Description

Dental implant instrument set and sinus scraper for vertically moving the mucosa of the sinus cavity to form a bone space

This creation is related to a dental implant instrument set including sinus scrapers, especially a dental implant instrument set for vertical movement of the sinus cavity mucosa to form a bone space. It uses a bone drill from the artificial tooth root to be implanted. The teeth are drilled upward toward the alveolar bone to expose the sinus cavity mucosa, and the exposed sinus cavity mucosa is peeled off with a sinus scraper and moved inward to form a bone space above the missing tooth.

In recent years, with the rapid development of dental implant technology, artificial dental implants have gradually replaced the traditional treatment of missing teeth and become the mainstream. Artificial dental implant system is to surgically implant the implant in the missing tooth area of the alveolar bone as an artificial tooth root. After the implant and the alveolar bone are tightly combined, the upper tooth is placed on the implant base crown. Because the implant system is deeply implanted in the alveolar bone and is tightly integrated with the alveolar bone, its strength is sufficient for normal chewing, and it is comparable to natural teeth in terms of function and appearance.

As mentioned above, because the implant is deeply implanted in the alveolar bone and is tightly integrated with the alveolar bone, if the condition of the alveolar bone is not good (such as alveolar bone atrophy), the implanted artificial tooth root will be caused Part of it is exposed, and it is difficult to tightly integrate with the alveolar bone, which will easily lead to failure of the implant surgery. Therefore, before performing dental implant surgery, it is necessary to evaluate the condition of the alveolar bone at the missing tooth to determine whether or not a bone replacement is needed.

The psoralen is performed by conventional side-window sinus augmentation surgery. Please refer to Figure 3 and Figures 5A to 5B. Figure 3 is a schematic cross-sectional view showing the physiological structure of the upper jaw, which shows the relative positions of teeth A1, alveolar bone A2, gingiva A3, sinus cavity A4, and sinus cavity mucosa A5. Figures 5A to 5B are schematic diagrams showing the conventional side-window sinus augmentation surgery, which is performed from the outer gingiva of the missing tooth. During implementation, as shown in Figure 5A, first cut the outer gingival flap A30 at the missing tooth and open it to expose the alveolar bone A2 under the gingival flap A30. Subsequently, as shown in Figure 5B, a bone hole A6 is drilled for the exposed alveolar bone A2 with a bone drill to expose the sinus cavity mucosa A5 below it. Finally, the exposed sinus cavity mucosa and alveolar bone are peeled off with appropriate equipment and pushed inward to form a bony space where bone powder is placed for bony bony use.

In view of the poor condition of the alveolar bone in the missing tooth, although there is a conventional method of repairing the bone using the side window sinus augmentation surgery, because it is performed from the outer gingiva of the missing tooth, the wound area required to be created is larger. , And it is easy for the patient to have a stronger sense of discomfort, which also increases the complexity of the operation.
