The Impact Of Orthodontic Relapse on The Perception of Smile Aesthetics: An Evaluation by Patients Undergoing Orthodontic Treatment

Öz

Objectives: To evaluate the impact of potential tooth movement following orthodontic relapse on the aesthetic perception of patients undergoing orthodontic treatment. Materials and Methods: Frontal and lateral smiling photographs of one female and one male volunteer who had previously received orthodontic treatment and hade a regular profile with class I occlusion and class I skeletal pattern were evaluated. Variables included in the evaluation made by 200 laypeople who had undergone orthodontic treatment using photographs of male and female smiles: median diastema, overbite change, central tooth extrusion, labiolingual inclination of incisors and labiolingual translation of lateral teeth. Evaluators rated the overall attractiveness and acceptability of each photo using a scale of 0 to 10 (0: least attractive; 10: most attractive). Results: There were statistical differences in aesthetic ratings between female and male evaluators. Median diastema and central tooth extrusion of 0.5 mm or larger affected female and male model attractiveness scores. The acceptable range for overbite, maxillary incisor inclination, and labiolingual translation of the maxillary lateral tooth varied between the female and the male models. Conclusions: Female evaluators were more critical in aesthetic evaluation. 0.5-mm median diastema and central tooth extrusion adversely affected smile aesthetics. Although there were differences between male and female models, raters tolerated limited overbite (0 mm) less than increased overbite. Moreover, the lingual inclination of the upper incisors was more acceptable than labial movement. Perception of labiolingual translation of the upper lateral tooth varied depending on the perspective and model being evaluated.

Ortodontik Nüks Sonrası Değişikliklerin Ortodonti Hastalarının Gülümseme Estetiği Algısına Etkisi

Öz

Amaç: Ortodontik relaps sonrası diş hareketinin, ortodontik tedavi gören hastaların estetik algıları üzerindeki etkisini değerlendirmek. Gereç ve Yöntemler: Daha önce ortodontik tedavi görmüş, Sınıf I oklüzyon ve iskelet ilişkisine sahip sahip düzgün profilli bir kadın ve bir erkek gönüllünün frontal ve lateral gülümseme fotoğrafları değerlendirildi. Kadın ve erkek gülümseme fotoğrafları kullanılarak, ortodontik tedavi görmüş 200 kişi tarafından değerlendirilen değişkenler: median diastema, overbite değişimi, santral diş ekstruzyonu, kesici dişlerin labiolingual inklinasyonu ve lateral dişin labiolingual translasyonu. Değerlendiriciler, her fotoğrafın genel çekiciliğini ve kabul edilebilirliğini 0'dan 10'a kadar bir ölçek kullanarak derecelendirdi (0: en az çekici; 10: en çekici). Bulgular: Kadın ve erkek değerlendiriciler arasında estetik derecelendirmelerde istatistiksel farklılıklar mevcuttu. Kadın ve erkek model çekicilik skorları, 0.5 mm veya daha büyük median diastema ve santral diş ekstrüzyonundan etkilendi. Overbite, maksiller kesici diş inklinasyonu ve maksiller lateral dişin labiolingual translasyonu için kabul edilebilir aralık, kadın ve erkek model arasında farklılık gösterdi. Sonuç: Kadın değerlendiriciler estetik değerlendirmede daha eleştireldi. 0.5 mm median diastema ve santral diş ekstruzyonu gülümseme estetiğini olumsuz etkiledi. Erkek ve kadın modeller arasında farklılıklar olmasına rağmen, değerlendiriciler sınırlı overbite’ı (0 mm) artan overbite’a göre daha az tolere etti. Ayrıca üst kesici dişlerin lingual eğiminin labial eğime göre daha kabul edilebilir olduğu gözlendi. Üst lateral dişin labiolingual translasyon algısı, değerlendirilen perspektife ve modele bağlı olarak değişiklik gösterdi.
