Development of a Gingiva Model With Periosteum for Dental Students Using 3D Printing Compared to Knowledge-Related...

Area of Science:

• Dental Education
• Surgical Simulation
• Biomaterials

Background:

• Existing dental training models lack essential features like strength, flexibility, and periosteum.
• There is a significant need for improved gingiva models to meet the demands of dental education.
• This study addresses the gap by developing a novel gingiva model tailored for student training.

Purpose of the Study:

• To develop and evaluate a new gingiva model for dental students.
• To assess the suitability of the model for practicing various dental procedures.
• To compare student and expert performance using different model designs.

Main Methods:

• Four distinct gingiva model designs were created using various materials.
• Models were evaluated with and without periosteum and punch features.
• Oral surgeons and dental students across different years tested and rated the models.

Main Results:

• The model incorporating periosteum and simulated alveolus was preferred by all participants.
• Participants found this model to be the most realistic and beneficial for skill development.
• Performance was similar across groups, with a slight advantage for more experienced participants.

Conclusions:

• The developed periosteum model, with or without punches, is recommended for dental students.
• The model offers versatile practice opportunities adaptable to varying experience levels.
• Its ease of production and design flexibility make it suitable for preclinical and clinical training.
