title: Simple treatment of ectopic eruption with a triangular wedging spring.
abstract: The purpose of this clinical report was to introduce a simple and effective way of performing ectopic eruption treatment utilizing a triangular wedging spring. This consists of 3 helical loops in a triangular shape with 0.018-inch Australian wire. The middle helical loop is made for wedging spring action, while the other 2 helical loops are action arms inserted between the second primary molar and ectopically erupting permanent first molar. In this report, the ectopic eruption case was successfully treated with a triangular wedging spring in 2 months. This clinical report demonstrates that a triangular wedging spring can be utilized as a simple, less irritable, and more effective way of correcting ectopic eruption of the permanent first molar.
