| Abstract | ||
| This study was conducted on 13 female patients aged from18 to 40 years, selected from the outpatient clinic of the orthodontic department at the Faculty of Dentistry, Ain Shams University. They were selected based on specific inclusion criteria. The aim of the study was to evaluate the effect of extracting upper premolars and retracting the anterior segment on soft tissue in three dimensions using the Planmeca Proface laser scanner. In our study, we wanted to evaluate the soft tissue facial changes, so we used a 3D diagnostic aid in order to prevent any errors that could occur with 2D diagnostic tools that were previously used by many researchers. After leveling and alignment, extraction was performed to the premolars to initiate retraction of the anterior segment. Three-dimensional images of the patients were acquired using the Planmeca Romexis software laser scanner Proface immediately after extraction (prior to starting retraction) and after the retraction of anterior teeth completed. These images were later used for several measurements on facial soft tissue showed clinically significant changes mainly in anteroposterior dimensions. | ||
