Description

Dental removal device

This model relates to a dental removal device, especially a dental removal device that is convenient to use, manufacture and quickly remove.

With the advancement and development of science and technology, the current technology and related equipment related to dental health care and treatment are also booming. In the process of dental health care and treatment, it is often necessary to use a water suction/high power suction. The patient’s saliva and washing fluid are pumped out to avoid leaving it in the patient’s mouth and affecting subsequent related operations. However, the existing saliva suction device is mainly made of plastic or metal with a rigid structure, which may not only affect the patient during the operation. The collision causes pain, and the hard structure cannot be adjusted according to requirements, which relatively limits the practicability of the existing saliva suction device.

Furthermore, the part related to dental implants has gradually become one of the indispensable life needs of people. During the process of implanting artificial tooth roots, according to the degree of atrophy of the patient’s gums, different amounts of powdered bone meal will be filled into the patient’s alveolar bone. Internally, the structure of the patient’s gums is repaired and reinforced to ensure that when the artificial tooth root is implanted in the patient’s gums, it can be firmly set on the patient’s alveolar bone; further, the current dental implant process requires treatment of the alveolar bone. Drill holes in order to set the artificial tooth root in the alveolar bone and fix it with the filling bone powder.

However, when a doctor drills a hole in the posterior area of the upper jaw, it is easy to drill the sinus membrane near the posterior area of the upper jaw. At this time, if the doctor does not notice that the sinus membrane is broken and fills the hole with bone meal , Will cause bone meal to enter the sinus cavity through the broken sinus membrane. Since there is no related technology to remove the bone meal that has fallen into the sinus cavity, it can only be expected that the bone meal may be discharged into the nasal cavity through the upper jaw sinus opening that communicates with the sinus cavity, but When the bone powder dropped from the sinus cavity cannot be smoothly discharged through the upper jaw sinus opening, the upper jaw sinus opening will be blocked by the bone powder, and infection and suppuration inside the sinus cavity will result in the upper jaw sinus infection. The germs spread into the brain, causing damage to the brain and affecting life safety. At this time, only otolaryngologists can perform functional endoscopic sinus surgery (Functional endoscopic sinus surgery; FESS) for treatment, which is quite unsafe for patients and is likely to cause medical disputes. Therefore, the current use of dental implants The technology and equipment used in bone meal can be improved.

Therefore, the creator of the new model, in view of the existing hard saliva suction and dental implants in the use of bone meal technology and equipment in the structure and use of the lack and insufficiency, especially after continuous research and testing, finally developed a method that can improve the existing The missing model.

The main purpose of the present invention is to provide a dental removal device, which can be quickly used with a hard saliva suction device through a simplified structural configuration, and can be used in the process of filling bone meal, if the bone meal is found to be damaged When the nasal sinus membrane enters the sinus cavity, the bone meal that enters can be removed by sucking to avoid the bone meal remaining in the sinus cavity causing subsequent infection and suppuration due to obstruction. It is relatively convenient to use and can avoid the patient’s subsequent need to face Those who can provide a dental removal device that is easy to use, manufacture and quickly remove due to the impact of surgery and life safety.
