⁠Bondable Lingual Buttons (Round base )

Bondable lingual buttons are small, round-shaped devices made of metal (often stainless steel) or other materials, which are bonded directly to the lingual surface (inner side) of the teeth using orthodontic adhesive.
The round base refers to the shape of the button, which is typically smooth and circular, providing a stable and reliable bonding surface for attachment.
The buttons may have a small loop or eyelet on top, which can be used to attach elastic bands, springs, or other orthodontic auxiliaries.
