Implant Overdentures in South Barrington, IL

What an Implant Overdenture Is

An overdenture looks like a conventional denture but has internal attachments that snap onto 2-4 dental implants. The denture is removable by the patient but stays firmly in place during eating and speaking. When removed for cleaning at night, the attachments are clearly visible.

Two main types exist:

Two-implant overdenture: Two implants in the lower jaw, with the denture snapping onto ball attachments or a bar. Most common and affordable option.

Four-implant overdenture: Four implants (often in the upper jaw where bone is softer), with the denture snapping onto a bar or individual attachments. More stability than a two-implant design.

Benefits Over Conventional Dentures

• Dramatically better stability. No slipping or floating during eating and speaking
• Better chewing function. Enjoy foods that were difficult or impossible with a regular denture
• No adhesive needed. Eliminates the mess and inconvenience
• Preserves bone. Implants stimulate the jaw bone, reducing the bone loss that occurs with conventional dentures
• Better speech. Stable denture eliminates the clicking, slipping, and lisping common with loose dentures
• Improved confidence. No fear of the denture shifting during conversation
• Better appearance. Implant-supported dentures can be designed with less bulky palates and thinner flanges
• Longer-lasting. With proper care, overdentures last longer than conventional dentures

The Overdenture Process Step by Step

Step 1: Consultation and Planning. Dr. Allison Bartley evaluates your remaining teeth, jaw bone, and existing dentures (if any). 3D Cone Beam imaging maps the bone available for implants.

Step 2: Extractions (if needed). Any remaining teeth that cannot be saved are extracted. An immediate conventional denture may be delivered to wear during healing.

Step 3: Implant Placement. 2-4 implants are placed in the jaw under local anesthesia (or IV sedation). Most placements take 60-90 minutes.

Step 4: Healing. 3-6 months for implants to integrate with bone.

Step 5: Attachments. Small attachments are placed on the implants.

Step 6: Denture Fabrication or Conversion. A new denture is made with precision-fit attachments inside, or an existing denture can sometimes be retrofitted.

Step 7: Delivery. The denture is fitted and delivered. You practice snapping it on and off.

Step 8: Follow-Up. Adjustments in the first few weeks ensure comfort and function.

Timeline

• Consultation and planning: 1-2 visits
• Implant placement: Single surgical visit
• Healing: 3-6 months
• Denture fabrication: 3-5 weeks
• Total timeline: 5-9 months from start to completion
• Overdenture lifespan: 10-20+ years for the implants and attachments; denture itself may need relining every 2-3 years

Cost Factors

Overdenture cost depends on:

• Number of implants (2 vs. 4)
• Whether you need extractions first
• Whether bone grafting is needed
• Type of attachments (ball, locator, bar)
• Whether you have an existing denture that can be modified

Total investment is higher than conventional dentures but far below fixed full-arch implant bridges. Many PPO dental insurance plans cover a portion; we verify benefits during consultation. CareCredit and GreenSky financing extend treatment across payment terms. See our finance and insurance page.

Risks and Limitations

Surgical risks. As with any implant surgery: infection, bleeding, rare nerve complications.

Need for bone grafting. Patients with significant bone loss may need grafting first, adding time and cost.

Attachment wear. The internal attachments that hold the denture to the implants wear over time and are replaced periodically (every 1-3 years is typical).

Adjustment period. Like any denture, some adjustment time is needed.

Still removable. Overdentures are removed nightly for cleaning. Fixed full-arch implant bridges are not, but cost significantly more.

Implant failure. Approximately 2-5% of implants fail to integrate. Failed implants can usually be replaced after healing.

Who Is a Good Candidate

• Patients currently unhappy with conventional dentures
• Patients missing all teeth in an arch (or soon will be)
• Patients with adequate jaw bone (or candidates for grafting)
• Patients in reasonable general health
• Non-smokers or those willing to quit during healing
• Patients committed to good oral hygiene

Who Is NOT a Good Candidate

• Patients with severe uncontrolled medical conditions
• Heavy smokers unwilling to stop during healing
• Patients with very limited bone and unable or unwilling to receive grafting
• Patients on certain bone-density medications
• Patients unable to remove and clean the denture daily

Comparison: Implant Overdenture vs. Conventional Denture vs. Fixed Full-Arch Bridge

Conventional Denture: Removable, lowest cost, accelerating bone loss, limited chewing, requires adhesive.

Implant Overdenture: Removable but stable, moderate cost increase, reduced bone loss, near-natural chewing, no adhesive.

Fixed Full-Arch Implant Bridge: Permanently attached (not removed by patient), highest cost, minimal bone loss, best chewing function, closest to natural teeth.

For most patients making the switch from conventional dentures, overdentures offer the best combination of improved function and reasonable cost.

Alternatives

• Conventional dentures if implants are not feasible
• Fixed full-arch implant bridges for patients wanting non-removable solutions
• Individual dental implants for patients with some remaining teeth
• Dental bridges for smaller missing-tooth situations

Caring for Your Overdenture

• Remove and clean the denture daily with a soft brush and denture cleanser
• Clean around the implant attachments carefully
• Soak the denture overnight in denture solution
• Attend regular cleanings and exams for implant and denture evaluation
• Replace attachments as recommended (typically every 1-3 years)
