METHOD OF SPARING PROSTHETICS WITH ADHESIVE HALF-CROWNS Russian patent published in 2014 - IPC A61C13/00 A61C19/45 

FIELD: medicine.

SUBSTANCE: invention relates to dentistry and is intended for application in orthopedic and therapeutic dentistry. Gypsum models of patient's jaws are made. Biomechanics of lower patient's jaw movements is studied. Angles of sagittal and transversal joint paths of patient are determined. Obtained values are marked on scale of joint units of articulator, which imitates individual movements of patient's lower jaw. Gypsum models are placed in claimed apparatus and ceramic thin half-crowns are modelled on them under constant control of interaction of dentitions and articulation contacts, proper to patient. Preparation of teeth before application of prosthesis according to method includes grounding off sharp enamel crests and processing teeth surface by airbrasive machine with powder with size 50 mcm under pressure 20 atm until dull surface of enamel appears.

EFFECT: method makes it possible to reduce trauma and preserve viability of teeth with prosthetic appliance due to elimination of preparation of hard tissues of said teeth.
