Dental implants are one of the most advanced and reliable solutions for replacing missing teeth. When patients learn about implant treatment , they often imagine the visible crown the tooth that looks natural and aesthetic. However, the real hero behind the success of implant treatment is hidden beneath the gum line: the dental implant screw.
Many patients ask:
What is the screw inside a dental implant?
What does the implant screw do?
Is the implant screw permanent?
In this comprehensive guide prepared by Mosdent Dental Hospital , we will explain everything you need to know about the dental implant screw, how it works, and why it is essential for long-term implant success.
/ What Is a Dental Implant Screw?
A dental implant screw is a small but extremely important component that connects the implant fixture (the artificial tooth root) to the abutment and crown .
In simple terms:
- Implant fixture → placed inside jawbone
- Abutment → connector piece
- Crown → visible tooth
- Implant screw → holds everything together
Without the implant screw, the dental implant system would not function as a stable and durable tooth replacement.
/ Understanding Dental Implant Components
To fully understand the implant screw, we must first understand the dental implant structure.
A dental implant consists of three main parts:
1. Implant Fixture (Titanium Root)
The part surgically placed inside the jawbone.
2. Abutment
The connector that links the implant to the crown.
3. Crown (Artificial Tooth)
The visible part that looks like a natural tooth.
4. Implant Screw (Abutment Screw)
The dental implant screw connects the abutment to the implant fixture securely.
This tiny component is responsible for long-term stability and function.
/ Why Is the Dental Implant Screw So Important?
The dental implant screw plays a critical role in the success of implant treatment.
Key functions:
- Provides mechanical stability
- Prevents crown movement
- Maintains bite strength
- Ensures long-term durability
Without a properly designed implant screw, the implant crown could loosen or fail over time.
/ What Is an Abutment Screw?
The implant screw is also called an abutment screw.
The abutment screw:
- Sits inside the implant fixture
- Connects the abutment to the implant
- Locks the prosthetic tooth in place
This tiny screw must withstand enormous chewing forces every day.
/ What Material Is the Implant Screw Made Of?
Most dental implant screws are made of medical-grade titanium.
/ Why titanium?
✔ Biocompatible
✔ Extremely strong
✔ Corrosion resistant
✔ Bonds with bone safely
Titanium has been used in dental implants for decades due to its exceptional success rate.
/ How Does the Dental Implant Screw Work?
The dental implant screw works using precision engineering and torque mechanics.
During implant restoration:
- The abutment is placed on the implant.
- The implant screw is inserted.
- The screw is tightened using controlled torque.
- The crown is attached.
This creates a secure and stable tooth replacement.
/ Is the Dental Implant Screw Permanent?
Yes in most cases, the implant screw is designed to be permanent and long-lasting.
With proper care:
- Implant screw lifespan = decades
- Often lasts as long as the implant itself
Regular check-ups ensure long-term success.
/ Can an Implant Screw Become Loose?
Although rare, an implant screw can loosen due to:
- Excessive bite force
- Teeth grinding ( bruxism )
- Poor oral hygiene
- Trauma
At Mosdent, digital planning and precision torque techniques minimize this risk.
/ Signs of a Loose Implant Screw
Patients may notice:
- Crown movement
- Clicking sensation
- Bite discomfort
- Gum irritation
If you experience these symptoms, a dentist should check the implant immediately.
/ How Is an Implant Screw Tightened?
Dentists use a torque wrench to tighten implant screws with precise force.
Correct torque ensures:
- Stability
- Longevity
- Reduced loosening risk
/ Dental Implant Screw vs Implant Fixture
Many patients confuse these parts.
| Implant Fixture | Implant Screw |
|---|---|
| Replaces tooth root | Holds abutment in place |
| Inside bone | Inside implant |
| Permanent | Permanent |
Both are essential for implant success.
/ Do All Dental Implants Use Screws?
Yes. Every modern dental implant system includes an implant screw.
Types of implant restorations:
- Single implant crown
- Implant bridge
- Full mouth implants
All rely on the implant screw for stability.
/ How Long Does an Implant Screw Last?
With proper care:
- 10–25+ years lifespan
- Often lifetime durability
Regular maintenance is essential.
/ How to Protect Your Implant Screw
Follow these tips:
✔ Brush twice daily
✔ Use floss or water flosser
✔ Avoid teeth grinding
✔ Visit dentist regularly
