This study evaluated impression materials and mannequin positions for partial denture fabrication. Some materials showed poor adhesion to artificial mucosa, and specific head/back positions affected upper jaw impressions, particularly on the palate.

Area of Science:

  • Dental materials science
  • Prosthodontics
  • Clinical simulation

Background:

  • Mannequin exercises are increasingly vital in dental education for partial denture fabrication.
  • Assessing the accuracy of impression materials on simulation models is crucial for effective training.

Purpose of the Study:

  • To evaluate the efficacy of various impression materials on artificial mucosa for partial denture simulation.
  • To determine the influence of mannequin head and back positioning on impression accuracy.

Main Methods:

  • Nine impression materials were tested for adhesion and setting on artificial mucosa.
  • Mannequin head and back inclinations were varied across four positions.
  • Acquired models were sectioned and examined for impression quality.

Main Results:

  • Most tested impression materials exhibited poor adhesion to artificial mucosa; some showed incomplete setting.
  • Specific mannequin positions (median sagittal C, lateral S) significantly altered upper jaw impressions, especially in the palatal molar region.

Conclusions:

  • Material selection and patient/mannequin positioning are critical factors in achieving accurate impressions for partial dentures using simulation models.
  • Further research is needed to identify optimal materials and positioning for simulation-based dental training.
