Time-saving fixed lingual retainer using DuraLay resin transfer.

There is general agreement on the necessity of fixed lingual retainers to prevent relapse in many patients after active orthodontic treatment. Several methods for delivering fixed lingual retainers have been introduced. However, bonding a lingual retainer is still challenging because it requires long working time and has a risk of contamination from saliva and moisture, which can cause bonding failure. In addition, it is difficult to adapt the retainer wire to perfectly fit the lingual surfaces of an anterior tooth. We developed a method of fabricating a fixed lingual retainer using DuraLay resin (Reliance Dental Manufacturing, Worth, Ill) and have used this method with satisfactory results for nearly 10 years on thousands of patients. This technique has proven to be a reliable, convenient, and time-saving procedure.
