Embodiment 1

[0059] like figure 1 As shown, the present embodiment 1 provides a method for making a post-core plastic repair guide for a single right upper central incisor residual crown, including the following steps:

[0060] A1. Use the 3ShapeTRIOS scanner to scan the upper and lower jaws to obtain data in Stl format of the upper and lower jaws, and import the data in Stl format of the upper and lower jaws into 3shapedentalsystem to obtain a digital model of the upper and lower jaws;

[0061] Use Morita CBCT to scan the patient's jaw to obtain data in DICOM format, and import the data in DICOM format of the jaw into 3ShapeImplantStudio software to obtain a CBCT jaw model;

[0062] A2. Adjust the digital model of the upper and lower jaws based on the arrangement of the teeth, the shape of the adjacent teeth and the occlusal relationship of the upper and lower jaws, and obtain the digital model of crown restoration;

[0063] A3. The above-mentioned digital model of crown restoration is r...

Embodiment 2

[0090] The present embodiment 2 provides a manufacturing method for a post-core plastic repair guide plate for multiple upper anterior teeth residual roots. The difference from the embodiment 1 is that the post and core plastic repair guide plate 1 is not provided with a reinforcing rod 8. A cut-off line is set in the digital model of the guide plate, and the above-mentioned digital model of the guide plate is cut off from the cut-off line to form two digital models of the guide plate, which is convenient for the insertion and removal of the post-core shaping repair guide plate 1 .

Embodiment 3

[0092] like Figure 2 to Figure 5 As shown, this embodiment 3 is a post-core plastic repair guide for residual root and residual crown made by the manufacturing method of embodiment 1, including a guide plate main body, and the above-mentioned guide plate main body includes a resin core forming cavity 2, and the above-mentioned resin core forming cavity 2 is pre- There is room for crown restoration.

[0093] The above-mentioned resin core molding cavity 2 is a pre-designed full-crown restoration 4, which is reduced on the basis of the full-crown restoration 4 to form a resin core, and the axial position and size of the resin core are determined based on the optimal restoration effect of the crown. and shape, and the designed resin core molding cavity 2 reserves enough space for the crown restoration, which is convenient for crown restoration; when using the post and core shaping restoration guide 1, the above post and core shaping restoration guide 1 is provided with a resin c...

Abstract

The invention discloses a manufacturing method and a guide plate for post-core shaping and repairing of residual root and residual crown, and relates to the technical field of oral auxiliary medical equipment and preparation thereof. The method includes: A1. Model and CBCT jaw model; A2. Adjust the digital model of the upper and lower jaws to obtain a digital model of crown restoration; A3. Reduce the digital model of crown restoration according to a predetermined value to obtain a digital model of resin core; A4. Register the digital model of resin core and CBCT For the jaw model, obtain the digital model of the post and core shaping repair guide; A5. Make the digital model of the post and core shaping repair guide into an entity; first obtain the full crown restoration after crown restoration, and then proceed with the full crown restoration as the guide. Reduce and obtain a digital model of the resin core, which not only reserves enough space for crown restoration, but also reduces the waste of resin materials and the time for clinicians to trim the resin core.

Description

technical field [0001] The invention relates to the technical field of oral auxiliary medical equipment and its preparation, in particular to a method for manufacturing a guide plate for shaping and repairing a post and core of residual root and residual crown and the guide plate. Background technique [0002] In oral clinical restoration, residual root and residual crown are common dental defects. Some residual roots and residual crowns cannot be repaired and retained due to the large defect range, and need to be removed. For the residual roots and crowns that can be preserved, post-core crowns can be used for restoration after complete root canal treatment. Post-core crown restoration mainly includes three parts: post, core, and crown. The post is the part inserted into the root canal, which is bonded to the root by adhesive. There are three main types: finished fiber post and personalized cast metal post And personalized cutting zirconia all-ceramic post; the core is th...
