the three-dimensional data, is placed on the workbench 1. The intelligent design software system 4, used for processing, designing, and outputting the three-dimensional data, is installed in the computer system 3. The intelligent design software system 4 has a built-in crown database and can automatically match the morphology of adjacent teeth and supports manual fine-tuning of edge fit by medical staff. The DLP light-curing 3D printer 5, used for printing solid models layer by layer, is placed on the workbench 1. The connecting cable 6, used for electrical connection and data transmission, connects the oral scanner 2 and the computer system 3.

[0032] In an optional embodiment, the DLP photopolymerization 3D printer 5 is a pull-type DLP photopolymerization 3D printer, including a support base 51, an optical system 52, a support platform 53, a resin tank 54, a lifting mechanism 55, and a control system 56 arranged sequentially from bottom to top. The optical system 52, which generates 405 nm ultraviolet light, is movably mounted on the support base 51 and under the support platform 53. The support platform 53, which supports the resin tank 54, is fixedly connected to the support base 51. The resin tank 54, which stores medical-grade photosensitive resin, is fixedly mounted on the support platform 53.

[0033] In an optional embodiment, the optical system 52 has its own motor movement system (not shown in the figure) to enable movement of the optical system 52; the control system 56 is electrically connected to and controls the optical system 52 and the lifting mechanism 55 respectively.

[0034] The working principle and usage process of this utility model are as follows:

[0035] First, a handheld dental scanner 2 performs a comprehensive scan of the patient's oral cavity to generate three-dimensional data (STL model data). The scanned STL model data is transmitted to the intelligent design software system 4 in the computer system 3 via the connection cable 6. The software automatically matches the morphology of adjacent teeth and supports manual fine-tuning of edge fit by medical staff. The optimized STL model data is copied to the desktop DLP photopolymerization 3D printer 5 via SD card or USB flash drive. The control system 56 is turned on, and with reference to the STL model data, the optical system 52 provides 405 nm ultraviolet light to cure medical-grade photosensitive resin in the resin tank 54 layer by layer. After each layer is exposed, the lifting mechanism 55 lifts it up to a certain height (the same as the layer thickness), so that the currently cured resin separates from the bottom of the resin tank 54 and adheres to the previous resin layer. This process is repeated, and through layer-by-layer exposure and lifting, a three-dimensional solid is finally formed.

[0036] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
