Nitinol file is a high-strength, wear-resistant dental instrument material with good elasticity and corrosion resistance.
Its service life depends on several factors, such as frequency of use, use technology, use environment, etc.
Generally speaking, properly used and maintained Nitinol files can be used multiple times, usually around 10 to 20 times.
The service life of Nitinol files is affected by:
1. Frequency of use: Frequent use will accelerate the wear of the file and reduce its service life.
2. Usage techniques: Correct usage techniques can reduce damage to the file and extend its service life.
3. Usage environment: Environmental factors such as temperature and humidity when using the dental machine will also affect the life of Nitinol files.
In addition, regular cleaning and disinfection of Nitinol files and timely replacement of severely worn files are also important measures to extend the service life.
In summary, properly used and maintained nickel titanium files can be used many times, but the exact number of uses will be affected by several factors.
In order to ensure the effectiveness and safety of dental treatment, it is recommended to check and replace Nitinol files regularly to ensure their good working condition.
