Description
Technical Field
The invention relates to a planting auxiliary guiding device, which is applied to cases needing preoperative planning and accurate prediction of operation results, such as oral planting, repairing and the like; the method is particularly suitable for manufacturing the surgical guide plate for the case that the dental implant is implanted into the alveolar ridge top with sufficient height and the ridge top is sharp or uneven, and belongs to the field of oral medicine.
Background
In the oral clinical examination, patients with many missing teeth, sharp or uneven crest of the alveolar ridge are often encountered. At the moment, the dental implant osteotomy guide plate is manufactured, so that doctors can be helped to accurately perform alveolar bone crest trimming according to CBCT images, then the implant guide plate part is inserted to prepare implant pits, and in order to improve the implant accuracy and realize minimally invasive surgery, more and more doctors hope to adopt the implant surgery guided by the surgical guide plate in the field of oral medicine. However, in the case of a patient who needs to be implanted after the jawbone is cut, the procedure for manufacturing the surgical guide plate by the traditional method is very complicated, and two or more guide plates are needed. When the doctor operates, the doctor needs to wear the bone cutting guide plate, hit the fixing nail, take down the fixing nail and the bone cutting guide plate after bone cutting, wear the implanting guide plate and hit the fixing nail again. The method is a complicated, time-consuming and labor-consuming process, is used for testing physical strength and endurance of doctors, and simultaneously provides a severe requirement for the endurance of patients, so that the comfort of the patients during treatment is directly reduced.
In the prior art, a doctor usually needs to design an osteotomy guide plate with a retention pin sleeve, then repeats the previous process to design an implant guide plate, and only adds an implant sleeve and does not perform virtual osteotomy for the second time. After the doctor takes the bone cutting guide plate and the implanting guide plate, the doctor firstly cuts bones of the patient and then implants the bone, and the guide plate and the retention nails can be repeatedly taken and worn in the two processes. The operation steps are as follows:
1. scanning CBCT images and dentition STL surface data of a patient;
2. importing relevant data into oral implant design software, planning implant positions and retention pin positions;
3. designing a bone cutting guide plate;
4. designing a planting guide plate;
3.3D printing;
6. clinical trial wear and surgery.
The oral implant operation guide plate designed and prepared by adopting the traditional scheme has the defects that: in the manufacturing process, preoperative design and manufacturing work are complex, and a plurality of processes need to repeat the same operation; doctors have a lot of time to wear the retention nails and the guide plate, which results in low efficiency; the patient has long waiting period for completing the design, the operation time is long, and meanwhile, the traditional edentulous jaw guide plate is usually fixed by soft tissue, so that the guide plate needs to cover a soft group in a large area, the visual field is not clear during the operation, the flap turning space is small, and the operation is influenced because the cooling cannot be fully performed; in addition, the position of the prosthesis cannot be planned by the traditional guide plate, and the temporary prosthesis is usually manufactured on site after the implantation operation is finished, so that the treatment time of a patient is increased, and an accurate and convenient method is urgently needed to improve the dilemma of the case.
