Abstract
The aim of this study was to re-examine Leon Williams geometric theory and to find
the degree of correspondence between the face and the tooth form in the population of
Zenica, Bosnia and Herzegovina. Two thousand individuals with intact frontal teeth, in
age between 17 and 24 years, were measured for 3 horizontal distances on the face: temporal
width (Ft-Ft), zygomatic width (Zyg-Zyg) and gonial width (Go-Go) and for 3 horizontal
distances on the both upper incisors: cervical width (CW), contact point width
(CPW) and incisal width (IW). The length of the face (Tr-Gn) as well as the length of the
central maxillary incisors were also measured. The results revealed: 1. Men had significantly
larger dimensions for all facial and tooth dimensions (p < 0.05) than women, except
for the cervical tooth width (p > 0.05); the left and the right central incisors were of
identical dimensions and forms (p > 0.05). 2. The width of upper central incisors were
smaller approximately 1.5 mm than in west Europeans. 3. Upon the relation between
the 3 horizontal dimensions measured on the face and upper maxillary incisor, 11 facial
forms and 10 upper central tooth forms could be recognised in the study population, but
98% of the population had only 3 tooth and face forms. Face shapes: oval face – 83.3%,
square-tapered face – 9.2% and tapered face – 7%; tooth forms: tapered-square incisor –
53%, oval incisor – 30%, tappered incisor – 16%. 4. Reversed and enlarged tooth form
was in line associated with the facial form in only 30%, while the most common combination
was of the oval face form and the tapered-square central incisor (45%). 5. These
results disapprove William’s theory and may be helpful for the choice of artificial teeth
in complete denture construction and the dental industry.
