Tungsten carbide retention bur – serrated wheel bur for tooth-to-acrylic bonding
The DLG tungsten carbide retention bur is designed to quickly create retention grooves in acrylic denture teeth used in dental prosthetics.
Its serrated wheel geometry creates regular retentions to improve the mechanical bond between the acrylic denture tooth and the acrylic resin base during denture set-up, relining, repair or complete denture fabrication.
With its standard 2.35 mm shank, it is compatible with suitable dental laboratory handpieces and integrates easily into the dental technician’s workstation.

Set-up, relining and repair
A bur designed to reinforce the tooth-to-acrylic interface
During denture set-up or repair, the bond between the acrylic denture tooth and the acrylic base must be reliable. A surface that is too smooth may limit the mechanical retention of the resin.
The retention bur allows the dental technician to quickly create grooves in the acrylic tooth in order to increase the available mechanical anchorage areas.
This preparation helps promote stronger retention during relining, repair or placement of acrylic teeth on a complete denture.
Serrated wheel for fast and consistent retentions
The serrated wheel geometry makes it possible to cut regular grooves into the acrylic denture tooth with a simple and repeatable movement.
It automatically creates circular retention grooves, useful for improving the mechanical retention of the acrylic resin during assembly.
This shape is particularly practical for saving time and achieving a consistent result from one tooth to another.
Tungsten carbide for long-lasting cutting performance
Tungsten carbide provides good wear resistance and helps maintain a clean cut during repeated work on acrylic denture teeth.
This material is suitable for rotary dental laboratory instruments used for frequent preparation, adjustment or retention-groove creation.
To preserve the cutting efficiency of the bur, regular cleaning is recommended, while avoiding excessive pressure during use.
Applications in the dental prosthetics laboratory
Acrylic denture teeth
Creation of retention grooves in acrylic teeth before set-up or repair.
Relining
Mechanical preparation to improve retention during acrylic denture relines.
Prosthetic repairs
Preparation of teeth or acrylic areas before assembly, addition or material adjustment.
Complete dentures
Reinforcement of mechanical retention between acrylic teeth and the denture base.
Benefits of the DLG retention bur
Regular retentions
The serrated wheel creates consistent grooves on acrylic denture teeth.
Time saving
A single movement quickly prepares the tooth before bonding, repair or relining.
Improved retention
The grooves increase mechanical anchorage between the acrylic tooth and the acrylic base.
Laboratory compatibility
Ø 2.35 mm shank compatible with suitable dental laboratory handpieces.
Recommended instructions for use
- Hold the acrylic denture tooth firmly before preparation.
- Insert the retention bur into a compatible Ø 2.35 mm laboratory handpiece.
- Check that the bur is securely tightened before starting.
- Position the serrated wheel on the area to be prepared.
- Apply light circular pressure without forcing.
- Allow the bur to create the retention grooves evenly.
- Remove acrylic dust and debris after milling.
- Proceed with resin application and assembly according to the laboratory protocol.
Best practices for use
- Hold the acrylic denture tooth securely during cutting.
- Work with light, even pressure.
- Clean the prepared area before applying acrylic resin.
- Visually check the regularity of the grooves.
- Use suitable suction for acrylic dust.
- Clean the bur after use to preserve cutting quality.
Mistakes to avoid
- Applying excessive force to the acrylic tooth.
- Using the bur while the tooth is poorly secured.
- Creating grooves that are too deep if the tooth is thin.
- Failing to remove acrylic dust before assembly.
- Using a handpiece that is not compatible with the Ø 2.35 mm shank.
- Confusing retention grooves with aesthetic finishing.
Comparison: manual retention preparation vs serrated wheel bur
| Criterion | Manual preparation | Serrated wheel retention bur |
|---|---|---|
| Regularity | Variable depending on the technique and the instrument used. | More homogeneous and repeatable circular grooves. |
| Preparation time | Longer if each retention is prepared separately. | Fast creation of retentions with one controlled movement. |
| Mechanical retention | Depends on the depth and shape of the retentions. | Serrated geometry designed to optimise the tooth-to-acrylic anchorage. |
| Reproducibility | More operator-dependent. | More consistent result from one tooth to another. |
| Laboratory use | Possible, but less efficient for series work. | Practical for complete dentures, repairs and relines. |
| Working comfort | May require several manipulations. | Simple gesture with a dedicated serrated wheel. |

FAQ – Tungsten carbide retention bur
Is this bur suitable for standard acrylic denture teeth?
Yes, it is designed to create retentions in acrylic denture teeth used in removable prosthetics.
The grooves help improve mechanical retention between the tooth and the acrylic resin during relining, repair or denture set-up.
How many grooves does the bur create?
The serrated wheel creates 4 circular retention grooves in the acrylic denture tooth.
These grooves support a regular preparation before assembly with acrylic resin.
Can the bur be used with a standard laboratory handpiece?
Yes, the bur has a Ø 2.35 mm shank, the standard diameter for compatible dental laboratory handpieces.
Always check that the bur is correctly tightened before use.
Does the tungsten carbide wheel wear quickly?
Tungsten carbide provides good wear resistance when working on acrylic denture teeth.
Service life depends on the workload, pressure applied, cleaning and maintenance of the instrument.
Does this bur replace the acrylic assembly protocol?
No. The bur mechanically prepares the tooth by creating retentions.
The laboratory must then follow its acrylic resin, cleaning, bonding, repair or relining protocol.
