How Dental Implants Work: A Step-by-Step Medical Explanation
Dental implants are a medical method of replacing missing tooth roots using biocompatible materials that integrate directly with bone. Unlike dentures or bridges, dental implants are anchored within the jaw and function as a structural replacement rather than a cosmetic substitute.
At Fusion Dental Implants, serving patients throughout Sacramento, Roseville, and Northern California, we perform hundreds of implant procedures each year using the latest techniques and technology.
Understanding the Dental Implant System
A dental implant system consists of three core components:
- The implant fixture (artificial root)
- The abutment (connector)
- The prosthetic tooth or teeth
The effectiveness of dental implants depends on biological integration, mechanical stability, and precise surgical planning.
Step 1: Implant Fixture Placement
The implant fixture is a cylindrical or tapered post, typically made of medical-grade titanium or titanium alloy. Titanium is used because it is biocompatible and capable of bonding directly with bone.
During surgery:
- A pilot hole is prepared in the jawbone
- The implant is inserted with controlled torque
- Primary stability is achieved through mechanical engagement with bone
Primary stability is critical. Without it, the implant cannot integrate and will fail early.
Step 2: Osseointegration
Osseointegration is the biological process by which bone cells grow and attach directly to the surface of the implant.
This process:
- Begins within days of placement
- Continues for several months
- Creates a rigid bone-to-implant interface
Osseointegration is not guaranteed. It is influenced by:
- Bone density and volume
- Surgical technique
- Implant surface design
- Patient health factors (smoking, diabetes, medications)
If osseointegration fails, the implant becomes mobile and must be removed.
Step 3: Healing Phase
After placement, the implant is left undisturbed to allow integration.
Healing timelines vary:
- 8–12 weeks in dense bone
- 3–6 months in softer bone
- Longer if bone grafting was required
During this phase, excessive force on the implant can disrupt integration and cause failure.
Step 4: Abutment Connection
Once integration is confirmed, an abutment is attached to the implant. The abutment connects the implant fixture to the final prosthetic tooth.
Abutments can be:
- Prefabricated
- Custom-milled for precise fit
- Angled to correct implant positioning
Improper abutment selection can lead to mechanical overload or long-term bone loss.
Step 5: Prosthetic Restoration
The final restoration may be:
- A single crown
- A bridge
- A full-arch prosthesis
The prosthetic design must distribute bite forces evenly. Poor design leads to implant overload, screw loosening, or fracture.
Why Implants Replace Roots, Not Just Teeth
Natural teeth consist of a visible crown and a root embedded in bone. When a tooth is lost, the bone that once supported the root begins to resorb.
Dental implants replace the root, not just the visible tooth. This:
- Preserves bone volume
- Maintains facial structure
- Restores functional bite force
This is the primary reason implants outperform dentures and bridges long-term.
