Early diagnosis and treatment of ectopic eruption of first permanent molars
LIU He
Abstract：First permanent molar may be positioned too mesially during eruption and result in the resorption of the dis-tal root of the second primary molar. Ectopic eruption of first permanent molar ususlly causes the loss of the space and de-crease of the arch length,and in severe cases leads to prema-ture loss of the second primary molar. Two types of ectopic eruption of first permanent molars were identified--reversible and irreversible. Intervention should be done toward irrevers-ible ectopic eruption. Therapy could be active or passive. Ac-tive therapy methods include separators and distalizing appli-ances. Passive therapy methods include dissecting the crown or extraction of second primary molar. Clinical manifestation of ectopic eruption of first permanent molar and routine thera-py methods were discussed in this article.
