The invention relates to a dental support guide plate, a mucosal support guide plate, a bone support guide plate and preparation and use method thereof, which can be applied to oral implant, orthodontic surgery, repair and so on needs to all kinds of X light, the mark of the CBCT, need or not need to integrate the field of soft and hard tissue data; and applying to oral implant, repairing and so on need pre-operative planning, accurately predicting the case of the surgical result; It is especially suitable for oral implant to implant alveolar ridge top height fully, manufacturing of surgical guide plate with sharp or uneven ridge, belonging to the medical field of oral cavity.
In the oral cavity field, in order to reach the purpose of precise minimally invasive surgery, the guide plate is used in the planting operation, the manufacturing of the guide plate must be by means of three-dimensional CT or cone-beam scanning CT (CBCT for short). Due to CBCT application limitation, CBCT can only obtain relatively clear jaw bone, tooth body and other hard tissue information (the patent uses CBCT to obtain CBCT data for short), but cannot obtain the soft tissue information with high precision. In general, clinical will use high precision oral surface scanning device for fine scanning oral tissue surface, to obtain the dental tissue and soft tissue information (hereinafter referred to as STL data). Because the CBCT data and STL data contain tooth tissue information, through matching the two data of the tooth tissue information, the CBCT data and STL data can be integrated together, so as to present the bone information of the patient, tooth information and soft tissue information. However, when the oral cavity remaining tooth is not too many, it is difficult to adopt the method, and will adopt more complex method for manufacturing the radiation guide plate to obtain clear soft tissue information and repair information.
In the prior art, when matching the data, if using the oral surface scanning device matching method, the operator manually using software at the same tooth position selecting the corresponding point to match, the method needs to be judged by naked eyes, comprising the following steps:
1. The oral surface scanning device of the oral cavity scanning data information of the patient oral surface scanning device:
2nd, obtaining CBCT data information of patient;
3rd, manually selecting similar position points to match in the software.
The defects of the prior art data matching method are as follows: the matching precision is not high, the operation time is long, even the possibility of matching failure happened. when the oral cavity remaining tooth is not too many, the radiation guide plate method is used for matching; the patient needs to be diagnosed for many times; the radiation guide plate (similar to the product of the movable denture) is prepared in advance; then the shooting of the CBCT is carried out; the patient cost and radiation dose increased in the intangible; and time and workload of the case are increased; so that the whole process is very complex.
In addition, in the oral clinical diagnosis, often encountered loss of tooth, alveolar ridge sharp or uneven patient. At this time, manufacturing the oral implant osteotomy guide plate can help the doctor to accurately trim the alveolar bone ridge according to the CBCT image; then inserting the planting guide plate part; preparing the planting nest hole. In the manufacturing process of the traditional oral implant osteotomy guide plate, the manufacturing process is complicated; the design and manufacturing period is long; the patient most time is in the waiting state; and when the operation needs to repeatedly pick the guide plate, seriously affecting the patient diagnosis experience and high efficiency of the doctor treatment. the traditional method part also adopts manual operation method; the difficulty is large; the threshold is high; suitable for few people; the new oral implant guide plate provided by the invention completely meets the requirement of the surgical guide plate; it not only greatly reduces the difficulty of the doctor for osteotomy, planting and repairing surgery, and diagnosis cost of the patient is also reduced.
In order to improve the planting precision, realizing minimally invasive surgery; in the oral medicine field, more and more doctors want to use surgical guide to guide the planting operation. and wherein, when encountering the need to the jaw bone after re-planting case, using the traditional method for manufacturing operation guide flow is very complex, needing two or more guide plate. When the doctor operates, it needs to wear the osteotomy guide plate firstly, strike the fixing nail, after the osteotomy, take the lower fixing nail and osteotomy guide plate, and then wear the planting guide plate, and again strike the fixing nail. This is a fussy, time-consuming and labor-consuming process. It is a test of physical strength and endurance of the doctor; at the same time, it also provides a severe requirement for the stress tolerance of the patient, and directly reduces the patient's comfort.
In the conventional technology, the doctor generally needs to design a bone-cutting guide plate containing fixing nail sleeve, then repeating the last flow design a planting guide plate, but only the second time to add the implant sleeve and does not carry out virtual osteotomy. After the doctor gets the osteotomy guide plate and planting guide plate, the patient firstly performs the osteotomy, then planting, the two processes will repeatedly take the guide plate and fixing nail. The operation steps are as follows:
1st, scanning the CBCT image and dentition STL surface data for the patient;
2nd, introducing the related data in the oral implant design software; planning the implant position; fixing the position of the nail;
3rd, designing osteotomy guide plate;
4th, designing the planting guide plate;
5th, printing by @3 D;
6. Clinical try-on and surgery.
using the traditional scheme design, the preparation of oral implant surgery guide defect is: In the manufacturing process, the preoperative design, manufacturing work is complicated, many processes need to repeat the same operation; the doctor has a lot of time waste on picking and fixing nail; on the guide plate, the efficiency is low; the patient waiting for the designed period is long and operation time is long.
The invention claims a tooth supporting guide plate, a mucosa supporting guide plate; The invention claims a bone support type guide plate and preparation and use method thereof, wherein the CBCT data and STL data containing the barrier material information are obtained by adding the barrier material at the corresponding position, and CBCT data and STL data can be accurately matched only by matching the barrier material information in the two; it can greatly improve the matching precision of CBCT data and STL data, improve the comfort of the patient, reduce the diagnosis times, reduce the clinical medical cost, reduce the difficulty of integrating the two data, especially when there are more teeth, it is convenient and easy to manufacture. In addition, the guide plate provided by the invention makes the osteotomy, planting and repairing on a guide plate sleeve can be realized. optimizing the design process, no need to make osteotomy guide plate, planting guide plate, so as to overcome the traditional method needs to repeatedly take the defect of the fixing nail and guide plate, reduces the clinical medical cost and improves the surgical precision, patient diagnosis experience also rises a layer.
