Premolar Clamp Number 202 for Rubber Dam Isolation

Premolar Clamp Number, SKU PS-D-107, is a reusable endodontic rubber dam clamp made from German stainless steel for premolar isolation, root canal therapy, restorative dentistry, adhesive procedures, crown-margin control, and operative moisture management. The product is supplied as one rubber dam clamp and the visible marking identifies a 202 premolar clamp pattern with a curved bow, winged extensions, forceps holes, cervical gripping contours, and a central access opening for controlled isolation around premolar crowns. The clamp is used during premolar endodontic access, class I restorations, class II cavity preparation, composite placement, amalgam replacement, coronal buildup, crown preparation isolation, pediatric posterior procedures where crown size permits, and veterinary dental restorations. The winged structure supports preloading with a rubber dam sheet before placement, while the jaw design stabilizes the clamp at the cervical contour during irrigation, suction, handpiece use, matrix placement, bonding, and restorative finishing. Endodontists, general dentists, restorative clinicians, pediatric dentists, dental schools, hospital dental departments, veterinary dental teams, distributors, and procurement offices use this Class I reusable isolation instrument in rubber dam kits, endodontic trays, and operative dental setups.

202 Bow, Wing, and Jaw Mechanics

The Premolar Clamp Number uses a spring stainless steel bow to separate the jaws during forceps loading and to maintain retentive pressure after seating. The bow remains outside the operative crown surface, leaving the central field accessible for rotary preparation, pulp chamber entry, restoration placement, and coronal sealing. The 202 jaw profile is shaped for premolar retention, with cervical contact areas that engage the buccal and lingual contours of the tooth and resist displacement during irrigation, suction, and restorative manipulation. The winged extensions hold the rubber dam sheet while the operator carries the clamp and dam together to the tooth. This is useful when the clinician wants the sheet positioned with the clamp before inversion around the crown. The circular forceps holes accept rubber dam forceps beaks for opening, transfer, seating, stability testing, and removal. The clamp has no ratchet, screw joint, box lock, or pivot because its working mechanism depends on spring tension, jaw contact, winged dam support, bow resilience, and forceps-controlled placement.

Premolar Isolation During Endodontic and Restorative Procedures

During endodontic treatment, the Premolar Clamp Number is selected after clinical crown assessment, dam hole punching, floss ligature preparation, and forceps loading. The clinician opens the 202 clamp with rubber dam forceps, seats the jaws at the cervical contour, verifies stability, and then inverts the dam around the premolar before access preparation. In root canal therapy, the clamp retains the isolation field during chamber entry, canal location, irrigation, instrumentation, obturation, and temporary or definitive coronal sealing. In restorative workflows, the same clamp supports class I occlusal restorations, class II proximal preparations, adhesive composite placement, matrix adaptation, liner placement, base placement, amalgam replacement, and crown-margin refinement. The winged format is useful when the dam sheet is carried with the clamp and then inverted after placement. Pediatric use is selected when eruption level and crown size provide stable engagement. Veterinary dental teams use comparable isolation logic for restorative or endodontic procedures where moisture control and stable posterior access are required.

202 Premolar Pattern Selection and Component Function

The 202 pattern is selected for premolar isolation when the operator needs a winged clamp with a compact bow that preserves crown access. The bow provides elastic memory and maintains clamp tension during the full procedure. The jaws contact the buccal and lingual cervical regions and help resist displacement during handpiece vibration, canal irrigation, suction movement, and matrix placement. The wings support rubber dam preloading, allowing the sheet to be stretched onto the clamp before the assembly is carried to the tooth. The forceps holes provide controlled engagement with clamp forceps, reducing uncontrolled finger pressure near the jaw edges. The central opening leaves the occlusal surface, access cavity, proximal box, and restorative field available for instrumentation. Selection is based on premolar crown morphology, eruption level, cervical contour, restorative margin position, adjacent tooth contact, dam hole spacing, and planned procedure. This clamp is not selected for extraction, tissue traction, orthodontic force application, or matrix retention without rubber dam isolation.

German Stainless Steel, Sterilization, and Procurement Records

German stainless steel construction gives the Premolar Clamp Number the spring resilience required for repeated premolar isolation while maintaining bow tension, jaw alignment, wing form, and forceps-hole integrity through clinical turnover. The smooth stainless finish supports visual inspection after cleaning, including the bow curve, jaw contact areas, wing surfaces, and lateral holes where debris can collect after endodontic or restorative procedures. After use, staff remove visible rubber dam fragments, cement, composite residue, blood, saliva, and irrigant deposits, clean the clamp surfaces, rinse, dry, inspect retentive edges and spring tension, package, and steam autoclave according to facility protocol. CE marking supports international medical device procurement, ISO 13485 certification reflects regulated manufacturing controls, and FDA-compliant procurement support helps United States buyers maintain reusable dental hand instrument records. The product supports single-piece ordering, replacement planning, rubber dam kit assembly, OEM supply, return support, order tracking, and documentation for clinics, hospitals, dental schools, distributors, emergency dental units, and veterinary dental departments.
