popularity recently. Onaverage, dental laboratorieshave
beenworkingwith them for 6or 7years.
Whatare someof themostcommon systems
and softwareusedby labs?
Labs canworkwithvirtuallyany systemasdigital
impressions systemsnowhaveopenarchitecture.
Initially, CEREC® scans (fromSirona) couldonlybe
received throughCERECConnect andviewedor used
bySirona’sCAD/CAM software. Sironanowoffers the
option topurchasea licenseallowing labs toconvert the
original CERECfiles intoanSTLfile, so theycanbeused
withanyCAD/CAMplatform.
Cadent iTero®digital scans arepopular. Theadvantage
of the iTero system is thequalityof themilledmodels
that areproduced indedicatedmillingcentres suchas
Core3dcentres®. Iteroalsoowns a large shareof thedigi-
tal impressionmarket due to its acquisitionby Invisalign®
(AlignTechnology) andas such, orthodontists arenow
able to send scans insteadof conventionalmodels to
Invisalign for the fabricationof sequential trays.
