The Medical Application of Titanium
Medical Grade Titanium
Titanium 6AL4V and 6AL4V ELI, alloys made of 6% Aluminum and 4% Vanadium, are the most common types of titanium used in medicine. Because of its harmonizing factor with the human body, these titanium alloys are popularly used in medical procedures, as well as in body piercings. Also known as Gr. 5 and Gr. 23, these are some of the most familiar and readily available types of titanium in the US, with a number of distributors specializing in these specific grades.
Ti-6Al-4V and Ti-6Al-4V ELI offer greater fracture-resistance when used in dental implants. The implant procedure begins with the insertion of a titanium screw into the jaw. The screw resembles and acts like the root of the tooth. After an allotted amount of time has passed for the bone to have grown into the medical grade titanium screw, a fake tooth is connected to the implant.
Benefits of Medical Titanium
Strong
Lightweight
Corrosion Resistant
Cost-efficient
Non-toxic
Biocompatible (non-toxic AND not rejected by the body)
Long-lasting
Osseointegrated (the joining of bone with artificial implant)
Long range availability
Flexibility and elasticity rivals that of human bone
Uses of Medical Titanium
Most all of us know someone who has required surgery to replace a failing hip socket, shoulder joint or severely broken bone. It’s very likely medical grade titanium was the material of choice for the surgeons when reconstructing these parts of the body. As evidenced in the previous section, natural titanium properties make it a perfect alloy to be used within the body.
Medical grade titanium is used in producing:
Pins
Bone plates
Screws
Bars
Rods
Wires
Posts
Expandable rib cages
Spinal fusion cages
Finger and toe replacements
Maxio-facial prosthetics
Some of the most common uses for titanium are in hip and knee replacement surgeries. It is also used to replace shoulder and elbow joints and to protect the vertebrae following complicated and invasive back surgery. Titanium pegs are used to attach false eyes and ears and titanium heart valves are even competing with regular tissue valves.
Surgical Titanium Instruments
There are a number of characteristics that make titanium the perfect choice for surgical instrumentation:
It’s harder than some steel, yet lighter in weight.
It is bacteria resistant.
Again, it can be used in conjunction with instruments emitting radiation.
Titanium is incredibly durable, giving instruments greater longevity.
Because of these great properties, it is used to create a number of titanium surgical devices:
Surgical forceps
Retractors
Surgical tweezers
Suture instruments
Scissors
Needle and micro needle holders
Dental scalers
Dental elevators
Dental drills
Lasik eye surgery equipment
Laser electrodes
Vena cava clips
Dental Titanium
As mentioned earlier, titanium has the ability to fuse together with living bone. This property makes it a huge benefit in the world of dentistry. Titanium dental implants have become the most widely accepted and successfully used type of implant due to its propensity to osseointegrate. When bone forming cells attach themselves to the titanium implant, a structural and functional bridge forms between the body’s bone and the newly implanted, foreign object.
Titanium orthodontic braces are also growing in popularity. They are stronger, more secure and lighter than their steel counterparts. And of course, medical grade titanium’s biocompatibility makes its use in braces even more beneficial than its competing alloys.
