Use of digital photography in the reconstruction of the occlusal plane orientation

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.
