Enhancing Student Learning in Removable Partial Denture Design by Using Virtual Three-Dimensional Models Versus...

Area of Science:

• Dental Education
• Prosthodontics
• Digital Dentistry

Background:

• Traditional preclinical education for removable partial denture (RPD) design relies on paper-based exercises.
• Emerging digital technologies offer potential alternatives for enhancing dental education.

Purpose of the Study:

• To compare virtual 3D casts versus traditional 2D drawings for preclinical RPD design exercises.
• To evaluate the impact on student learning outcomes (scores) and student attitudes.

Main Methods:

• Two groups of students were randomly assigned to complete RPD design exercises using either virtual 3D casts or traditional 2D formats.
• Both Kennedy class II and class IV exercises were utilized, with format assignment varied between exercises.
• Student preferences were assessed via survey, and performance scores were compared using statistical tests.

Main Results:

• No statistically significant difference was found in student learning outcomes (exercise scores) between the virtual 3D and traditional 2D formats.
• Students demonstrated a significantly higher preference for using virtual 3D casts over 2D drawings in all surveyed aspects.

Conclusions:

• Virtual 3D casts offer a preferred learning modality for students in preclinical RPD design, despite not altering learning outcomes.
• Integrating 3D virtual models into the curriculum may enhance student engagement and acceptance of digital tools in dentistry.
