Area of Science:

  • Dental Prosthodontics
  • Biomaterials Science

Background:

  • Poor denture base adaptation can lead to discomfort and the need for relining.
  • Quantitative assessment of denture fit is crucial for optimizing patient outcomes.

Purpose of the Study:

  • To quantitatively evaluate denture base adaptation to mucosa using a non-setting pressure-indicating paste.
  • To determine the relationship between the quality of denture fit and the necessity for denture relining.

Main Methods:

  • 123 dentures from 70 partially edentulous patients were analyzed.
  • A non-setting pressure-indicating paste was applied to denture surfaces contacting the alveolar crest.
  • Denture adaptation was assessed by measuring the paste spread width, with logistic regression and ROC curve analysis used for statistical evaluation.

Main Results:

  • The paste spread width was inversely proportional to the gap between the denture and mucosa.
  • Statistically significant associations were found between the need for relining, paste spread width, and duration of denture use.
  • A paste spread width of 2.0 mm or less indicated a need for relining, with 85.1% sensitivity and 75.0% specificity.

Conclusions:

  • The spread width of pressure-indicating paste is a valuable quantitative parameter for assessing removable denture base fit.
  • This method can effectively discriminate the need for denture relining, aiding clinical decision-making.
