Slow Speed Handpieces: Features And Advantages
Slow speed handpieces are invaluable companions for intricate and delicate dental work, offering distinctive features and advantages that cater to specialized procedures.
Optimal Precision And Control
Slow speed handpieces operate at lower RPMs, providing dentists with better precision and control. These handpieces are perfect for precise detailing activities such as polishing dental restorations, finishing surfaces, and adjusting crowns or bridges. The slower rotation allows dentists to make precise adjustments with ease.
Reduced Heat Generation
One of the significant benefits of slow speed handpieces is their ability to generate less heat during dental procedures. Lowering the RPM reduces friction and heat accumulation, lowering the danger of thermal injury to tooth tissues. Slow speed handpieces are therefore ideal for treatments involving sensitive regions.
Smooth And Quiet Operation
Slow speed handpieces operate with a smooth and gentle motion, resulting in minimal vibrations and noise. This makes treatments more comfortable for both the dentist and the patient, providing a peaceful and stress-free environment in the dental office.
Ideal For Polishing And Finishing
Polishing and finishing procedures require attention to detail and a light touch. Slow speed handpieces are appropriate for such activities because they enable dentists to obtain a high-quality finish on dental restorations, crowns, and other prosthetic work.
Versatility With Attachments
Similar to high speed handpieces, slow speed handpieces also come with a range of attachments to cater to various dental procedures. From polishing cups and prophy angles to latch-type and friction grip burs, these handpieces can adapt to different clinical needs with ease.
