Types segmentation classifies the burs by geometric design, abrasive grit, and shaft configuration, each sub‑type shaping procurement decisions. Shape sub‑types include round, flame, pear, and football profiles; round burs dominate crown reduction (≈40% of type sales) due to their versatility, while flame and pear designs are preferred for contouring and finishing, collectively representing 35% of the mix. Grit size is divided into coarse, medium, and fine; coarse (30%) is used for rapid bulk removal, medium (45%) balances efficiency and surface smoothness, and fine (25%) serves final polishing and delicate adjustments, influencing lifespan and replacement frequency. Shaft design comprises straight and angled shafts; straight shafts (60%) are standard for most hand‑piece assemblies, whereas angled shafts (40%) address access constraints in posterior regions, affecting inventory complexity. By mapping these sub‑types, the market taxonomy quantifies how product diversity underpins the total addressable market, with each type’s share reflecting procedural demand, tool longevity, and pricing tier.
