Comparative study regarding the evaluation of facial aesthetics using the classical and computerized method

Abstract

Tempting and disturbing by its purpose to correct dental malocclusions, but also asymmetries facial expressions, to shape smiles and to improve the quality of life, orthodontics has experienced a permanent dynamics in recent decades both by improving the means of diagnosis (digitization) as well as the introduction of increasingly high-performance materials: hybrid springs, mini-implants etc. An important diagnostic element in Orthodontics is photography made from the front and profile, which is also a forensic document, on which a series of angular and linear parameters are analyzed at the beginning and end of the treatment. Orthodontic diagnostic pictures are a non-invasive method of diagnosis and are made in the natural position of the head NHP, which is a standardized, reproducible position of the head in space where the subject is looking at a distant point of the eye level. The angular and metric values on the photo or teleradiography of the face/profile are essential elements in both establishing a diagnosis and the treatment plan that will aim to achieve a balanced face and a harmonious profile. These values can be transferred to the computer, and with the help of specialized software will be analyzed and interpreted for each clinical case. This study aimed to perform a comparative analysis of four angles that define the facial profile in a group of 30 patients (15 females and 15 males) patients aged 18-24 years with Angle I class malocclusions and bone growth finished. The values were measured on the profile photograph (after tracing the anthropometric points with an eye pencil) and statistically evaluated for both sexes, and the photos were scanned and important in the DSD software so that the same angles can be evaluated digitally. Digital orthodontics tends to take up more and more space in the assessment of an orthodontic case. In orthodontic treatments, the thickness of the soft parts that can compensate for an unsightly profile of the bone relief is taken into account.
