Designing Dentures

The importance of denture design

A well-designed denture can restore chewing ability, improve speech, have aesthetic appeal and help maintain overall oral health.1

Creating functional and comfortable dentures requires careful custom planning and consideration of the following factors:1

  • Clinical
  • Anatomical
  • Technical

Principles of good denture design

Foundations of good denture design

Three overarching principles form the foundation of good denture design

For good denture design, the three overarching principles are:

  • Retention The denture should be resistant to the forces that can cause it to move away from supporting tissues2,3
  • Stability The denture should be as stable as possible, resisting any lateral movement and avoiding constant reminders of its physical presence in the patient’s mouth.3-5
  • Support The denture should be resistant to the forces that may cause it to move.4

Restricted oral anatomy and denture retention/stability

Restrictions in patient oral anatomy can limit denture retention and stability.5,6Well-fitting denture performance can be limited by patients’ oral anatomy,6 and can be gradually affected by bone resorption over time.6,7

Oral anatomy

Impact of oral anatomy

Factors limiting retention:

  • Surface area defined by individual oral anatomy
  • Gradual physiological bone resorption over time6,7

Patient impact:

  • Reduced denture retention5,7 and stability6
  • Poor chewing ability6,7
  • Decreased denture satisfaction7

Poor denture hygiene can compromise oral health9–11

  • Poor denture hygiene can compromise oral health11-13

    Poor hygiene with partial dentures may compromise the health of remaining natural teeth by:

    • Harboring bacteria which may infect remaining teeth and oral surfaces14-16
    • Encouraging increased plaque accumulation, possibly resulting in caries and periodontitis11,13
  • Up to 80%

    Keeping dentures clean

    Up to 80% of patients use a regular toothpaste to clean dentures12

  • Up to 63%

    Biofilm and calculus

    Up to 63% of patients with full dentures have biofilm and calculus on their dentures.*12

    *In an observational study12

  • Poor denture hygiene may put full and partial denture wearers’ health at risk.11-13

  • Bacteria on denture

    Hygiene-related design principles

    Poor oral health may affect patients’ overall well-being as well as their oral health. Poor denture hygiene may result in infection of remaining teeth and oral surfaces, plaque accumulation, or propose increased health risks, such as pneumonia.14

    Consideration of hygienic principles during the denture design process may help avoid the risk of hygiene-related complications by:3

    • Creating dentures that are easy for the patient to clean and care for
    • Avoiding unnecessary coverage of gingival tissues

Inadequate denture cleaning may lead to denture stomatitis17,18

Up to 88%

Up to 88% of denture wearers do not clean their dentures effectively.19

Up to 67%

Up to 67% of full denture wearers have denture stomatitis.17

Denture stomatitis Still

Denture stomatitis*7

Denture stomatitis is commonly associated with a yeast infection that causes the area underneath the denture to become very red.

Left untreated, it can cause soreness of the mouth and may lead to poorly fitted dentures in the future.17,19

Stomatitis* is caused by microbial biofilm on the denture-fitting surface (rather than the mucosal surface) and poorly fitted dentures.18

The prevalence of denture stomatitis is strongly linked with the amount of denture plaque.17

  • Xerostomia icon

    Xerostomia is a subjective feeling of dry mouth that may result from a decrease in the production of saliva (hyposalivation).9

  • Up to 48% Infographic

    Xerostomia

    In a study, up to 48% of denture wearers suffer from xerostomia.*10

    Causes:9

    • Side effects of medications
    • Radiation therapy
    • Chemotherapy
    • Systemic diseases
    • Diseases of the salivary glands

    *in a study conducted by Toshio et al

  • Xerostomia can limit denture retention

    Impact of xerostomia on denture retention

    Saliva helps to hold dentures in place. Reduced saliva limits the surface tension whereby the dentures have less force to adhere to the ridge. Saliva, along with a well-fitting denture, creates proper adhesion between the ridge and denture (i.e. suction).

Xerostomia

Patient Implications of Xerostomia

Reduced retention of dentures caused by xerostomia predisposes patients to mucosal abrasions and ulcerations5
