Esthetic Provisional Restoration after Space Closure in Patients with Missing Upper Lateral Incisors
Volume 50 : Number 6 : Page 0 : Jun 2016
Orthodontic space closure in a patient with a missing upper lateral incisor requires a mesial shift that will bring the canine and first premolar into esthetic focus. Additive or subtractive restorative measures such as odontoplasty or enamel reduction will then be needed to alter the visible tooth surfaces. Many cases require individualized adaptation of tooth shapes and colors.

Etching Mask for Invisalign Attachments
Volume 54 : Number 3 : Page 173 : Mar 2020
A duplicate attachment template tray is ordered from Align Technology and then modified with a scalpel to remove the composite wells. The modified tray is used as a mask to control etchant placement and thus limit the amount of flash, simplifying the bonding appointment.
