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 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.
