Same great features as the 3D XR but with the ability to be cured through the matrix. The contoured sectional matrix bands create proper tooth anatomy, while the rings create the required tooth separation and band adaptation for a tight, natural contact. The clear plastic bands nearly eliminate flash. Both the CLEAR Soft-Face 3D-Ring and the 3D XR ring adapt to the contours of the tooth to nearly eliminate flash. The 3D XR ring grabs the teeth to eliminate spring-off and is ideal for small, malpositioned teeth or between canines and premolars.
