\n\t Dental implants are made of medical grade titanium. This metal is inert to the natural tissues of the body, does not cause oxidation and other negative reactions. But in the manufacture of titanium alloys, a small percentage of impurities is allowed, and each element has its own electrochemical potential and bioactivity. When installing implants of different brands, metals-impurities in the acidic environment of the mouth may not combine, causing allergies, galvanic syndrome (“battery effect” in the mouth), rejection of the design.<\/p>\n

\nMaterials for implants <\/h2>\n

\n\t To create implants, metals not subject to corrosion, electrochemical reactions, neutral to the surrounding tissues are used. This is titanium and its alloys – a strong, lightweight material, resistant to corrosion, bioinert, contributing to the rapid formation of bone around the implant.<\/p>\n

\n\t Manufacturers use different grades of titanium for implant constructions. In Russia they use technically pure titanium of VT 1-0 and VT 1-00 grades (GOST 19807-91). Foreign manufacturers use medical titanium of four grades (Grade 1-4 ASTM, ISO) and titanium alloy Ti-6Al-4V (ASTM, ISO) – analog of Russian VT-6. The materials differ in mechanical qualities and chemical structure.<\/p>\n

\nWhat is “medical” titanium <\/h3>\n

\n\t Purified “medical” titanium is a non-magnetic, light, ductile metal, easily amenable to all types of mechanical processing (grinding, milling, etc.). Titanium structures are bioinert, quickly fuse with muscle and bone tissue. Titanium is chemically indifferent to all other metals. Since pure titanium is a soft material, manufacturers use impurities to give it strength.<\/p>\n

\nWhat impurities are added to titanium and for what purpose <\/h3>\n

\n\t The main component of titanium alloys is titanium itself, to which alloying elements are added that give the alloys different properties. They use:<\/p>\n

\n
• zirconium;<\/li>\n
• aluminum;<\/li>\n
• vanadium;<\/li>\n
• molybdenum;<\/li>\n
• iron;<\/li>\n
• cobalt;<\/li>\n
• nickel;<\/li>\n
• chromium;<\/li>\n
• copper;<\/li>\n
• silicon, etc.<\/li>\n<\/ul>\n

  \n\t Alloying additives make the strength of titanium alloy higher and have other features. For example: zirconium is bioinert and is considered a neutral hardener for titanium. Structures made of this alloy are characterized by high biocompatibility, increased mechanical properties. Chromium, nickel or vanadium are added to increase strength, reduce hydrogen embrittlement of the alloy. The addition of these alloyed components makes the alloy cheaper. But given the likelihood of developing a severe allergy to the same nickel, it is not even worth talking about saving money.<\/p>\n

  \nThe danger of inexpensive impurities <\/h3>\n

  \n\t Some manufacturers use titanium alloys containing vanadium, chromium, nickel for dental implants. Mechanical qualities are obtained excellent, but they are toxic to the surrounding tissues, causing allergic reactions. Artificial roots with these metals in the composition, characterized by a lower degree of engraftment. Inclusion of alloying impurities, contributes to the formation of connective tissue layer around the implant and contamination of tissues, which leads to peri-implantitis, rejection of the design.<\/p>\n

  \nWhat materials are used in the ROOTT Clinic <\/h2>\n

  \n\t For the manufacture of implant structures, suprastructures, prosthetic arches and ROOTT prosthetics, titanium grade 5 (Ti Grade 5) is used.<\/p>\n

  \n\t The advantages of the material are:<\/p>\n

  \n
  • Biocompatibility;<\/li>\n
  • absence of toxic impurities (vanadium, nickel, etc.);<\/li>\n
  • increased resistance to corrosion;<\/li>\n
  • quick integration with fabric;<\/li>\n
  • absence of allergies.<\/li>\n<\/ul>\n

    \n\t Grade 5 titanium is referred to as “commercially pure”. It does not cause an aggressive reaction from the immune system, quickly integrates with the jawbone. The quality of the material is confirmed by a certificate of conformity.<\/p>\n

    \n\t In the clinic, titanium is used not only for implants, it is also used for the metal base of orthopedic constructions. It is inadmissible to use nickel-chromium alloy for prosthetic arches. Nickel is a powerful allergen and has a toxic effect on the human body. It is allowed to use a metal alloy of cobalt-chromium, but only in the absence of allergies. In our clinic, to avoid complications in the form of allergic reactions, all products are made only of medical titanium.<\/p>\n
