Diode laser overview: how it is done and how to manage it
Flat wave handpiece Designed by Prof. Alberico Benedicenti of the University of Genoa, father of laser therapy in the cranio-cervicofacial field, the flat wave handpiece (! 2.31) is a device capable of emitting a quantity of energy constantly distributed over a surface of 1 cm2, maintaining the same fluences up to a distance of about 100 cm from the area involved in the treatment.16 The handpiece uses a special system of lenses, which allow a constant focus of the laser beam, thus allowing to deliver the

same energy density thanks to the constant focusing system. The resulting laser beam emission will therefore be flat and not conical, ensuring a more effective and uniform penetration into the tissues and a better result in therapies, completely eliminating possible operator errors.17 The uniform distribution of energy, made independent of the distance of application, makes it possible to make the biostimulation and photobiomodulation procedures predictable, repeatable and not operator-dependent (! 2.32-2.35).

! 2.28 Placement of a quick connection tip with integrated optical fiber. A locking ring ensures the tip in its correct position.
! 2.29 Handpiece defocused by biostimulation. The spacer tip can be separated and disassembled from the base and sterilized.
! 2.30 Unfocused laser beam.
