FIELD : medicine.SUBSTANCE : invention refers to medicine, particularly dentistry, and is applicable in diagnosing and treating dysfunctions TMJ, planning of prosthetic repair and demonstration to the patient of the future size and aesthetics of dentures. Patient' s mandibular functioning and articulation (motion) is diagnosed with recording a trajectory of movements in space relative to a hinged axis, angles of displacement of condyles of mandibular joints in motions on Freecoder BlueFox equipment. Obtained mandibular motion diagrams are analysed to exclude pathological trajectories of the joint with compensatory displacement in an articular capsule TMJ. Method comprises determining a physiological position of condyles of joints TMJ. After that position of jaw models is transferred and fixed in this state in articulation system. Technical sheet for adjusting the medical fully adjustable articulator is obtained. Obtained gypsum models of the patient are gypsum-plated into the articulator in a normal physiological position TMJ. Gypsum models on scanner are digitized into STL format, position of models of jaws in CAR-specific interocclusion physiological separation on scanner is digitized into STL format, obtained images in STL model format and position relative to each other jaws are loaded into virtual articulator Amann Girbach. Three-dimensional computer model of the digital occlusal splint is created in the image processing program and creating a three-dimensional image of prosthetic structures of Zirconsahn equipment. ODS is used to make an occlusal digital splint on obtained 3D image in STL format by milling CAD / CAM equipment Zirconsahn from plastic blocks PMMA, the prepared splint is fitted in the oral cavity on the dental arch.EFFECT : method enables higher quality of diagnosing and treating dysfunctions TMJ, eliminate errors when making splint, as well as by using plastic PMMA, to increase strength and durability of the splint, excluding the toxic effect on the patient' s body with monomer residues.1 cl, 17 dwg, 1 ex
