title: Treatment of Ectopic Permanent Maxillary First Molar Using a K-loop.
abstract: Ectopic eruption of permanent maxillary first molar can cause root resorption of adjacent primary second molar, thus leading to early loss of primary maxillary second molar. Therefore, it is necessary to correct ectopic maxillary first molar. This case report demonstrates that K-loop can be used as a simple, comfortable, and easier method to correct ectopic eruption of permanent maxillary first molar in existing severe root resorption on adjacent primary second molar.
