Determination of Incisal Point as Anterior Guide to Transfer Maxillary Casts to Articulator: A Pilot Study
چکیده:   (337 مشاهده)
Objectives Despite the importance to use face-bow record for transferring maxillary cast to articulator some dentists
use average points to avoid the time taken and ease of use. The location of incisal point could help to set the maxillary
cast or denture in an appropriate position in mounting stage. This study was designed to determine the incisal point
location in antero-posterior and vertical dimensions in different facial forms and genders.

Methods Dental casts were obtained from the maxillary jaw of 44 dental students (male and female) and subsequently
transferred to the articulator using an ear bow. The three dimensional location of the incisal point in relation to
condylar axis was determined using a Coordinated Measuring Machine (CMM).Collected data were compared between
male and female participants as well as those of oval, squared and tapered faces. For data analysis Student t test was
employed to make the comparisons.

Results The mean distance between the incisal point and the center of the condylar axis in antero-posterior and
vertical dimensions was 81.28 mm and 42.85 mm respectively. The mean antero-posterior distance was significantly
higher among male students (Ρ<0.05). The mean vertical dimensions did not show any significant difference between
male and female students (P>0.05). In square facial form, the mean antero-posterior distance was significantly higher
compared to the ovoid facial form (P<0.05).

Conclusion The differences on incisal points were significant between the two genders only in antero-posterior
dimension. A similar finding was noted on square facial form when compared to ovoid facial form. The incisal point
was more consistent with the Frankfurt mounting platform compare to Bonwill index.
