Titanium Framework + HIC/Zirconia

Titanium, has been used in the medical and research industry for decades. It is a metal that is strong, lightweight, non-toxic and corrosion resistant. Dental implants made of titanium have a long-term success rate of about 95%, which is largely credited to its excellent biocompatibility due to the formation of a stable oxide layer on its surface.

The commercially pure titanium (cpTi) is classified into various grades, based on difference in oxygen content. Grade 4 has the most oxygen (0.4%), while grade 1 has the least (0.18%).The mechanical differences that exist between the different grades of cpTi are primarily because of the contaminants that are added in minute quantities. Aluminium is added for increased strength and decreased density, and vanadium acts as an aluminium scavenger in order to prevent corrosion.

Titanium Alloys

Titanium is a dimorphic metal i.e. below 882.5 °C it exists as its α-phase, and above this temperature it changes to its β-phase. Its alloys exist in alpha, beta and α-β phases, based on the quantity of other metals added and the temperature of the reaction. Aluminium is an alpha-phase condition stabiliser, while also increasing the strength and decreasing the weight of the alloy. Vanadium acts as a beta-phase stabilizer. The temperature at which αto β transformation occurs changes to a range of temperatures as Aluminium or Vanadium is added to Titanium. The alloys most commonly used for dental implants are of the alpha-beta variety. The most common alloy used contains 6% Aluminium and 4% Vanadium:Ti-6Al-4V
