A titanium post, an abutment, and a lifelike crown: see how the three parts of a dental implant work together to replace missing teeth and keep your jawbone healthy.
An implant rebuilds a missing tooth from the root up using three parts working together: a titanium post, an abutment, and a crown. The post acts as a replacement root; it is set into the jaw surgically and, over the following months, the bone locks around it to form a rock-solid base. The abutment is the small connector that joins the post to a custom crown shaped and shaded to match your other teeth. Because the system replaces the root itself, it keeps the jawbone from shrinking, supports your facial contours, and outlasts conventional bridges and dentures.
The Two Main Implant Designs
Endosteal Implants
This is the design used in the vast majority of cases: a titanium screw anchored directly inside the jawbone. As the bone heals, it fuses to the implant surface (osseointegration), creating a secure anchor for the new tooth. Patients with reasonable bone volume are usually good candidates, and the design handles everything from a single crown to full-arch restorations.
Their strengths are true bone-level integration, flexibility across restoration types, and a bite that feels and works like a natural tooth.
Subperiosteal Implants
When the jaw does not have enough height for a screw-type implant, a subperiosteal design offers an alternative. Instead of going into the bone, a custom metal framework sits on top of it, tucked under the gums. As the gum tissue heals over the frame, it holds everything firmly in place, and small posts poke through the gumline to carry the replacement teeth. Because grafting techniques have improved so much, this design is chosen far less often than it once was.
It still has a role for patients with limited bone height who want to avoid more extensive surgery.
How Implant Treatment Unfolds
Everything begins with a full workup: an oral exam plus X-rays, CT scans, or 3D imaging to measure your bone and confirm you are healthy enough for surgery.
From there, your dentist maps out a plan covering which implant type you need, how many, and exactly where each will go. If your jaw needs reinforcement first, grafting or other preparatory work gets scheduled at this stage.
Placement itself happens under local anesthetic, with sedation available for nervous patients or involved cases. The dentist opens the gum, prepares a precise channel in the bone, seats the titanium post, and closes the site with stitches. The next several months are quiet ones: the bone slowly fuses to the post.
Once integration is confirmed, the abutments go on. These small connectors rise just above the gumline and serve as the attachment points for your final teeth.
Impressions come next, so the lab can build crowns, bridges, or dentures that match your natural teeth in shade, size, and shape. At the final visit, the restorations are fastened to the abutments and your new smile is complete.
Keeping Implants Healthy for Life
- Brush around each implant with a soft-bristled brush and fluoride toothpaste
- Use floss or small interdental brushes to clean the spaces beside implants
- See your dentist for exams and cleanings at least twice a year
- If you grind or clench, sleep with a custom nightguard to shield your implants
- Wear a sports mouthguard for contact activities
- Skip tobacco entirely; smoking slows healing and is a leading cause of implant failure
