Root Elevators

Soar Instrumed Manfucture Root Elevators from high-quality martensitic stainless steel 420 J2, in compliance with ISO 7153-1 for metallic materials used in surgical/Dental instruments. The material composition generally includes carbon (0.15–0.40%) and chromium (12.0–14.0%) to ensure an optimal balance of hardness, strength, and corrosion resistance. All raw materials are verified through mill certificates and, where required, spectrometric analysis to confirm grade conformity prior to production.

The manufacturing process begins with hot drop forging or precision CNC machining to achieve the required shape and optimized grain structure for mechanical strength. This is followed by rough grinding and shaping to define the instrument profile according to controlled dimensional tolerances. Heat treatment is then carried out under controlled conditions, including hardening and tempering, to achieve a working-end hardness of approximately 52–56 HRC and a handle hardness of 48–52 HRC. Subsequent fine grinding ensures precise tip geometry and functional accuracy required for clinical performance.

Surface finishing is performed through mirror polishing, satin finishing, or sandblasting depending on customer requirements, with controlled surface roughness to enhance usability and cleanability. The instruments undergo passivation using nitric or citric acid solutions in accordance with ASTM A967 or ASTM A380 to improve corrosion resistance. Cleaning is carried out using ultrasonic systems followed by rinsing with deionized water and drying in a controlled environment to ensure removal of contaminants. Laser marking is applied for permanent identification, including logo, size, and batch or lot number to ensure full traceability.

Each instrument is subjected to stringent quality control procedures, including 100% visual inspection, dimensional verification, and functional testing prior to release. Root Elevators are supplied in a non-sterile condition and are designed to withstand repeated steam sterilization cycles at temperatures up to 134°C, making them fully compatible with standard hospital reprocessing methods, including enzymatic cleaning and ultrasonic washing.

Manufacturing and quality management systems comply with ISO 13485 requirements for medical devices. The instruments meet applicable regulatory frameworks, including CE marking under EU MDR 2017/745 as Class I reusable surgical instruments, and UKCA marking under UK medical device regulations. Where applicable, compliance with US FDA requirements (21 CFR Part 820) is maintained. Biocompatibility considerations are aligned with ISO 10993 standards for patient-contact materials. Labeling, packaging, and traceability systems, including batch or lot identification and, where required, Unique Device Identification (UDI), are implemented in accordance with regulatory requirements. Packaging is performed in clean conditions using protective materials such as polybags, pouches, or blister packs, ensuring product integrity during storage and transportation.
