FIELD: medicine. SUBSTANCE: crystal-to-amorphous (glass-like) phases ratio in dentine layer is to be within 1:3 - 1:5 by mass and within 1:1 to 1.5:1 by mass in the ground layer. The method involves subjecting metal coatings to multiple heating and cooling (5 thermocycles at least) in 20-930- 20 C temperature range without destroying integrity. Changes in the value of thermal expansion coefficient do not exceed 55•10-7 C. EFFECT: enhanced accuracy of the process; high quality of the product. 5 dwg
