Product Overview – Frank Dental 856.012

The Frank Dental 856.012 is designed for professional dental applications where a tapered chamfer preparation instrument with a relatively narrow rounded tip is required.

Key product features:

• Manufacturer: Frank Dental, Germany
• Product code: 856.012
• Instrument type: Diamond dental bur
• Shape: Tapered chamfer
• Working end: Round end
• Tip diameter: 0.75mm
• Primary application: Dental crown preparation
• Clinical use: Axial reduction, chamfer margin preparation and restorative preparation refinement
• Suitable applications: Fixed prosthodontics and indirect restorative dentistry

Its carefully selected geometry makes the 856.012 particularly useful when clinicians require a tapered instrument capable of creating a controlled chamfer finish line without using an unnecessarily wide preparation profile.

Understanding the Tapered Chamfer Design

The tapered chamfer diamond bur is one of the most frequently selected instrument shapes in restorative dentistry.

Its geometry allows clinicians to prepare the axial walls of a tooth while developing a defined cervical finish line. The taper provides a controlled transition between the prepared tooth structure and the intended restorative margin.

The Frank Dental 856.012 incorporates this familiar preparation geometry with a rounded working end and a 0.75mm tip diameter.

The tapered profile can assist with:

• Establishing consistent axial wall reduction.
• Creating a defined chamfer finish line.
• Maintaining controlled preparation geometry.
• Refining the transition between axial and cervical surfaces.
• Supporting the preparation of indirect restorations.
• Improving access when working around the cervical margin.

The rounded end is an important feature of the instrument. Rather than producing a sharp internal transition, the round-ended profile can help create a rounded internal preparation geometry when used with appropriate clinical technique.

This is particularly relevant when preparing teeth for contemporary ceramic restorations, where preparation design, material thickness and internal geometry must be considered together.

Why Choose a 0.75mm Tip Diameter?

The 0.75mm tip diameter is an important feature of the Frank Dental 856.012.

Choosing the correct bur diameter is essential when planning crown preparations because the working-end dimensions influence the preparation profile and the amount of tooth structure removed.

A 0.75mm tip offers a relatively narrow preparation profile compared with larger tapered chamfer instruments.

This can be particularly useful when clinicians want to maintain a controlled chamfer margin and avoid unnecessarily increasing the width of the cervical preparation.

The narrow tip can also provide greater flexibility when working in areas where access and preparation dimensions need careful consideration.

For clinicians developing a consistent crown preparation protocol, having different tapered chamfer diameters available allows the instrument to be selected according to the restorative material, tooth anatomy and required preparation design.

The 856.012 is therefore a useful option for dental professionals looking for a narrower tapered chamfer diamond bur.

Applications in Modern Crown Preparation

Crown preparation is a fundamental part of restorative dentistry. The quality of the preparation has an important influence on the fit, function and appearance of the final restoration.

A carefully prepared tooth must provide sufficient restorative space while maintaining appropriate axial wall geometry, margin definition and retention characteristics.

The Frank Dental 856.012 can be incorporated into crown preparation workflows where a tapered chamfer instrument with a rounded end is required.

1. All-Ceramic Crown Preparation

All-ceramic restorations require careful consideration of preparation geometry and material thickness.

The Frank Dental 856.012 can be used as part of a preparation sequence to establish the required axial reduction and chamfer margin, according to the selected ceramic system and the clinician’s preferred preparation technique.

A controlled preparation helps provide the dental laboratory with a clearly defined margin from which to manufacture the restoration.

2. Zirconia Crown Preparation

Zirconia crowns are widely used in modern restorative dentistry because of their mechanical properties and versatility.

When preparing teeth for monolithic zirconia crowns, clinicians must follow the preparation recommendations for the specific zirconia material being used.

The tapered chamfer profile of the Frank Dental 856.012 makes it a useful instrument for developing preparation geometry where a chamfer margin is indicated.

Its 0.75mm tip diameter provides a narrower working profile for clinicians who require controlled margin preparation.

3. Lithium Disilicate Restorations

Lithium disilicate is frequently selected for crowns and other indirect restorations where strength and aesthetics are important.

Preparation requirements vary according to the restoration design and manufacturer’s recommendations.

The Frank Dental 856.012 can form part of a preparation sequence for clinicians working with lithium disilicate restorations, helping establish the appropriate axial and cervical preparation contours.

4. Porcelain-Fused-to-Metal Crowns

Porcelain-fused-to-metal restorations continue to have an important place in restorative dentistry.

The tapered chamfer design can be incorporated into preparation protocols where a chamfer margin is appropriate for the intended restoration.

The 856.012 provides a narrow rounded-end option for clinicians preparing teeth for metal-ceramic restorations.

5. General Fixed Prosthodontics

Beyond individual crown preparations, tapered chamfer diamond burs are useful throughout fixed prosthodontic dentistry.

The Frank Dental 856.012 can be considered for selected preparation and refinement stages where its dimensions and geometry are appropriate.

The Importance of a Defined Chamfer Margin

The finish line is one of the most important aspects of any crown preparation.

A clearly defined margin helps the dental laboratory identify the preparation boundary and manufacture a restoration that follows the intended preparation design.

Poorly defined margins can make impression taking, digital scanning and laboratory communication more challenging.

A tapered chamfer diamond bur provides a practical way of establishing a smooth, continuous preparation margin when used correctly.

The Frank Dental 856.012 offers a 0.75mm rounded-end profile for clinicians seeking a narrower chamfer preparation instrument.

The objective is to create a consistent finish line that is appropriate for the restorative material while preserving as much healthy tooth structure as clinically possible.

The rounded end can also help reduce the likelihood of creating an unnecessarily sharp internal transition, provided the instrument is used with appropriate orientation and pressure.
