Implant-supported dentures attach to dental implants placed in the jaw, which can give more stability than a conventional removable denture. This educational case note describes a full-arch restoration completed at Greenvale Dental House, where six implants were used to support upper and lower dentures. It is general information only; results vary between patients and suitability can only be confirmed at a clinical consultation.
Presenting Clinical Problem
A patient presented to Greenvale Dental House seeking a fixed, long-term way to replace failing and missing teeth.
- Multiple unrestorable teeth across the upper and lower arches
- Missing teeth the patient wanted to replace with a long-term, fixed option
- Difficulty eating and speaking
- A preference for a fixed restoration rather than a removable denture
The primary objective was a full-arch, implant-supported restoration.
Treatment Approach
Planning began with a comprehensive examination and radiographs to assess the remaining teeth and the bone available for implants.
Assessment and planning
- Evaluation of the remaining tooth structure and prognosis
- Assessment of bone quality and quantity for implant placement
- Discussion of implant-supported versus conventional denture options
- Planning a full-arch restoration using six implants
Extraction and implant placement
- Removal of the unrestorable teeth under appropriate anaesthesia
- Surgical placement of six dental implants across the upper and lower arches, a multiple-implant approach
- A healing period to allow the implants to integrate with the bone
- A temporary denture provided during healing
- Assessment of implant stability before the final restoration
Final prosthetic fabrication and delivery
- Impressions for the implant-supported dentures
- Framework design and tooth arrangement
- A try-in appointment to check fit and appearance
- Delivery and attachment of the final implant-supported dentures
- Aftercare instructions and a maintenance plan
Clinical Outcome
Six dental implants were placed across the upper and lower arches, and implant-supported dentures were delivered after the healing period. At review, implant stability and denture function were assessed as adequate, and the patient was maintaining appropriate oral hygiene.
Individual results vary. Implant success depends on bone quality, oral hygiene, general health and healing capacity, and not everyone is a suitable candidate for implants. Implant-supported dentures need regular maintenance and may require adjustment or component replacement over time. Outcomes cannot be guaranteed, and suitability can only be determined at a clinical consultation.
Frequently Asked Questions
What is the difference between implant-supported dentures and conventional dentures?
Implant-supported dentures attach to dental implants placed in the jaw, which reduces movement during eating and speaking, though some movement may still occur depending on the design. Conventional dentures rest on the gums without implant attachment and generally move more. Implant-supported options require adequate bone and surgery, while conventional dentures can be provided without surgery.
How many implants are needed for a full-arch restoration?
Full-arch implant-supported restorations typically use four to six implants per arch, depending on bone quality, jaw anatomy and prosthetic design. Fixed full-arch options such as All-on-4 and related solutions use a similar principle. Radiographic imaging and a full assessment determine the appropriate number and position for each patient.
How long do dental implants last?
Longevity varies between patients. Many implants function well for 15 to 20 years or longer with proper care, while some fail earlier. Factors include oral hygiene, bone density, general health, bite forces and smoking. Regular professional maintenance and daily home care support long-term results.
