Problems solved by technology

[0003] However, although the use of bonding and retention can solve the problem of the aesthetics of the anterior crown, the excess adhesive during the bonding process will flow below the anterior gum and remain under the gum, which will greatly increase the risk due to the residual adhesive. Probability of peri-implant inflammation caused later, and eventually lead to the possibility of implant failure
Although the method of using screw retention can avoid the use of adhesives and avoid the inflammation around the implant caused by it,

Embodiment 1

[0061] The embodiment of the present invention provides a mortise and tenon joint restoration design method applied to implant crowns in the aesthetic area, such as Figure 1-Figure 13 shown, including the following steps:

[0062] Step 1: Fix the implant 1 in the alveolar bone;

[0063] Step 2: after the implant 1 is integrated with the alveolar bone, install the porcelain abutment 2 on the upper end of the implant 1;

[0064] Step 3: Take the porcelain veneer 3, place the porcelain veneer 3 on the upper end of the porcelain abutment 2 along the surface of the porcelain abutment 2, and place the porcelain veneer 3 on the porcelain abutment 2 2 The connection is fixed by mortise and tenon connection.

[0065] The working principle and beneficial effects of the above-mentioned technical scheme are as follows: firstly, the implant 1 is fixed in the alveolar bone, and the implant 1 and the alveolar bone will be slowly combined. After the implant 1 and the alveolar bone are inte...

Embodiment 2

[0067] On the basis of above-mentioned embodiment 1, as Figure 2-Figure 10 As shown, the left and right sides of the porcelain base 2 are symmetrically provided with connecting blocks 4, and the connecting block 4 is provided with a first through hole 5, and the first through hole 5 runs through the front and rear side walls of the connecting block 4, The connecting block 4 and the porcelain abutment 2 are an integrated structure;

[0068] The porcelain veneer 3 is set as a wrapping type, and the upper end of the porcelain veneer 3 is provided with a convex plate 6, and the outer wall of the convex plate 6 facing the upper end of the porcelain abutment 2 is in contact with the outer wall of the porcelain abutment 2. Adapted, the inner side wall of the convex plate 6 is slidingly connected with the upper end of the porcelain abutment 2, and the left and right sides of the porcelain veneer 3 are symmetrically provided with side plates 7, and the side plates 7 wrap the connectin...

Embodiment 3

[0071] On the basis of Example 2, such as Figure 7 As shown, the connecting column 9 can be made by injecting 3M fluid resin into the first through hole 5 and the second through hole 8 .

[0072] The working principle and beneficial effects of the above-mentioned technical solution are as follows: the connecting column 9 can be made by injecting 3M fluid resin into the first through hole 5 and the second through hole 8 and then cured, thereby forming a unique " Mortise and tenon structure", the "mortise and tenon structure" can effectively prevent the porcelain veneer 3 from dislocating from the occlusal direction of the porcelain abutment 2 .

Abstract

The invention provides a mortise and tenon joint-type repair design method applied to dental crown implantation in a feature-beautifying area. The method comprises the following steps: fixing an implant in an alveolar bone; after the implant and the alveolar bone are combined into a whole, arranging a porcelain abutment at an upper end of the implant; and taking a porcelain veneer, placing the porcelain veneer at an upper end of the porcelain abutment in a sliding manner along a surface of the porcelain abutment, and fixedly connecting the ceramic veneer with the porcelain abutment in a mortise and tenon joint manner. A full dental crown is changed into an improved porcelain veneer, the personalized porcelain abutment matched with the porcelain veneer is designed, the porcelain veneer and the porcelain abutment are fixedly connected in the mortise and tenon joint manner, such that an adhesive is not needed, a problem of inflammation around the implant caused by the residual adhesive is avoided, a success rate of implantation is increased, the porcelain veneer is arranged and a problem of aesthetic defects of a dental crown lip side opening caused by screw retention is effectively solved.

Description

technical field [0001] The invention relates to the field of oral medical technology, in particular to a mortise and tenon joint restoration design method applied to implant crowns in aesthetic areas. Background technique [0002] At present, when designing the implant plan for the missing anterior teeth, due to the labial-glossal bone absorption of the alveolar bone after the missing anterior teeth, the design plan for implanting on the palatal side during implantation in the anterior tooth area, the long axis of the implant is inclined labially by 15 °Implanted into the implant site. However, in the second-stage restoration, an angled abutment is required to restore the crown to the normal anterior occlusal orientation. However, a long retaining screw is required to fix the angled abutment to the implant. Therefore, two crown designs have emerged. Solution 1. Adhesive retention: first connect the abutment to the implant through the retention screw, and then use professi...
