| 成果简介 | NOVELTY - Invention relates to medicine, namely to surgical dentistry. Local anaesthesia is performed with 2% lidocaine hydrochloride solution with single-stage tissue hydropreparation. In anticipation of oral cavity longitudinal incision simultaneously mucous layer, submucosal layer and a periosteal layer of the palate along the border of the attached and unattached gums from the tuber to the maxillary maxillary tooth. Then, the direction of the incision is changed, and an apex of the alveolar process is crossed by a transverse incision. Incision is retracted by 5 mm along a palatine surface from the frontal palatine group of teeth and the incision is extended to an incisive papilla and at distance of 5 millimeters enveloped with an incision with the end of the incision near the midline of the palate. Further, the full-layer mucous-periosteal palatine flap is detached from the surface of the palatine bone to visualize a greater palatal opening. Visualizing the large palatine opening and the palatine neurovascular bundle emanating from it, the soft tissues are prepared and a palatine neurovascular bundle is identified with observing the prevention measures of traumatic injury of the small palatine artery and small palatine nerve. Further, on the inner surface of the cut full-thickness mucous-periosteal flap, an arcuate incision is made, not reaching 11.5 cm to a small palatine artery and a small palatine nerve. Further, splitting of full-thickness mucous-periosteal palatine flap into two flaps - subepithelial flap and epithelial flap. Splitting and formation of two layers is completed at distance of 68 mm from medial edge of full-layer mucous-periosteal palatal flap. Subepithelial flap includes a periosteal layer and a submucosal layer. Epithelial flap faces the oral cavity and includes a mucous layer and a portion of the submucosal layer with preserved peripheral palatal (small palatine artery and small palatine nerve) branches of the neurovascular bundle. Subepithelial flap is moved to close the perforation in the region of the removed tooth and pulled under the vestibular edge of the gum from the buccal side with a U-shaped suture. Further, the sub-epithelial flap of the full-layer split mucous-periosteal palatine flap is laid and sequentially fixed along the periphery by interrupted sutures on the vestibular surface, vertex and palatine surface of alveolar process. Epithelial flap is laid back to close the defect in the sky. It is fixed along the periphery with interrupted sutures. USE - Medicine. ADVANTAGE - Method enables reducing intraoperative injuries with preservation of high degree of effectiveness. 1 cl, 3 dwg, 2 ex |
