Problems solved by technology

[0004] At present, doctors usually perform maxillary sinus lifting surgery blindly. When the osteotome is piercing the sinus floor bone, whether the last layer of bone tissue is broken depends on the sense of void felt by the doctor. Whether the mucosa is damaged is not easy to be found. The risk of the bottom mucosa is high, once the sinus bottom mucosa is broken, it is difficult to salvage

Abstract

The embodiment of the invention provides a maxillary sinus lifting tool, and relates to the technical field of oral medical instruments. Actual pressure borne by a working section is collected through a pressure detection element, so that a controller can judge whether the actual pressure meets a preset condition or not after the actual pressure is obtained; if the preset condition is met, the last layer of bone tissue of the sinus floor bone is chiseled through the working section, so that the controller sends out a starting signal at the moment to enable an alarm device to send out an alarm prompt; and a doctor can clearly know that the sinus floor bone is chiseled through according to the alarm prompt sent by the alarm device, the doctor can immediately stop the chiseling operation, and the fragile sinus floor mucous membrane is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of oral medical instruments, in particular to a maxillary sinus lifting tool. Background technique [0002] At present, dental implants have become the preferred restoration method for more and more patients with missing teeth. However, patients with missing teeth in the maxillary posterior region often have insufficient residual bone due to the low position of the maxillary sinus, severe alveolar bone resorption, and atrophy. Penetration into the maxillary sinus can cause complications such as infection. Therefore, the existence of the maxillary sinus is a major obstacle for implantation in the maxillary posterior region. [0003] Maxillary sinus lifting is currently a common method to solve the lack of bone in the maxillary posterior region. The implant hole is mainly prepared through the alveolar crest. When the preparation is close to the sinus bottom, a special osteotome is used to push the sinus bott...
