The whole implant consisting of the implant, the implant abutment and the implant crown can repair the missing tooth in the oral cavity of a patient, so that the missing tooth is replaced to realize the functions of beautifying the oral cavity and chewing food.
The internal conditions of the oral cavity of each patient are different, so that a good repairing effect can be achieved only by installing the implant matched with the oral cavity, otherwise, the dental implant cannot be effectively repaired, and other healthy teeth can be damaged more seriously. Therefore, before the dental implant operation, it is necessary to prepare an implant, an implant abutment, and an implant crown in advance according to the internal condition of the oral cavity of a patient.

In order to solve the above problems, as shown in fig. 1, the present invention provides a method for manufacturing a personalized abutment, the method comprising the steps of:
s1, obtaining three-dimensional data in a patient mouth, wherein the three-dimensional data in the patient mouth comprises missing tooth and gum three-dimensional data. The method comprises the steps of firstly acquiring three-dimensional data in a patient mouth, and preparing for determining the most ideal personalized abutment three-dimensional data matched with the three-dimensional data by taking the missing tooth and gum three-dimensional data as a reference.

Therefore, the three-dimensional data of the personalized abutment is generated by combining the gingival contour, the gingival penetrating height and the cuff form, the intraoral condition of a specific patient can be well matched, the implant tooth and the gingiva are perfectly matched, and the gap between the implant tooth and the gingiva is reduced.
And S4, obtaining the personalized abutment according to the three-dimensional data instantiation of the personalized abutment, wherein the gum contour, the gum penetrating height and the cuff shape of the personalized abutment are matched with the three-dimensional data of the missing gum.

Therefore, based on the technical scheme, after the data such as the gum outline, the gum penetrating height, the cuff shape and the like are obtained by obtaining the three-dimensional data in the mouth of the patient, the three-dimensional data of the personalized abutment is generated, and the personalized abutment is obtained by instantiation according to the three-dimensional data of the personalized abutment, so that the corresponding personalized abutments can be manufactured according to the internal conditions of the oral cavity of different patients, accurate matching is realized, and the repairing effect of the implanted teeth is improved.
Preferably, in order to ensure the occlusion efficiency after the completion of the planting repair, the method comprises the following steps:
obtaining three-dimensional data in a patient's mouth, wherein the three-dimensional data in the patient's mouth comprises three-dimensional data of missing teeth and gingiva and three-dimensional data of contralateral teeth. The implant and the contralateral tooth are close to each other in the occlusion process, and under the normal condition, the size between the implant and the contralateral tooth needs to be matched with each other, so that the normal occlusion effect can be guaranteed.
And determining the gingival contour, the gingival penetrating height and the cuff shape according to the three-dimensional data of the missing gingiva, and determining the abutment height according to the three-dimensional data of the contralateral teeth. And determining the height of the abutment corresponding to the three-dimensional data of the contralateral teeth.
Generating personalized abutment three-dimensional data by combining the gingival contour, the transgingival height, the cuff form and the abutment height;
and instantiating according to the three-dimensional data of the personalized abutment to obtain the personalized abutment, wherein the gingival contour, the gingival penetrating height, the cuff shape and the abutment height of the personalized abutment are matched with the three-dimensional data of the missing gingiva.
Based on the technical scheme, the height of the abutment is determined through the three-dimensional data of the contralateral tooth, so that a gap is prevented from being formed between the implant and the contralateral tooth after the implant operation is implemented or collision is prevented from occurring in the occlusion process.
Preferably, a method for manufacturing a personalized abutment, in addition to the above steps, further comprises: acquiring a reference point position of a scanning rod, wherein the scanning rod is arranged in the oral cavity of a patient or a missing tooth in an oral cavity model in advance;
the method specifically comprises the following steps:
acquiring a reference point position of a scanning rod;
acquiring three-dimensional data in a patient mouth, wherein the three-dimensional data in the patient mouth comprises missing tooth and gum three-dimensional data and contralateral tooth three-dimensional data;
determining a gum contour, a gum penetrating height and a cuff shape according to the three-dimensional data of the missing gum, and determining an abutment height according to the three-dimensional data of the contralateral tooth;
generating personalized abutment three-dimensional data by combining the gingival contour, the transgingival height, the cuff form and the abutment height;
taking the reference point location as a datum point, adjusting the position of the three-dimensional data of the personalized base station, and adjusting the relative position between the reference point location and the three-dimensional data of the personalized base station;
and instantiating the individualized abutment according to the three-dimensional data of the individualized abutment after the position adjustment to obtain the individualized abutment, wherein the gum contour, the gum penetrating height, the cuff shape and the abutment height of the individualized abutment are matched with the three-dimensional data of the missing gum.
The scanning rod is arranged in advance at the missing tooth position in the oral cavity or the oral cavity model of the patient, the position of the implant is simulated through the scanning rod, then the reference point position of the scanning rod is used as a reference point, the position of the three-dimensional data of the personalized abutment is adjusted, and the reference point of the gingival contour, the gingival penetrating height, the cuff shape and the abutment height is determined more accurately, so that the personalized abutment can be better suitable for the specific patient.
Preferably, in the above step, there are two ways to obtain the personalized base station according to the instantiation of the three-dimensional data of the personalized base station, specifically: and converting the three-dimensional data of the personalized base station into the personalized base station through 3D printing or machine tool cutting.

When the personalized base station is manufactured, three-dimensional data in the mouth of a patient can be obtained through intraoral scanning or oral cavity model scanning. When the dental implant surgery is carried out, the intraoral scanner is arranged, intraoral scanning can be directly carried out through the intraoral scanner, and the image taking precision is improved. However, the cost of the intraoral scanner is too high, and when the intraoral scanner is not arranged during dental implantation, the intraoral scanner can acquire three-dimensional data in the mouth of a patient by manufacturing an oral cavity model and then performing three-dimensional scanning on the oral cavity model. The above two modes can be suitable for different application scenarios.
It should be noted that, the operator obtains the reference point position of the scanning rod and the three-dimensional data in the patient's mouth by scanning, and the system only needs to receive the data worn by the scanner; after the three-dimensional data of the reference point position and the patient mouth are obtained, the operator determines the gum contour, the gum penetrating height, the cuff shape and the abutment height in a targeted manner, the system only needs to receive the data input by the operator and integrates the data into the three-dimensional data of the personalized abutment according to the data, and the position of the three-dimensional data of the personalized abutment is adjusted; and finally, controlling 3D printing equipment or cutting equipment according to the three-dimensional data of the personalized base station after the position adjustment, and instantiating to obtain a real object of the personalized base station through 3D printing or machine tool cutting.
