Frank Dental STT Soft Tissue Trimming Burs

Yttrium-Stabilised Zirconia Soft Tissue Management Burs for Gingival Contouring, Tissue Trimming and Impression Optimisation

Advanced Soft Tissue Trimming Without Electrosurgery or Lasers

The Frank Dental STT Soft Tissue Trimming Bur is an innovative soft tissue management instrument manufactured from high-strength yttrium-stabilised zirconia (Y-TZP). Designed specifically for the controlled trimming, contouring and management of gingival soft tissues, the STT bur allows clinicians to achieve precise soft tissue modification while simultaneously creating haemostasis through thermal coagulation.

Unlike conventional diamond burs, carbide burs or rotary instruments intended for hard tissue, the Frank Dental STT bur has been specifically engineered for use on soft tissue. When operated correctly at approximately 300,000 rpm, without coolant and using light pressure, the bur gently trims gingival tissue while generating sufficient frictional heat to coagulate blood vessels.

This unique mechanism helps provide:

• Simultaneous tissue trimming and coagulation
• Reduced bleeding
• Improved visibility
• Faster soft tissue management
• Better impression taking conditions
• Improved digital scanning access

For dentists searching for a soft tissue trimming bur, gingival contouring bur, zirconia soft tissue bur, gingivectomy bur, crown lengthening bur, soft tissue management bur, gingival recontouring bur or implant tissue shaping bur, the Frank Dental STT represents a simple, predictable and highly effective solution.

What is a Soft Tissue Trimming Bur?

The Frank Dental STT is a rotary soft tissue management bur manufactured from yttrium-stabilised zirconia.

Unlike conventional burs designed to cut enamel, dentine or restorative materials, the STT bur is specifically intended for soft tissue applications.

The specially engineered zirconia working surface allows clinicians to:

• Trim gingival tissues
• Recontour gingival architecture
• Expose preparation margins
• Shape peri-implant tissues
• Improve emergence profiles
• Optimise access for impressions and digital scans

The bur works through controlled friction rather than aggressive cutting.

What is Yttrium-Stabilised Zirconia?

Yttrium-stabilised zirconia (Y-TZP) is one of the strongest ceramic materials used in dentistry.

It is commonly found in:

• Zirconia crowns
• Implant components
• Surgical instruments
• Precision dental devices

Its unique properties make it ideal for soft tissue trimming burs because it offers:

• High strength
• Exceptional wear resistance
• Smooth tissue interaction
• Excellent thermal stability
• Controlled heat generation

These characteristics allow the STT bur to interact predictably with soft tissues while maintaining excellent durability.

How Does the Frank Dental STT Bur Work?

The STT bur works differently from traditional surgical instruments.

The bur must be used:

At Approximately 300,000 RPM

High rotational speed is essential for efficient tissue trimming and coagulation.

Without Water Coolant

Unlike conventional crown preparation burs, coolant must not be used.

Water spray prevents the heat generation required for coagulation.

With Light Pressure

Only light pressure should be applied.

The bur is designed to gently interact with soft tissue rather than aggressively cut it.

When used correctly, the rotating zirconia surface creates controlled friction against the tissue.

This friction generates heat.

As the soft tissue is trimmed, the heat simultaneously coagulates small blood vessels.

The result is a remarkably clean surgical field with minimal bleeding.

---

Simultaneous Trimming and Coagulation

One of the major advantages of the Frank Dental STT bur is its ability to perform two procedures at the same time.

Soft Tissue Trimming

The rotating zirconia bur gently removes unwanted tissue.

Thermal Coagulation

The frictional heat generated during rotation causes coagulation of small blood vessels.

This creates:

• Reduced bleeding
• Improved visibility
• Cleaner margins
• Enhanced access

The ability to trim and coagulate simultaneously can significantly simplify soft tissue management procedures.

---

Why is Haemostasis Important?

Effective haemostasis is critical during many restorative and prosthetic procedures.

Excessive bleeding can interfere with:

• Digital impressions
• Conventional impressions
• Crown preparations
• Veneer preparations
• Implant impressions
• Restorative procedures

The Frank Dental STT helps control bleeding as tissue is modified, allowing clinicians to maintain a clearer working field.

This can improve procedural efficiency and restorative accuracy.

---

Applications in Crown and Bridge Dentistry

One of the most common uses of the STT bur is exposing crown margins.

Subgingival preparation margins can be difficult to visualise during:

• Crown preparations
• Impression taking
• Digital scanning

The STT allows gentle tissue modification around the preparation margin to improve access and visibility.

Benefits include:

• Improved margin access
• Better impression accuracy
• Enhanced digital scanning
• Reduced need for retraction cords

---

Soft Tissue Management Around Implants

Peri-implant soft tissue management plays an important role in achieving aesthetic implant restorations.

The Frank Dental STT can be used to:

• Refine gingival contours
• Shape soft tissue emergence profiles
• Improve implant aesthetics
• Enhance access during impression taking

This can be particularly useful when creating natural-looking implant restorations in the aesthetic zone.

---

Gingival Recontouring and Smile Design

Modern aesthetic dentistry frequently requires minor gingival modifications.

The STT bur is ideal for:

Gingival Recontouring

Creating more symmetrical gingival margins.

Smile Design Procedures

Improving the relationship between teeth and soft tissues.

Crown Lengthening Adjustments

Minor tissue modification to improve restorative outcomes.

Aesthetic Gingivoplasty

Refining gingival architecture for cosmetic enhancement.

---

Advantages Over Traditional Electrosurgery

Many clinicians use electrosurgery for soft tissue management.

The Frank Dental STT provides several advantages:

Familiar Handpiece Use

Operates using a conventional high-speed handpiece.

No Additional Equipment

No electrosurgical unit required.

Precise Tissue Control

Excellent tactile feedback.

Reduced Complexity

Simple and intuitive technique.

Cost Effective

No investment in dedicated soft tissue equipment.

---

Advantages Over Laser Soft Tissue Systems

Dental lasers can be highly effective but may require significant investment and training.

The STT bur offers:

• Immediate integration into existing workflows
• Familiar rotary instrumentation
• Minimal learning curve
• Lower equipment costs
• Excellent clinical control

For many practices, the STT provides an accessible alternative for routine soft tissue procedures.

---

Clinical Protocol

For optimum results Frank Dental recommends:

Speed

Approximately 300,000 rpm.

Coolant

No water spray.

Pressure

Light contact pressure only.

Movement

Continuous sweeping motion.

Visibility

Maintain excellent visual control throughout the procedure.

Using excessive pressure is unnecessary and may reduce efficiency.

The bur performs best when allowed to work through controlled friction and rotational speed.

---

Benefits for Digital Dentistry

Digital workflows require clear visibility of restoration margins.

The Frank Dental STT helps improve:

• Margin exposure
• Scanner access
• Tissue management
• Digital impression accuracy

Compatible with all major intraoral scanner systems including:

• Trios
• iTero
• PrimeScan
• Medit
• CEREC

The STT can help create ideal soft tissue conditions before digital scanning.
