You can replace just a single tooth, multiple adjacent teeth, or even a full upper or lower jaw of teeth with dental implants.
How are different numbers of missing teeth replaced by dental implants?
If you're missing one or two individual teeth, each can be replaced by an individual implant, abutment, and crown. This is true whether or not the teeth are adjacent.
Three or four adjacent missing teeth can be replaced with two implants, two abutments, and three or four artificial teeth respectively, in the form of a three- or four-unit bridge, attached to the abutment.
Six or seven missing teeth in a row are typically replaced with 3 implants, 8-10 missing teeth with 4-5 implants, and 9-10 missing teeth require 4-6 implants. To replace a whole upper or lower jaw of teeth (that’s 14 teeth altogether), no more than 8 implants are usually necessary.
Remember that the above numbers above are just guidelines; the number of implants you ultimately get also depends on the volume of bone in your jaw.
People with small jaw bones and those who have experienced bone loss as a result of having missing teeth for a longer period of time may require a bone graft procedure in order to effectively place the required number of implants.
