IS THERE A RELATION BETWEEN ALVEOLAR RIDGE DIMENSIONS AND BUCCAL UNDERCUT IN THE ANTERIOR MAXILLA?

Abstract Aim: The aim of this study was to investigate of the relation between the alveolar ridge dimensions and buccal undercut in the anterior maxilla. Material and Methods: Cone-beam computed tomography images of 150 patients (97 females, 53 males), aged between 16-40 years having full anterior dentition at the maxilla were evaluated. Six-hundred cross-sectional images were obtained from the regions between central, lateral and canine teeth in the right and left maxilla. The alveolar height and width, and the presence and depth of buccal undercut in these regions were assessed. Results: Results: It was found that the prevalence of buccal undercuts in different regions ranged from 74% to 84% on average. Compared to males, the presence of buccal undercut was found to be significantly higher in females in the regions of between right lateral-canine teeth, left central-lateral teeth and left lateral-canine teeth (p<0.05). A significant positive correlation was determined between alveolar height and coronal alveolar width with buccal undercut depth for all the regions in females (p<0.01). However, a significant positive correlation was only found between coronal alveolar width and buccal undercut depth in the regions of between right central-lateral teeth, left lateral-canine teeth (p<0.05) and right lateral-canine teeth (p<0.01) in males. Conclusion: The dimensions of the alveolar ridge had an effect on the buccal undercut depth. The buccal undercut depth increased when alveolar height and coronal alveolar width increased in females, however it increased only when the coronal alveolar width increased in males.

Öz Amaç: Bu çalışmanın amacı maksilla anterior bölgede alveoler kret boyutları ile bukkal andırkat arasındaki ilişkinin araştırılmasıdır. Gereç ve Yöntem: Maksillada tam anterior dentisyona sahip, 16-40 yaşları arasındaki 150 hastaya (97 kadın, 53 erkek) ait konik ışınlı bilgisayarlı tomografi görüntüleri değerlendirildi. Sağ ve sol maksillada santral, lateral ve köpek dişleri arasındaki bölgelerden altı yüz krosseksiyonel kesit görüntüsü elde edildi. Bu bölgelerde alveoler kret yüksekliği ve genişliği ile bukkal andırkat varlığı ve derinliği değerlendirildi. Bulgular: Farklı bölgelerde bukkal andırkat görülme sıklığının ortalama% 74 ile % 84 arasında değiştiği bulundu. Kadınlarda sağ lateral-kanin, sol santral-lateral, sol lateral-kanin dişler arası bölgelerde bukkal andırkat varlığı erkeklere kıyasla anlamlı olarak daha yüksek bulundu (p<0.05). Kadınlarda tüm bölgelerde alveoler yükseklik ve koronal alveoler genişlik ile bukkal andırkat derinliği arasında anlamlı pozitif korelasyon belirlendi (p<0.01). Bununla birlikte, erkeklerde sadece sağ santral-lateral, sol lateral-kanin (p<0.05) ve sağ lateral-kanin (p<0.01) dişler arası bölgelerde koronal alveoler genişlik ile bukkal andırkat derinliği arasında anlamlı pozitif korelasyon bulundu (p<0.01). Sonuç: Alveoler kret boyutları bukkal andırkat derinliği üzerinde etkili olmuştur. Kadınlarda koronal alveoler genişlik ve alveoler yükseklik arttıkça bukkal andırkat derinliği artmıştır bununla birlikte, erkeklerde sadece koronal alveoler genişlik arttıkça bukkal andırkat derinliği artmıştır.
