Problems solved by technology

[0008] The disadvantages of the prior art data matching method are: the matching accuracy is not high, the operation time is very long, and even the possibility of matching failure may occur
[0018] The disadvantages of the guide plate for oral implant surgery designed and prepared by the traditional scheme are: in the production process, the preoperative design and production work is complicated, and many procedures need to repeat the same operation; doctors waste a lot of time on removing and wearing the retaining nails and the guide plate As a result, the efficiency is very low; the period for patients to wait for the design to be completed is long, and the operation time is also long

Embodiment 1

[0195] Such as Figures 2 to 6 As shown, a kind of anti-radiation material, the shape of the anti-radiation material 1 is a point (such as figure 2 shown), line (such as image 3 shown) or stripes, and set on the marking tape 2. The dot-shaped anti-reflection material is circular (such as figure 2 shown), rhombus (such as Figure 4 shown), rectangular (such as Figure 5 shown) or polygons (such as Figure 6 shown). The dot-shaped anti-reflection material is a single point (such as figure 2 shown), two points (such as Figure 4-6 shown) or a combination of multiple points. The marking tape is provided with a cutting line 3 (such as figure 2 , 4 , 5, 6). According to different packaging requirements and production strategies, the radio-blocking material can be packaged in rolls, single sheets or multi-sheets.

Embodiment 2

[0197] Such as Picture 1-1 Shown, a kind of preparation method of tooth-supported guide plate comprises the following steps:

[0198] a) bonding the radio-blocking material 1 on the tooth 4 (such as Figure 7 shown), bonding radiopaque material to gingival mucosa or / and bonding radiopaque material to other anatomical features; bonding at least 4 points on teeth, on gingival mucosa, or / and on other anatomical features radio-blocking material; other anatomical features include nasal ridge, mucosal inflection, bony prominence, lingual eminence;

[0199] b) Carry out CBCT shooting to obtain CBCT data with information of radio-blocking materials (such as Figure 8 shown);

[0200] c) Acquiring oral cavity surface STL data with radio-opaque material information, the method comprising:

[0201] i. Take an oral impression, and the radiation-resistant material will leave a mark on the corresponding position of the impression material. After the impression is hardened, reset the rad...

Embodiment 3

[0223] Such as Figures 12-1 to 12-4 , Figures 13-1 to 13-2 , Figures 14-1 to 14-2 , Figures 15-1 to 15-2 As shown, a tooth-supported guide plate prepared according to the preparation method of the tooth-supported guide plate in Example 2; includes a base guide plate 10, an implant guide plate 16, a restoration guide plate 19 and an in-position guide plate 13;

[0224] The base guide plate 10 is provided with a retaining nail sleeve 11 and a seating plane 12;

[0225] The planting guide plate 16 is provided with an implant sleeve 17, a retaining nail sleeve buckle 14, and a lingual seating plane 15; the retaining nail sleeve buckle 14 is buckled on the retaining nail sleeve 11 so that the The guide plate 16 is connected to the base guide plate 10; the lingual in-position plane 15 of the planting guide plate 16 is matched with the in-position plane 12 of the base guide plate 10;

[0226] The repair guide plate 19 is provided with a retaining nail sleeve buckle 14 and a l...

Abstract

The present invention relates to a tooth-supported guide plate, a mucosa-supported guide plate, a bone-supported guide plate and methods for preparing and using the same; wherein the preparation method of the tooth-supported guide plate includes: Bonding on the gingival mucosa or / and bonding radio-opaque materials to other anatomical features; b) CBCT shooting to obtain CBCT data with radio-opaque material information; c) acquisition of oral surface with radio-opaque material information STL data; d) match CBCT data with STL data; e) determine the position of the implant and retainer; f) generate the base guide; g) generate the in-situ guide; h) generate the implant guide; i) generate the restoration guide. The tooth-supported guide plate, the mucosa-supported guide plate, the bone-supported guide plate and the preparation and use methods thereof provided by the present invention can improve data matching accuracy and success rate, improve patient comfort, reduce the number of follow-up visits, and reduce clinical medical costs.

Description

technical field [0001] The invention relates to a tooth-supported guide plate, a mucosa-supported guide plate, a bone-supported guide plate and methods for preparing and using the same, and can be applied to marking when various X-rays, panoramas, and CBCTs are required for oral implantation, orthodontics, surgery, and restoration. , fields that require or do not need to integrate soft and hard tissue data at the same time; and applications in oral implants, restorations, etc. that require preoperative planning and accurate prediction of surgical results; especially suitable for oral implants with sufficient alveolar crest height The manufacture of surgical guides for sharp or uneven cases belongs to the field of stomatology. [0002] technical background [0003] In the dental field, in order to achieve the purpose of precise and minimally invasive surgery, guide plates are often used in implant surgery. At present, the production of guide plates must rely on three-dimension...
