Dental Orta Hat Simetri-Asimetrisinin Dentofasiyal Estetik Algı Üzerine Etkisi

Öz

Gülümseme sözsüz iletişimde etkili olup kişiye yönelik izlenimde önemli bir rol oynar. Estetik diş hekimliği uygulamalarında gülüş analizi tedavi yaklaşımının en önemli parçasıdır. Dental orta hat, iki santral kesici diş arasındaki temas yüzeyi olarak tanımlanır ayrıca anterior dişlerin konumlandırılmasında dikkate alınması gereken estetik faktörlerinden biridir. İdeal bir dental orta hat, dental kompozisyonda arzu edilen bir uyum ve birlik etkisini yaratır. Özellikle gülümseme simetrisinden söz edildiğinde, dental orta hat pozisyonunun önemi, dişsiz anterior bölgeyi restore ederken bir ön koşul oluşturmaktadır. Gülüş analizinde dental orta hat asimetri ve simetrisi özellikle değerlendirilmelidir. Bu çalışmadaki amacımız; gülüş simetrisinde rol oynayan dental orta hat asimetri ve simetrisinin fasiyal estetik algısı üzerindeki etkisini değerlendirmektir.

The Effect Of Dental Midline Symmetry-Asymmetry On Dentofacial Aesthetic Perception

Öz

Smiling is effective in nonverbal communication and plays an important role in the impression of the person. Smile analysis is the most important part of the treatment approach in aesthetic dentistry applications. The dental midline is defined as the contact surface between two central incisors and is one of the aesthetic factors to consider when positioning anterior teeth. An ideal dental midline creates the desired effect of harmony and unity in the dental composition. Especially when talking about smile symmetry, the importance of dental midline position is a prerequisite when restoring the edentulous anterior region. Dental midline asymmetry and symmetry should be especially evaluated in smile analysis. Our aim in this study; To evaluate the effect of dental midline asymmetry and symmetry, which plays a role in smile symmetry, on facial aesthetic perception.
