If the lost posterior teeth are not replaced, the teeth on the opposite side of the arch and the neighbouring teeth start to move into the empty space.
Chewing is transferred to the anterior teeth, which cannot withstand the chewing forces, so they move or wear out.
An important consequence is the loss of the bone that supports the teeth.
Once a tooth is lost, bone resorption begins. The longer we wait to replace the lost tooth, the more bone is lost, making it difficult or impossible to place implants later.
Alternatives:
If there are other teeth in good condition around the lost tooth, they can be prepared and used as abutments for a fixed bridge.
If there are no end teeth to support the bridge, or if they are unsuitable, the only alternative to replacing the lost teeth is a partial denture. This is a mobile prosthesis that fills in the missing teeth and must be removed and cleaned after each meal.
The dental implant solution has an advantage over the alternatives because it:
- provides excellent chewing ability
- provides a fixed prosthesis
- does not affect taste
- does not damage natural teeth and maintains their good prognosis
- implants keep the jawbone stable.
