Types of Dental Implants

What are the different types of dental implants?

There are only two types of dental implants:

Titanium dental implants
– Most commonly used
– First introduced in 1950

Zirconia dental implants
– Metal free dental implants
– More recently introduced

Dental implants can be categorized in so many different ways. This photo slider shows the different types of implants based on different factors. Below are more details on this topic.


Types of Dental Implants

Researching types of dental implants can easily lead to information overload. This is because dental implants can be categorized based on material, shape, size, attachment mechanism, connection design, surface type, number of components, and much more. Too much information can lead to more confusion than clarity. This is certainly true here.

One way to help sort through this amount of information is to limit the focus on the types of implants that are commonly used and available on the market today. These implants fall into two category types:

Zirconia dental implants

Zirconia dental implants also known as metal free dental implants or ceramic dental implants were introduced in the United States in the last few years.

Zirconia dental implants are made from Zirconium Dioxide. Zirconia is naturally occurring material. It is chemically unreactive and it is one of the most studied ceramic materials. In some patients titanium dental implants can cause a hypersensitivity allergic reaction. Zirconia implants can a good alternative for those patients because zirconia offers better biocompatibility. Various studies have shown that zirconia implants tend to elicit much less hypersensitivity reaction in patients.

Optima Dental was one of the first dental practices to introduce zirconia dental implants in the United States and the first to do so in Oregon. At Optima Dental we utilize Z-Systems zirconia implants.

Titanium dental implants

Titanium dental implants comprise the vast majority of dental implants placed today. Titanium implants can either made from medical grade IV “Pure Titanium” or medical grade V “ Titanium Alloy”. Titanium implants utilized today are root form “screw like” with internal or external connection. These implants come in various diameter sizes from narrow diameter mini dental implants to wide platform large diameter implants.

Types of titanium utilized in dental Implants:

1. Grade 4 titanium implants

Grade 4 titanium is among the commercially pure category of titanium. It is approximately 99% pure titanium with 1% containing other elements that include Oxygen, Carbon, Hydrogen, Iron and Nitrogen.

2. Grade 5 titanium implants

The vast majority of dental implants utilized today are made from Grade 5 Titanium, also known Titanium Alloy. Titanium grade 5 is a medical grade titnaium that is about 90% pure. The other 10% is composed of 6% aluminium, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen.

At Optima Dental we believe that Titanium grade 4 implants offer the best combination of durability and biocompatibility. High quality dental implants manufacturers tend to utilize grade 4 titanium and perform more in depth research. Some of these manufacturers include Nobel Biocare, Straumann, and Astra. These manufactures have gained the American Dental Association seal of acceptance, which sets stricter guidelines than the FDA on implants manufacturers.

At Optima Dental we utilize Nobel Biocare dental implants for our titanium implants.
