What are dental implants?

A number of materials can be used to create dental implants, but they are most often made with titanium or zirconia.

This strong, durable metal is the most common material used for dental implants. Titanium implants offer several benefits that may make them the best choice for you:

• They can be made as either one piece (implant and abutment as a single unit) or two pieces (implant with separate abutment piece). The two-piece option is useful when an implant must be placed in the jawbone at an angle.
  
• Titanium implants are very compatible with the human body and resistant to fractures and corrosion.
• They are shown to be safe and long-lasting, with studies showing that titanium implants have a success rate of 97% and a 10-year survival rate of nearly 99%.¹

Titanium implants are not recommended for people with allergies to metal or certain autoimmune conditions, such as type 1 diabetes or rheumatoid arthritis.

This is a safe, stable ceramic and the second most common material used for implants. Zirconia implants are a more recent invention than titanium options and offer two primary benefits:

• Zirconia can be beneficial if you have metal allergies or medical conditions that prevent the use of titanium.
  
• The absence of metal sometimes provides an aesthetic benefit, especially if you have gum recession. With a titanium implant, the dark metal may be visible near the gumline.

However, zirconia does have a few drawbacks compared to titanium:

• It is a more expensive material than titanium.
• Zirconia is primarily used for individual tooth implants, not multiple teeth or full-mouth implants.
• These implants typically only come as one piece, although there are a limited number of two-piece options. As a result, they may not be an option for implants that must be placed at an angle.

Other materials can be used for dental implants if titanium or zirconia aren’t suitable for you. These include polymers (synthetic materials), ceramics, and some metals, such as gold or cobalt-based alloys.

Dental implants are not one-size-fits-all. Implants come in different lengths and widths, and your dentist or oral surgeon will choose the appropriate implant based on your unique needs. They will consider many factors, including the size and shape of your jawbone, the number of teeth missing, the health of surrounding structures (such as your sinuses), and the position of your remaining teeth.

The implant body and dental abutment of standard dental implants usually have a diameter between 3 and 6 millimeters.

Because they are stronger and longer lasting than mini dental implants, these are still the best and most common option if your jaw is healthy enough to hold them.

Potential downsides to standard dental implants include:

• They are more expensive than mini dental implants.
• The procedure involves more invasive surgery and requires additional healing time.
• Standard size implants may require more office visits than mini dental implants, so the duration of the entire treatment is longer.

These are smaller than standard dental implants and typically have a diameter of less than 3 millimeters. They also combine the implant body and dental abutment into a single screw-like piece that can be placed at the same time – removing the need for a separate appointment to secure the abutment.

Mini implants can be placed into the jawbone after a small incision. Their placement is usually very simple, and most people can resume normal activities quickly.

Mini dental implants are most often used if your jawbone is too small or if space is too narrow to hold a standard dental implant. Mini implants can also be effective as long-term support for dentures.

They offer a few benefits over standard dental implants – the cost is usually lower, they are less invasive, and they typically require fewer dental office visits.

However, mini dental implants are not as strong or long-lasting as standard size implants. As a result, they will likely need to be replaced eventually.

Prior to implant surgery, your dentist or oral surgeon will also do a thorough assessment of your jaws and available bone support. Additional procedures, such as bone grafts or sinus procedures, may be required before an implant can be placed.

Dental implant surgery involves multiple steps, starting with removal of the damaged tooth and ending with placement of the artificial tooth. Placement of standard dental implants is an outpatient surgery and most often performed in stages over the course of several months. Most of this time will be spent between procedures, which allows you to heal and gives your jaw time to bond with the implant body.

The two most common types of dental implant procedures are:

• In the bone (endosteal implant): This type of implant procedure is performed most often. It involves surgically placing a screw (typically made of titanium) into your jawbone, so the implant can hold the artificial tooth in place. 
• On the bone (subperiosteal implant): This method is used if your jawbone cannot support an endosteal implant. A subperiosteal implant is a metal frame placed between the jawbone and gums, underneath the periosteum (a thin layer of tissue between the gums and jawbone). Over time, your gums heal, and the frame fuses to your jawbone.

The specifics of how the dental implant surgery is performed may vary depending on your overall health, oral health history, and the type of implant used.

Dental implants are safe and long-lasting when they are appropriately placed and properly cared for. By replacing damaged or missing teeth, they support your ability to chew, speak, and feel comfortable with your appearance.
