\n\t The absence of teeth affects not only the function of chewing, speech, but also emotional state, socialization and self-esteem. Dentures restore physiological functions, equalize the emotional background, and increase self-confidence.<\/p>\n
\n\t The fabrication of dentures is the result of joint work of a dentist and a technician. Each stage of work affects the final result. The manufacturing process depends on the type of construction and materials used.<\/p>\n
\n\t There are the following types of restorations to restore the tooth row:<\/p>\n
\n <\/p>\n
\n\t For fixed restorations, metals, ceramics and zirconium dioxide are used. Metal-ceramic crowns consist of 2 layers: a metal base that is lined with a ceramic composition. The thick double walls require heavy debonding. Zirconium crowns are very strong, so teeth are minimally prepared for them. Newer ceramic compositions, such as E-max, are strong enough to match any shade of tooth color.<\/p>\n
\n\t The same materials can be used for removable prosthetics.\n<\/p>\n
\n\t For removable dentures, the most important element is the base. The base is made of:<\/p>\n
\n <\/p>\n
\n\t Acrylic is the most rigid material. Its disadvantages are microporosity and rapid wear. Acrylic contains substances that cause allergies. Pros – low cost and ease of processing.<\/p>\n
\n Acry Free – a material in which allergens are absent, it is softer and thinner than acrylic. It is easier to get used to such a product.<\/p>\n
\n\t Nylon restorations are comfortable in the mouth, do not cause allergies, but do not distribute the chewing load well enough due to their softness.\n<\/p>\n
\n\t Metals and plastics are used for the attachment elements of partial removable restorations. The same acrylic and plastics based on acrylic resins are used for the base.\n<\/p>\n
