Background and Aim: Esthetics
is one of the prosthetic treatment goals. Correct selection of anterior teeth,
regarding size and appearance, results in a successful treatment. Using the
extra oral indicators is a common method to determine the size of the tooth. In
this study, the correlation between the facial widths (in bizygomatic and
intercondylar areas) and the mesiodistal width of maxillary central incisors
was analyzed.
Materials
and Methods:A cross-sectional study was conducted on
100 qualified students, 50 females and 50 males. Two facial widths comprising
Intercondylar width -distance between two approximately Beyron hinge axis- and
bizygomatic width -two most convex points of zygomatic arch- were marked and
measured by a facebow and a digital caliper. Mesiodistal maxillary central
incisors’ widths were measured by a digital caliper. The collected data were
analyzed via Pearson correlation coefficient.
Results:
The mesiodistal width of right central incisor was 8.47±0.56. The mesiodistal
width of left central incisor was 8.54±0.64.The bizygomatic width was
126.15±6.74. The intercondylar width was 131.43±5.41. There was no correlation
between bizygomatic width and central incisors (P>0.05) and a weak
correlation between intercondylar width and central incisors in Iranian
community.
Conclusion: Facial width is not recommended as a
suitable landmark for estimating the mesiodistal width of maxillary central
incisors.
