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
The Sapphire SL brackets are designed for wires form .012 round up to
.017 x .025 for the .018 slot and up to .021 x .025 rectangular for the
.022 slot. All wire materials are possible. The Sapphire SL will be available in
MBT and Roth, no Hooks or Hooks on 3,4,5.
