Piezo-electric surgery is a procedure used recently in Oral-Maxillo-Facial Surgery . The basic mechanisms are ultrasounds, that working in a frequency range between 25 and 30 Khz, determining very low oscillations on the tip of the handpiece, with effectiveness in cutting hard tissue but absolutely atraumatic on the soft tissue , with bio-stimulating effects. Piezo-electric cut takes place thanks to a modulate ultrasonic micro-vibration of 60-200 micro-meters of wideness, that it is able to cut all the mineralized tissues with the utmost respect to the soft tissue, impossible to damage even in an accidental contact. The bio-stimulation induces neo-angiogenesis, proliferation of epithelial tissue, increase of osteoblastic activity. In our Department of Maxillo-Facial Surgery a clinical study is ongoing whose aim is to demonstrate Piezo-Surgery validity as an adjuvant treatment for patient management in stage I (a,b), II (a,b) and stage IIIa (following the AAOMFS classification).
Materials and methods
From January 2003 to September 2009, 18 patients were treated with ONJ, 11 male and 7 female, range of age between 55 and 75. 16 of them have been cured with Zolendronic acid for cancer and 2 with Alendronic acid for osteoporosis. All the patients’ clinical conditions were classified following the AAOMFS.
Amoxillina 1gr cp : 2 cp/die per 10 gg.
Clorexidina coll. 0,2%: rinses three times/day for 10 gg.
Nistatina 2-3 mis.die per 10 gg.
Metronidazolo cp 250 mg 2 cp per 4 die in 1 gg
Each cycle of therapy between the other has ten days of drug holiday
PiezoSurgery carried out a clinical improvement of patients for its biostimulation effects.
