Method for designing implant prosthesis

A design method and prosthetic technology, which can be used in implants, dentistry, prosthetics, etc., can solve the problems of inability to plan the optimal shape of abutment teeth, loss of tooth arrangement information, and influence on the combination relationship, so as to save production time. As well as the cost, the accuracy of the implant prosthesis, and the obvious effect of the connection interface

Problems solved by technology

[0003] Since the connection interface of the traditional artificial implant is not obvious, after scanning the reproduced oral model with a computer, only the digital data of the oral model can be obtained, and the digital data of the artificial implant cannot be accurately obtained
In addition, since the combination of the artificial implant and the abutment tooth has a specific configuration, that is, the combination and positioning of the two have a specific directionality, so if the digital data of the artificial implant cannot be accurately obtained, if the abutment tooth If the relevant design and adjustment are carried out, it is very likely to get an incorrect abutment tooth, which will affect the combination relationship between the abutment tooth and the imitation, and the optimal shape of the abutment tooth cannot be planned. Loss of clear tooth bite relationship information reduces the accuracy of subsequent denture bites, and loss of clear tooth arrangement information reduces the aesthetic function of dentures after dental implants

Embodiment 1

[0060] Such as figure 1 As shown, the design method of dental implant prosthesis, which includes the following steps:

[0061] a) Setting reference fixtures in the oral cavity: such as Figure 2 to Figure 5 As shown, under the condition that there is a fixture (fixture) 11 in the oral cavity of the patient, a reference fixture 13 corresponding to the fixture 11 is selected and combined with the fixture 11. The reference fixture 13 has a plurality of reference Fixture feature point 14, a plurality of reference fixture feature points 14 are exposed on the gingiva in the patient's oral cavity and the outer surface of the implant 11, wherein the top of the implant 11 is provided with a connection interface 115, and the bottom of the reference fixture 13 is Correspondingly, a first docking interface 135 is provided, and the implant 11 and the reference jig 13 are combined with the first docking interface 135 through the connecting interface 115 .

[0062] Wherein, the plurality o...

Embodiment 2

[0077] see again Figure 16 ~ Figure 18 As shown, the design method of the dental implant prosthesis provided by Embodiment 2 of the present invention differs from Embodiment 1 in that:

[0078] In step a), the patient's oral cavity is provided with a plurality of implants (not shown in the figure);

[0079] In step c), during positioning, the digital implant prosthesis 33 selected from the prosthesis database (not shown) stored by the computer (not shown in the figure) is a digital precision prosthesis 33 in Embodiment 2. Dental Precision Bar. The digital precision dental bar is combined with the virtual implant 111. In addition, the digital precision dental bar can be used as a tooth row design for multiple teeth, or a removable denture (Denture) can be fixed thereon.

[0080] During actual manufacture, the form of the digital precision tooth bar can have many kinds.

[0081] Figure 16 As shown, the shape of the digital implant prosthesis 33 (that is, the digital precisi...

Abstract

The invention belongs to the technical field of artificial implant, in particular, to a method for designing implant prosthesis, which comprises the following steps: a) providing a reference fixture in a mouth cavity; b) scanning: scanning the inside of the mouth cavity, obtaining digital data and then storing into a computer; c) locating: obtaining digital implant prosthetic positioning and connection interfaces with the configuration of digital data; and d) adjusting and designing: adjusting digital implant prosthesis, so as to obtain the implant prosthesis suitable for a patient. The invention has the following advantages of 1. a mouth cavity solid model needs not be reproduced, production time and cost are saved, the reproduction of the distortion caused by model is avoided to obtain more accurate prosthetic implant; 2. the connection interface of the implant is more obvious, a relationship between the digital implant prostheses and the implant is more precise, the most appropriate type of the prosthetic implant is regulated, a clear relationship between the teeth on the bite information is obtained and the accuracy of dentures on bite is improved.

Description

Technical field: [0001] The invention belongs to the technical field of artificial dental implants, in particular to a design method of a dental implant prosthesis. Background technique: [0002] Existing dental implant designs all need to reproduce the oral cavity model in production, and the oral cavity model contains at least one analog (analog), and the analog implant is simulated to be implanted on the patient's bone; then design A dental implant prosthesis (such as an artificial support tooth (Abutment)), is used to combine with the artificial implant; finally, a crown is designed, and the crown is set on the dental implant prosthesis, which completes the whole Dental implant design. [0003] Since the connection interface of the traditional artificial implant is not obvious, after scanning the reproduced oral cavity model with a computer, only the digital data of the oral cavity model can be obtained, but the digital data of the artificial implant cannot be accuratel...
