An upper denture supported by 6 implants—often called an implant-supported overdenture or a fixed full-arch prosthesis (All-on-6)—is designed to restore a full set of upper teeth with much greater stability, function, and bone preservation than a traditional denture.
1. Stability and retention
Six implants act as anchors embedded in the maxillary bone.
• Prevents the denture from slipping or dropping
• Eliminates or reduces need for adhesives
• Improves confidence when speaking and eating
2. Improved chewing efficiency
Compared to conventional dentures:
• Significantly higher bite force
• Ability to chew tougher foods (meat, raw vegetables)
• More even load distribution across the arch
3. Bone preservation
Implants transmit functional load to the bone, which helps:
• Reduce alveolar bone resorption (bone shrinkage)
• Maintain facial structure and avoid “sunken” appearance
4. Comfort and reduced palatal coverage
Depending on the design:
• Many fixed options eliminate full palate coverage
• Less gag reflex and more natural taste perception
5. Longevity and durability
• Implants can last decades with proper maintenance
• The prosthetic teeth (acrylic or zirconia) may need periodic replacement or adjustment.
Fixed full-arch (All-on-6)
• Permanently screwed into implants
• Only removed by dentist
• Feels closest to natural teeth

Why 6 implants specifically?
• Provides better load distribution than 4 implants, especially in the upper jaw (which has softer bone than the lower jaw)
• Reduces risk of implant overload or prosthesis fracture
• Allows for a more rigid, stable prosthetic framework

Clinical considerations (important)
• Requires adequate bone volume or bone grafting/sinus lift in some cases
• Good oral hygiene is critical to avoid peri-implant disease
• Regular professional maintenance is essential
