About

The aim of the present study was to compare the outcomes of incisions made by Colorado® microdissection needle, electrosurgery tip and surgical blade during periodontal surgery.

Full description

Commercially, many microdissection needle systems are available, such as Stryker Colorado® microdissection needle (CMN) (Stryker-Leibinger, Freiburg, Germany) and optimicro™ microdissection needles. Colorado® microdissection needle (CMN) combine the advantages of scalpel and electrosurgery. CMN® was introduced into clinical practice in 1997, with a wide array of applications in the field of Ophthalmology, Neurosurgery, and others.

The primary feature of the Colorado® microdissection needle is the ultra-sharp tungsten tip that delivers the wave-form from the electrosurgery generator to a very small spot. This allows the use of extremely low wattages, resulting in less tissue necrosis, precision cutting and cautery, and less post-operative pain. The instrument tip is a delicately machined, insulated tungsten diathermy needle that is compatible with any standard cautery hand piece. Tungsten, with its extremely high melting point (>3400°C) provides a heat resistant tip that maintains sharpness compared to stainless steel tips that dull rapidly.
