Manufacturing method of tooth implantation operation guide plate based on body image processing

Abstract

The invention discloses a manufacturing method of a tooth implantation operation guide plate based on body image processing. The manufacturing method of the tooth implantation operation guide plate based on body image processing includes the following steps: obtaining a plaster model of a tooth, scanning and generating a corresponding three-dimensional mesh model, and placing the three-dimensional mesh model into a stimulate implant through precision guidance according to a corresponding mouth cavity computed tomography (ct) model; sampling the three-dimensional mesh model of tooth gypsum and generating a corresponding body image; processing the body image and filling concave places in the teeth and extremely-narrow tooth slits; extracting the inner surface and the outer surface of an initial tooth guide plate; reading the position and the type of the implant, and generating an appropriate guide plate base table; defining a required guide plate range, taking out a tooth guide plate model, and obtaining the entity tooth implantation operation guide plate according to tooth guide plate model processing. The tooth implantation operation guide plate manufactured through the manufacturing method is capable of being successfully worn into the teeth, is not clamped, and meanwhile, can fit in with the teeth to the greatest extent, and is not prone to swaying when worn by a patient.

Description

technical field [0001] The invention belongs to the field of dental implants, and in particular relates to a method for manufacturing a dental implant surgery guide plate based on volume image processing. Background technique [0002] Dental implants refer to implanting artificial tooth roots into the alveolar bone, and then installing porcelain teeth on top of the artificial tooth roots, which are exactly the same as natural teeth in terms of function and appearance. Dental implant surgery includes preoperative examination, implantation of artificial tooth roots, installation of abutments, and installation of dental crowns. After the preoperative examination, the plaster model and CT data of the patient's teeth can be obtained. According to the CT data, the condition of the patient's teeth can be accurately understood, and a dental implant surgery plan can be formulated. In the dental implant surgery auxiliary software, the position of the implant can be correctly set acco...

Problems solved by technology

[0005] However, when generating the auxiliary guide plate for dental implant surgery, due to the complex shape of the human oral cavity, the auxiliary guide plate for dental implant surgery should not only be able to fit into the teeth smoothly without getting stuck, but also fit the teeth as closely as possible. No shaking, which requires a series of complex processing of patient oral data
