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<0.05). Results The mean value of AHP-OP angle was 8.56 ± ; ; ; 3.1 degrees and the mean value of FB-FP angle was 8.80 ± ; ; ; 4.2 degrees. There was no significant difference between the male and the female subjects (p<0.05). There was no significant difference between AHP-OP and FB-FP angles (p<0.05). Conclusion Measurements of occlusal plane inclination from digital photographs could be helpful in future prosthodontic reconstruction treatment.
