Overview
ISO 17937:2015 - Dentistry - Osteotome is the international standard that specifies design, material, dimensional, performance and labelling requirements for dental osteotomes used for bone compaction, internal sinus floor elevation (sinus lift) and jaw bone cleaving during implant site preparation. Published by ISO in 2015, it sets test methods and acceptance criteria to ensure safety, durability and traceability of handheld dental osteotomes.
Key Topics and Requirements
- Scope & classification
- Covers Type 1 (sinutome), Type 2 (condenser) and Type 3 (chisel); shank forms: Form A (straight) and Form B (offset).
- Dimensions and tolerances
- Working-end diameters must be within ±0.1 mm of manufacturer’s stated size.
- Overall length (handle + working end) shall not exceed 175 mm.
- Shapes and working tips
- Specifies preferred working-tip geometries (cylindrical sinutome, conical condenser, pointed or angled chisel) and detailed profiles for clinical function.
- Materials
- Materials for working ends and handles are required to conform to ISO 13504 (materials for dental implant instruments).
- Marking and labelling
- Depth scale marking in 2 mm steps; markings must be readable without magnification and at least the 8–16 mm region must be marked.
- Mechanical and surface requirements
- Surface must be free of visible defects (visual inspection).
- Hardness requirement: ≥480 HV1 or ≥48 HRC (tested per ISO 6507-1 or ISO 6508-1).
- Reprocessing resistance
- Devices must withstand 100 reprocessing cycles (manufacturer’s cleaning, disinfection, sterilization) without visible deterioration; hardness and connections must still meet requirements after reprocessing.
- Connection strength
- Shank-to-handle assembly must resist:
- Tensile force: 1 000 N for 5 seconds.
- Torque: 500 N·cm for 5 seconds.
- Impact surfaces must withstand hammering forces.
Applications and Users
ISO 17937:2015 is used by:
- Dental implant manufacturers and instrument designers to develop compliant osteotomes.
- Quality, regulatory and compliance teams preparing technical files and CE/market submissions.
- Dental clinics, oral and maxillofacial surgeons, and prosthodontists selecting instruments for sinus lifts, bone compaction and osteotomy procedures.
- Sterilization/central processing departments to validate reprocessing protocols and instrument longevity.
Practical benefits include improved patient safety, predictable instrument performance, clear depth control (marking), and standardized testable criteria for durability and material hardness.
