What dental implants are commonly made of?
Dental implants are surgical devices that support a prosthetic or orthodontic appliance by forming a direct interface with the alveolar bone. Ever since dental implants came into discovery, titanium has been the cornerstone material for dental implants. The key discovery of osseointegration by Branemak between titanium and bone has led to its widespread usage as a dental implant material. Over the years, considerable scientific and clinical evidence has established its usage as the main constituent of dental implants. Also, being a pure metal that is sturdy, light in weight, corrosion-resistant and non-toxic has made it a de facto metal of choice for implant manufactures for decades. Besides, the large range of applications and positive user experiences have produced high levels of confidence in the efficiency of many titanium implants. In recent years, despite the availability of many alternative dental implant materials, titanium dental implants are still most used by dental implantologists and clinicians.
What are grade -5 titanium implants and where it is commonly used?
Commercially pure titanium, available for the dental application comes in four grades, i.e, Grade 1 to 4. This grade differs in physical properties of the titanium like ductility, corrosion resistance, and strength. Graded based on its oxygen and iron contents, these elements exert a substantial effect on its mechanical properties. However, this commercially pure titanium is not preferred in areas requiring high-stress resistance. Grade 5 titanium implants (Ti-6Al-4V) are the material of choice in such conditions. Although grade 5 titanium is commonly used in orthopedics appliances, owing to its superiors mechanical properties and high Young’s modulus, its uses as dental implants in high-stress areas are increasing.
Why grade5 titanium is better for dental implants?
Grade 5 titanium dental implants offer similar osseointegration performance as commercially pure titanium along with better strength and fracture resistance. Grade 5 titanium alloys ensure load transmission to bone tissues over a long time, which is necessary when damaged hard tissues are replaced by prostheses. Grade 5 titanium implants have also shown good longitivity. On average with meticulous case planning and proper treatment a titanium dental implant if well osseo-integrated, lasts for around 20 years.
Like other commercially pure titanium, Grade 5 alloy (Ti-6Al-4V) biocompatibility stems from its ability to form an impermeable layer of titanium oxide (TiO2) that serves as a deterrent to chemical attacks, particularly from fluids in the human body, as well as due to its low thermal conductivity. Due to its highest corrosion resistance, commercially pure titanium dental implants are often considered as the most biocompatible dental implants.
How grade 5 titanium implants differ from other grades?
Unlike other commercial titanium grades, the surface of grade 5 titanium (Ti-AL-4V) has a different composition. Along with TiO2, this grade 5 titanium alloy contains both vanadium and aluminum in the surface layers, usually as the appropriate metal oxides which alter cell-metal interactions. Leaching out of vanadium and aluminum rarely leads to allergic reactions as the levels remain well below those needed to produce toxic effects.
