What are the classification of dental files?
With the rapid development of dental microscopy technology and materials science, root canal treatment instruments are gradually moving towards refinement and intelligence. As a core tool, the classification and performance of dental root canal files directly affect the effect of root canal remodeling and the prognosis of patients.
Dental root canal file is a tool used for cutting, leveling, cleaning and shaping tooth bone and root canal in dental treatment. It can effectively remove diseased tissue, bacteria and other dirt from the root canal, establish root canal formation and drain the cut tooth residue for root canal treatment.
The root canal file is usually made of stainless steel or Nickel-titanium.
Stainless Steel Files
Feature: Traditional process, high rigidity, usually suitable for straight root pipes.
Nickel-titanium Files
Feature: High elasticity, strong fatigue resistance, and is usually suitable for curved root canals.
Besides this, Dental Files divided into hand files and engine use files, and different types of file have their own application scenarios, which need to be selected according to root canal morphology and treatment needs. Hand root canal files
Application scenario:
Complex root canal dissection
Root canal retreatment
Teaching and training
Features:
Hand use operation, strong tactile feedback.
Mostly stainless steel materials, cost-effective.
Easy to use, flexible operation.
Application scenario:
Efficient root canal preparation
Extensive dental tissue removal
Features:
Machine-assisted, rapid root canal treatment. Standardized operation, high cutting efficiency.
Mostly nickel titanium material, good flexibility.
