Embodiment Construction

[0019] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] A method for making an individualized bone fenestration guide for an impacted tooth, the steps of which are as follows:

[0021] S1. Patients with impacted teeth receive CBCT examination and accurately scan the teeth and gingival mucosa around the impacted teeth through an intraoral scanner;

[0022] S2. After accurate fitting of CBCT data and intraoral scanner data, three-dimensional reconstruction of oral soft and hard tissues is carried out, and an individual bone fenestration guide plan is designed;

[0023] S3. Transfer the scheme to the 3D printing machine for material reduction preparation;

[0024] S4. The individual bone fenestration guide plate was installed in the target area, and it was found that the bone fenestration guide plate fit perfectly with the teeth. The surgeon accurately exposed the embedded teeth through the con...

Abstract

The invention discloses a method for manufacturing an individualized bone fenestration guide plate for embedded teeth. The individualized bone fenestration guide plate for embedded teeth is prepared on the basis of an intraoral scanner and CBCT data by utilizing a 3D printing technology. The guide plate is made of a resin material, and the embedded tooth fenestration guide plate based on a tooth support type is printed through the 3D printing technology. The guide plate assembly performs positioning through teeth around the embedded teeth, is stable and does not loosen, and guarantees accuratepositioning.

Description

technical field [0001] The invention relates to a method for making an individualized bone fenestration guide plate for an impacted tooth. Background technique [0002] An impacted tooth refers to a tooth whose eruption period has passed, but the tooth has not erupted. Impacted tooth is a very common clinical oral disease, and it is easy to cause a series of complications, such as occlusal disorder, malocclusion, food impaction, etc. The common impacted teeth are maxillary canines. Currently, the best clinical treatment plan is to expose the impacted teeth through surgical fenestration, combined with orthodontic traction is the best treatment method. However, in the current surgical fenestration process, the blind method is often used based on the experience of doctors, which has the disadvantages of inaccurate positioning of fenestration, inaccurate amount of bone removal, large trauma, and high failure rate. At present, there is an urgent need for a technical solution th...
