The MDK 1:1 Contra Angle Non-Optic Handpiece is a dental instrument used primarily in various dental procedures such as restorative work, prosthodontics, and general desntistry. The “1:1” ratio provides a 1:1 transmission of speed and torque, offering precise control and adequate power for various dental procedures. This handpiece has a contra-angle configuration, commonly used in procedures where direct access to the treatment site is challenging, such as posterior teeth or areas obstructed by other dental structures. The handpiece is equipped with an external spray system that delivers a continuous flow of water or cooling solution to the treatment site. This helps to irrigate and cool the area, reducing heat generated by friction during procedures and minimizing the risk of thermal damage to the tooth structure. It also features a push-button chuck mechanism allows for quick and easy insertion and removal of dental burs and rotary instruments. With a simple push of a button, the chuck securely holds the instrument in place, facilitating efficient instrument changes during procedures. Ergonomically designed with high-quality stainless steel, this handpiece is durable, comfortable, long-lasting and can be sterilized.
