Innovative Material
The Sapphire SL is manufactured out of the very innovative and new
Premium
Material which is the next generation beyond polycristalline
alumina. It is
clear and doesn‘t stain anymore like the common polyurethane and
poly-
carbonate materials and doesn‘t abrade like ceramic.
The material of the Sapphire SL is hard enough not to deform during
treatment
like standard composite brackets tend to do. It is very abrasion
resistant
but its shore hardness prevents the teeth from being damaged like
it might
happen by strong for-bites with ceramic brackets. Furthermore the
strength
ensures no fractures of the bracket during the removal process.
Premium material is a despersion of different kinds of medical
grade and
highly biocompatible copolymers with a small portion of ceramic to
increase
strength and hardness. It is approved by biocompatible tests like
mutagen,
skin sensitization, cytotoxicity and oral toxicity and has beek
certifi ed accor-
ding the MDD. Analysis also showed no leakage of PBA.
Friction Forces
Due to the new material composition the brackets show outstanding
ultra-
low frictional forces for premium sliding mechanics compared to all
other
used bracket materials of the market. This allows full control of
the treatment
forces.
Mechanical Locking Base
The bracket also features a mechanical locking fi shgrate base.
This means
that the glue is pushed away from the gingiva and therefore very
easy to
remove. There is no need of any additional coating or silane. The special
base provides excellent shear forces and easy debonding.
Prescriptions
