Embodiment 1

[0076] refer to figure 1 and figure 2 , the immediate load-bearing transitional denture comprises a fixedly connected base 1 and a denture restoration 2 , and a retaining pin seat 3 is fixedly connected to one side of the base 1 .

[0077] The base 1 is arc-shaped and conforms to the contour of the gums in the oral cavity. A matching groove 11 is concavely formed on the side of the base 1 away from the denture restoration 2 , and the matching groove 11 matches the contour of the gum soft tissue. The base 1 can be made of flexible materials, and the manufacturing method can be 3D printing.

[0078] The denture restoration body 2 includes a plurality of denture units that are fixedly connected, and two adjacent denture units can be fixed by connecting rods, so that the plurality of denture units are connected as a whole. The denture restoration 2 and the base 1 can be polymerized into one through light curing. The denture restoration body 2 is provided with at least one fixi...

Embodiment 2

[0081] refer to image 3 , the immediate load-bearing combination device includes a planting guide and a retaining nail guide.

[0082] The retaining nail guide may have the same structure as the immediate load-bearing transitional denture, and in other embodiments of the present application, the retaining nail guide may only include a base 1 and a retaining nail seat 3 .

[0083] The implantation guide includes a base 1 and a retaining nail seat 3 , and a plurality of implant holes 12 are opened on the base 1 on the side corresponding to the denture restoration body 2 . After the implant guide is worn on the gum, the implant can be installed at the corresponding position of the gum through the implant hole 12 .

[0084] The positions of the retaining nail bases 3 on the retaining nail guide and the planting guide are the same on the base 1 .

[0085] The instant load combination device is used as follows:

[0086] First, the retaining pin guide is put on the gums in the or...

Embodiment 3

[0091] A digital preparation method of an instant load combination device, comprising the following steps:

[0092] A radiological denture is produced, and a plurality of marking parts capable of CT imaging are pre-set on the radiological denture. refer to Figure 4 and Figure 5 , Radial denture consists of base 1 and denture restoration 2. A mounting groove 13 for mounting the denture restoration 2 may be provided on the base 1 .

[0093] The radiological denture is inserted into the oral cavity and the gums are in an occlusal state, and a CT scan is performed on the oral cavity in the occlusal state to form a second digital model. like Image 6 As shown, since the soft tissue of the gums and the base 1 cannot be visualized, the imaged parts at this time are the mandibular bone 6, the gum bone 5 and the blocking point 4 formed by the visualization of the marking part.

[0094] A CT scan of the radiological denture forms a first digital model. At this time, the CT radia...

Abstract

The invention relates to an immediate load-bearing transition denture, a combination device and a digital preparation method, and relates to the technical field of dental restoration.The immediate load-bearing transition denture comprises a base plate, the base plate is provided with a matching groove used for being matched with the gum tissue contour; the denture prosthesis is connected to the base plate, a fixing hole is formed in the denture prosthesis and/or the base plate, and the fixing hole is used for fixing the denture on an implant; the retention nail seat is provided with at least two retention nail holes penetrating through the base plate; the combined device comprises an immediate load-bearing transition false tooth, a retention nail guide plate and an implantation guide plate, the digital preparation method comprises the steps that a first digital model and a second digital model are established and matched, planting holes and retention nail holes are established in the first digital model, three-dimensional digital models of the planting guide plate, the retention nail guide plate and the immediate load-bearing transition false tooth are generated respectively, and the three-dimensional digital models are printed through 3D. The application has the advantage of being beneficial to immediately loading the transitional denture after the implantation operation is completed.

Description

technical field [0001] The present application relates to the technical field of dental restoration, and in particular, to an immediate load-bearing transitional denture, a combined device and a digital preparation method. Background technique [0002] Teeth are the basis for ingesting nutrients to maintain good health. When teeth on the gums fall out, dental implant surgery is generally used for full dental implants. The method of dental implant is as follows: the implant is placed on the gum bed through the implant guide, and then the denture is fixed on the implant to complete the restoration of the lost tooth. [0003] When there is no teeth on the gums, the surface of the gums is soft tissue, the soft tissue is pulled by the lips during the operation, and the soft tissue is swollen and deformed after the operation. As a result, it takes a long time to make an immediate load-bearing denture due to the deformation of the soft tissue after the implant is implanted. Waitin...
