Problems solved by technology

[0013] The defect of the prior art method for preparing surgical guides is that in the process of making the traditional tissue-supported surgical guides, the preparation work is quite complicated, and the patient needs to visit the doctor many times before the doctor can get all the required information, which virtually increases the number of patients. cost and radiation dose
At the same time, doctors also need to spend a lot of clinical time to prepare, which also affects the flow of cases
And all data sources are based on CBCT, and the accuracy of current CBCT equipment is mostly concentrated in the range of 0.2-0.5mm, which cannot fully meet the high-precision requirements of surgical guides

Embodiment 1

[0080] Such as Figure 1-9 Shown, a kind of surgical template preparation method, its steps are:

[0081] a) Adhesive radio-blocking material (such as figure 2 shown), and wear into the occlusal embankment; wearing the occlusal embankment can restore the ideal occlusal height and facial fullness of the patient; put special materials: various plastic materials, such as wax, various plastics, PEEK, silicone rubber, heat Sensitive material, resin, photosensitive resin, etc. but not limited to one, two or several of these materials alone or in combination to make the occlusal embankment, put this intelligent occlusal embankment into the mouth, wax may be used in this process Knife, carving knife, screwdriver, etc. If the occlusal height is not enough, spacers can be added on both sides or in the middle until the patient recovers the patient's ideal occlusal height, facial fullness, and temporal occlusal surface and joint comfort.

[0082] b) Carry out CBCT shooting (such as ...

Embodiment 2

[0093] Such as Figure 11 , 12-1 , shown in 12-2, 15-17, a kind of intelligent occlusal embankment, comprises the intelligent occlusal embankment of free shaping (such as Figure 11 shown) and spacers (as Figure 15-17 shown); Spacers are detachably attached to the smart occlusal embankment. Such as Figure 11 As shown, the intelligent occlusal embankment is provided with screw holes, and the gasket is provided with screw rods (such as Figure 12-1 , 15 As shown), the intelligent occlusal embankment and the spacer are fixedly connected through the screw hole and the screw rod. Such as Figure 12-2 As shown, the smart occlusal embankment and the spacer are provided with adhesive materials, and the intelligent occlusal embankment and the spacer are connected through the adhesive material. The intelligent occlusal embankment is prepared from one of the following materials or any combination of at least two materials: wax, plastic, PEEK, silicone rubber, heat-sensitive mate...

Embodiment 3

[0099] Such as Figure 8As shown, a surgical guide plate is composed of a guide plate main body and a guide ring, and the guide ring includes an implant guide ring 4 and a retaining pin guide ring 5 . The material of the main body of the guide plate is photosensitive resin, and the guide ring is a stainless steel metal guide ring. The appearance of the guide plate is smooth, the color is uniform, no scars, no scratches, and the edges are round and smooth. The minimum size of the guide plate is 30*20mm and the maximum is 100*100mm. The thickness of the guide plate is greater than or equal to 2.5mm.

Abstract

The invention relates to a surgical guide plate and a preparation method thereof, which is characterized in that it comprises the following steps: a) adhering a radio-blocking material on the oral mucosa and wearing it into the occlusal embankment; b) performing CBCT shooting to acquire radio-blocking material CBCT data of material information; c) Obtain oral surface STL data; d) Match CBCT data with STL data; e) Load occlusal embankment data; f) Intelligent teeth arrangement; g) Design implants and generate surgical guides. The surgical guide plate and its preparation method involved in the present invention can greatly improve the comfort of patients, reduce the preparation process, do not need to make radiation guide plates, reduce the number of follow-up visits, reduce clinical medical costs, improve the accuracy of the surgical guide plate, and reduce software. Design time to greatly improve the experience of seeing a doctor.

Description

technical field [0001] The invention relates to a surgical guide plate and a preparation method thereof, which can be applied to various operations such as oral implantation, orthodontics, surgery, restoration, etc., which require simultaneous integration of soft tissue data and convenient tooth arrangement. It is especially suitable for making surgical guide plates on implants, and belongs to the field of oral cavity. [0002] technical background [0003] Among oral clinical patients, patients with many missing teeth, poor bone quality and old age are often encountered. At this time, the production of tissue-supported surgical guides can greatly help the doctor to accurately position while causing minimal trauma to the patient. In the production process of traditional tissue-supported surgical guides, the preparation work is quite complicated. Patients need to make radiation guides (similar to the production process of removable dentures) and visit the doctor many times be...
