Description

A negative pressure device attached to dental tissue

technical field

The utility model relates to the field of medical equipment, more specifically the utility model relates to a negative pressure device attached to tooth tissue, which is used for clinical treatment of odontogenic non-infectious and infectious diseases, and can be used in ameloblasts Tumor, odontogenic jaw cyst, pulpitis, periapical periodontitis, periapical cyst, periapical abscess, periapical granuloma and other diseases.

Background technique

At present, decompression and drainage are mostly used in the clinical treatment of odontogenic diseases such as ameloblastoma and odontogenic jaw cyst. Open drainage is usually used for periapical granuloma. Clinical evidence-based medicine and scientific experiments have proved that these treatments have good curative effect. The purpose of decompression or open drainage is to make a channel for local inflammation, release pressure and relieve pain. And local damage, reduce the pressure in the cyst cavity, after the pressure is eliminated, new bone will form around the lesion area, and the cyst cavity will shrink, so as to preserve the anatomical structure of the jaw and teeth, reduce surgical trauma, and reduce the recurrence rate. However, this will lead to many follow-up problems, such as the long treatment period of decompression and drainage currently used clinically, which increases the chance of postoperative cyst infection, and the gums are easy to grow into the drainage port, requiring a second fenestration operation; while open drainage will Bringing such as oral saliva, food debris, various oral microorganisms and infected tissues into the open pulp cavity and even the periapical period may lead to more serious inflammation and infection. Therefore, how to shorten the treatment cycle, reduce the chance of infection, and reduce traumatic treatment has become a research hotspot. The jawbone is the most active part of the human body. When encountering pressure, it will activate osteoclasts, resulting in bone resorption; while encountering tension, it will activate osteoblasts, leading to the process of osteogenesis. The principle of negative pressure is similar to this, which can Changing the hydrostatic pressure of apical inflammation or jaw cyst cavity to negative pressure stress, the expansion and growth factors of the lesion caused by the hydrostatic pressure in the cyst cavity will be eliminated, and the bone tissue will grow in the direction of the cyst cavity, thereby shortening the course of the disease, and at the same time Reduced infection. With the advancement of science and technology and medical equipment, the utility model combines material science and biomechanics to invent a negative pressure device attached to the hard tissue of the tooth. Through the apical hole structure of the tooth tissue itself, both It can drain and form negative pressure in the cystic cavity, and at the same time, it is no longer necessary to implant artificial devices for negative pressure drainage in the jaw bone for a long time, which can greatly shorten the treatment cycle, reduce the chance of infection, reduce trauma and discomfort in the mouth, and improve the treatment efficiency. The clinical efficacy of odontogenic related diseases, and achieved very good results in practice.
