Alignment that won't affect your lifestyle!

Invented and developed by Dr. Benjamin A. Cassalia, the Wirelign® (C5 Hidden Orthodontics) procedure is a completely invisible orthodontic procedure that straightens the anterior teeth without the use of braces or removable aligners. It is the first lingual (behind the teeth) orthodontic treatment modality that incorporates aesthetics, efficiency, and most importantly comfort during the alignment process. This procedure can be used in a variety of clinical situations including minor to moderate tooth movement, relapse from previous orthodontic treatment and as an auxiliary with removable aligner systems.

Concealed & Comfortable

Ultra-thin super-elastic wires are placed and activated on the lingual (behind the teeth) surface of your teeth. Providing a completely invisible orthodontic experience. The relatively flat lingual surface of the anterior teeth makes this procedure possible. The Wirelign® (C5 Hidden Orthodontics) procedure is significantly more comfortable compared to other orthodontic systems. It is a low profile orthodontic system developed without the use of braces/brackets or removable plastic aligners. The bonding material is smoothed over the wires creating a comfortable slight extension of the tooth surface. The low profile and smooth surface makes Wirelign® & ProWire® the most comfortable orthodontic appliance available.

Patented ProWire® System

In addition to the Wirelign® (C5 Hidden Orthodontics) procedure, Dr. Cassalia also developed the patented ProWire® system. The ProWire® system improves treatment outcomes of the Wirelign® procedure as well as other forms of orthodontic treatment, while maintaining the same general principles of aesthetics and comfort as the Wirelign® procedure.

We help to educate and explain

The Wirelign® (C5 Hidden Orthodontics) system was developed to align teeth in a way that is completely invisible and significantly more comfortable. It is a treatment option that won't affect your lifestyle! Wirelign® works very well with the anterior teeth and is not a substitute for full treatment options.
