Dental implant

life science Maturity 5-7 Next article →

A dental implant is a special tool used to replace missing teeth. It is often called an endosseous implant or a fixture. This tool works by connecting directly to the bone of your jaw or skull.

Once it is in place, it can support many different things. It might hold a single crown, which looks like one tooth. It can also support a bridge, a denture, or even a facial prosthesis. Some implants even act as an anchor to help move teeth during orthodontic work.

How does the implant stay so steady in the mouth? It works through a biological process called osseointegration. This is a way for the body to bond with certain materials.

During this process, materials like titanium or zirconia form a very close bond with the bone. First, a dentist places the implant fixture into the bone. Then, the person must wait for a healing time to allow osseointegration to happen. After the bone has bonded to the implant, an abutment is added. This abutment is a small piece that holds the final tooth or dental prosthesis.

Scientists and doctors have studied these tools for a long time. Early examples of successful implants included things like Greenfield's basket.

We can also see how early research worked through old X-rays.

In the United States, the use of these tools is growing very fast. Between 1999 and 2000, only 0.7% of patients with missing teeth used them. By 2015 to 2016, that number rose to 5.7%. Experts think it might reach 26% by the year 2026.

Most implants are made from a metal called titanium.

Many are made of commercially pure titanium, which comes in four different grades. The most common type used is called CP4. This specific grade has very small amounts of carbon, nitrogen, oxygen, and iron. Some implants also use Grade 5 titanium, which is a harder alloy. This alloy contains 6 percent aluminium and 4 percent vanadium. This metal is often used for the small screws and abutments. Some implants are also made of a ceramic called zirconia.

Dental implants are very similar to how we use anchors on a boat. Just as an anchor holds a boat in place, an implant holds a tooth steady. If the bone and gums are healthy, the implant can last a long time. With good care, they can have a five-year survival rate between 93 and 98 percent. Some prosthetic teeth can even last for 10 to 15 years.

They help people chew food and smile with confidence. They are a helpful way to keep a mouth working well for many years.
