ABSTRACT
Aim This study evaluated whether the occlusal plane measurements
on digital photographs were reliable for the reconstruction
of occlusal plane.
Methods Forty-two subjects (25 female and 17 male subjects,
aged 19 to 30 years) with all teeth and Angle Class I participated.
Irreversible hydrocolloid impressions were made and the casts
were poured in dental stone (ISO Type I) and finally mounted in
the S.A.M. 2 “P”, articulator (S.A.M. Praezisiontechnik, GmbH,
Munich, Germany) by a quick mount face-bow transfer. Lateral
digital photographs were taken from a distance of 1.5 m in a natural
head position with a subject in erect posture. A Fox plane was
placed over the maxillary dental arch. A quick-mounting face-bow
was positioned. The angles between the articulator horizontal
plane and the occlusal plane (AHP-OP), as well as those between
the face bow and the Fox plane (FB-FP) were measured, and the
significance of the difference between the means was tested by the
t-test (p
