Frank Dental Set 3 Crown Preparation Kit – PFM, Porcelain-Bonded-to-Metal and Metal Crowns

Professional Crown Preparation with Frank Dental Diamond Burs

The Frank Dental Set 3 Crown Preparation Kit is a specialist dental bur collection designed for clinicians preparing teeth for porcelain-fused-to-metal (PFM), porcelain-bonded-to-metal and full metal crowns. Bringing together carefully selected diamond bur geometries, multiple grit grades and a sterilisation-compatible bur stand, this kit supports the key stages of crown preparation, from initial margin formation through to refinement and contact opening.

Designed for restorative dentistry, the kit combines tapered shoulder burs, modified shoulder burs, parallel chamfer burs, rugby ball burs and flame burs. Each shape serves a particular purpose during preparation, helping clinicians select an appropriate instrument for establishing the required preparation geometry and refining the finished tooth preparation.

The selection includes coarse, medium, fine and extra-fine diamond grits, allowing the clinician to progress from more substantial reduction and margin preparation to controlled finishing. With a selection of bur lengths and cutting profiles, Set 3 provides a practical collection of instruments for clinicians who regularly undertake fixed prosthodontic procedures.

Whether preparing for a conventional PFM restoration or a metal crown, the Frank Dental Set 3 offers a structured selection of burs for common crown preparation stages.

Designed for PFM, Porcelain-Bonded-to-Metal and Metal Crown Preparation

Preparing a tooth for a crown involves more than reducing tooth structure. The clinician must create the appropriate preparation form, establish a suitable finish line, provide adequate restorative space and refine the surfaces to support the intended restoration.

Different restorative materials and crown designs may require different preparation approaches. A porcelain-bonded-to-metal crown combines a metal substructure with a veneering porcelain, while a full metal crown has different restorative space and margin considerations. The preparation design must be selected according to the restoration, tooth position, occlusion and clinical circumstances.

The Frank Dental Set 3 brings together bur designs that can support these preparation stages. Tapered shoulder burs provide options for forming shoulder-style margins, including a square-edge profile and a modified rounded-edge profile. Parallel chamfer burs provide instruments for refining the preparation, while rugby ball and flame shapes offer additional geometries for occlusal contouring and opening proximal contacts.

The inclusion of several grit grades helps the clinician select an appropriate instrument for the stage of treatment. Coarse diamond burs are intended for more efficient material removal, whereas fine and extra-fine burs can be selected for subsequent refinement, subject to the required preparation design and the manufacturer’s instructions.

What’s Included in the Frank Dental Set 3?

The kit contains a selection of diamond burs with different geometries, dimensions and grit grades, supplied with a sterilisable bur stand.

1. D.847.018 Tapered Shoulder Bur – Flat Top, Square Edge

Available in coarse and fine grit

The D.847.018 tapered shoulder bur features a flat top and square-edge profile. It is specified for PFM crown preparation, with a widest diameter of 1.8 mm and a tip diameter of 1.2 mm.

The tapered shoulder geometry provides an instrument for establishing a shoulder-style finish line where that margin design is appropriate to the planned restoration. The flat top and square edge distinguish this bur from a rounded-edge shoulder design, giving clinicians a different cutting profile for preparation work.

The two grit options allow the clinician to select between coarse and fine diamond surfaces according to the task. The coarse version may be selected for more substantial preparation work, while the fine version can be used for refinement where appropriate.

The choice of margin design and bur should always be guided by the clinical case, restorative material, tooth anatomy and the recommended preparation protocol.

2. D.847KR.018 Tapered Shoulder Bur – Modified Shoulder with Rounded Edge

Available in medium and fine grit

The D.847KR.018 is a tapered shoulder bur with a rounded-edge profile, also described as a modified shoulder design. It has a specified tip diameter of 1.2 mm and is available in medium and fine grit.

This geometry provides an alternative to the flat-top, square-edge D.847.018. The rounded-edge profile can be selected when a modified shoulder preparation is indicated by the clinician’s chosen restorative approach.

Having both designs within the same kit gives clinicians flexibility when selecting the bur profile that corresponds to the intended margin configuration. The medium and fine grit options also provide a choice of cutting characteristics for preparation and subsequent refinement.

As with all crown preparation burs, the final margin form must be determined by the restorative requirements and clinical judgement rather than by the instrument alone.

3. Parallel Chamfer Diamond Burs – 1.4 mm Diameter

Available in 10 mm and 11.5 mm lengths, in fine and extra-fine grit

The parallel chamfer burs are included to support refinement of the crown preparation. The kit contains 1.4 mm diameter instruments in two lengths: 10 mm and 11.5 mm. Both lengths are available in fine and extra-fine grit.

A parallel chamfer geometry provides a different cutting profile from the tapered shoulder burs. Depending on the preparation design, these burs can be selected to refine chamfer-style margins and improve the consistency of the prepared surface.

The availability of two lengths offers a choice of working reach and access, depending on the tooth, clinical approach and handpiece positioning. Fine and extra-fine options allow the clinician to select a suitable grade for the finishing stage.

These burs are intended to complement the other instruments in the kit, rather than replace the need to select a margin design appropriate to the planned restoration.

4. Rugby Ball Diamond Burs

Available in medium and fine grit

The rugby ball-shaped diamond burs provide a rounded, elongated working profile for selected crown preparation and contouring tasks.

This shape can be useful when refining curved surfaces and managing transitions between different areas of the preparation. Its rounded profile offers a different approach from the flat-top shoulder and parallel chamfer designs included in Set 3.

The medium and fine grit options provide flexibility according to the amount of refinement required. As with all instruments, clinicians should select the shape, grit and operating technique according to the tooth anatomy, restorative design and manufacturer’s guidance.

5. Flame Diamond Burs

Available in fine grit for opening contacts

The fine-grit flame burs are included for opening proximal contacts during crown preparation.

The slender flame profile is suited to work in narrower areas where access and control are important. It provides a complementary geometry to the broader shoulder and rugby ball burs, allowing the clinician to select an instrument appropriate to the area being treated.

The fine grit is intended for controlled preparation work rather than the more aggressive reduction associated with a coarse diamond. Careful use is essential around adjacent teeth and soft tissues, and appropriate visualisation, access and clinical technique remain important throughout contact opening.

6. Sterilisable Bur Stand

The Frank Dental Set 3 Crown Preparation Kit is supplied with a sterilisable bur stand to help keep the instruments organised between procedures and during instrument processing.

A dedicated stand can make it easier to identify and access the required bur during treatment, while supporting a consistent arrangement of the kit. Follow the stand manufacturer’s instructions and the practice’s validated cleaning, disinfection and sterilisation procedures to ensure the holder is processed appropriately.

A Kit for the Main Stages of Crown Preparation

Set 3 brings together instruments that can be selected across several stages of crown preparation. The sequence below is a general guide to the roles of the different bur types, not a prescribed clinical protocol.

Stage 1: Establishing the Preparation and Margin

The D.847.018 flat-top, square-edge tapered shoulder bur provides an option for establishing a shoulder-style finish line where indicated. Its 1.8 mm widest diameter and 1.2 mm tip diameter give the clinician defined dimensions to consider when selecting the instrument for the intended preparation.

The D.847KR.018 modified shoulder bur offers an alternative rounded-edge profile. The appropriate design depends on the restoration and the clinician’s chosen margin configuration.

Stage 2: Refining the Margin

The parallel chamfer burs are included for preparation refinement. Their 1.4 mm diameter, two working lengths and fine or extra-fine grit choices provide options for different access requirements and finishing tasks.

Selecting a suitable instrument can help the clinician work consistently along the intended finish line while maintaining awareness of the required preparation geometry.

Stage 3: Contouring and Surface Refinement

The rugby ball burs provide a rounded shape for selected contouring and refinement tasks. The medium and fine grit choices allow selection according to the clinical stage and the amount of material that needs to be removed.

Stage 4: Opening Proximal Contacts

The fine-grit flame burs provide a more slender profile for opening proximal contacts. This complements the other bur geometries in the set and provides an instrument specifically identified for this part of the preparation process.

The sequence and instruments used will vary according to the tooth, restorative material, existing anatomy and clinical circumstances.

Why Choose the Frank Dental Set 3 Crown Preparation Kit?

A Selection of Purposeful Bur Geometries

The kit combines tapered shoulder, modified shoulder, parallel chamfer, rugby ball and flame shapes. This gives clinicians a range of profiles for different aspects of crown preparation without relying on a single bur design for every task.

Options for Different Margin Designs

The inclusion of both flat-top, square-edge and rounded-edge shoulder burs provides a choice of margin profiles, subject to the preparation design required for the planned restoration.

Multiple Grit Grades

Coarse, medium, fine and extra-fine options allow clinicians to select an appropriate grit for the stage of treatment. The exact role of each instrument should be determined by the preparation requirements and the manufacturer’s guidance.

Two Parallel Chamfer Bur Lengths

The 10 mm and 11.5 mm parallel chamfer options provide a choice of working length. This can be useful when considering access, reach and the tooth being prepared.

Dedicated Contact-Opening Burs

Fine-grit flame burs are included for proximal contact opening, providing a slender instrument geometry alongside the broader shoulder and rugby ball burs.

Organised Instrument Storage

The supplied sterilisable bur stand helps keep the kit arranged and supports instrument management in the dental practice. Always follow the applicable instructions for cleaning and sterilisation.

Who Is the Set 3 Crown Preparation Kit For?

The Frank Dental Set 3 is intended for dental professionals undertaking fixed prosthodontic procedures involving PFM, porcelain-bonded-to-metal and metal crowns.

It may be suitable for:

• General dental practitioners preparing teeth for full coverage crowns.
• Restorative dentists working with conventional metal-based crown restorations.
• Clinicians who require both square-edge and rounded-edge shoulder bur options.
• Dental practices seeking a coordinated selection of crown preparation burs.
• Practices looking to organise commonly used preparation instruments in a dedicated kit.

The most appropriate instruments will depend on the clinical case, the chosen restorative material, the required preparation design and the clinician’s training.

Selecting the Correct Bur for the Procedure

Bur selection should take into account the intended finish-line design, the amount of tooth structure requiring reduction, the access available and the stage of preparation.

A coarse diamond may be appropriate for a stage requiring more efficient material removal, while medium, fine or extra-fine grades may be selected for other preparation and refinement tasks. The geometry is equally important: a flat-top square-edge shoulder bur, a rounded-edge modified shoulder bur, a parallel chamfer bur, a rugby ball and a flame bur do not serve identical purposes.

Use each bur in accordance with the manufacturer’s instructions, including recommended operating speed, cooling requirements and permitted handpiece compatibility. Avoid excessive pressure, inspect instruments before use and replace burs that are damaged, worn or no longer cut effectively. Appropriate irrigation and safe clinical technique are essential during tooth preparation.

Cleaning, Sterilisation and Bur Care

The sterilisable bur stand helps keep the kit organised, but it does not remove the need to process each instrument correctly. Burs and the stand should be cleaned, inspected and sterilised in accordance with their respective manufacturers’ instructions and the practice’s validated infection-control procedures.

Before each use, check the burs for visible damage, wear or contamination. Ensure that each bur is securely fitted into the appropriate handpiece and that the instrument is suitable for the intended procedure. Follow the manufacturer’s guidance for speed, cooling and operating technique, and do not use a bur beyond its intended service life.

Proper instrument maintenance supports consistent clinical workflow and helps practices manage their instruments responsibly.
