METHOD OF TAKING IMPRESSIONS WITH APPLICATION OF INDIVIDUAL SPOON IN PROSTHETICS WITH ORTHOPEDIC CONSTRUCTIONS Russian patent published in 2012 - IPC A61C9/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to orthopedic dentistry and is intended for taking impressions with application of individual spoon in prosthetics with orthopedic constructions. Impression from both parts of jaw is taken with simultaneous registration of central occlusion. Model of individual spoon is made, for which purpose on gypsum model marking of boundaries, isolation of stumps of prepared teeth undercuts and dentitions with wax. Kapron mesh is cut out laid on chewing surface and cutting edges of teeth in places of closure with antagonists. In areas of included or end defects, light-polymerised plastic is laid with excess in plastic state. Individual spoon, which copies shape of stumps of prepared teeth and tissues of prosthetic bed, is formed, edges of kapron mesh are fastened into its sides. Articulator is closed to obtain impressions of dentition in area of preparation or absence of teeth. Model with spoon is extracted from articulator and placed into light-polymerisation chamber. After polymerisation spoon is extracted from chamber. Fitting in oral cavity, correction of closure in area of central occlusion are carried out until tight closure with teeth-antagonists is obtained. Impression in position of central occlusion under chewing pressure is taken.

EFFECT: method makes it possible to reproduce relief of prosthetic bed exactly due to constant pressure and distinct positioning of individual spoon without possibility of its displacement.
