Abstract

Amaç: Bu çalışmanın amacı antropometrik noktalar arasındaki
mesafeyi kullanarak oklüzal dikey boyutu yüksek hassasiyetle hesaplayabilen
matematiksel bir formülün elde edilmesidir.

Gereç
ve Yöntem:  Çalışmaya yüz kırk sekiz gönüllü (74 erkek,
74 kadın) dahil edildi. Subnasion-Menton ve yüzdeki diğer on altı mesafeyi
ölçmek için dijital bir kumpas kullanıldı. Subnasion-Menton mesafesini tahmin
etmek için korelasyon ve regresyon analizi yapıldı. Regresyon analizi ile elde
edilen verilerle okluzal dikey boyutu açıklayan matematiksel bir formül
geliştirildi. Formülün doğruluğu bireylerden elde edilen veriler üzerinde test
edildi.

Bulgular: Subnasion-Menton mesafesi Tragus-Tragus, Pupil-Pupil,
Inner Canthus-Inner Canthus, Extra Chantus-Extra Chantus, Tragus-Chelion,
Pupil-Nose Tip, Pupil-Subnasion
, Pupil-Chelion, Tragus-Extra
Chantus mesafeleri ile anlamlı korelasyon gösterdi. Toplam R², 0.5926
idi. Elde edilen formül ile katılımcıların SnMe uzaklıklarının hesaplanmasında %
54 doğruluk oranı gözlendi. Subnasion Menton mesafesi, 1 mm hata payıyla % 61,
2,5 mm hata payıyla % 73 oranında doğru olarak hesaplandı.

Sonuç: Yüzdeki antropometrik noktalar arasındaki mesafelerin
bir kısmı oklüzal dikey boyutla anlamlı bir ilişkiye sahiptir.. Bu mesafelerin
uzunluk değerlerinin istatistiksel analizi ile oluşturulan matematiksel bir
formül, oklüzal dikey boyutun hesaplanmasında kullanılabilir.

Developing A Mathematical Formula to Estimate The Occlusal Vertical Dimension.

Abstract

Aim: The aim of this study is to obtain a mathematical
formula that can calculate occlusal vertical dimension with high accuracy,
using the distance between the anthropometric points.

Material
and Methods:
One hundred and forty-eight subjects (74 males, 74 females) were included in
the study. A digital calliper was used to measure the Subnasion-Menton (SnMe)
and the sixteen other distances on the face. The correlation and regression
analysis were performed to predict the SnMe distance. A mathematical formula
was developed to explain the occlusal vertical dimension with the data obtained
by the regression analysis. The accuracy of the
formula was tested on data from individuals.

Results: Tragus-Tragus, Pupil-Pupil,
Inner Canthus-Inner Canthus, Extra Chantus-Extra Chantus, Tragus-Chelion,
Pupil-Nose Tip, Pupil-Subnasion
, Pupil-Chelion, Tragus-Extra
Chantus Vertical distances had a significant correlation with SnMe. The Total R²
was  0.5926. With this formula, 54%
accuracy was observed in calculating participants' SnMe distances. The SnMe
distance was estimated to be 61% with an error margin of 1 mm and 73% with an error
margin of 2.5 mm.

Conclusions: Some of the distances between the anthropometric
points on the face have a significant relation with the occlusal vertical
dimension. A mathematical formula, to be generated by the statistical analysis
of the length values of these distances, can be used to calculate the occlusal
vertical dimension.
