- A professional rotary dental instrument designed for precise contouring, shaping, and refining of dental restorative materials
Uses
- Large Restorative Shaping:
- Used to efficiently contour and anatomical map larger composite fillings, amalgams, or temporary crown materials
- Posterior Occlusal and Lingual Finishing:
- Specifically suited for polishing and shaping the broader grooves, pits, and structural curves of rear molars (chewing and tongue-facing sides)
- Margin Alignment and Refinement:
- Shaves down sharp transitions between restorative materials and natural enamel to create a flush, plaque-resistant margin
- Bulk Flash Clean-up:
- Quickly removes macro excess composite material or bonding resins away from tooth structures following curation
Features
- 12-Blade Flute Geometry:
- Employs a 12-blade configuration that shaves material smoothly rather than cutting aggressively, leaving a pre-polished finish
- Egg / Football Shape (#7406):
- Built with an enlarged rounded geometry (1.8mm diameter x 3.4mm length) that naturally conforms to the wider anatomy of posterior teeth
- Friction Grip (FG) Shank:
- Designed with a standard-length friction grip shank for seamless, tight compatibility with standard high-speed handpieces
- Gold-Plated Coating:
- The shank features premium gold plating to increase internal handpiece friction grip and offer a chemical-resistant shield
- High-Density Tungsten Carbide:
- Engineered using durable, fine-grain tungsten carbide to preserve sharp cutting surfaces across multiple procedures
- 100% Autoclavable:
- Fully safe for standard chemical or steam-heat autoclave cycles without losing structural integrity
Benefits
- Faster Polishing Workflows:
- The 12-blade layout leaves restorations highly refined, allowing clinicians to bypass or drastically reduce secondary rubber or paste polishing stages
- Corrosion Resistance:
- Gold plating effectively prevents oxidation, rust, and chemical damage caused by repeated cleaning cycles
- Increased Working Efficiency:
- The slightly larger head size of the #7406 handles broader surface boundaries at once, reducing patient chair time
- Exceptional Quality Control:
- Manufactured to align with name-brand dimensions like the Midwest 7406 series, it offers clinical consistency at a lower price point
