Hemisection
This procedure involves
removal of one-half of a tooth. The remaining half will be restored as a one-rooted
tooth, and is usually attached or anchored to an adjacent tooth, for additional
support and stability.
Root
Amputation
Root amputation refers
to the removal of one root in a multi-rooted tooth.
These procedures may become
options for treatment when there is a persistent endodontic failure in ONLY
one root of a "key tooth" which must be kept, or if there is significant
bone loss around an individual root due to periodontal (gum) disease. With
the advent of modern dental implants, hemisection and root amputation are
often done as a "temporary measure" to allow enough bone healing,
so an implant can be placed at a later date.
