The answer first

Intentional replantation may be considered when conventional retreatment or apicoectomy is difficult, there is no root fracture, and periodontal tissues remain preservable. It is not suitable for every tooth.

Key points

Minimizing periodontal ligament damage is essential.
Extraoral time should be kept as short as possible.
Root resorption or ankylosis requires follow-up.

What is intentional replantation?

A tooth is removed with minimal trauma, treated outside the mouth, and replanted in its original position.

When is it considered?

It may be reviewed as a final preservation option when root canal access or ordinary apical surgery is not feasible.

What affects prognosis?

Root integrity, periodontal ligament condition, extraction difficulty, extraoral time, bone, and bite all matter.

How should it be compared with an implant?

Preserving a natural tooth has advantages, but prognosis may be uncertain. Both options should be compared honestly.
