Potential toxicity of titanium

Titanij se široko primjenjuje zbog svoje biokompatibilnosti i dobrih biomehaničkih svojstava. Pokazuje dobru sposobnost vezanja za živo tkivo i kosti pa se često upotrebljava za zubne, ortopedske i srčane implantate. Upotrebljava se kao čisti titanij ili kao legura na bazi titanija, gdje dodatak drugog elementa titaniju omogućuje dobivanje boljih svojstava od samoga titanija. Unatoč inertnosti, titanij je i dalje podložan koroziji i otpuštanju štetnih metalnih iona u organizam. Većina studija pokazuje da je titanij izrazito biokompatibilni materijal, međutim određene studije ukazuju da materijali od titanija mogu postati nekompatibilni i prouzročiti štetne učinke. S obzirom na široku upotrebu titanija, javljaju se pitanja o mogućoj štetnosti titanija. Stoga je važno i dalje provoditi toksikološka ispitivanja, pomno procijeniti i ispitati potencijalnu štetnost titanija te provjeriti potencijalne zdravstvenerizike za ljude i za ekosustav.Titanium is widely used due to its biocompatibility and good biomechanical properties. Often it is the material of choice for making dental, orthopaedic and heart implants because it has good binding ability to living tissue and bones. It is used as pure titanium or as a titanium alloys, where the addition of another element or more of them allows to obtain better properties than titanium itself. Despite its inertness, titanium is still susceptible to corrosion and the release of harmful metal ions into the body. Most studies show that titanium is a highly biocompatible material, however there are certain studies that show that titanium materials can become incompatible and cause harmful effects. Given the widespread use of titanium, questions arise about its possible harmfulness. It is therefore important to continue to conduct toxicological tests, to carefully evaluate and examine the potential harmfulness of titanium, and to check for potential health risks to humans and the ecosystem
