Questions and Answers

What is a common complication associated with complete dentures that could lead to patient dissatisfaction?

  • Difficulty in aligning the jaw during impressions.

  • Complete replacement of the denture base structure.

    • What is a significant reason for rebasing a denture?

  • To renew the color and appearance of the denture.
  • To change the position of the teeth for better aesthetics.
  • To increase the lip support provided by the denture.
  • Due to significant tissue changes or structural deterioration. (correct)

    Study Notes

    Removable Prothesis: Complete Denture

    • Diagnosis: Essential initial assessment involves a thorough oral examination:

      • Reviewing medical history
      • Intraoral examination (teeth, gums, bone level, mouth structures)
      • Extraoral examination (jaw joints, facial symmetry)
      • Radiographic analysis (x-rays) evaluating bone resorption, impacted teeth, etc.
      • Assessing patient needs and expectations regarding aesthetics, function, and comfort.
      • Considering the patient's overall health, influencing treatment or contraindicating certain methods.
      • Evaluating patient's ability, tolerance, and compliance throughout treatment.

    • Impression Taking: Crucial for accurate denture construction:

      • Accurate impression materials and techniques capture soft tissues and underlying bone structures.
      • Materials, like alginate, irreversible hydrocolloids, polyether, or silicone, vary by case complexity.
      • Proper mounting procedures are vital to avoid inaccuracies.
      • Avoiding muco-compressive pressure is crucial; this could involve adjusting mounting and/or impression materials.

    • Jaw Relation Records: Establishing the correct relationship between maxillary and mandibular arches:

      • Bite registration materials and techniques establish proper vertical dimension.
      • Tools include wax rims, articulators, and face bows.
      • Precise recording of centric occlusion and other jaw relationships is essential.
      • Accurate centric relation recording, if possible, is preferred over centric occlusion.
      • These records allow for a properly fitting complete denture.

    • Try-in: Trial fitting the denture before final delivery:

      • Patient feedback and adjustments are crucial before final delivery.
      • Final evaluation considers fit, aesthetics, comfort, speech, and masticatory efficiency.
      • Refinements tailor the denture to patient needs.

    • Delivery: Presenting the final denture to the patient:

      • Explaining function and care instructions to the patient.
      • Emphasizing regular maintenance, hygiene, and professional check-ups to address potential issues.

    • Complications: Potential issues in complete denture fabrication and adjustment:

      • Poor fit causing sore spots/pain.
      • Difficulty chewing/speech problems.
      • Esthetic concerns.
      • Unstable/ill-fitting denture bases.
      • Insufficient lip support/posterior instability.
      • Tissue irritation.
      • Inability to achieve accurate centric relation.
      • Patient dissatisfaction/non-compliance.
      • Psychological impact affecting social integration.

    Relining and Rebasing

    • Relining: Partial or complete denture repair for comfort and tissue changes:

      • Replaces the tissue surface of the denture base material to address tissue changes.
      • Materials include soft liners and/or relining materials like acrylic resin.
      • Applied over the existing denture base, if needed.
      • Allows re-adjustment/renewal of fit without replacing the whole denture.
      • Suitable for patients with tissue changes like bone resorption.

    • Rebasing: Re-creating the denture base due to significant changes or deterioration:

      • Completely replaces the denture base structure to improve fit and function.
      • Re-impressions meticulously consider changes in oral architecture.
      • Materials & techniques match normal denture fabrication procedures.
      • Usually for worn-out, structurally compromised dentures, or significantly improved fit/repair.
