Aim: To create a precise tooth preparation guide tray for attachment placement during the orthodontic clear aligner treatment. Background: The primary issue clinicians encounter with the clear aligners is precisely etching the future area of attachments on the teeth, which when arbitrarily done might lead to excess flash when placing the attachments. Technique: Here we present a Modified Attachment Template (MAT) tray created by sectioning the attachment bubble from the custom attachment tray to precisely etch the future area of attachments. This MAT tray will help us in resolving the problem of composite flash removal. Clinical Significance: By precisely etching the future attachment areas we can reduce the patient discomfort and avoid the added chair-side time involved while removing excess flash using burs.
