ALVEOLAR BONE PLASTY METHOD Russian patent published in 2019 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical dentistry and can be used in alveolar bone plasty. Trapezoidal incision is made along the crest of the alveolar process within the jaw defect. Mucoperiosteal flap is separated. External surface of the alveolar process is skeletonized. Surface decortication is performed in the jaw defect area. Limiter is fixed on the vestibular side outside the zone of suspected augmentation. Augmentation areas are filled with osteoplastic material and the augmentation zones of the limiting membrane are closed with subsequent wound closure. At the same time lateral sides of trapezoidal section are made stepped with step height and pitch varying from 0.2 mm to 0.4 mm. Second mucoperiosteal flap is peeled from the palatine or lingual side in the same region. Performing surface decortication of the bone until blood dew appears. Limiter used is resorbable collagen membrane. It is first fixed from the palatine or lingual side with overlapping of the jaw defect, and then fixed on the vestibular side to form a tunnel above the defect area. Osteoplastic material for filling the augmentation zone is represented by a mixture consisting of auto-shavings, bone of animal origin and non-stabilized hyaluronic acid at ratio of 2:1:0.5.

EFFECT: method provides reducing the length of rehabilitation of patients, enables recovering the volume of the alveolar jaw and helps to reduce the length of treatment of the patient by using a trapezoidal technique, peeling two mucoperiosteal flaps, using a resorbable collagen membrane and a mixture of auto-shavings, bone of animal origin and non-stabilized hyaluronic acid.
