The W&H Synea / Surgical WS-91 LG 1:2.7 Speed-Increasing Surgical Handpiece (Ref: 30048000) is a 45-degree angled, 1:2.7 speed-increasing surgical contra-angle handpiece equipped with self-generating Mini LED+ illumination and an external spray clip system, engineered for deep wisdom tooth sectioning, apical resections, and precise bone cuts.
Key Features
-
Self-Generating Mini LED+ Illumination: Integrated generator produces bright, daylight-quality Mini LED+ light independently without requiring a lit motor coupling.
-
45-Degree Angled Head Geometry: Provides optimum access and visibility to hard-to-reach posterior sites, specifically impacted third molars.
-
1:2.7 Speed-Increasing Transmission: Multiplies motor output speed by 2.7 times (up to 135,000 RPM bur speed) to deliver rapid, clean tooth sectioning without stall.
-
Triple Spray Coolant System (External Clip): External irrigation tube directs sterile saline spray precisely to the cutting tip to prevent tissue necrosis and bone thermal trauma.
-
Surgical Stainless Steel Housing: Scratch-resistant, corrosion-proof body built to withstand high-level disinfection and repeated steam sterilization.
Clinical Indications
-
Impacted Third Molar Extractions: Rapid sectioning of crowns and roots in deep mandibular and maxillary wisdom tooth impactions under direct LED light.
-
Apicoectomies & Osteotomies: Bone removal, apical resections, and minor oral surgery requiring high speed, clear illumination, and precise saline irrigation.
