Surgical method for repairing anatomical shape of alveolar process of a jaw

FIELD: medicine.

SUBSTANCE: method involves shaping bone portion of alveolar process using bores and separation disks after cutting out mucoperiosteal flap having greater size then defect has, throwing out flap from exposed bone and making mobilization. Alveolar process bone plates are bluntly broken. Transplant is placed on the alveolar process, surrounded with bone plates in sandwich manner, strengthened with mucoperiosteal flap and sutured with interrupted sutures.

EFFECT: high reliability in repairing anatomical shape.

 

The invention relates to medicine, namely to dentistry. The proposed method can be used to correct defects of the alveolar ridge in vestibular-oral direction for fixed dentures for cosmetic repair of defects of the alveolar ridge for implant for the correction of the alveolar ridge in a limited area for removable prosthetics.

There are ways to restore the anatomic shape of the alveolar ridge of the jaw by filling bone crest synthetic bone graft (see for example, Arthur Ashman implantation of the implant into the jaw bone after filling bone crest synthetic bone graft BIOPLANT-HTR, W. Clinical dentistry, No. 4, 2001, p.56-59). In this analogue after pivoting, the medicine periosteal flap detachment tissues bore holes in the bone every 3-4 mm. To stimulate bleeding syringe with a filter cap on the end carry the blood sample through the filter nozzle. Placed on the bleeding jaw ridge synthetic bone alloplast mixed with blood from a syringe. Close the wound and stitched on the flap.

The main disadvantage of this method is the location on the crest of the alveolar ridge of the jaw synthetic bone alloplast. In Zmeiny cases of rejection alloplast and as a consequence not resume the alveolar ridge of the jaw due to the lack of stimulation of development of their bones.

Another analogue of the proposed method is the method of restoring the anatomic shape of the alveolar ridge of the jaw bone by bone grafting (see, for example, Whithouse, Naumov PV and other Surgical stomatology, M.: Medicine, 1981, str-531)consists in preparing a bed for a bone graft, taking a bone graft, placing bone graft in the prepared bed and suturing the soft tissue. The disadvantages of this analogue is a fairly complex operation, due to the need to take the graft from the rib or ridge Powszechny bone of the patient. Additional trauma. The risk of complications. Insufficient fixation of the graft to alveolar ridge of the jaw.

The closest analogue of the proposed method is a method plastics alveolar ridge of the jaw (see, for example, patent RF № 2181568, IPC And 61 In 17/34 published 27.04.2002), namely, that after antiseptic treatment of the bottom and walls of the alveolus of the tooth sprinkled crushed powder of allogenic demineralized freeze-dried sponge or breakast, the remaining space stamp blocks of the same graft, and mucoperiosteal flap, cut and mobilized with the vestibular surface of the alveolar ridge before the closure is placed overlapping n is devitalizirovannah oral gingival margin. The disadvantage of this method include the need to use powder and block graft.

The objective of the invention is to improve the reliability of the restoration of the anatomic shape of the alveolar ridge of the jaw.

The technical result is achieved by the fact that in the present invention are cutting the bone of the alveolar process through forests or separation discs, stupidly nadramia the bone plate of the alveolar process, stack graft to alveolar ridge, surrounded by bony plates of autocost sandwich, strengthen Muco-periosteal flap, sutured the wound and knotted stitches.

The proposed method is as follows.

Cut out Muco-periosteal flap exceeding the size of the defect, throw back the flap with the exposed bone, mobilize taking into account the future increase of the bone. Through forests or separation discs with water cooling at the speed of 130-150 rpm are cutting the bone of the alveolar process. Stupidly nadramia the bone plate of the alveolar process, vestibular and/or oral, depending on the readings.. Cut out the size of the defect dried block graft and soaked in isotonic sodium chloride. Stack transplant alveola the tion process and surround with vestibular and oral sides of the bone plates of autocost sandwich, previously cut. Strengthen the Muco-periosteal flap or a weakness of the Muco-periosteal flap, pre strengthen one of the varieties of biomembranes. Sutured the wound and knotted stitches. If necessary, cover removable protective plate, pre-made on the plaster model from acrylic plastic.

As a transplant can be used, for example, freeze-dried bone graft or a synthetic material.

This sequence of operations and new operations in the way for more secure fixation of the graft on the surface of the alveolar ridge of the jaw, a more rapid restoration of the anatomical shape of the bone and stimulation of development of bone.

A method of surgical repair of anatomic shape of the alveolar ridge of the jaw, including cutting out Muco-periosteal flap exceeding the size of the defect, pivoting the flap with the exposed bone mobilization, characterized in that conduct cutting the bone of the alveolar process through forests or separation discs, stupidly nadramia the bone plate of the alveolar process, stack graft to alveolar ridge, surrounded by bony plates of autocost sandwich, strengthen mucous is-periosteal flap, sutured the wound and knotted stitches.

SUBSTANCE: one should perform an incision along mucous-gingival border of patient's jaw up to periosteum, separate mucosa at the section of transitional fold, replace separated mucosa into area of deeper vestibular arch to be sutured to periosteum, cover wound surface with a not free fragment out of the section of alar-mandibular fold. One should perform the first incision to form a fragment at the part of mucous-gingival maxillary border behind the tuber, continue this incision downwards along anterior edge of medial alar muscle towards mandibular transitional fold behind the 8th tooth. Then it is necessary to perform the 2nd incision at the part of maxillary transitional fold behind the 8th tooth by leaving 1 cm against the 1st one. One should continue the incision along the cheek at projection of anterior edge of mandibular branch, connect the second incision with the onset of the first one, separate mucous-submucous fragment beginning from inferior end, moreover, the width of developed fragment in central department should correspond to 1 cm. One should rotate the fragment upon nutritive pedicle at the angle of 90 deg., apply the fragment onto wound surface of vestibular side of maxillary alveolar process, fix the fragment with sutures to mucous edges. In another variant, the first incision for developing a fragment should be performed at the part of transitional maxillary fold behind the 8th tooth. One should continue this incision downwards along anterior edge of medial alar muscle to mandibular mucous-gingival border the 8th tooth. Then one should perform the second incision at the part of maxillary transitional fold behind the 8th tooth from the onset of the first incision by continuing this incision along the cheek at projection of anterior edge of mandibular branch towards transitional fold. Then one should separate mucous-submucous fragment by starting from superior edge, moreover, the width of formed fragment in central department should correspond to 1 cm. Then one should rotate the fragment upon nutritive pedicle at the angle of 90 deg. and apply it onto wound surface of vestibular side of mandibular alveolar part. The innovation suggested enables to improve functional and esthetic results of vestibular plasty of mouth cavity.

EFFECT: higher efficiency of vestibular plasty.
