Choosing between All-on-4 and All-on-6 implants depends on your needs. Most people qualify for All-on-4. Want more teeth or a stronger bite? All-on-6 might suit you better. Six implants spread chewing pressure more effectively. But your jawbone matters. All-on-4 requires less bone than All-on-6. Also, All-on-6 usually costs more.
Thinking about replacing missing teeth? Wondering about these options? We explain the key differences here. Learn how they compare. Understand what affects the choice. See the cost differences.
What are All-on-4 Dental Implants?
All-on-4 implants replace a full arch of teeth. Dentists place four titanium posts in your jawbone. These posts act like tooth roots. They hold a fixed bridge of artificial teeth. This solution is nearly permanent. It’s for people missing most or all teeth.
First, any damaged teeth and infected tissue must be removed. Then, four implants go into your jaw. Two straight implants sit in the front. Two angled implants sit in the back. Angling avoids important nerves and sinuses. It can also create a wider smile.
Connectors (abutments) attach to the implants. Temporary teeth are fixed onto these connectors. Your jaw needs time to heal. Bone must fuse with the implants. This takes 3 to 6 months. After healing, your dentist fits stronger, permanent teeth.
All-on-4 vs. All-on-6: Key Differences
The main difference is implant number. All-on-4 uses four implants. All-on-6 uses six. Both replace a full arch. But more implants offer advantages.
- Support: Six implants provide greater support.
- Chewing: Pressure spreads more evenly with six implants.
- Teeth Count: All-on-6 typically supports one or two more teeth per arch.
- Bone Needed: All-on-4 requires less jawbone. This makes it suitable for more people.
- Bone Grafting: Rarely needed for either procedure on the lower jaw. Only 5-7% of upper jaw cases need it.
How Do You Choose?
Bone health is critical. But other factors matter too. How many teeth are missing? Is gum disease present? Your dentist must treat gum disease first. They will check your overall health. Conditions like diabetes or osteoporosis are considered.
A special scan (CBCT) checks your jawbone. Sometimes, bone is too thin or soft. Then, your dentist might suggest other implants. Cheekbone or back jawbone implants are options. Severe jaw problems might prevent All-on-4 or All-on-6.
Do They Last Long?
Yes. Both types can last over 20 years with good care. The implant posts fuse with your bone. This is very stable. The artificial teeth might need replacing after 15-20 years. Regular dental check-ups are essential. Your dentist ensures everything stays correct.
Cost in Australia
