Overview

Ortho Technology's PURE Sapphire bracket system uses monocrystalline alumina — the same crystal structure as synthetic sapphire — to produce the clearest available esthetic bracket. Monocrystalline alumina transmits light differently from polycrystalline alumina (PCA), giving it superior optical transparency. Each PURE bracket is diamond and heat polished with rounded, smooth corners. The bonding base is coated with aluminum oxide spheres, creating millions of mechanical undercuts that lock with adhesive for secure retention while allowing predictable debonding at treatment end.

Clinical & technical

Mechanism of action

Standard twin bracket mechanics — the archwire is engaged in the slot and ligated with elastomeric rings or SS ligatures. No self-ligation. Conventional wire progression from light NiTi to rectangular SS. The monocrystalline structure makes the bracket mechanically stronger against torque fracture than PCA brackets.

Indications & case selection

Adult patients demanding maximum esthetic clarity; high visibility anterior teeth where standard PCA brackets are insufficiently clear; patients willing to pay a premium for the clearest available esthetic bracket.

Contraindications & limitations

More expensive than PCA ceramic; monocrystalline brackets can be harder to debond predictably — the alumina oxide sphere base addresses this but requires care; no self-ligation (elastomeric ligatures required — some staining risk).

Design & fabrication

Components & materials

• Monocrystalline alumina crystal bracket body (diamond and heat

polished)

• Small, low-profile bracket design
• Aluminum oxide sphere-coated bonding base
• Standard twin bracket geometry with tie wings
• Available in Roth, MBT, and other standard prescriptions

Lab fabrication notes

Manufactured by Ortho Technology — not lab-fabricated. Lab involvement in indirect bonding tray fabrication only.

Common variants & modifications

• Radiance Plus — American Orthodontics monocrystalline sapphire

bracket Radiance Plus brackets

• Clarity Advanced — 3M PCA ceramic bracket
• Damon Clear — Ormco PCA self-ligating ceramic Damon Clear

Common variants & modifications

• Monocrystalline vs. polycrystalline: Pure (American

Orthodontics) is monocrystalline; polycrystalline versions (Inspire Ice, Transcend) offer lower cost with slightly less translucency

• Pure with metal slot: ceramic body with metal slot liner;

reduces friction while maintaining esthetic appearance

• Pure Mini: reduced-profile version for smaller teeth
• Self-ligating sapphire: Clarity SL / Empower Clear — passive

clip on sapphire body; combines self-ligation with sapphire esthetics

• Sapphire in hybrid arch: sapphire on upper anteriors only, metal

on posterior and lower teeth
