Rubber Dam Forceps (Ivory Forceps): Precision, Isolation, and Operative Mastery in Dentistry.

Rubber Dam Forceps (Ivory Forceps): Precision, Isolation, and Operative Mastery in Dentistry.

Introduction

Isolation of the teeth is essential for effective restorative and endodontic therapy. It provides a clean, dry, and uncontaminated field to work in. Of all the instruments that make this critical control possible, the Rubber Dam System stands paramount. In this system, the Rubber Dam Forceps, and particularly the Ivory Forceps, are essential instruments.

Whereas the rubber dam itself isolates saliva, bacteria, and moisture from reaching the field of treatment, the clamps need to be properly seated on teeth in order to support the dam in place. The Ivory Rubber Dam Forceps are precisely made to accomplish the task, allowing clinicians to seat and remove clamps with control, precision, and safety.

Overview of Rubber Dam Isolation

It is crucial to know the importance of rubber dam isolation before venturing into the Ivory Forceps.

Purpose of Rubber Dam Use:

Offers a dry and clean operative environment.

Avoids saliva contamination during endodontic and restorative treatments.

Prevents the patient's airway from being contaminated by instruments and materials.

Permits better visibility and access by retracting soft tissues.

Promotes patient protection and operator effectiveness.

Rubber dam isolation consists of multiple components: the dam sheet, frame, clamps, punch, and forceps. Each is assigned a specific purpose—but it is the forceps that allow safe placement of the clamps.

What Are Ivory Rubber Dam Forceps?

The Ivory Forceps are rubber dam clamp placement forceps that serve to expand and transfer clamps across a tooth and hold them in place at the cervical region. They are defined by precision grip mechanisms, curved arms, and a locking spring that keeps the clamp in place as it is being manipulated.

Invented initially by Dr. Ivory, these forceps were among the earliest standardized instruments for rubber dam clamp placement and have not undergone much change because of their efficient and ergonomic design.

Components and Design Features

Ivory Forceps are mechanically simple but carefully designed.

Major Parts:

Handles: Two arms that the clinician holds to regulate clamp tension.

Jaws: Angled and grooved for secure engagement of clamp holes.

Hinge Joint: Permits expansion and controlled movement.

Locking Spring or Joint: Holds jaws in open or closed states.

Pivot Point: Directs pressure applied on handles to the jaws.

Design Characteristics:

Made of high-grade stainless steel for durability and sterilization.

Grooved or cupped jaw ends for clamping on different clamp hole sizes.

Sometimes 12–15 cm in length for best hand control.

Mildly angled shanks to reach posterior and anterior teeth without hindering vision.

Functional Role in Clinical Dentistry

Ivory Forceps are essential for proper and safe rubber dam clamp placement.

Primary Functions:

Transporting clamps from the tray to the tooth.

Expanding clamps for controlled placement.

Retracting clamps during removal of rubber dam.

Securing clamps while seating the dam over teeth.

Replacing or repositioning clamps in multi-step procedures.

Indications Across Specialties

Although usually linked to endodontics, Ivory Forceps are applied across specialties in dentistry.

Endodontics:

Averts canal contamination by isolating the tooth during obturation and pulp therapy.

Improves visibility when accessing root canals.

Operative Dentistry:

Provides a dry field for bonding of composite restorations.

Enhances bonding by removing moisture at margins.

Pediatric Dentistry:

Avoids aspiration or swallowing of small instruments during primary tooth treatments.

Prosthodontics:

Applied during core buildups and post placements for dry bonding conditions.

Types of Ivory Forceps

While the majority of forceps follow the traditional Ivory design, there are exceptions to suit preferences in procedures and anatomical issues.

Common Types:

Standard Ivory Forceps – For general dental isolation.

Ivory-12A Forceps – With jaws a little longer for use on molars.

Ivory-style Posterior Forceps – Increased angle to accommodate second and third molars.

Mini Ivory Forceps – To accommodate pediatric patients or restricted mouths.

Design Differences:

Jaw curvature: Straight or curved for anterior or posterior.

Handle shape: Finger-rest extensions, textured handles, or ergonomic design.

Spring tension: Altered to provide greater or lesser clamp engagement.

Clinical Technique and Instrument Handling

Achieving mastery of the Ivory Forceps involves coordination, mechanics, and skill.

Step-by-Step Technique:

Choose proper clamp and attach to forceps through holes.

Press forceps together to open the clamp.

Direct clamp over the target tooth.

Seat clamp at or below the height of contour at the cervical third.

Release pressure slowly, with stable placement.

Verify stability of clamp using explorer or finger.

Advantages of Ivory Rubber Dam Forceps

These instruments provide numerous clinical benefits that lead to procedural success.

Clinical Benefits:

Firm grip reduces clamp slippage on placement.

Angled shape provides access to hard-to-reach posterior teeth.

Controlled expansion avoids overextension and breakage.

Universal applicability to different sizes and shapes of clamps.

Durable and autoclavable, allowing long-term use.

Ergonomics and Operator Efficiency

Repeated rubber dam placement in a day can cause fatigue; therefore, ergonomic forceps are necessary.

Ergonomic Features:

Textured handles for grip, even when gloves are used.

Balanced weight distribution to minimize wrist fatigue.

Locking spring mechanisms for regulated jaw release.

Finger-stabilization ridges for better precision.

Newer models are made to decrease muscle fatigue and improve placement speed, especially for long procedures.

Sterilization and Care of Instruments

Ivory Forceps are disposable and must be given careful maintenance for their long lifespan.

Cleaning and Sterilization Procedure:

Rinse under running water to clear blood, debris, or cement.

Use enzymatic detergent soak if necessary.

Soak in ultrasonic cleaner for extensive cleaning.

Steam sterilizes (121°C to 134°C).

Lubricate hinge joint from time to time with medical-grade oil.

Regularly inspect for corrosion, wear, or spring fatigue.

Pediatric Applications and Modifications

The use of rubber dam is more and more highlighted in pediatric treatment for its safety and procedural control.

Pediatric Modifications:

Small frame size for accommodating children's face proportions.

Small clamps and associated forceps.

Low-tension forceps that allow room for softer primary enamel.

Limitations and Clinical Considerations

Though highly effective, Ivory Forceps are not without issues.

Limitations:

tough to manage in patients with a reduced opening.

mis-angulation can result in soft tissue trauma.

forceps over-compression deforms clamps.

have learning curve for effective, single-handed operation.

Comparison with Other Rubber Dam Instruments

Though Ivory Forceps are still favored, substitutes are available.

Comparison Factors:

Ivory vs. Brewer Forceps – Brewer types are heavier but can provide stronger spring tension.

Ainsworth vs. Winged Placement Systems – Ainsworth more flexible and vertical clamp placement possible but less standard.

Ivory vs. Ainsworth Forceps – Ainsworth more flexible but less frequently utilized.

Ivory vs. Winged Placement Systems – Ivory generally used for clamp-first technique; winged systems typically used for dam-first placement.

Developments in Contemporary Forceps Design

Instrument design has developed to provide greater precision and convenience.

Innovations:

Color-coded handles to identify size.

Non-stick jaw coatings to minimize clamp slippage.

Spring-loaded locking mechanisms for improved control.

Titanium alloy choices for lightweight strength.

Advanced models with adjustable tension settings.

Integration with Digital Dentistry and Training

Placement of rubber dam is still an essential step in digital processes such as CAD/CAM dentistry.

Integration Areas:

Utilized when making digital impressions to isolate prep margins.

Guarantees saliva-free field for intraoral scanning.

Featured in dental simulation labs used to train students.

Tutorials frequently employ Ivory Forceps to teach the isolation protocol.
