The W&H WS-91 LG Mini LED+ is the ultimate solution for complex posterior oral surgery, completely eliminating the dark shadows and restricted access associated with third molar extractions. As an advanced LED 45-degree surgical handpiece, it merges the accessibility of an angled head with brilliant, daylight-quality illumination—generated entirely within the instrument itself.

Equipped with an innovative internal micro-generator, this self-illuminating surgical handpiece produces its own power for the Mini LED+, providing perfect visibility without requiring an optic-enabled surgical motor. Paired with a 1:2.7 speed increasing ratio that drives cutting speeds up to 135,000 RPM, it allows for incredibly fast and precise tooth sectioning in the retromolar region. Fully dismantlable and built for rigorous infection control, the WS-91 LG is the definitive tool for efficient, trauma-free extractions.

Independent Mini LED+ Illumination: A built-in generator powers the LED independently of your surgical motor, flooding the darkest regions of the oral cavity with high-contrast, daylight-quality light.
Innovative 45-Degree Head: The specialized angulation maximizes your field of vision and allows direct, ergonomic access to impacted wisdom teeth without excessive cheek retraction.
1:2.7 Speed Increasing Ratio: Converts standard motor speeds into high-velocity cutting power (up to 135,000 RPM), allowing the bur to glide effortlessly through dense enamel and bone.
Triple Spray Cooling: High-speed sectioning demands superior cooling. A precision triple spray directs coolant exactly to the cutting edge, effectively neutralizing heat and preventing thermal necrosis.
Tool-Free Dismantlability: Sterile processing staff can easily dismantle the entire handpiece in seconds without tools, ensuring comprehensive internal cleaning and extending the instrument's longevity.
Secure Friction Grip (FG) Chuck: The push-button mechanism securely holds surgical-length FG burs (up to 25 mm), ensuring maximum stability and run-out accuracy under high rotational speeds.

Clinical Applications

The WS-91 LG is an advanced LED 45-degree surgical handpiece designed specifically for heavily shadowed, hard-to-reach posterior applications:

Surgical extraction of impacted third molars (wisdom teeth)
Rapid tooth separation and sectioning in dark visual fields
Apical resections in the posterior maxilla and mandible
High-speed bone removal in areas with restricted access
