Indications for a cystectomy of the tooth

Cystectomy is a surgicalOperation, in which the cyst shell is completely removed, and then the wound is sutured. Such a surgical intervention is performed in the following cases: with a cyst, which is a malformation of the odontogenic epithelium, with a cyst that is small in size and located in the jaw region within 1-2 teeth, with an extensive cyst of the lower jaw, in which there are no teeth in its area, cyst of large size on the upper jaw, which does not have teeth in this area, with a cyst adjacent to the maxillary sinus or pushing it away (without symptoms of sinus inflammation). The operation involves the removal of education, and, zhnosti, maintaining the adjacent teeth, which were the cause of its occurrence. In this case, single-root teeth, which provoked the development of the cyst, are sealed, leaving the material behind the top of the root. When the formation is close to the neck, keeping the tooth is impractical, since after resection of a part of the root and apex its remainder does not stand the load and is loosened. Multiple root teeth can not be retained because of the obstruction of the canals, and they are removed. Teeth, which are the causes of the development of a tooth-containing cyst, are removed in all cases.

How do cystectomy of the tooth

Cystectomy is performed under infiltration andConductive anesthesia. On the surface of the alveolar process of the jaw, a mucosal-periosteal flap is cut to the bone by means of a cut of the mucous membrane. It should not reach the edge of the gum by 0.5-0.7 cm. If a tooth extraction is planned, the incision should pass through its socket. When the cyst is located close to the neck of the tooth, a gingival margin should be included in the flap, containing the dentogingival papillae. The size of the flap should be larger than the cyst. Then the mucus-periosteal flap exfoliate from the bone. The holes are drilled over the cyst along the perimeter of the future defect. The resulting bone plate is removed, exposing the front wall of the formation. Peel off the cyst shell, connected with the root of the causative tooth. To separate it, the root tip is cut to the bone level. The cyst is extracted together with the root. After resection of the apex of the root, the remains of the membrane are scraped to prevent relapse. After this, an audit of the bone cavity is performed, pieces of filling material are removed. Then the flap is put in place, the edges of the wound are sutured. Outwardly, a special bandage "mouse" is applied to limit the movements of the cheeks and lips and create a rest for the operated area no less than 4-5 days. The patient is prescribed painkillers, carries out anti-inflammatory therapy.
