I am surprised nobody considereed it important enough to discuss the frequencies ofthe various machines on offer and choose relative to the merits that the various machines have as theri specs rather than go by one or the other's "experience".
Look for the Frequencies at which bone cutting is facilitated in all these machines. Look and read between the lines as some of them will have specs that read ... " Min Cutting frequency .. " and "Range of cutting frequency"
As the philosophy of the Ultrasonic bone ssurgery devices are all based on the fact that only at optimal frequencies does bone cutting happen with cell death occusring from Cell"Implosion" or "Cavitation" as opposed to the conventional cell death by cell "Explosion" from Inreased Itracellular pressure and oedema, seen in conventional bone cutting techniques such as burs, saws, chisels etc.
The range that Tomaso Vercelloti has set for his machine (the second generation Mectron Piezosurgery) is 22 to 28KHz. He bein the pioneer in the field of Piezosurgery, and the one who apparently discovered this facet of bone surgery, would make sense to go buy the machine inspite of the so called costs nvolved.
I did that almost 3 years ago. Have broken a few tips in the first year of use. But then, as an Oral and Maxillofacial Surgeon, I tried it on the Tibial regularly for harvesting Tibial bone,on the iliac crest. Have documented cases of Rhinoplasty for access to the anterior skull base, Maxillectomy etc.
There is a learning curve to it and is soon mastered (I believe if I can , anyone can!).
In the last 16 months I haven't broken a single tip. Just used the Piezo on 2 patients in the last 2 days at a workshop at Safdarjung hosp in Delhi . A rige split , and a Sinus Lift with Autogenous block bones harvested off the symphysis . Did a large span Maxillary Ridge Split for Expansion last month along with a colleage who's a friend (Dr Maanav Nayyar) at his clinic in West Delhi, demonstrated a Block bone grafting and a Maxillary Split and Expansion 2 months ago at the COD SUrgery at Manipal, a case at Kochi etc....
Have had no breakages, no tips heating...blah blah..
Have no reason to crib about other systems. Have tried UBS , EMS, and Osada during the aAdvanced Implanmtlogy courses that I was faculty at, with a close friend and Implantologist. I guess he shares my opinion that the Piezo Osada EMS and Satelec came out 2nd best and Mectron was a winner, hands down in terms of cutting effieciency.
After sales service is the biggest let down though, at least in our part of the world.
By the way, I do not have any commercial interests with Mectron, nor do I lecture or contribute to their sales diretly or indirectly.
