Replacing several teeth is a design problem before it is a surgical one. The question is not how many teeth are missing but how many implants the restoration actually needs, and those are rarely the same number. Replacing several teeth with implants can mean one post for each tooth or fewer posts that support a bridge, and the plan depends on how many teeth are missing and where, the amount of bone, the bite forces on that part of the jaw and how the finished teeth will be cleaned.
Situations that lead to multiple dental implants
- Several teeth missing in the same area
- Teeth lost at different times across one jaw
- An existing bridge or partial denture that has failed
- Wanting to avoid a removable partial denture
- Planning replacements before more teeth are lost
What the plan may involve
- Individual implants with separate crowns
- An implant bridge supported by fewer implants
- Combining implants with existing sound teeth in the plan
- Full-arch treatment where most teeth are failing
- Staging treatment across more than one phase
What long-term studies report for implants
Longitudinal studies generally report implant survival of about 90 to 95 percent over five to ten years. The main late problem is peri-implantitis, inflammation and bone loss around the implant, and its reported rate ranges from about 3.6 to 22 percent of implants depending on the study population and how it was defined. Gum disease, diabetes and smoking raise the risk.
For several implants at once, that is the practical reason maintenance belongs in the plan from the start: each additional implant is one more site that has to be kept clean, and a professional cleaning schedule is the usual way to catch early bone changes.
Common questions
Multiple Dental Implants: questions people ask
Do I need one implant per missing tooth?
Usually not. Implants can support bridges spanning more teeth than there are implants, which reduces surgical sites and cost: see implant bridges.
Can implants be combined with my natural teeth?
Implants and natural teeth are generally not joined together in one restoration, because they move differently in the bone. They can both be part of a plan, restored separately.
Is it cheaper to do them all at once?
Sometimes, because surgical visits are combined. Phasing is also legitimate and may suit budget or healing. Ask for both sequences priced.
What if I lose more teeth later?
Worth raising at the planning stage. A plan that anticipates a questionable tooth failing is easier to extend than one that assumed everything else would last.
How is a plan for several implants designed?
Replacing several teeth is a design problem before it is a surgical one. The question is how many implants the restoration actually needs, and that is rarely the same as the number of missing teeth. Options are separate crowns, an implant bridge on fewer implants, or combining implants with existing sound teeth.
When do multiple implants come up?
When several teeth are missing in the same area. When teeth were lost at different times across one jaw. When an existing bridge or partial denture has failed. When you want to avoid a removable partial denture. When you are planning replacements before more teeth are lost.
