Skeletal Muscle Anatomy

Skeletal Muscle Anatomy

Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

Area of Science:

Dental Education
Anatomy Education
Medical Technology

Background:

Three-dimensional (3D) printing innovations include portable 3D pens with educational potential.
The efficacy of 3D pens in teaching prosthodontic anatomy, specifically the muscles of mastication, is currently unexplored.
Assessing 3D pens' impact on student comprehension of masticatory muscles is crucial for advancing dental education.

Purpose of the Study:

Investigate the effectiveness of 3D pens in prosthodontic education.
Compare student understanding of mastication muscles using 3D pens versus traditional 2D diagrams.
Gather student feedback on the use of 3D pens for anatomical learning.

Main Methods:

A prospective randomized controlled interventional study was conducted with two groups: case (3D pen) and control (2D diagrams).
Both groups received instruction on the muscles of mastication.
The case group traced muscles on a 3D-printed skull using 3D pens; the control group drew diagrams. Pre- and post-tests assessed knowledge, with Mann-Whitney test for score comparison.

Main Results:

The 3D pen group achieved a significantly higher mean posttest score (8.65) compared to the traditional group (7.48).
This indicates a superior learning outcome for the 3D pen intervention in understanding mastication anatomy.
The results highlight the potential of 3D pens to enhance knowledge acquisition.

Conclusions:

3D pens are effective supplementary tools for teaching anatomical structures like the muscles of mastication.
Integrating 3D pens and similar technologies can foster innovative and engaging teaching methods in dental education.
This approach may improve student engagement and retention of complex anatomical information.
