Study Notes

Complications in Complete Denture Wearers

Flabby Ridge: Commonly occurs in the upper anterior region due to severe bone resorption replaced with fibrous tissue, compromising denture stability and aesthetics.
Aetiology: Associated with the presence of lower natural teeth and factors influencing bone metabolism, warranting regular monitoring of affected patients.

Management Approaches

Surgical Removal: Advocates recommend removing fibrous tissue to create a stable ridge; this can reduce size but increases prosthetic bulk.
Non-Surgical Treatment: Focuses on impression techniques:
- Mucodisplacive technique: Compacts flabby tissue for support.
- Mucostatic technique: Maximizes retention without compressing tissue.

Denture Breakages

Prevalence: Midline fractures account for 29% of upper denture repairs; 33% involve debonded teeth.
Types of Fracture:
- Fatigue of Acrylic Resin: Caused by repeated flexing over time, starting near upper centrals, common in 3-year-old dentures, leading to midline fractures.
- Impact Fractures: Occur from dropping the denture or trauma, requiring identification of causes before repairs.

Causes of Fractures

Denture Factors: Include stress concentrators, absence of labial flange, incomplete polymerization, previous repairs, ill-fitting dentures, and inadequate relief.

Managing the Gag Reflex

Challenges: Accurate impressions are critical; techniques to minimize gag reflex include:
- Conscious sedation
- Acupuncture during procedures
- Hypnosis for patient comfort
- Training dentures to reduce intolerance

Burning Mouth Syndrome (BMS)

Prevalence: Affects 5-7% of the adult population, predominantly women around 60 years old, with symptoms often localized to the tongue and upper denture-bearing tissues.
Classification of BMS:
- Type 1: Symptoms start in the day, common in those with deficiencies and poor denture designs.
- Type 2: Symptoms present on waking and persist all day, often linked with chronic anxiety.
- Type 3: Symptom-free days with burning in atypical locations, possibly due to palatal thickening.

Speech and Denture Fit

Dental Relationships:
- Contact of lower lip with upper anterior teeth affects sounds /f/ and /v/.
- Tongue contact with posterior teeth is crucial for English consonants like /th/, /d/, and /s/.
- Overly high occlusal planes can cause clattering of teeth during speech, impacting communication.

Key Considerations

Regular review and customized management approaches are essential for improving the quality of life for complete denture wearers.
Effective communication between patient and dental professionals enhances treatment experiences and outcomes.
