Mandibular Forceps

 

Introduction

Within the oral and maxillofacial surgery setting, mandibular forceps are an ideal collection of surgical  instruments utilized for the extraction of lower-jaw teeth that is efficient, anatomy-focused, and secure. Through their wonderful precision, they make extraction of mandibular teeth possible by crown grasping through forceful, firm grasp with force being applied as a focus on mobilization and extraction from alveolar bone. In exodontia and in intricate surgery, mandibular forceps are an asset of dental surgeons that provides leverage as well as control.

1. Understanding the Anatomy of the Mandible

In order to approximate mandibular forceps design and use, one should be well familiar with the anatomical features of the mandible:

•Mandibular Arch: Supports lower teeth—central incisors, lateral incisors, canines, premolars, and molars.

•Alveolar Process: The bony ridge over the teeth sockets.

•Bone Density: Denser than maxillary bone, more force and leverage needed to remove.

•Mandibular Canal: Holds the inferior alveolar nerve, which must be avoided when extracting.

•Angle and Ramus: Structural features that affect direction and access in extractions.

2. Dental Forceps Types

Dental forceps are categorized according to:

•Jaw:

Maxillary Forceps

Mandibular Forceps

•Type of Tooth:

Incisor Forceps

Canine Forceps

Premolar Forceps

Molar Forceps

Root Tip Forceps

•Design:

English pattern (vertical handle)

American pattern (horizontal handle)

3. What Are Mandibular Forceps?

Mandibular forceps are specifically designed to fit on the lower jaw. They have:

•Handles: Angled for placement of hand leverage and traction.".

• Beaks: Serrated or sharp tips for acceptance of mandibular tooth structure.

• Shank Design: Curved and longer for accessing posterior areas.

• Fulcrum Mechanism: Mechanical advantage for elevation and luxation.

4. Mandibular Forceps Types

Forceps are also categorized by tooth shape and location. Some of the most widely used types are:

• Forceps No. 151:

Universal mandibular forceps.

For lower incisors, canines, and premolars.

• Forceps No. 74 (English Pattern):

Also known as "Ash forceps" or "Bird beak forceps.

For lower anterior teeth.

•Forceps No. 17:

Specifically for mandibular molars.

 

Has pointed beaks that engage the bifurcation.

•Forceps No. 23 ("Cowhorn"):

For lower molars with bifurcated roots.

Has pump handle motion to raise.

Forceps No. 222:

Reserved for deeply placed or decayed molars.

Narrow beaks for tip engagement of root.

•Forceps No. 101:

Reserved for deciduous mandibular teeth.

5. Design Philosophy and Biomechanics

Each forceps is designed specifically to be employed for a special surgical function:

•Two-Point Contact Principle:

Beaks should contact lingual and buccal sides to be secure.

•Anatomical Fit:

Curvature is same with dental arch.

•Ergonomic Handles:

To reduce fatigue and improve control.

•Beak Alignment:

Perpendicular to handle in mandibular forceps to direct vertical position of lower teeth.

6. Mandibular Tooth Extraction Technique

Successful mandibular extraction has the following steps:

•Pre-operative Assessment:

Radiograph examination.

Evaluation of tooth mobility, root morphology, and adjacent anatomy.

•Anesthesia:

Inferior alveolar nerve block.

• Positioning:

Patient's head slightly back.

Operator in front or side depending upon tooth.

• Forceps Engagement:

Beaks approximating cervical line of the tooth.

• Luxation Movements:

Buccal-lingual rocking for anterior teeth.

Rotational force for single-rooted teeth.

Pump-handle action for molars with forceps No. 23.

• Delivery:

Controlled extraction by traction when mobility is acquired.

7. Mandibular Forceps in Pediatric Dentistry

Pediatric oral surgery:

• Forceps No. 101 or 151S are used.

• Fine usage and small-hand constructed.

• Short beaks and handles for receiving smaller teeth.

8. Surgical Complications and Forceps Design Role

Most frequently occurring complications are:

• Root Fracture: Prevented by proper beak design.

• Alveolar Fracture: Prevented by anatomically selected forceps.

• Soft Tissue Injury: Prevented by rounded surfaces and controlled sliding.

• Displacement of tooth into soft tissue: Improper or inadequate grip and/or improper selection of forceps heightens the risk.

9. Sterilization and Maintenance

The mandibular forceps will have to be

• Autoclaved between patients.

• Inspected for rust, loose articulations or wear.

• Lubricated in the hinges so that they move freely.

• Stored in padded, dry trays to avoid damage.

10. Mandibular Forceps Design Improvements

Emerging technology advancements are:

• Enhanced Serrated Grip for enhanced tactile sensitivity.

• Titanium Coated Instruments to resist corrosion.

• Laser Etched Calibration Sets to assist identification.

• Color-Coded Sets of forceps to distinguish.

• 3D Printed Prototype Models for individualized patient use.

11. Training and Expertise

Students are instructed by dental schools in:

• Recognition of varieties of forces.

• Application techniques on models and patients.

• Regulation of forces to prevent overuse or injury.

• Examination after the operation of socket integrity.

12. Use with Elevators and Other Tools

Mandibular forceps are used with:

• Periosteal Elevators: To reflect gingiva.

• Luxators: To loosen periodontal ligament.

• Bone Files or Rongeurs: In case of alveoloplasty.

• Suction Tips: To maintain field dry.

13. Mandibular vs. Maxillary Forceps Differences

• Mandibular Beaks: Parallel to handle.

• Handle Length: More length for deep access.

• Force Application: Requires more torque.

• Operator Positioning: More vertical access for lower arch.

14. Case-Based Usage Examples

• Impacted 3rd Molar Extraction:

Uses No. 222 or surgical forceps.

Combined with bone guttering.

• Anterior Fractured Root Removal:

No. 74 forceps with careful beak adaptation.

• Pediatric Extraction of Deciduous Premolars:

 101 forceps with careful luxation.

15. Common Mistakes in Mandibular Forceps Use

• Forcing Beaks: Fractures enamel or root.

• Inappropriate Choice of Forceps: Makes the procedure more challenging.

• Two-Point Contact Failure: Causes slippage.

• Failure to Obtain Preoperative X-rays: Places at risk anatomical injury.

Conclusion

Mandibular forceps are not just a surgical instrument —beware, they are the intersection of surgical science and anatomical delicacy. Used in the dental tissues with correct technique, they can provide successful, atraumatic removals of teeth. From ancient No. 151 to Cowhorn No. 23 for a special indication, they all belong to the dentist-surgeon's arsenal. The ability to manipulate these forceps is not so much a reflection of surgical skill as evidence of the dedication of the dentist to the well-being of patients.
