Abstract
Eighty dentate students participated as a study group and another 74 as a control group. The aim was to determine a
possibility to reconstruct maxillary frontal teeth dimensions by use of certain hard palate dimensions. The height (IH)
and the incisal (IW), contact point (CtW) and cervical width (CW) of maxillary central incisors (MCI), hamular width
(HW) and the distance between the incisive papilla and the palatine foveas (IP-FP) were measured on the maxillary casts.
CtW of maxillary lateral incisors and canines were measured too. In the study group the ratios were computed: HW/IW
(5.71), HW/CtW (5.69), HW/CW (5.51) and IP-FP/IH (4.76). These ratios were multiplied by incisor’s dimensions (obtained
from the control group) to calculate the hard palate dimensions. No significant differences were obtained between
the calculated and the measured (study group) hard palate dimensions. Furthermore, there was no significant difference
between the HW and the Sum of contact-point widths of all maxillary frontal teeth (p>0.05) in the both groups. The results
revealed: 1. MCI width and height might be calculated by dividing dimensions of a patient’s hard palate and appropriate
ratio; 2. hamular width dimension can be used as a selection guide for the sum of contact-point widths of six
maxillary frontal teeth.
