Key Features
🛡️ Clinical-Grade Zero Retraction System
Cross-infection is one of the biggest challenges in dental clinics. The T7L features a comprehensive zero-retraction system that blocks backflow completely. By avoiding impurities, debris, and oral fluids from entering the internal cartridge, it ensures a safer sterile environment and prolongs the service life of the turbine bearings.
⏱️ Safe Braking: 1-Second Quick Stop
Equipped with a highly responsive mechanical braking system, the T7L shuts down rotation safely within just 1 second after releasing the foot control. This quick-stop capability prevents accidental soft-tissue damage during intricate dental preparation procedures.
💡 Shadowless Visual Comfort (≥12,000 Lux)
Featuring an integrated premium light guide, the handpiece outputs a powerful illumination of over 12,000 Lux. This enhanced brightness mirrors natural daylight, offering dental surgeons a high-definition, glare-free operational window even in the deep oral cavity.
