Abstract

Abstract:

Objective

To study the effect of 3dMD^? three-dimensional photogrammetry on orthodontics experimental teaching program.

Methods

A total of 24 students from Stomatology Grade 2013, Guanghua School of Stomatology, Sun Yat-sen University were randomly divided into two groups. Both groups learnt the two methods of photograph analysis, one group was first taught with traditional teaching method, another with 3dMD^? method and then exchanged. The students were asked to grade both of the traditional and 3dMD^? teaching methods, and questionnaire survey was performed.

Results

The scores of the traditional method and 3dMD^? method were (8.5 ± 0.75) and (7.1 ± 1.13) respectively, and the difference was statistically significant (t = 2.762, P = 0.028) . In the students′ point of view, the advantages of 3dMD^? teaching method were mainly "novel and interesting" and "beneficial for the understanding of orthodontic cases" .

Conclusion

Three-dimensional photogrammetry is helpful to improve the effect of orthodontic teaching.

Key words: Imaging, three-dimensional, Photogrammetry, Orthodontics
