Over
a quarter of century of service to the orthodontists
Sooner or later, you
will reuse the so called "single use only" orthodontic appliances: "No army can overcome an idea whose time has
come" (Victor Hugo)
- The brackets we clean are:
- "Safe and effective", Dr.
D. Poulton, A.A.O. President (1998)
"Substantially equivalent [to new ones]", F.D.A. (1991)
"Not dimensionally different", M.W.Haller, Forensic expert (1998)
"Not clinically different", Ontario Dental Association (1994)
"Not altered mechanically", D.L.Buchman (AJO 1980)
"Economic, achieving the same performance", G.Buchwald (AJO 1989)
"Can be incorporated in orthodontic offices", D.E.Machen, DDS,
Attorney,Judge and AJO Consultant (AJO 1993)
Safer than new:
"The maximum release of
nickel in new brackets reaches a maximum in the first week, after which it declines" (Barret
RD, Bishara SE, Quinn JK, Am J Orthod Dentofac Orthop 1993; 103: 8-14).
"The cumulative amounts of nickel and chromium released reaches a plateau after 6
days" (Park HY, Shearer TL, In vitro release of nickel and chromium from
simulated orthodontic appliances, Am J Orthod Dentofac Orthop 1983; 84: 156-9) |
