Dental Implants: An Overview
Definition and Purpose
Dental implants are surgical components that interface with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or to act as an orthodontic anchor. Their primary purpose is to replace missing teeth, thereby improving the patient’s ability to chew and speak, while also preserving facial structure and preventing bone loss.
Historical Development
The journey of dental implants began in the 1950s with the discovery of osseointegration, where bone cells attach directly to a titanium surface, firmly anchoring the implant. This breakthrough paved the way for the modern dental implant, which has undergone continual improvements in design, materials, and surgical techniques, enhancing their success rates and accessibility.
Types of Dental Implants
There are primarily two types of dental implants:
- Endosteal Implants: These are the most common type, surgically implanted directly into the jawbone. Once the surrounding gum tissue has healed, a second surgery is needed to connect a post to the original implant, followed by attaching an artificial tooth (or teeth) to the post individually, or grouped on a bridge or denture.
- Subperiosteal Implants: These consist of a metal frame that is fitted onto the jawbone just below the gum tissue. As the gums heal, the frame becomes fixed to the jawbone. Posts, which are attached to the frame, protrude through the gums for mounting the artificial teeth.
Types of Dental Implants and Their Features
| Type | Material | Placement | Suitable For |
| Endosteal Implants | Titanium, Zirconia | In the jawbone | Patients with a healthy jawbone |
| Subperiosteal Implants | Titanium | On top of the jawbone | Patients with minimal jawbone height |
- Endosteal Implants: Materials – Titanium, Zirconia; Placement – In the jawbone; Suitable For – Patients with a healthy jawbone.
- Subperiosteal Implants: Materials – Mainly Titanium; Placement – On top of the jawbone under the gums; Suitable For – Patients with minimal jawbone height or who cannot undergo a bone augmentation procedure.
What Does Dental Implants Look Like?
Dental implants typically resemble small, screw-like posts. Made of titanium or zirconia, they are designed to mimic the root of a natural tooth. Once implanted, they are not visible, as they are anchored in the jawbone beneath the gum line. The visible part of a dental implant is the crown, custom-made to match the color and shape of surrounding teeth, ensuring a natural and seamless appearance in the mouth.
