Study Notes

Multifunctional Application of Forceps

Beginners may struggle with forceps due to the need for balance among squeezing, twisting, and levering forces during dental extractions.

Forceps Components

Handles: Long, textured for grip; allows maximum strength transfer to the blades.
Hinge: Mechanical joint permitting opening and closing; must be maintained to prevent loosening.
Blades: Most critical component; designed to wrap around tooth root surfaces and can vary in angulation.

Grip Techniques for Forceps

Upper Teeth

Forceps are held with palm facing up (underhand grip); index finger and thumb control handles, while remaining fingers provide support.

Lower Teeth

Forceps are held with palm facing down (overhand grip); thumb and index finger control handles with proper support from other fingers.

Maxillary Forceps

Upper Straight Forceps: Long blades for incisors; shorter blades for greater grip on canines.
Upper Premolar Forceps: Slightly S-shaped; designed with wider blades and ergonomic handles for better grip.
Upper Molar Forceps: Specially designed blades for palatal and buccal roots; come in left and right pairs.

Root Forceps for Maxilla

Designed narrower for extracting upper roots due to less dense maxillary bone.
Features: Typically straight or curved handles, angled narrow blades for better access into periodontal spaces.

Maxillary vs. Mandibular Primary Forceps

Handle Design: Maxillary handles curve upward; mandibular handles curve downward.
Blade Shape: Maxillary blades angled upward, while mandibular blades are straight.
Application Focus: Maxillary designed for less dense bone, mandibular for denser structures.

Mandibular Forceps

Lower Anterior Forceps

Straight handles for vertical and lateral force application; tapered, serrated blades for precise gripping.

Lower Premolar Forceps

Designed with straight handles and slightly curved blades; enable effective access and application of bucco-lingual forces.

Lower Root Forceps

Employ bucco-lingual movements and vertical extraction techniques with long, narrow blades for deep root access.

Modified Forceps for Lower Molar

Utilize first-class lever mechanics, acting more as elevators than traditional forceps; no gripping required.
Indications include decayed, endodontically treated, or fractured teeth, as well as challenging root configurations.

General Design Considerations

Long, narrow blades and serrated surfaces enhance gripping ability, particularly for root fragments.
Precision in design allows efficient access and control during dental extractions.
