Implementation of a Structured Preclinical Simulation Tool for Locator Housing Pick-Up Training

Area of Science:

• Dental Education
• Prosthodontics
• Biomaterials

Background:

• Preclinical dental implant attachment training is challenging for large student cohorts.
• Consistent instruction for Locator housing pick-up exercises requires effective simulation tools.
• Existing methods may not adequately support visualization and interference identification.

Purpose of the Study:

• To develop and implement institutionally produced training tools for Locator housing pick-up exercises.
• To support preclinical instruction for second-year predoctoral dental students.
• To evaluate the effectiveness and learner perceptions of the developed simulation model.

Main Methods:

• Modified typodont-based simulation tools with clear dentures and gypsum models were integrated into the preclinical curriculum.
• Inspection windows, flange evaluation, and disclosing materials were used to verify denture seating and identify interferences.
• Autopolymerizing acrylic resin was used for housing incorporation, with components designed for reuse.

Main Results:

• The simulation tools allowed visualization of seating conditions and identification of misalignment.
• Student surveys indicated favorable perceptions (mean 4.5-4.9/5) of the exercise and its organization.
• The model proved durable and cost-effective, with minimal replacement needs across academic cycles.

Conclusions:

• A structured simulation approach offers an effective alternative for delivering Locator housing pick-up training in high-volume preclinical settings.
• The developed model facilitates repeated implementation and consistent training across academic cycles.
• This method enhances the preclinical learning experience for dental implant procedures.
