The problem of dental burs failure on high-speed handpiece
Problem: Bur locks in the chuck，can't removed
Possible Cause:
①Debris buildup in the chucking mechanism.
②Use of non-ISO compliant burs.
③The deformation and bending of the bur damaged the chuck.
④Push button can not used.
Solution:
①Clean spindle with High-Speed lubricant oil spray.
②Always use ISO burs less than 24 mm in overall length and with a shank length of at least 7.3 mm.
Problem: Spindle clamping force is weak
Possible Cause:
①The initial clamping force of the spindle is too low.
②Spindle chuck is worn lead to reduced the clamping force.
③Poor maintenance, debris stuck chuck.
④The bur size is not standardized and small.
Solution: Clean and maintain the spindle regularly; use standard burs.
Problem: The bur cannot be inserted spindle
Possible Cause:
①The bur is too big
②There are too many burrs inside the spindle
Problem: Bur slips in the chuck

Solution: Remove bur from spinle per the manufacturer’s instructions and re-install correctly.
Problem: The reason why the surgical burs is easy to break?
Possible Cause:
①The burs quality is bad.
②The high speed handpiece cooling system is not good, the heat produced by the high-speed rotation of the bur is not effectively cooled.
③Improper operation by the dentist. Applying excessive pressure to the bur could cause unwanted heat and bur failure. In fact, applying pressure to the bur is very often a sign that the bur needs to be replaced. Damaged burs may damage the handpiece and cause pain to the patient.
Solution: Choose a three-hole water spray hand-piece, which water can accurately spray the needle. And with a good bur.
Problem: What are the advantages and disadvantages of tungsten steel burs?
Advantages: sharp and strong cutting force
Disadvantages: fragile and easy to break
Problem: What is the length of surgical burs？
Size: 25mm 26mm 27mm 28mm 32mm
SENDA 45 Degree Surgical Handpiece suitable for length of 25mm and 26mm length of burs. Three hole water spray can spray the bur accurately.
A well-selected bur not only has a large cutting force, less vibration, and higher work efficiency, but also can maintain the life of the bearing and make the patient experience better.
