Abstract

The Self-Guided Instructional Material-Complete Denture Record Bases With Flanges Augmented With Flexible Material Module is an instructional internet resource that identifies a lesson, with goals, and arranges an online experience that supports a learning activity—a simple, quick and inexpensive technique for making denture record base flanges augmented with resilient liner that takes advantage of the elastic properties of tissue conditioner, available anatomic undercuts in working casts, and the rigidity of record base resin to create stable, well-fitting, and comfortable record bases for recording maxillomandibular jaw relations. In this module, we fabricate a polymethyl methacrylate record base with flanges augmented with resilient tissue conditioner liner. The technique takes advantage of the elastic properties of tissue conditioner, available undercuts in working casts, and the rigidity of record base resin to create stable, well-fitting, and comfortable record bases for recording maxillomandibular jaw relations. The method of fabrication is the indirect method (outside the patient’s mouth) where a maxillary record base is fabricated on a patient’s working cast. Alternative materials for use in making record bases are presented. The techniques outlined have been deployed successfully by undergraduate dental students in two university preclinical simulation laboratory and clinical laboratory settings. During that time, 18 junior and senior dental students fabricated augmented record bases for their clinic patients. Students were asked to self-assess their work using our self-assessment rubric. A review of 436 self-assessment forms completed by preclinical students revealed that 55 (12.6%) were in complete agreement with evaluations completed by facilitators. Three hundred seventy-three student assessments (85.6%) contained one to three disagreements with criteria assessed by facilitators; 8 student assessments (1.8%) contained six to seven disagreements. The data seems to indicate that a successful outcome was achieved when color photographs and step-by-step instructions were used in the simulation laboratory to guide students in learning to produce stable and retentive complete denture record bases with augmented flanges.


Educational Objectives

By the end of this session, learners will be able to:

  1. Demonstrate a simple technique that can be used by dental practitioners, laboratory technicians, dental faculty, and students to fabricate comfortable denture record bases with flanges augmented with soft tissue conditioner that engage undercuts in edentulous ridges for improved retention and stability.
  2. Recognize the advantages of using soft tissue conditioner with autopolymerizing acrylic resin to produce record bases that are strong and rigid.
  3. Understand how to handle and store record bases with flexible augmented flanges to ensure that they remain resilient and uncontaminated.
  4. Recognize that the technique can be used also to construct record bases composed of visible light cured resins for patients and dental personnel with a history of dermatitis caused by exposure to polymethyl methacrylate monomer.
