specific Embodiment approach 1

[0041] (1) Specific implementation mode one: a kind of personalized abutment assembly, it is characterized in that: such as figure 1 As shown, it includes the abutment body 1, the fixing bolt 2 and the anti-loosening washer 3 connected between the implant and the abutment body 1, and the abutment body 1 includes a crown connection section 1-1, a gingival section 1-2 and the implant connection section 1-3, the abutment body is provided with a stepped hole that runs through the crown connection section 1-1, the gingival section 1-2 and the implant connection section 1-3, and the step One end of the hole located at the implant connection section 1-3 is a threaded hole 1-5 matching the fixing bolt 2, and the other end is a light hole 1-4 with a diameter slightly larger than the outer diameter of the bolt head 2-1 of the fixing bolt 2; The abutment angle α and abutment shape of the abutment body 1 are personalized abutments made according to the angle and shape of the patient's too...

specific Embodiment approach 2

[0052] (2) Embodiment 2: A method for preparing a personalized abutment assembly, characterized in that: the method includes sequential 3D scanning, CAD modeling, 3D printing and heat treatment;

[0053] The 3D scanning is to obtain the crown connection section 1-1, the gingival section 1-2 and the implant connection section of the abutment body 1 by scanning the plaster model of the patient's tooth with a 3D scanner or directly scanning the tooth in the patient's mouth 1-3 angle and shape information;

[0054] The CAD modeling is based on the data scanned by 3D software, combined with the tooth position and shape of the patient's affected teeth to design a personalized abutment that meets the requirements, and then performs three-dimensional slice processing on the designed personalized abutment, each layer The thickness is 10-50μm, and the processed data is stored in CL file format;

[0055] The 3D printing includes the following steps in order: ① input CL file; ② titanium-...

preparation example 1

[0061] Prepare personalized implant abutments according to the Zmmer implant system in the United States. First, use a 3D laser scanner to scan the plaster model in three dimensions, and obtain the shape of the abutment body, shoulder, denture connection, gingiva, and abutment angle from the plaster model. and other information; such as image 3 As shown, the interface of the abutment connection part is hexagonal, the abutment angle α is 3°, and the cone angle of the lower part of the abutment through the gingiva is 4°; then use Solidworks 3D software, according to the data obtained by scanning, combined with the patient's body The position and shape of the teeth are designed to meet the requirements of personalized abutments. The length of the implant connecting section is 2mm, and the inner side is provided with a thread with a pitch of 0.2mm; the thickness of the anti-loosening gasket is 0.2mm; the fixing bolts are fully threaded bolts with a pitch of 0.2mm; then the design...

Abstract

The invention relates to a customized abutment assembly and a preparation method thereof. The assembly comprises an abutment body, a fixed bolt connected between an implant body and the abutment body and an anti-loose pad, wherein the abutment body comprises a dental crown connecting section, a gum penetrating section and an implant body connecting section, and a stepped bore is formed in the abutment body; the abutment angle alpha and abutment shape of the abutment body are formed according to angles and shapes of a patient affected tooth and the implant body, so as to adapt to the angles and shapes of the patient affected tooth and the implant to obtain the customized abutment; the abutment angle alpha is the included angle between the center line of the dental crown connecting section and the center line of the implant body connecting section. The abutment assembly is formed by means of 3D (three-dimensional) scanning, CAD (computer aided design) modeling, 3D printing and thermal treatment, can sufficiently meet the customized requirements of different patients, and is advantageous to improve the aesthetic effect of teeth and better accords with physiological functions of teeth. Moreover, hospitals need not store massive products for clinical option, and the medical cost is furthest saved.

Description

technical field [0001] The invention relates to the technical field of biomedical engineering, in particular to a personalized abutment component and a preparation method thereof. Background technique [0002] Dental implant technology has become the mainstream technology of oral restoration due to its ideal supporting effect since it was applied clinically in the 1960s, and is favored by the majority of patients. However, for patients with high difficulty and high requirements for restoration, especially the anterior tooth area with poor local conditions in the implant area and high aesthetic requirements for the restoration, the finished abutments matched with the system can no longer meet the clinical needs. [0003] At present, the basic structure of most dental implant systems is mainly divided into three parts: implant, abutment and upper denture. An implant is a structure implanted in bone tissue, which acts as a natural tooth root to undertake functions such as supp...
