Brief Summary

3D modeling enables medical professionals or students to better understand complex structures. In many studies, 3D printed models have been used in the training, treatment and surgery of medical disciplines such as neuroscience, cardiovascular surgery and otolaryngology. In addition, 3D modeling allows patients' magnetic resonance imaging (MRI) and computed tomography (CT) images to be transferred to 3D printers to print these complex structures.

Outcome Measures

Primary Outcomes (1)

• Quiz Scores

  In order to measure the anatomical terminology and general knowledge of the students, a general test will be applied before the pre-test and the groups will be distributed according to this test score. Then, a total of 20 theoretical and 20 practical questions of 10 questions each will be prepared to be used in the pre-test and post-test. The questions will be under the headings of bony prominences, neighborhood, important structures, adhesion sites and function.

3D Printed Model Group Enlarged %100

OTHER

carpal bone models printed on a 3D resin printer and enlarged by 100% will be used for students' anatomy practical training. Each student will examine the models with direct manipulation for 15 minutes after the theoretical lecture.

Control Group

ACTIVE COMPARATOR

Standard carpal bone models will be used for student's anatomical practical training. Each student will examine the models with direct manipulation for 15 minutes after the theoretical lecture.

Other: Anatomy Training with Conventional Carpal Models

Interventions

Anatomy Training with Conventional Carpal Models OTHER

After completing the general terminology part of the anatomy education in the first year, the participants will be recruited without moving on to the hand section of the upper extremity. Participants will undergo a 2-hour extra-curricular training, 60 minutes theoretical and 60 minutes practical. The training period will consist of 60 minutes of practical and theoretical lectures to be the same as the time allocated in the normal curriculum of the region. A 60-minute theoretical lecture on the anatomy of the carpal bone supported by 2-dimensional anatomical pictures will be given to both groups at the same time. They will then have a 60 minutes practical lesson with a standard sized printed model.

After completing the general terminology part of the anatomy education in the first year, the participants will be recruited without moving on to the hand section of the upper extremity. Participants will undergo a 2-hour extra-curricular training, 60 minutes theoretical and 30 minutes practical. The training period will consist of 60 minutes of practical and theoretical lectures to be the same as the time allocated in the normal curriculum of the region. A 60-minute theoretical lecture on the anatomy of the carpal bone supported by 2-dimensional anatomical pictures will be given to both groups at the same time. Then they will take the practical lesson with carpal bones printed with 50% magnification on a 3D printer for 60 minutes.
