Guide Pin Diamond Burs

guide pin diamond burs feature a non-cutting pin that guides the bur along the gingival sulcus, so you get a uniform, well-defined chamfer margin and controlled axial wall reduction on every crown preparation. The design takes the guesswork out of margin placement, keeping cuts consistent from case to case. Available in tapered and cylinder cutting lengths with round end tips, with coarse grit for gross reduction and fine grit for smoothing and finishing, guide pin diamond burs are built for dentists who want a predictable, repeatable chamfer margin.

• Unique, non cutting guide pin allows for precise crown preps
• Ensures a consistent, well defined chamfer margin and axial wall reduction
• Coarse grit for gross reduction, fine grit for smoothing and finishing the preparation
• Tapered, round end and cylinder, round end shapes to match your preferred prep technique
• Offered in 1.4mm, 1.6mm, and 2mm diameters
• FG (friction grip) shank for use in high speed handpieces
• Precision manufactured for consistent, reliable margin definition case after case

What Are Guide Pin Diamond Burs Best Used For?

Guide pin diamond burs are used during crown and bridge preparation to cut a clean, consistent chamfer margin at the gingival sulcus. The non-cutting pin rides along the sulcus as a guide, so the diamond-coated portion of the bur removes tooth structure at a controlled depth and angle instead of relying on freehand technique alone. This makes the bur especially useful for margin definition and axial wall reduction, where a uniform, well-defined margin affects how well the final restoration seats and fits.

What Types of Guide Pin Diamond Burs Does MEISINGER Offer?

Tapered, Round End

The 508 series tapers to a round end, suited to preparations that call for a gradually reducing axial wall alongside the chamfer margin.

Cylinder, Round End

The 509 series holds a consistent diameter along a round cylinder shape, suited to preparations where you want uniform reduction along the length of the cut.

Both shapes are available in coarse grit for initial reduction and fine grit for finishing, in 1.4mm, 1.6mm, and 2mm diameters.

Selecting the Best Guide Pin Diamond Bur for Your Prep

Start with the shape that matches your prep technique. Tapered round end burs suit cases where the axial wall needs to reduce gradually toward the margin, while round cylinder burs hold a consistent diameter for uniform reduction along the wall. From there, choose your diameter based on the margin width the case calls for, 1.4mm, 1.6mm, or 2mm.

Grit selection follows the stage of the prep. Use coarse grit first for gross reduction and initial margin placement, then switch to fine grit to smooth and finish the chamfer margin before impression or scan.

MEISINGER's guide pin diamond burs are manufactured in Germany to the same precision standards as the rest of our diamond bur line, so the guide pin tracks consistently and the margin comes out the same way every time.
