AI Technical Summary
Existing oral locators have design flaws such as loosening due to gaps or stress concentration due to lack of gaps, resulting in low positioning accuracy and assembly difficulties, making it difficult to balance stability and convenience.
Design an oral locator with a stress-relief structure. By setting a stress-relief component between the locator body and the implant abutment, including a positioning groove and a stress-relieving hole, a seamless design is achieved to disperse stress and avoid stress concentration.
It improves the stability and ease of assembly of the locator body and the implant abutment, reduces assembly difficulty, extends service life, and ensures the quality and precision of dental implantation.

Abstract
Claims
1. A dental positioner with a stress-relieving structure, characterized in that, The device includes an implant abutment (1) located at a pre-designated implant site in the patient's oral cavity, a locator body (2) located on the implant abutment (1), and a stress relief assembly (3) located between the implant abutment (1) and the locator body (2). The stress relief assembly (3) includes a first positioning groove (30) located on the locator body (2) and stress relief holes (31) located on both sides of the first positioning groove (30) and communicating with the first positioning groove (30). The implant abutment (1) extends into the first positioning groove (30) so that the locator body (2) can be detachably mounted on the implant abutment (1).
2. An oral positioner having a stress relief structure according to claim 1, wherein, The locator body (2) includes a positioning post (20) and a positioning part (21) provided on the positioning post (20). The positioning post (20) and the positioning part (21) are distributed in a "T" shape. The first positioning groove (30) is provided on the positioning post (20).
3. An oral positioner having a stress relief structure according to claim 2, wherein, The locator body (2) also includes a second positioning groove (22) on the side of the positioning part (21) near the positioning post (20). When the locator body (2) is matched on the implant abutment (1), the second positioning groove (22) fits against the top of the adjacent tooth at the affected tooth.
4. An oral positioner having a stress relief structure according to claim 2, wherein, The stress relief hole (31) includes a main hole (310) on both sides of the positioning post (20) and a secondary hole (311) on the main hole (310) and connected to the main hole (310). The main hole (310) and the secondary hole (311) are arranged sequentially along the length direction of the positioning post (20).
5. An oral positioner having a stress relief structure according to claim 2, wherein, The locator body (2) also includes a first connecting hole (23) located on the top of the positioning part (21) and communicating with the first positioning groove (30).
6. An oral positioner having a stress relief structure according to claim 4, wherein, The diameter of the main hole (310) is defined as R, and the width of the secondary hole (311) is defined as r. R and r satisfy the following relationship: 1.5≤R / r≤2.
5.
7. An oral positioner having a stress relief structure according to claim 5, wherein, The implant abutment (1) includes a base (10) located at a pre-set tooth implantation site in the patient's oral cavity, a connecting seat (11) located on the base (10), and a second connecting hole (12) located on the connecting seat (11). When the locator body (2) is matched and located on the implant abutment (1), the first connecting hole (23) and the second connecting hole (12) are connected, and fasteners can be matched and located in the first connecting hole (23) and the second connecting hole (12) at the same time.
8. An oral positioner having a stress relief structure according to claim 7, wherein, The height of the base (10) is defined as H, and the height of the connecting seat (11) is defined as h. The relationship between H and h is as follows: 1.2≤H / h≤1.8.
