Competency: 20

Details

Design, manufacture and evaluate a range of dentures, obturators and mandibular prostheses (following hemi/partial mandiblectomy) for postoperative oral rehabilitation following palatal resection.

Considerations

Dentures and Obturation

• Classification of post-surgical defects.
• Dental materials selection, baseplates, dental alloys for clasping.
• Materials and techniques used in obturator construction.
• Design features of obturator prostheses.
• Occlusal schemes for patient requiring complete dentures and obturators.
• Use of dental implants.
• Type and extent of records required for individual assessment.
• Regulatory requirements for dentures, obturators and mandibular prostheses.
• Legal, ethical, professional and technical issues associated with the provision of dentures and obturators.
• Classification of post-surgical defects, effect of defect on prosthodontic design principles.
• Managing restricted opening utilising devices and interventions.
• Materials and techniques used in obturator construction.
• Design features of obturator prostheses.
• Open box, hollow box, glove obturators, obturator retention and soft palate obturation.
• Surface finish of prostheses and microbial colonisation and degradation of silicone elastomers.
• Intermediate obturator prostheses.
• Definitive obturator prostheses
• Prosthodonists/Restorative dentistry involvement in planning and assessments.
• Occlusion in relation to complete and partial prosthodontics for maxillary defects.
• Alternative denture retention units.
• Two-part bolt, split post and tube, hinged sectional and swing lock designs.
• Use of implants and precision attachments.
• Criteria for clinical presentation and patient use.
• Occlusal schemes for patient requiring:
  • complete dentures and obturators
  • neutrocentric
  • monoplane
  • lingualised occlusion
  • balancing ramps
  • Gerber based.
• Two-part dentures, design criteria for patients with microstomia.
