Area of Science:

  • Dentistry
  • Dental Materials Science

Background:

  • Accurate complete denture impressions are crucial for optimal patient function and comfort.
  • Conventional impression techniques can present challenges in capturing all necessary details, particularly border molding and mucosal surfaces.

Purpose of the Study:

  • To describe a novel and convenient technique for complete denture impressions.
  • To evaluate the properties of two newly developed silicone impression materials for this application.

Main Methods:

  • Utilized a heavy-bodied silicone material for simultaneous border molding, featuring automatic mixing systems.
  • Employed a light-bodied silicone material with enhanced flow properties for superior mucosal detail capture.
  • Assessed material characteristics including elasticity, carvability, viscosity control, and flow during intraoral seating.

Main Results:

  • The heavy-bodied silicone allowed for easy, even application and facilitated correction of excess or deficient material.
  • The light-bodied silicone demonstrated improved flow over conventional materials, ensuring excellent mucosal detail reproduction.
  • The combined technique offers a convenient and effective method for complete denture impressions.

Conclusions:

  • The newly developed silicone impression materials provide a convenient and effective technique for complete denture fabrication.
  • This method enhances the accuracy of border molding and mucosal detail, potentially improving denture fit and patient satisfaction.
