Abstract: A method for preserving the alveolar ridge using partial extraction therapy. The method comprises de-coronating the tooth to leave a tooth root, de-coring a coronal portion of the tooth root to leave a tooth ring, severing an apical root portion of the tooth root from the tooth ring and removing the apical root portion. The tooth ring provides a ring of natural material that reinforces the coronal part of the tooth socket in the gum and reduces or obviates alveolar resorption.
