| Objective:With the development of orthodontic technology and the growing orthodontic demand of people,the health and beauty ofstomatognathic system has drew more and more attention. So far, orthodontic treatment has become one of the most important ways to improve facial beauty. However, people’ sfacial aesthetic perception is usually verysubjective,which is affected by many factors such as region, gender, age, education, characteristics and living environment. So to grasp the preference to facial beauty of orthodontic patients is very important in the treatment planning. Therefore, this investigation is aimed toinvestigate the difference of orthodontic patients’ facial aesthetic perception and the facial aesthetic perception changes of patients who received orthodontic treatment, in order to instruct orthodontic treatment to improve satisfaction.Methods:Part1:A panel of213orthodontic patients who have not received orthodontic treatment from Shandong University Stomatology Hospital evaluated the facial beauty of sets of four standardized photographs (one frontal, one frontal smiling, one lateral and one frontal occlusal) of45patients (class â… 15,class â…¡15,class â…¢15). Results were statistically analyzed.Part2:A panel of100orthodontic patients from Shandong University Stomatology Hospital evaluated sets of four post-treatment standardized photographs (one frontal, one frontal smiling, one lateral and one frontal occlusal) of30orthodontic patients (class â… 10,class â…¡10,class â…¢10), in relation to the pre-treatment sets of the same patient, on a five-point scale before their orthodontic treatment and after one year and a half. Results were statistically analyzed.Results:The first part of the research shows that:â‘ Class â…¢ is considered to be the worst beauty for orthodontic patients, followed by class Ⅱ’, then class â…¡2and class â… patients.â‘¡Sex, age and education rather than marriage condition are factors affecting patients’ facial aesthetic perception. The facial aesthetic perception of adult women with a higher level of education is better than young male patients with a lower level of education.The second part of the research shows that:â‘ Patients saw an aesthetic improvement following orthodontic treatmentin Class â… , Class â…¡ division1, and Class â…¡ division2patients. This aesthetic improvement was significant. But there is no aesthetic improvement in Class â…¢.â‘¡The facial aesthetic perception of patients who received orthodontic treatment improved significantly. Among the patients, the facial aesthetic perception of the middle-aged female patients with a higher level of education improved most significantly while the lower-educated young male patients’ facial aesthetic perception did not improve significantly. Both extraction and non-extraction patients’ facial aesthetic perception have improved, but there was no significant difference.Conclusions:1. The facial aesthetic perception of adult women with a higher level of education was better than young male patients with a lower level of education. Therefore the former is much stricter to the orthodontic outcome. We orthodontic doctors should pay more attention to them and know their preference for beauty to make an individual treatment plan.2.The patient’s aesthetic perception improved with the procedure of orthodontic treatment. We should pay attention to the changes in patient’s aesthetic psychology and behavior in orthodontic treatment, adjust the treatment program timely and accordingly, and to enhance communication with patients to improve patients’ satisfaction.3.Class â…¢ was considered to be the worst beauty for orthodontic patients, followed by class â…¡1, then class â…¡2and class â… patients.Patients saw an aesthetic improvement following orthodontic treatment in Class â… , Class â…¡ division1, and Class â…¡ division2patients. This aesthetic improvement was significant. But there is no aesthetic improvement in Class â…¢. Therefore, orthodontists should be aware of the fact that expectations of patients and their parents can only be fulfilled to a certain degree. Especially for Class III patients, in which, no significant improvement of facial aesthetics after treatment was found, orthodontists should be cautious with promises of aesthetic improvement. |
