Overview
ISO 16635-2:2014, published by the International Organization for Standardization (ISO), specifies key requirements and test methods for clamp forceps used in dental rubber dam procedures. Clamp forceps are essential dental instruments designed for the precise application of dental rubber dam clamps during restorative dental treatments. This standard ensures dental professionals use safe, reliable, and effective forceps that meet strict quality criteria, promoting best practices in dental isolation and patient care.
Key Topics
-
Scope and Purpose:
The standard defines the criteria for clamp forceps intended to place dental rubber dam clamps accurately and securely on teeth, supporting effective dental isolation techniques.
-
Instrument Design:
- The clamp forceps should be crafted to avoid contact with the teeth during application.
- The working end must include angled or stepped retaining pins with a controlled insertion depth, enabling safe use and proper clamp orientation.
- Locking mechanisms are required to secure clamps both during and after placement.
-
Material and Surface Requirements:
- Forceps must be made from corrosion-resistant stainless steel, ensuring durability and resistance to repeated sterilization.
- Surface finishes-either brightened or matted-must be free of pores, cracks, or residues.
-
Dimensional and Mechanical Criteria:
- Maximum total length must be ≤ 175 mm and handle distances in the closed state ≤ 95 mm.
- Retaining pins and clamp receiver dimensions are specified for safe and effective performance.
- Spring mechanisms must return the forceps to their original closed state automatically.
-
Quality and Durability Testing:
- Visual inspections and precise measurement methods are mandated.
- Forceps must withstand at least 100 sterilization cycles with no signs of corrosion or functional deterioration.
-
Marking and Traceability:
- Each forceps must be marked with manufacturer or brand name, model/reference number, and batch/lot number for traceability.
Applications
ISO 16635-2:2014 is critical for:
-
Dental Device Manufacturers:
Ensuring that clamp forceps meet international standards for safety, performance, sterilization resistance, and traceability. Adherence supports certification, regulatory compliance, and global acceptance.
-
Dental Professionals:
Providing assurance that instruments are fit for use in precise dental procedures, minimizing risk to patients and enhancing treatment isolation with dental rubber dam systems.
-
Procurement and Quality Control:
Serving as a reference for purchasing departments to select compliant dental forceps, and for quality assurance teams to verify conformance during inspections and audits.
-
Training and Education:
Supporting curriculum development for dental education regarding proper instrument selection and standard-based procedure implementation.
