Intentional replantation is useful for failed cases of conventional dental treatment - including root canal treatment - to restore the tooth in question. Based on a recent study, it is relatively very successful; prognosis is good for a long period. On the other hand, a tooth that becomes an indication of intentional replantation is often severely weakened throughout several treatments. Moreover, with multi-rooted teeth, extracting without root fracture is difficult. Safe extraction that is free of coronal or root fracture is important, but little information is known as to a concrete, safe way of extraction. There are a few considerations for safe extraction. First, a tooth with orthodontic extrusion force is easier for extraction due to its increased mobility; it increases the amount of the periodontal ligament, which is essential for re-attachment. As a safe way of extraction, the use of physics forceps® has been introduced recently; it minimizes damage to the gingiva and alveolar bone. This paper reports the good result of using atraumatic safe extraction via both orthodontic extrusion and physics forceps®.
