[0005] Furthermore, the first clasp includes two clasp arms and a support, the two clasp arms are symmetrically ring-shaped and embrace the middle part of the natural abutment tooth, and the free ends of the two clasp arms away from the symmetry axis have greater elasticity for retaining the first clasp, and the starting ends of the clasp arms close to the symmetry axis have less elasticity for stabilizing the first clasp, and the support is vertically arranged on the symmetry axis of the two clasp arms, and the support is pressed on the top of the natural abutment tooth.

[0006] Furthermore, the second clasp includes two symmetrically arranged clasp arms and a fitting plate, the two clasp arms are engaged with the middle part of the natural abutment, and the fitting plate is arranged on the symmetry axis of the two clasp arms and fits with the lower part of the natural abutment.

[0007] Furthermore, a first support body is provided between the two ends of the front jaw retaining body.

[0008] Furthermore, a second support body is arranged between the first base and the second base.

[0009] Furthermore, the front jaw retainer, the first base, the second base, the first clamping ring, the second clamping ring, the first support body and the second support body are integrally formed and manufactured by selective laser cladding technology.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] The through holes on the first base are arranged in an arc along its length, and an artificial tooth is installed in one through hole. The shape of the lower part of the artificial tooth used to connect to the first base is fixed, thus facilitating the subsequent production and replacement of artificial teeth and reducing the cost of artificial teeth; the through holes on the second base are arranged in a grid, and the diameter of the through holes is smaller than the diameter of the through holes on the first base. Therefore, when artificial teeth are installed in the through holes on the second base, one artificial tooth is installed through multiple through holes, and the arrangement of several artificial teeth can be selected according to the actual situation of the user, so as to achieve installation arrangements with different arcs, which is more suitable for the user. At the same time, since the bottom of an artificial tooth is fixed in different through holes respectively, the bottom of the artificial tooth on the second base has more force points than the artificial tooth on the first base, the force is more balanced, and the installation is more stable.

[0012] The first clasp and the second clasp are used to reduce the torque of the terminal abutment and increase the stability of the denture. The elastic free end of the clasp arm enters the concave area of ​​the natural abutment to effectively fix and prevent the denture from dislocating. The support can prevent the denture from gingival displacement and keep the position of the first clasp on the natural abutment unchanged, and can also prevent the first base from sinking, protect the health of the periodontal tissue of the abutment and the soft and hard tissues in the edentulous area, and at the same time can disperse and transmit the occlusal force to the abutment. The second clasp is made to fit tightly against the natural abutment through the bonding piece, and the position of the second base is fixed to prevent the second base from displacement.

[0013] The front jaw retainer, the first base, the second base, the first clamping ring, the second clamping ring, the first support body and the second support body are formed into a single piece of cobalt-chromium alloy powder by selective laser cladding technology, which is convenient and quick to manufacture and avoids the complexity of traditional processes.

It should be noted that since the through holes 11 on the first base 2 are arranged in an arc along its length direction, and one artificial tooth is installed in one through hole 11, the shape of the lower part of the artificial tooth used to connect with the first base 6 is fixed, which facilitates the subsequent production and replacement of artificial teeth and reduces the cost of artificial teeth; the through holes 11 on the second base 3 are arranged in a reticular manner, and the diameter of the through holes 11 is smaller than that of the first base 2, so when the through hole 11 on the second base 3 is used to install the artificial tooth, one artificial tooth is installed through multiple through holes 11, and the arrangement of several artificial teeth can be selected to be installed in different through holes 11 according to the actual situation of the user, so as to achieve installation arrangements with different arcs, which is convenient for better adaptation to the user. At the same time, since the bottom of an artificial tooth is fixed in different through holes 11 respectively, the force points at the bottom of the artificial tooth on the second base 3 are more than those on the first base 2, the force is more balanced, and the installation is more stable. However, due to the large number of through holes 11, it is more troublesome and costly to replace the artificial teeth later.

[0024] The first clasp 4 includes two clasp arms 6 and a support 7. The two clasp arms 6 are symmetrically ring-shaped and embrace the middle part of the natural abutment tooth. The free ends of the two clasp arms 6 away from the symmetry axis have greater elasticity and are used to retain the first clasp 4. The starting ends of the clasp arms 6 close to the symmetry axis have less elasticity and are used to stabilize the first clasp 4. The support 7 is vertically arranged on the symmetry axis of the two clasp arms 6, and the support 7 is pressed on the top of the natural abutment tooth.

[0025] The elastic free end of the clasp arm 6 enters the concave area of ​​the natural abutment tooth to effectively fix and prevent the denture from dislocation. The support 7 can prevent the denture from gingival displacement and keep the position of the first clasp 4 on the natural abutment tooth unchanged, and can also prevent the first base 2 from sinking, protect the health of the periodontal tissue of the abutment tooth and the soft and hard tissues in the edentulous area, and at the same time disperse and transmit the occlusal force to the abutment tooth.

[0026] The second clasp 5 includes two symmetrically arranged clasp arms 6 and a fitting sheet 10. The two clasp arms 6 are engaged with the middle of the natural abutment. The fitting sheet 10 is arranged on the symmetry axis of the two clasp arms 6 and fits with the lower part of the natural abutment.

[0027] The second clasp 5 is closely attached to the natural abutment tooth through the bonding sheet 10 , and the position of the second base 3 is fixed to prevent the second base 3 from being displaced.

[0028] Specifically, the anterior jaw retainer 1, the first base 2, the second base 3, the first clasp 4 and the second clasp 5 are integrally formed by selective laser cladding technology. During the production, a digital anatomical impression is obtained by a 3shape intraoral scanner, and then converted into a functional impression by Geomagic software. Cobalt-chromium alloy powder is integrally formed without the need to make an intraoral impression, and the production accuracy and suitability are good.

[0032] Specifically, a second support body 9 is disposed between the first base 2 and the second base 3 .

[0033] When in use, the first support body 8 and the second support body 9 are placed under the user's tongue root. The first support body 8 ensures the shape of the front jaw retainer 1 to avoid deformation of the front jaw retainer 1. The second support body 9 can further fix the positions of the first base 2 and the second base 3 to avoid displacement of the first base 2 and the second base 3.

[0034] Specifically, the front jaw retainer 1, the first base 2, the second base 3, the first clamping ring 4, the second clamping ring 5, the first support body 8 and the second support body 9 are integrally formed and manufactured by selective laser cladding technology.
