Problems solved by technology

However, due to the laborious and laborious carving of the wax-up, and the connection position between the abutment and the implant needs to be transferred through the impression, the personalized abutment designed in this way cannot guarantee the precise connection with the abutment

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] First refer to Figure 7 Shown, the present invention comprises the steps:

[0028] Step 1. Data collection and preprocessing: After the implant is integrated with the surrounding bone tissue, a second operation is performed to select a suitable healing abutment and install it on the implant. Such as figure 1 As shown, in order to ensure the accuracy of subsequent measurements, it is required that the installed healing abutment must be more than 1mm higher than the gingival soft tissue. After the gums healed, an impression was taken to make a plaster model of the upper and lower jaws, and then a scanner was used to collect data on the plaster model. Due to the unavoidable defects such as noise and scanning blind spots in the scan, the collected data is preprocessed, and the data preprocessing includes noise, triangulation, ...

Abstract

The invention discloses an implant denture individual abutment design method based on a healing abutment dental model, and belongs to the field of computer auxiliary design. The method comprises the following four steps: acquiring and preprocessing data; establishing an implant system model base; positioning a healing abutment and an implant body; and designing an individual abutment. The implantdenture individual abutment design method is high in automation, not only ensures that the operation steps of manufacturing a wax pattern or casting a model, and transferring the implant body on clinic and the like can be omitted, but also can be used for improving the shape of gingival margin of the restored implant denture, greatly reducing the operation time and cost of a doctor and a skilled work, and improving the restoration efficiency and beautiful appearance; the implant denture individual abutment design method based on the healing abutment dental model has important application value in a computer auxiliary dental implant field.

Description

technical field [0001] The invention relates to a design method for a personalized abutment for denture implantation, which belongs to the field of computer-aided design, and relates to the fields of reverse engineering and biomedical engineering. Background technique [0002] Dental Implant Technology is a method that uses artificial implants to be placed in the alveolar bone to complete the restoration of missing teeth. Because it has a very ideal retention and support effect, and it is comfortable and beautiful, and there is no need to grind the adjacent natural teeth, it is favored by patients with missing teeth. Since the neck shape of the existing implant and gingival healing abutment is cylindrical, rather than the irregular shape of the natural tooth neck, and the diameter of the healing abutment is thinner than the diameter of the natural tooth neck, it is made on this basis The neck of the denture porcelain crown can only be approximately round, the cervical margi...
