Facial approximation: evaluation of dental and facial proportions with height
Background: Fabrication of complete dentures requires the use of
certain guidelines which are placed on the bite blocks to assist the
clinician to have the maxillary anterior teeth restored to optimal
dento-labial relations, in harmony with the overall facial appearance.
Objective: To explore if any relationship exists between dental and
facial proportions as well as the height of the individuals. Methods:
Two hundred and four dental students of the Obafemi Awolowo University
volunteered to participated in the study. The lower facial height,
inter incisal, inter canine, and intercommisure distances, as well as
the height of the participants were measured. The data were imputed,
analyzed, and reported as simple frequency, means and standard
deviations using the SPSS vs 11. Statistical significance was inferred
at p<0.05. Result: The mean values of all the parameters measured
were significantly higher in males than females. None of the mean
values measured were coincident. However, a significant correlation
exists between intercanine and interincisal distances(r=0.8) while a
weak but significant negative correlation exists between the
intercanine distance and the difference of the intercommisural and
intercanine distances (r=-0.4) Conclusion: The study showed no
relationship between intercanine distance, interincisal distance, lower
facial height, and the height of the participants with the
intercommissural distance. Hence, intercommissural distance may not be
used in marking canine line during bite registration procedure. At
best, 1.75-2.45 cm should be subtracted from the intercommissural
distance to determine the intercanine distance
