Edenta TC390S Composite S-Finisher – Advanced Flame-Shaped Tungsten Carbide Finishing Bur for Composite Restorations

The Ultimate Flame-Shaped Composite Finishing Bur for Anterior and Interproximal Composite Refinement

The Edenta TC390S S-Finisher is a premium Swiss-manufactured tungsten carbide finishing bur designed specifically for the shaping, contouring and finishing of modern composite restorations. Featuring Edenta’s innovative S-Finisher technology and a precision-engineered 12-blade flame-shaped design, the TC390S enables clinicians to efficiently refine composite restorations while producing an exceptionally smooth surface that significantly reduces the need for multiple finishing steps.

Traditionally, composite finishing required multiple finishing instruments to progressively improve surface quality. The development of Edenta’s S-Finisher system has transformed this workflow, allowing dentists to achieve outstanding surface smoothness in just two finishing stages when combined with an ultra-fine white band finisher. This streamlined approach saves valuable chairside time while improving the overall quality of composite restorations.

Whether you are placing direct composite veneers, performing composite bonding, refining Class III restorations, finishing interproximal composite restorations or completing aesthetic smile makeover cases, the Edenta TC390S provides exceptional control, cutting efficiency and surface quality.

What Is the Edenta TC390S?

The Edenta TC390S is a flame-shaped tungsten carbide S-Finisher designed for composite finishing procedures. The instrument features 12 precision-ground blades and a specialised cross-cut geometry developed specifically for composite restorative materials. The innovative blade design optimises cutting efficiency while simultaneously producing a remarkably smooth restoration surface.

The flame shape makes the TC390S particularly effective for:

• Facial surface refinement
• Interproximal finishing
• Cervical margin finishing
• Composite bonding procedures
• Veneer contouring
• Emergence profile refinement
• Composite margin blending
• Anterior composite restorations

Its slender profile allows excellent access to difficult areas while maintaining exceptional visibility and control throughout the finishing procedure.

The Evolution of Composite Finishing

For many years, composite finishing involved multiple sequential steps using standard, fine and ultra-fine finishing burs.

A traditional workflow often required:

Step 1

Standard carbide finisher

Step 2

Fine carbide finisher

Step 3

Ultra-fine carbide finisher

Step 4

Polishing system

Although effective, this workflow increased:

• Treatment time
• Instrument costs
• Sterilisation requirements
• Inventory management

Edenta developed the S-Finisher concept to simplify the process.

The result was a highly efficient two-step finishing protocol:

Step 1

TC390S S-Finisher

Step 2

Ultra-Fine White Band Finisher

This approach significantly reduces chairside time while producing superior surface quality compared with many conventional finishing systems.

Innovative S-Finisher Technology

The TC390S belongs to Edenta’s highly regarded S-Finisher range.

The “S” designation refers to a refined blade geometry that incorporates additional spiral cross-cutting technology designed specifically for composite finishing applications. This innovative cutting design optimises:

• Cutting performance
• Surface smoothness
• Material removal efficiency
• Handling characteristics
• Clinical predictability

The geometry combines rake angle, blade depth and blade spacing to maximise cutting efficiency while simultaneously producing a remarkably smooth surface.

Why Surface Quality Matters

The quality of a composite restoration is determined not only by the material selected but also by the quality of the finished surface.

A rough restoration surface can contribute to:

• Increased plaque retention
• Surface staining
• Reduced gloss retention
• Gingival irritation
• Increased wear
• Reduced patient satisfaction

A highly refined surface offers significant advantages:

Improved Aesthetics

Smooth restorations reflect light more naturally and closely mimic enamel.

Enhanced Stain Resistance

Reduced surface irregularities minimise staining potential.

Better Gingival Health

Smooth surfaces accumulate less plaque.

Greater Longevity

Highly polished restorations generally maintain aesthetics for longer.

The TC390S helps create the foundation for these long-term benefits.

---

Flame-Shaped Design Advantages

The TC390S features a flame-shaped profile specifically chosen to provide maximum versatility in aesthetic restorative procedures.

Benefits include:

Excellent Interproximal Access

The slender profile allows access to areas that are difficult to reach with larger finishing instruments.

Improved Margin Finishing

Clinicians can refine margins accurately without removing excessive material.

Enhanced Visibility

The shape improves visual access during finishing procedures.

Greater Precision

The tapered working area provides exceptional control when refining fine details.

---

Perfect for Composite Bonding

Composite bonding procedures require meticulous finishing if restorations are to blend seamlessly with surrounding enamel.

The TC390S allows clinicians to:

• Blend restoration margins
• Refine facial contours
• Smooth composite surfaces
• Improve emergence profiles
• Create natural transitions

The result is a restoration that becomes virtually invisible to the patient.

---

Ideal for Direct Composite Veneers

Composite veneers place particularly high demands on finishing instruments.

Patients expect:

• Natural appearance
• High gloss
• Smooth surfaces
• Long-term aesthetics

The TC390S provides exceptional control when:

• Refining facial anatomy
• Blending veneer margins
• Finishing cervical areas
• Adjusting line angles
• Smoothing facial surfaces

Its flame-shaped design makes it particularly effective when working in aesthetic zones.

---

Exceptional Performance in Class III and IV Restorations

Anterior restorations often require precise contouring and margin refinement.

The TC390S excels in:

Class III Restorations

Smooth interproximal finishing and contour refinement.

Class IV Restorations

Incisal edge refinement and facial surface finishing.

Diastema Closures

Seamless blending of composite additions.

Edge Bonding Procedures

Creation of natural enamel-like transitions.

---

Reduced Finishing Time

One of the greatest advantages of the TC390S is its ability to streamline finishing procedures.

The specialised blade design enables:

• Faster contouring
• Simultaneous smoothing
• Reduced instrument changes
• Improved workflow efficiency

For busy clinicians, these time savings can have a significant impact across multiple restorative procedures.

S-Finisher

Finishing a composite filling is reduced from 3 to 2 steps using the S Finishers.

Step (1) = S Finisher, step (2) = Ultra-fine

Finisher (white ring). Highlustre polishing is then completed using the TopGloss one-step diamond grit polisher (3).
