Abstract |
Impaction is generally defined as the lack of eruption of a tooth after the normal age for the eruption. An impacted tooth may appear blocked by another tooth, bone, or soft tissue, but cause of tooth impaction is often unknown. The clinician should consider the various treatment options available : (a) No treatment and observation, (b) surgical exposure and orthodontic traction (c) auto transplantation (d) extraction. These cases were about the patients with delayed eruption of maxillary central incisor. We surgically exposed impacted tooth and guided it into normal position by the orthodontic traction. Especially, in case 1, #21 was ectopic impacted state with root dilaceration. It is required to examine further root development and alignment of dentition serially. |
