Abstract

This invention relates to the field of medicine, namely to surgical dentistry. The aim of the invention is to improve the fixation of the prosthesis on the lower jaw. Postata migrated to the defect stalked flap cut out triangular skin-fat flaps, then move the defect of the mucous membrane of the vestibule of the mouth in the lower arch. A positive effect is evaluated by an improvement in functional results.

Description

The invention relates to medicine, namely to surgical dentistry, and can be used in the elimination of defects of the chin.

The aim of the invention is to improve the fixation of the prosthesis on the lower jaw.

The method is carried out as follows.

To the defect of the chin, the moss stitches are stitched according to the method of Parin. Then a cut is made along the transition fold of the arch of the lead-in. 3-4 cm, the tissues are displaced downwards, the fragments of the lower jaw remain covered by the periosteum. A p-znea forms a triangular surface, the apex of which faces distal. Next, the incision is continued along the scar of the mucous membrane and skin in the area of the chin defect. On the inner surface of the stem stem from the end of the incision made along the transition fold, they cut out a triangular skin-fat flap with apex to the middle part of the stem, according to the size of the corresponding wound surface of the vestibule.

The stalk is dissected from below, the skin-fat flaps rotac5 are transferred to the wound area of the vestibule and fixed with sutures. The edge of the stem dissected from below is closed with the mucous membrane of the floor of the mouth and the skin of the chin. The following possible operations depend on the shape and size of the defect, the need to form the red border of the lips, etc.

Example. Sick M-VA, 30 years old, was admitted to the dental department of the Regional Clinical Hospital N ° 1 with a post-gun chin defect on June 2, 1986. There is a through defect in the bone section from 41 to 4 (soft and soft chin tissues. Fragments are mobile. Transitional fold in the area 4 4 is almost completely absent due to changes, partially preserved in 515. Under local anesthesia with a 0.5% solution of novocaine (500 ml), a stalked flap of Filatov on the lateral surface of the abdomen measuring 12X20 cm is prepared. Healing by primary tension.

Psechena from the abdomen and moved to the de- ect of tissues on the right, the leg is sutured according to Pa-1in. 11/25/86. The stem of the stem is cut off from the tissue and moved to the tissue defect: the left, the stem of the stem is stitched along the Parin. Healing at the stages of the operation is primary tension. Discharged to an outpatient-liioe treatment on 12/18/86. Re-admitted to the hospital was made on 02/05/87. On 11/02/87, under local anesthesia, the oral cavity was formed in 654 (456 and the partial spreading of the stalked forest. For this, the scars were cut through the transitional fold in 54145 and the mucous membrane in 615, the tissues are displaced downwards, fragments of the 1 jaw are covered with periosteum, the incisions are extended under the stem legs, where two triangular skin grafts 3X3 cm wide and wide are cut out) 2.5 cm at the base. The flaps are spread out on a plane and laid in well} area of the vestibule of the oral cavity, the seams 5ashvayut nylon. The cuts 10 are continued to the lower edge of the stem and along the scar at the border of the skin and mucous membrane in the region of the floor of the mouth. The skin and mucous membrane are sutured with the skin of the stem. Healing by primary tension.

The proposed method has the following advantages; the cicatricial deformity of the lower arch of the vestibule is eliminated, which makes the soft tissues more mobile, the vestibule of the oral cavity is formed, which creates conditions for more effective fixation of the denture on the lower jaw, the probability of necrosis of the stalked flap during its spreading is reduced increasing the area of the legs and stitching it to the defect along its entire length; no prosthesis is required before the operation, which forms the threshold of the oral cavity.
