Intraoral cyst post-fenestration maintaining device and manufacturing method thereof

Abstract

The invention discloses an intraoral cyst post-fenestration maintaining device and a manufacturing method thereof. The maintaining device comprises a cyst cavity external fixation body and a soft drainage tube. The cyst cavity external fixation body is matched with soft and hard tissue on the periphery of a cyst windowing area, and the top end of the cyst cavity external fixation body is flush with the top end of molar teeth. One end of the soft drainage tube is connected with the cyst cavity external fixation body and is matched with and corresponds to the cyst windowing portion in shape. The cyst cavity external fixation body is formed by combining a soft layer and a hard layer, the inner soft layer can avoid pressing pain, and the wearing comfort is improved; the outer hard layer plays a role in maintaining the shape and ensuring the strength. Due to the drainage tube with the sterile hose as a stretching-in portion, the effect of preventing the windowing portion soft tissue from healing can be achieved, and meanwhile the phenomenon that food residues fall into the cyst cavity in the feeding process is avoided. The maintaining device prevents post-operation soft tissue from healing, maintains the cyst cavity to be open, avoids exogenous infection, and meanwhile has the advantages of being comfortable to wear and use, not affecting language and feeding, and the like.

Description

technical field [0001] The invention relates to a medical device, in particular to a maintenance device for oral and maxillofacial cysts after fenestration, which is used for maintenance after fenestration of oral and maxillofacial keratotic cysts or ameloblastoma, and belongs to the occluder nursing device. Background technique [0002] Various odontogenic and non-odontogenic cysts are common diseases that occur in the jaw. For cysts that occur in the jaw, common treatments include decompressive fenestration. Fenestration decompression is to open the bone and cystic wall on the surface of the cystic lesion in the first-stage operation, or the cystic wall can be removed as much as possible. Then keep the wound open, on the one hand to play the role of drainage, on the other hand to make the pressure inside the lesion the same as the outside world. Under the stimulation of normal functional activities, a large amount of new bone will form around the cyst, and the cyst will ...

AI Technical Summary

Problems solved by technology

If the cyst wound is located in the dentition area, a removable denture occluder can be used; but when the cyst wound is located in the upper and lower vestibular grooves, retromolar pads, etc., the removable denture occluder cannot be worn

[0005] If the method of filling the iodoform gauze in the cyst cavity is used, there are the following problems: first, the patient needs to take out the iodoform gauze by himself every day, rinse the cyst cavity, and then insert the iodoform gauze back into the cyst cavity, which is a complicated process And bring pain to the patient; the second, the incomplete cleaning of packing materials such as iodoform gauze can cause the infection of cystic cavity; the 3rd, when the cystic cavity is bigger, packing material often can be transferred into the inside of cystic cavity, can't take out Fourth, the tamponade cannot effectively organize the healing of the soft tissue on the surface of the wound
