摘要：
FIELD: medicine.SUBSTANCE: upper and lower jaw models made of durable plaster of IV hardness category are obtained. Masticatory and cervical muscle relaxation is performed. Inter-alveolar height and lower jaw position are determined. The jaw models are fixed in the articulator according to the facial arc data and previously obtained registrate. Wax modeling of chewing surfaces of the erased teeth is performed. A dentition impression is obtained after wax modeling using a transparent silicone mass. Based on the obtained silicone impression, composite restoration of the teeth chewing surface is performed. Composite teeth chewing surface restoration can be accomplished in two ways. For the first version, to create composite restoration of the teeth chewing surfaces, two pairs of jaw models are used. The composite material is introduced by layers into the previously prepared silicone impresstion, applying it to the gypsum model where no dental modeling was conducted with simultaneous composite material polymerization. The prepared occlusal pad is removed from the impression and fixed in the oral cavity with a flowable composite material after hard tooth tissue etching and priming. For the second verstion, one pair of jaw models is used, based on which a silicone impression is obtained, after wax modeling of the erased teeth chewing surface. The resulting silicone impression is cut into three parts: vestibular, oral and central, and the central part is removed. Then, by selecting the occlusal overlays colour, first, the vestibular portion of the silicone impression is applied to the dentition and filled with solid composite material, polymerized by a light-curing lamp. Then the oral part of the impression is applied to the dentition, and the occlusal lining oral surface is prepared as well. Thereafter, the method of direct restoration is used to prepare the central part of the occlusal lining, and the occlusal lining is ground by slightly abrasive discs and polished by m
