Embodiment

[0039] Such as Figure 1-7 As shown, the manufacturing method of the gingiva forming and alveolar bone repairing operation guiding device of the present invention comprises the following steps:

[0040] S1: Obtain the patient's gum data and preset gum restoration data, and establish a digital model of the patient based on the patient's gum data;

[0041] S2: Excise excess gingiva in the digital model of the patient according to the preset gingiva repair data, and process the excised part to form a gingival contour; use the patient digital model that has been resected and processed as the initial digital model;

[0042] S3: constructing a tooth-supported retention device model covering the patient's gums and teeth on the digital primary model;

[0043] S4: Excise the coronal part of the tooth-supported retention device model along the contour of the formed gingiva to form a gingiva forming guiding arc surface 3;

[0044] S5: Establish the alveolar bone repair guiding arc surf...

Abstract

The invention discloses a production method of a gingiva forming and alveolar bone trimming surgery guiding device. The production method of the gingiva forming and alveolar bone trimming surgery guiding device comprises the following steps: building a digital patient model; cutting redundant gingiva in the digital patient model, and forming a formed gingiva contour; building a tooth-supporting retention device model; forming a gingiva forming guiding cambered surface; building an alveolar bone repair guiding cambered surface, and cutting a root side portion along the alveolar bone repair guiding cambered surface; and generating the guiding device. The gingiva forming and alveolar bone trimming surgery guiding device is further disclosed. According to the production method of the gingiva forming and alveolar bone trimming surgery guiding device and the guiding device, the surgery guiding device which conducts gingiva engraving forming in a computer, and then conducts modelling and 3D printing is provided, gingiva forming surgery and alveolar bone trimming surgery are guided through the device, and by combining digital design and 3D printing, a novel tooth preparation surgery guideplate is produced, so that a clinical tooth preparation surgery process is guided.

Description

technical field [0001] The invention relates to dental aesthetic surgery technology, in particular to a manufacturing method and a guiding device for gingiva molding and alveolar bone modification surgery. Background technique [0002] The shape and contour of the gums are an important part of dental aesthetics, and more and more patients pay attention to parts other than teeth such as gums. The gums are too low, resulting in too much gum exposure when smiling, and insufficient exposure of the crown, which is a major indication for gingivoplasty at present. At the same time, the periodontal biological width of 2.04mm also puts forward requirements for the mutual position of the alveolar bone and the gums, that is, the distance from the junctional epithelium of the gums to the top of the alveolar ridge is about 2.04mm, if it is insufficient, there will be periodontal disease risk, leading to inflammation, alveolar bone resorption, periodontal ligament damage, etc. Therefore,...
