Area of Science:

Dental Education
Prosthodontics
Simulation-Based Training

Background:

Complete denture (CD) flange adjustment is a critical post-insertion procedure.
Effective training methods are essential for developing student competencies in this area.
Current training may not fully prepare students for clinical application.

Purpose of the Study:

To introduce a novel simulation model for complete denture flange adjustment training.
To assess the impact of this simulation model on dental students' competencies.
To evaluate improvements across knowledge, cognitive, and psychomotor skill domains.

Main Methods:

A cohort of 100 fourth-year dental students was divided into control and test groups.
The test group received simulation training using modified working casts, in addition to didactic instruction.
Both groups performed flange adjustments on patients, with skills assessed using a checklist.

Main Results:

The test group demonstrated significantly higher overall performance (57.94%) compared to the control group (30.14%) (p < 0.001).
Competency increased in most knowledge and all cognitive skill tasks for the test group.
Improvements in psychomotor skills were observed for about half of the tasks, with specific gender-based differences noted.

Conclusions:

The simulation model significantly enhanced students' overall clinical skills for complete denture post-insertion maintenance.
Simulation training allows students to practice and refine flange adjustment techniques before clinical patient care.
The model shows promise for improving dental student proficiency in complete denture procedures.
