Personalized positioning navigation system for dental implantation

Abstract

The invention discloses a personalized positioning navigation system for dental implantation, which comprises a digital buccal working model with a schematic implant, a positioning guide plate model designed according to the digital buccal working model, and a positioning guide tube matched with the positioning guide plate model, wherein the positioning guide plate model comprises a T-shaped platform structure, and the left side and the right side of the T-shaped platform structure are provided with a support surface jointed with the tooth crown surface of an adjacent tooth or the alveolar bone surface of an adjacent toothless area; and the T-shaped platform structure comprises a platform part and a guide tube part, wherein the positioning guide tube with a T-shaped structure is placed in the guide tube part. The precise match of the digital buccal working model of the implant and a personalized positioning guide plate ensures that the real implant is implanted at the position of the graphic design after the navigation and positioning of the personalized positioning guide plate in the operation, thereby greatly improving the success rate of the dental implantation.

Description

technical field [0001] The invention relates to the field of oral implantology, in particular to a personalized positioning and navigation system for dental implant surgery. Background technique [0002] Dental Implantology is an independent emerging branch developed in the 1930s, mainly including implant surgery, implant denture restoration, implant materials, implant mechanics and implant biology. Among them, the implants that play a role in support and retention are called oral implants, usually also called dental implants, which refer to the design of implanting artificial materials in the upper jaw or mandibular jaw by surgical means in order to support the upper structure of denture restoration. s installation. Implants are divided into intraosseous implants, subperiosteal implants, intradental intraosseous implants, intramucosal implants, transmandibular implants, and mandibular ramus implants according to the implantation site. So far, intraosseous implants are mai...

Problems solved by technology

If you want to fully grasp the correct direction and position of the implant from these plane pictures, you need the operator to have quite a lot of experience, so the probability of success will be relatively high, and even if it is an implant mastered by an experienced operator The direction and position of the implantation are only a guessed position obtained visually, in the imagination of the human brain or after simple measurement, and the accuracy is still relatively low. At the same time, due to the limitation of the body position and the operation space during the operation, the predicted position is different from the actual position. The position and direction of implantation are prone to deviation

Once the implant fails, it will not only bring more pain to the patient, but also bring a lot of property loss to the patient. After all, so far, the cost of implant surgery in China is still relatively expensive. The average cost of implanting a tooth is about 1 around 10,000 yuan
