Description

Technical Field

[0001] This utility model relates to the field of oral scanning, and in particular to a splicing centric jaw tray for oral scanning. Background Technology

[0002] Intraoral scanning is a sampling technique used in dentistry to create edentulous bite records. Current sampling methods involve the dentist creating a occlusal frame based on a plaster model taken from the patient's mouth, then placing a wax rim on the frame. The wax rim is used to adjust and determine the centric relationship, correct vertical distances and horizontal relationships, check the occlusal plane position, and mark the midline and corner of the mouth line to confirm the centric occlusal relationship within the patient's mouth. The model and bite record are then sent to a dental lab via express delivery, where they are used to create a dental model of the patient. A more advanced method involves directly scanning the patient's oral cavity with an intraoral scanner to record the dentition data. However, the bite relationship still requires the dentist to extract a plaster model and send it to the dental lab via express delivery to determine the correct bite relationship. Application number 202422854569.6 discloses "a centric jaw tray for oral scanning". However, the existing centric jaw tray is a one-piece structure, which needs to be placed into the mouth as a whole. The scanner head has a certain size, which will cause a busy scanning area in the oral cavity, resulting in incomplete and inaccurate scanning. In addition, the existing tray structure is large in size, making it difficult to place the tray into the patient's mouth for patients with limited oral space. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the background art and provide a spliced ​​centric chin tray for intraoral scanning. This centric chin tray has a detachable structure and can be spliced ​​with different tray components according to the patient's shape, which effectively improves the accuracy of intraoral scanning.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A spliced ​​median jaw tray for intraoral scanning includes a central plate, wing plates, and a fixing rod. The central plate is arc-shaped, and detachable wing plates can be installed on both sides of the central plate. Outer edge baffles are machined on the outer sides of the central plate and the wing plates. A handle extending outward is machined in the middle of the outer edge baffle of the central plate. Locking pins are machined on both sides of the central plate. Locking seats for connecting to locking seats are machined on the wing plates. Limiting seats are machined at both ends of the fixing rod. Limiting pins adapted to the limiting seats are machined on the opposite sidewalls of the two wing plates.

[0006] The handle is integrally formed with the middle plate.

[0007] The surfaces of the middle disc and the wing disc are machined with hollowed-out through holes, and a limit groove is machined on one side of the middle disc and the wing disc near the outer edge baffle.

[0008] The beneficial effects of the spliced ​​median jaw tray for intraoral scanning provided by this utility model are:

[0009] (1) The tray, which is composed of the middle plate and the wing plate, can be disassembled and scanned separately according to the patient's actual situation, which solves the problem of the tray being restricted in the mouth and effectively improves the accuracy of the oral scan.

[0010] (2) By machining limiting grooves on one side of the middle disc and the wing disc, the patient can still make occlusal records, which increases the sampling function of the tray. Attached Figure Description

[0016] Example

[0017] like Figures 1-3As shown, the spliced ​​median jaw tray for oral scanning provided in this embodiment includes a central disc 1, wing discs 2, and a fixing rod 3. The central disc 1 is arc-shaped, and detachable wing discs 2 can be installed on both sides of the central disc 1. Outer edge baffles 5 are machined on the outer sides of the central disc 1 and the wing discs 2. A handle 4 extending outward is machined in the middle of the outer edge baffle 5 of the central disc 1. The handle 4 is integrally formed with the central disc 1. Clips 8 are machined on both sides of the central disc 1. A clip 9 connected to a clip 9 is machined on the wing disc 2. Limiting seats 10 are machined at both ends of the fixing rod 3. Limiting pins 11 adapted to the limiting seats 10 are machined on the opposite side walls of the two wing discs 2. To improve the sampling range of the tray, the surfaces of the middle plate 1 and the wing plate 2 are machined with hollow through holes 7, and the side of the middle plate 1 and the wing plate 2 near the outer edge baffle 5 is machined with a limiting groove 6. By installing silicone rubber impression material on the tray, an interlocking relationship can also be created.

[0018] The method of using this utility model is as follows:

[0019] In use, according to the patient's sampling position, the pins 8 on both sides of the middle disc 1 are connected to the slots 9 on the adjacent wing disc 2, and then the wing discs 2 on both sides are connected by the fixing rod 3 to complete the production of the oral scanning tray. If the patient cannot be inserted completely, one side of the wing disc 2 can be removed for separate oral scanning. This greatly facilitates patients with restricted access. After oral scanning, the assembled tray is taken out, and silicone rubber impression material is installed on the tray. It is then placed back into the patient's mouth, allowing the patient to close it voluntarily. After removal, the impression material will retain the patient's occlusal relationship. That is, the tray disclosed in this patent can not only perform oral scanning but also create occlusal relationships.

[0020] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by this utility model should be covered within the protection scope of this utility model. It should be noted that the structures or components illustrated in the accompanying drawings are not necessarily drawn to scale, and descriptions of well-known components, processing technologies, and processes are omitted to avoid unnecessarily limiting this utility model.
