Description

Cascading Oral Implant Surgery Guide System

technical field

The embodiment of the present invention relates to the technical field of surgical guide plates, and in particular to a cascading oral implant surgery guide plate system.

Background technique

With the continuous development of stomatology, the technology of oral implants to repair dentition defects/missing teeth has become more and more popular, and the demand for oral implant surgery is becoming more and more difficult to meet the growing needs of patients. After 2000, digital implant technology will become more and more mature, which will be an effective way to solve this problem. In particular, the popularization of CBCT will enable preoperative diagnosis and restoration based on patient CT image information and related restoration information, with the help of professional implant design software. Implant plan planning; through the dental implant surgery guidance template, the implantation plan formulated before the operation is accurately applied to the implant surgery and immediate restoration to assist the doctor to complete the treatment, which is called the dental implant surgery guide.

However, the previous dental implant surgery guide can only provide a single item of implant positioning or osteotomy positioning. If the above two operations need to be combined during the surgery, it is necessary to "wear-surgery-remove-replace-surgery", and in the "remove " and "replacement", it is very easy to cause the position shift caused by the damage of the positioning hole and the soft tissue edema and deformation to cause the inability to wear.

At present, there are many operations that need to be combined in oral implant surgery. At the same time, alveolar bone osteotomy, tooth/root extraction, bone augmentation surgery, maxillary sinus internal/external lifting surgery, temporary denture wearing surgery, etc. are often added. A single surgical guide cannot meet the needs of other additional surgeries. If the guide is replaced at each step, it cannot be guaranteed that the guide that only conforms to the oral state and environment before the operation can perfectly match the oral state and environment that have been changed by the previous operation. During the operation, the guide plate is replaced according to the needs. Every time the guide plate is replaced, the original position is maintained by the retention hole left in the jawbone when the original guide plate is retained. It will cause the retention hole to become larger and there will be tolerances, especially for patients with low osteoporosis density, such as patients with bone type three or four, it is completely unsuitable for such repeated insertion and extraction and fully digital navigation cutting. Multiple treatments such as bone, implant, and dental wear are concentrated under navigation and positioning. Secondly, every time the guide plate is replaced, it takes time to find the matching original retention holes, during which there may be three-dimensional deviations. Furthermore, the guide plate needs to be practiced repeatedly by the operator to complete the operation, which is unfavorable for beginners to use. Its four, existing guide plate can not guide the wearing of prosthesis on the same bone base guide plate.
