Overview

BioTru is Ormco's conventional (non-self-ligating) ceramic bracket, positioned as an affordable esthetic option combining appearance, function, and strength. Made from 99.9% pure polycrystalline alumina, BioTru provides the translucency patients expect from a ceramic bracket while maintaining stain resistance. The dovetail base design creates an interlocking adhesive interface for maximum bond strength. Precision-cut, diamond-polished slots enhance torque control and sliding mechanics. The design is engineered for straightforward ligation with elastomeric rings and is offered as a cost-effective alternative to Ormco's Damon Clear self-ligating system.

Clinical & technical

Mechanism of action

Standard twin bracket mechanics with elastomeric or SS ligature. The diamond-polished slot surfaces reduce friction during sliding mechanics compared to rough ceramic. Dovetail base geometry creates mechanical interlocking with adhesive for reliable bond throughout treatment, with controlled debonding.

Indications & case selection

Adults and adolescents requesting esthetic brackets at a more accessible price point than monocrystalline or SL ceramic; practices offering a tiered bracket system (BioTru conventional vs. Damon Clear SL); comprehensive fixed appliance cases.

Contraindications & limitations

Conventional ligation means slightly more friction than SL brackets; elastomeric ties stain over time; deep bite cases require assessment; higher cost than metal brackets.
