The Types dimension of the market taxonomy distinguishes four principal metal ligature families, each with distinct sub‑categories that influence pricing and adoption rates. Stainless‑steel ligatures are the baseline product, offered in standard, pre‑torqued, and heat‑treated variants; they dominate cost‑sensitive segments and support roughly 40 % of overall sales. Nickel‑titanium (NiTi) ligatures provide superelastic properties and are supplied as conventional, low‑profile, and coated (e.g., TiN) forms, capturing about 30 % of the market due to their superior force‑delivery consistency. Elastomeric‑metal hybrid ligatures combine a metal core with an elastomeric sheath, available in single‑strand, braided, and multi‑core designs, representing approximately 20 % of revenue as they balance flexibility with metal strength. Finally, self‑ligating bracket mechanisms incorporate integrated metal clips or doors, classified as passive, active, or torque‑adjustable, and account for the remaining 10 % of market volume. The distribution of these types aligns with clinical preference, regulatory constraints, and cost considerations, collectively defining the market’s structural composition.
