Description

How to make an implant abutment

The present disclosure relates generally to a method of making an implant abutment, and more particularly to a method of making an implant abutment without a model made from gypsum.

This section provides background information related to the present disclosure which is not necessarily prior art.

1 is a view showing an example of an implant, the implant is coupled to the implant fixture (10; Implant Fixture), the prosthesis (20; Prosthesis) and the implant fixture (10) to support the prosthesis (20) Abutment (30) is included. The abutment 30 is fixed to the implant fixture 10 by a screw 32 in a state in which the connecting portion 31 is inserted into the implant fixture 10.

2 is a view showing an example of a method for manufacturing a prosthesis in the related art. First, in the state in which the abutment 30 is coupled to the implant fixture 10, the impression is taken using the impression material 40. Impression acquisition includes impression acquisition of the surrounding tooth 60.

Next, after the abutment analog 33 is inserted into the obtained impression body 41, a plaster gypsum is floated. After the plaster is hardened, the impression body 41 is removed to obtain a model 50 having the abutment analog 33 fixed thereto.

The prosthesis 20 is designed and manufactured on the obtained model 60.

3 is a view showing another example of a method for manufacturing a prosthesis in the related art. After a certain period of time after implantation of an implant fixture, a healing abutment is removed to expose the implant fixture 10. Impression Coping (35) is inserted into the.

Next, the impression body 41 is obtained through the impression taking, and the implant analog 11 having the same shape as the implant fixture 10 is positioned through the impression coping 35.

Next, the model 50 is made of plaster. In the model 50, the implant analog 11 corresponding to the actual implant fixture 10 is fixed. When the impression coping 35 is removed, the model 50 can be used to design the abutment or the prosthesis. have.

The conventional abutment design / manufacturing and / or prosthesis design / manufacturing requires a gypsum mockup 50, but errors due to cure expansion of gypsum, time consuming due to cure swelling, and mockup 50 There are a number of problems such as locational constraints to move to butt and / or prosthetic fabrications, and fear of model 50 breakage.

This is described later in the section titled 'Details of the Invention.'

This section provides a general summary of the disclosure and is not a comprehensive disclosure of its full scope or all, provided that this is a summary of the disclosure. of its features).

According to one aspect of the present disclosure (According to one aspect of the present disclosure), in a method of making an implant abutment, the virtual information corresponding to the shape of the oral cavity is obtained by acquiring information of the oral cavity in which the implant fixture is located. A first step of forming a model; In addition, a second step of designing an implant abutment on a virtual model is provided. A method of making an implant abutment is provided.

This is described later in the section titled 'Details of the Invention.'

1 is a view showing an example of an implant,

2 is a view showing an example of a method for manufacturing a prosthesis in the related art;

3 is a view showing another example of the conventional method for producing a prosthesis,

4 and 6 are views showing an example of making an implant abutment according to the present disclosure,

7 illustrates another example of designing an implant abutment in accordance with the present disclosure.

The present disclosure will now be described in detail with reference to the accompanying drawing (s).

4 and 6 are views illustrating an example of making an implant abutment according to the present disclosure. Referring first to FIG. 4, an impression acquisition using an impression material 40 is performed, through which an impression body 41 is formed. Obtained. At this time, impression coping or scan coping 36 may be used. Preferably, the scan coping 36 is made of a material (eg, plastic such as POM, PEEK, PC, etc.) in which light is not reflected or minimized. This is for accurate recognition of the scan coping 36 because the scan coping 36 may not be easy to recognize the scan coping 36 in the scan process described below when the scan coping 36 is a metal material. Reference numerals are implant fixtures 10 and teeth 60.

Next, the obtained impression 41 is scanned through the scanner 71 connected to the computer 70 with the scan coping 36 inserted therein, and thus the surface of the impression 41 and the scan coping 36. A three-dimensional image 37 (see Fig. 5) having information is formed.

Next, referring to FIG. 5, a virtual model 53 for designing the abutment 30 using the three-dimensional image 37 is formed on a computer. As in FIG. 3, when the design of the abutment 30 is made on the model 50 using the gypsum bone, the implant analog 11 is already provided in the model 50, but in the case of the present disclosure, the gypsum Since the model 50 using the bone is not manufactured separately, it is necessary to introduce the virtual implant analog 15 corresponding to the actual implant fixture 10 or the implant analog 11 in the virtual model 53.

To this end, information about the implant analog 11 is added to the virtual model 53. The addition of information on the implant analog 11 may be made in the process of making the virtual model 53 from the three-dimensional image 37, or after the virtual model 53 is made from the three-dimensional image 37. At this time, in order for the implant analog 11 corresponding to the implant implant 10 actually placed to be used, information about the implant fixture 10 is required, which can be secured in the process of implantation, and if necessary, It may be obtained by investigating. It can also be viewed on a computer by using scan coping 36 corresponding to a particular implant fixture 10. The virtual implant analog 15 can be easily applied to the virtual model 53 by having various models in the computer and selecting them according to the implant fixture 10 or the implant analog 11. Here, the three-dimensional image 37 and the virtual model 53 have been described in the form of being distinguished. However, when the three-dimensional image 37 formed through scanning is used as it is, the three-dimensional image 37 itself is the virtual model 53. Of course, it can be used as.

Next, the abutment 30 is designed. Meanwhile, the design of the prosthesis 20 may precede the design of the abutment 30. In this case, there is an advantage that the degree of freedom in designing the prosthesis 20 is increased.

Finally, as shown in FIG. 6, the information about the designed abutment 30 is sent to the machining equipment 80 to cut the abutment 30. Preferably, the machining part of the abutment 30 can be reduced by using the blank in which the connecting portion 31 corresponding to the shape of the implant fixture 10 is already shaped. The material of the blank may be Titanium, Titanium Alloy, Co-Cr Alloy, Sintered Zirconia, Green stage Sintered Zirconia, Tilite Alloy, Ni-Cr Alloy. NC (Numerical Control) machining can be used, for example.

FIG. 7 is a view showing another example of designing an implant abutment according to the present disclosure. Unlike the example illustrated in FIG. 4, the process of forming the virtual model 53 is performed without forming the impression body 41. . That is, the three-dimensional image 37 is made by scanning the oral cavity using the scanner 72 connected to the computer 70. The process after the three-dimensional image 37 is obtained in the same manner as the example shown in FIGS. Reference numerals are scan coping 36 and tooth 60.
