Intermediate burs are only used when the cortical bone is particularly resistant (in the lower arch) and make it possible to obtain a first expansion at cortical level that is perfectly regular and central to the pilot hole.

The final burs allow a gradual expansion of the hole from the inside to minimise surgical trauma and with less heating of the bone tissue.
Finishing burs make it possible to obtain a hole that almost matches the size of the implant, which can acquire its primary stability by self-tapping, due to the elasticity of the bone tissue.
Intermediate thread cutters are always used after the final bur and therefore replace finishing burs when bone quality is unfavourable, with frail cancellous bone and thin cortical bone.
The support is fitted onto thread-cutters and implant inserters so that they can be tightened manually. The support also makes it possible to use the automatic wrench to tighten thread-cutters and inserters.
The locking screw makes it possible to adjust the length of thread-cutters and inserters to suit the interocclusal distances present.
The cylindrical gauges are inserted into the drilled hole and used to check the length of the implant to be inserted and the conformation of the bone margin, on the basis of which it may be necessary to trim the implant margin to suit the conformation of the bone tissue.
Tungsten carbide cutter
The tungsten carbide bur is used to quickly cut the top edge of the implants before insertion in order to adapt them to the bone crest.
The drill is used without spray with intermittent cooling of the physiological solution of the myocromotor for implantology.
Inserters are internal screwdrivers that adapt to the eccentric bore of the implants and allow direct manual tightening or use of the automatic wrench. The support is fitted onto the inserter and locked at the desired height, according to the interocclusal distance present.
