Crown & Shell Plier 13cm

Crown & Shell Plier 13cm

The Crown & Shell Plier 13cm measures 130mm in total length and is forged from medical-grade stainless steel with a high-polish finish. The jaw assembly carries two identical wide, flat beaks, each face machined with a deep rectangular U-shaped notch that creates two parallel prongs per beak face. This fork profile is clearly shown in the jaw close-up thumbnail in the product image. The U-notch straddles the crown wall during each compression stroke, gripping the stainless-steel crown shell at the gingival third without slipping off the margin edge. Both beak faces are smooth with no serrations, allowing the prongs to slide along the crown wall during the overlapping “walking” crimp sequence without scoring the metal surface.

The instrument operates on stainless steel crown shells measuring 0.18mm to 0.22mm in wall thickness. The box-joint hinge maintains beak parallelism under repeated compression cycles. The spring-action handle separates the jaws between each working stroke, allowing the operator to reposition around the crown circumference without removing the instrument from the oral field. The instrument is fully autoclavable at 134°C.

Pediatric dentists use the Crown & Shell Plier 13cm during stainless steel crown placement on primary molars, specifically in the final crimping stage, where the gingival margin is compressed 1mm inward circumferentially to conform to the cementoenamel junction. contouring Pliers shape the crown body first; this instrument then completes the marginal adaptation step that determines gingival seal and crown retention.

Leader Surgical produces this instrument with verified U-notch width tolerances matched to standard stainless steel crown wall thickness ranges, ensuring consistent crimping depth across the full Crown Pliers range used in pediatric restorative procedures.
