60_-diamonds l Global Burs

Our dental burs utilize pioneering product design technologies to deliver exceptional performance and durability.

The “More Diamond per Diamond” product design is intended to maximize each Diamond Bur’s longevity and precision. By optimizing diamond crystal exposure and ensuring uniform distribution across the tool surface, this innovative process strengthens the bond and sharpens cutting edges, achieving a remarkable 60% increase in diamond exposure for superior durability and performance.

Triton-coating l Global Burs

To further elevate performance, the advanced “Triton” coating process is applied to reinforce diamond bonding strength, more than doubling durability for smoother, faster cutting that maintains sharpness over extended use. This coating, combined with precisely heat-treated, ground stainless steel shanks, results in tools that perform reliably in high-demand environments while preserving their cutting accuracy and strength.

The Triton bonding process ensures that 60% of each diamond is exposed, with only 40% covered by the bonding agent.

Frequently Asked Questions

Product

What makes the 811S bur ideal for crown preparation and occlusal reduction?

The 811S bur features a flat end barrel shape with a short working length of 4.5mm, providing optimal control when performing occlusal reduction or crown preparations - especially in posterior teeth.

The cylindrical body enables smooth, uniform removal of tooth structure, making it easier to achieve parallel walls and flat surfaces for optimal crown seating.

Why choose a shorter bur like the 811S over a standard length 811?

In clinical scenarios where visibility or access is limited, such as in posterior regions or for pediatric patients, the shorter 811S offers better handpiece maneuverability.

It also reduces the risk of soft tissue trauma and improves tactile control. It’s also useful when working under a microscope or loupe, where precision is key.

Which grit level should I choose for my specific needs?
  • Medium grit (M) is ideal for controlled shaping and minor reductions.
  • Coarse grit (C) is best for faster bulk removal, such as when reducing occlusal height for crowns.
  • Extra Coarse grit (XC) delivers maximum cutting efficiency and is often preferred in lab side adjustments or cases where significant reduction is needed quickly.

Can I use these burs on both natural teeth and restorative materials?

Yes. The 811S is engineered to handle multiple materials, including enamel, dentin, composite resins and even ceramic. This versatility makes it a must have in general, prosthetic and cosmetic dentistry for tasks like refining temporary crowns or prepping porcelain restorations.

How does the short barrel help with heat management and cutting efficiency?

Shorter burs like the 811S generate less vibration and friction than longer burs when used with a light, brushing motion and proper water spray. This leads to less heat production, reducing the chance of pulp damage or iatrogenic trauma during aggressive prep sessions.

How many uses can I expect from each 811S bur?

On average, each bur provides 15 to 20 uses, depending on the grit selected, material being cut, and how it’s maintained. To extend lifespan, always use high speed water cooled handpieces and avoid applying excessive pressure.

In order to achieve this amount of uses of 15-20, we have the following guidelines to be followed:

  • Recommended Speed: 25,000 - 75,000 RPM
  • Maximum Permissible Speed: 120,000 RPM

What are the clinical advantages of the barrel shape versus other bur geometries?

Barrel shaped burs like the 811S are ideal for achieving flat, planar surfaces - unlike round ended or conical burs which may introduce curves or uneven cuts.

The uniform diameter from tip to base ensures parallelism in crown and bridge preps, essential for proper retention and seating.

Are these burs compatible with my handpiece?

Yes. The 811S burs are FG (Friction Grip) type, designed to fit all standard high speed handpieces. Whether you’re in private practice, a dental school, or a specialty clinic, these will seamlessly integrate into your bur block.

What infection control protocols should I follow with these burs?

The 811S burs are fully autoclavable up to 134°C. After each use, they should be thoroughly rinsed, ultrasonically cleaned and sterilized according to standard infection control guidelines.

Proper bur hygiene not only protects patients but extends the life of your instruments.

Why buy from Global Burs instead of other dental suppliers?

At Global Burs, we’re specialists in dental rotary instruments. Our 811S burs are made with multi layered diamond grit for longer cutting life and manufactured under tight ISO tolerances. And in general, our shipping is as fast as it gets and our support team consists of real dental experts who understand your clinical challenges firsthand.
