Overdenture vs Implant-Supported Denture

As a prosthodontist, I often guide patients in choosing between implant-supported dentures and overdentures. Both surpass conventional dentures in benefits, yet have distinct features that merit consideration.

Overdenture vs Implant-Supported Denture

Key Takeaways: Overdentures vs Implant-Supported Dentures

Number of Dental Implants

  • Overdentures: Use 2-4 implants.
  • Implant-Supported Dentures: Typically anchored with 4-6 implants.

Stability and Movement

  • Overdentures: Offer significant stability but allow some movement.
  • Implant-Supported Dentures: Provide enhanced stability, minimal movement during eating/speaking.


  • Overdentures: Removable for cleaning, combining traditional convenience with implant stability.
  • Implant-Supported Dentures: More permanent, not designed for regular removal.

Cost Comparison

  • Overdentures: More cost-effective; single implant around $4,500, 4-implant option averages $9,000-$13,500.
  • Implant-Supported Dentures: Higher cost; $25,000-$35,000 for complete upper and lower restoration.

Functionality and Efficiency

  • Overdentures: Improve chewing efficiency compared to regular dentures.
  • Implant-Supported Dentures: Optimal gum and jawbone stimulation, promoting better oral health.

These key differences demonstrate that while both options surpass conventional dentures in stability, implant-supported dentures lean towards greater permanence and stability, and overdentures offer a balance of stability, removability, and affordability.

Implant-Supported Dentures: Stability and Comfort

Implant-supported dentures anchor securely onto 4-6 dental implants. They offer:

  • Enhanced Stability: With precision ball attachments, these dentures snap into place, limiting movement and providing comfort during eating and speaking.
  • Jawbone and Gum Health: The integration with implants stimulates the jawbone, reducing the need for frequent adjustments and replacements.
  • Aesthetic and Fit: Utilizing digital 3D technology, these dentures offer a natural look and a comfortable, personalized fit.

Overdentures: Balance of Stability and Convenience

Overdentures use 2-4 implants for attachment, providing a balance between the stability of implants and the convenience of removable dentures. They are:

  • Cost-Effective: Overdentures are a budget-friendly alternative that still offers improved stability over traditional dentures.
  • Flexible: Depending on the case, they can support the denture from below or anchor to the sides, with some using a single midline implant.

Maintenance and Care: Ensuring Durability

Both types require:

  • Regular Cleaning: Daily removal and brushing with ultrasonic cleaners and non-abrasive pastes.
  • Professional Check-ups: Bi-annual cleanings and assessments, are especially important for overdentures which may need more frequent relining.

Cost Considerations

The choice often hinges on budget:

  • Overdentures: $4,500-$6,000 for a single implant; $9,000-$13,500 for 4 implants.
  • Implant-Supported Dentures: $25,000-$35,000 for complete upper and lower dentures.

Despite higher upfront costs, the long-term savings and health benefits make them a worthwhile investment.

Personalized Treatment Assessment

When comparing, consider:

  • Jawbone Density and Gum Health
  • Budget and Long-Term Costs
  • Lifestyle and Activity Levels
  • Aesthetic Preferences

Schedule a Denture Consultation

If you’re considering an upgrade from conventional dentures, explore these options further by scheduling a consultation. These modern solutions can significantly improve your smiling, eating, and speaking experiences.

  • Functional Benefits: Minimal movement, ideal for eating/talking.

“With implant-supported dentures, speak 20% faster without appliance movement.” – Dr. Chris Stevens, Prosthodontist


  • Partially Supported: By 2-4 implants.
  • Chewing Efficiency: 92% better than regular dentures.

“Overdenture patients increased biting force by 30-40%.” – Dr. Mary Ford, Prosthodontist

Appearance and Fit

  • Natural Look: Both use materials like porcelain for a natural appearance.
  • Digital Scanning: Assures a precise and comfortable fit.

Adjustability and Longevity

  • Reliability: Both options offer better long-term stability than traditional dentures.
  • Lifespan: Over 15 years with proper care.


Overdentures and implant-supported dentures each offer unique advantages. Your choice should be informed by a thorough evaluation of your personal needs and lifestyle. A prosthodontist can help tailor the best solution for you, paving the way for a more comfortable and confident life.
