Description

Technical Field

[0001] This utility model relates to the technical field of intraoral scanners, and in particular to an intraoral scanning auxiliary device and system. Background Technology

[0002] An intraoral scanner is a digital device in the dental field, primarily used to acquire three-dimensional data of the oral cavity's internal structures. Resembling a small probe, it is inserted into the patient's mouth by the dentist. Using optical scanning technology (such as laser or structured light), it quickly captures the morphology of tissues like teeth and gums, transmitting the data in real-time to a computer to generate a high-precision three-dimensional model.

[0003] Most existing intraoral scanners are optical scanning devices that acquire three-dimensional morphology of the oral cavity (such as 3Shape) through optical data. (etc.). Its working principle is to acquire the surface morphology of static oral structures (teeth, gums) through optical lenses and generate a digital model. However, it has the following limitations:

[0004] 1. It can only collect static models of the mucosa in a relaxed state, and cannot simulate the dynamic morphology of the gums being pressed and sinking during chewing.

[0005] 2. During the scanning process, the air gun needs to be used frequently to dry the saliva, which affects the efficiency of the operation.

[0006] 3. The lack of an effective mechanism to separate the gingiva from the crown margin leads to insufficient scanning accuracy in the shoulder area.

[0007] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as static acquisition without dynamic simulation, the need to dry saliva, and insufficient accuracy in the shoulder area. Utility Model Content

[0055] 1.

During scanning, the air pressure detection unit adjusts the airflow pressure in real time (simulating the pressure of teeth on the gums during chewing), pushing the gingival tissue downwards. Simultaneously, the temperature detection unit is triggered to maintain the airflow temperature consistent with the oral cavity temperature, avoiding irritation to the mucosa. This allows for dynamic capture of gingival morphological changes after pressure, overcoming the shortcomings of traditional static scanning in reflecting the state of chewing function. It is particularly suitable for scenarios requiring precise gingival margin morphology, such as implant restorations and full crown preparation.

[0056] 2. By using the air outlet unit to move synchronously with the scanning head, a gentle airflow is automatically sprayed before or during scanning to quickly dry saliva or gingival crevicular fluid, replacing the traditional manual air gun operation and improving the ease of operation.

[0057] 3. When scanning the crown shoulder area, the air pressure detection unit is adjusted so that the airflow from the air outlet unit cuts into the gap between the gingival margin and the crown. The fluid dynamics principle is used to gently push open the gingival tissue and expose the hidden shoulder edge, thus improving the shoulder scanning accuracy. The second fixing unit is used to stabilize the mounting unit so that the airflow pressure is stably transmitted to the front end of the scanning head. Attached Figure Description

[0176] The method of using this utility model is as follows:

[0177] (I) Installation

[0178] Place the mounting element 141 in the designated position (at the bottom of the intraoral scanning head B);

[0179] Install the third fixing element 161 around the scanning head B, install the fourth fixing element 162 around the scanning head B, and connect the fourth fixing element 162 to the third fixing element 161.

[0180] During the process, the third fixing element 161 and the fourth fixing element 162 are extended and retracted accordingly based on the radial size of the intraoral scanning head B;

[0181] Place the main component 111 at the designated position (located at the top of the intraoral scanning handle A, and the distance between the main component 111 and the mounting component 141 should not be too large or too small, that is, the distance between the main component 111 and the mounting component 141 should be adapted to the axis of the flow guiding unit 130, to avoid the distance being too small, which would cause the flow guiding unit 130 to become loose, and to avoid the distance being too large, which would cause the flow guiding unit 130 to be overstretched).

[0182] Install the first fixing element 121 around the scanning handle A, install the second fixing element 122 around the scanning handle A, and connect the second fixing element 122 to the first fixing element 121.

[0183] During the process, the first fixing element 121 and the second fixing element 122 are extended and retracted accordingly based on the radial size of the intraoral scanning handle A;

[0184] The first channel element 112 is connected to the gas generating equipment.

[0185] (II) Scanning

[0186] The patient rinsed their mouth with saline solution to pre-treat the oral cavity and reduce initial saliva production.

[0187] Place the intraoral scanning head B against the target area (such as the posterior teeth area) to perform the scanning operation.

[0188] (III) Generating airflow

[0189] Start the gas generating equipment to deliver the gradually pressurized airflow to the first channel element 112. The first channel element 112 delivers the airflow into the interior of the mounting element 141 through the flow guiding unit 130 and the second channel element 142, and the airflow is delivered to the second air outlet element 151 by the first air outlet element 143. Finally, the airflow is discharged through the third air outlet element 152 until the mucosa sinks.

[0190] The airflow cuts into the space between the gingival margin and the crown, gently pushing aside the gingival tissue using the principles of fluid dynamics, thus exposing the hidden shoulder edge;

[0191] The continuous airflow covers and clears away saliva;

[0192] During the process, the airflow temperature is detected by the temperature sensing element 171 and the air pressure is detected by the air pressure sensing element 181.

[0193] After the scan is completed, the system automatically generates a 3D model of the pressure imprint.

[0194] The advantages of this utility model are:

[0195] 1. By utilizing the cooperation between the main unit and the first fixing unit, the main unit can be integrated into the scanning handle and connected to the mounting unit installed on the scanning head via the airflow guiding unit, allowing for the directional delivery of airflow to the gingival region. During scanning, the air pressure detection unit adjusts the airflow pressure in real time (simulating the pressure of teeth on the gums during chewing), pushing the gingival tissue downwards. Simultaneously, the temperature detection unit is triggered to maintain the airflow temperature consistent with the oral cavity temperature, avoiding irritation to the mucosa. This allows for dynamic capture of gingival morphological changes after pressure, overcoming the shortcomings of traditional static scanning in reflecting the state of chewing function. It is particularly suitable for scenarios requiring precise gingival margin morphology, such as implant restorations and full crown preparation.

[0196] 2. By using the air outlet unit to move synchronously with the scanning head, a gentle airflow is automatically sprayed before or during scanning to quickly dry saliva or gingival crevicular fluid, replacing the traditional manual air gun operation and improving the ease of operation.

[0197] 3. When scanning the crown shoulder area, the air pressure detection unit is adjusted so that the airflow from the air outlet unit cuts into the gap between the gingival margin and the crown. The fluid dynamics principle is used to gently push open the gingival tissue and expose the hidden shoulder edge, thus improving the shoulder scanning accuracy. The second fixing unit is used to stabilize the mounting unit so that the airflow pressure is stably transmitted to the front end of the scanning head.
