Description

Cyst stopper capable of maintaining interdental spaces

technical field

The utility model relates to the technical field of medical appliances, in particular to a cyst plugging device capable of maintaining interdental spaces.

Background technique

Odontogenic cyst of the jaw is a common benign tumor of the oral and maxillofacial region, which can occur in any part of the jaw, manifested as a painless resorption swelling of the jaw, resulting in swelling deformity of the surrounding facial soft tissue, tooth displacement and pathological Fractures, etc., are often treated surgically. Traditional cyst excision or curettage can easily damage the important anatomical structures around the operation, leave a large cavity after operation, and easily cause postoperative infection; while radical resection often leads to loss of bone continuity and functional loss and facial deformity. At present, the concepts of functional surgery and minimally invasive surgery are widely accepted. Various odontogenic cystic lesions can be treated with decompressive fenestration, also known as pouching. Due to the advantages of small trauma, important nerve and blood vessels can be preserved, and excessive tissue resection can be avoided, it has gradually been widely used in clinical practice.

Fenestration decompression devices include cyst stoppers, drainage tubes, etc. Among them, the cyst stopper is a special prosthesis used to prevent the premature closure of the cyst window, relieve the pressure in the cyst, and prevent food from entering the cyst cavity.
