Mydent International has introduced two lightweight ceramic bearing high-speed handpieces. The new DEFEND® Handpieces feature a 4-hole quick-release connection with 360-degree swivel to reduce hand fatigue, and push-button cartridge for fast and easy bur changing. One handpiece has a full head size; the other has a mini-head. Replacement turbines with ceramic bearings are available for both versions. DEFEND handpieces combine superior intraoral access and greater visibility with strong, controlled cutting power. The lightweight design provides perfect balance for maximal ergonomics. Operation of 260,000 rpm at 32 psi and ceramic bearings provide smooth, quiet, vibration-free action. DEFEND Handpieces come with a six-month warranty. DEFEND. Works Better. Lasts Longer.
