FIELD: medicine.SUBSTANCE: group of inventions refers to medicine, namely to orthopaedic dentistry, and is intended for replacement of wedge-shaped defects of teeth. Dental preparation is performed with expansion of borders around wedge-shaped defect. Cavity of a complex shape with boundaries coinciding with the defect is formed in the preparation process. Further, additional retentional points are created: two of them represent cavities changing to aproximal tooth surfaces, and an additional semi-circular area within the enamel for the veneer part of the insert, on the vestibular surface of the tooth, is coronal of the defect. Gingival fold is created to apical to the defect to restore the gingival joint. Then the impressions are removed with silicone material, models are made and fixed in the occludator or articulator. Model of an insert from modelling wax is made with modelling of a veneer part of the insert, additional retentional elements, and the expressed convex subequatorial zone on a vestibular surface. Seam is made on a gingival surface of the insert. Further, the tab is scanned and its three-dimensional computer model is created. Insert is made by milling from lithium disilicate based lithium-based ceramic glass unit. Ready insert is fitted on the models and in the oral cavity, and, after selective pickling of hard tooth tissues, etching of the inner surface of the insert is fixed on a composite material of double curing.EFFECT: method enables improving insert fixation, improving aesthetic properties of the structure and providing a dentogingival attachment.2 cl, 4 dwg, 3 exГруппа изобретений относится к медицине, а именно к ортопедической стоматологии, и предназначена для замещения клиновидных дефектов зубов. Проводят препарирование зуба с расширением границ вокруг клиновидного дефекта. В процессе препарирования образуется полость сложной формы с границами, совпадающими с дефектом. Далее создают дополнительные ретенционные пункты: два из них представляют
