&NA; Approximately 1/2 of maxillary and 1/5 of mandibular multi‐stranded lingual retainers fail during retention in some form, either bond failure or wire breakage. Memotain is a new CAD/CAM fabricated lingual retainer wire made of custom‐cut nickel‐titanium, as an alternative to multi‐stranded lingual retainers. It offers numerous perceived advantages to the traditional multi‐stranded stainless steel wire, including precision fit, avoidance of interferences, corrosion resistance and even the potential for minor tooth movement as an active lingual retainer. HighlightsA new CAD/CAM fabricated nickel‐titanium retainer is proposed.The retainer is custom cut from nickel‐titanium sheets and electropolished.It enables more precise bonding without occlusal interference or microbial colonization.
