Abstract

The Rect-spring, a new device that simply and effectively resolves ectopically erupting molars, may be applied in cases where the ectopically erupted molar is entrapped by more than two mm. Its design, scientifically logical for changing the direction of force, delivers a continuous distalizing and uprighting force. The Rect-spring can be easily manufactured at chairside and delivered on the same day without the need to take impressions or perform laboratory procedures. With proper activation, it can resolve a severely ectopically erupting molar within three months. It is relatively inexpensive and easy to deliver, causes little irritation, and is less time consuming for patients. It is worth utilizing before introducing Halterman or Humphrey appliances due to its simplicity and economical benefit. The purpose of this clinical report was to describe the design and the clinical application procedure for the Rect-spring and three successfully treated cases.
