Manufactured from medical-grade stainless steel, the lingual button offers high mechanical strength, corrosion resistance, and biocompatibility suited for prolonged intraoral use. The perforated base increases surface area for adhesive penetration, promoting reliable bonding to tooth surfaces. Available in a standard dimension compatible with contemporary bonding protocols, the lingual button serves as an auxiliary attachment capable of supporting a range of force vectors for space closure, rotational control, or inter-arch mechanics within fixed orthodontic treatment plans.
