Summary

Denture adhesives significantly reduce mandibular denture dislodgment during chewing in patients with severe alveolar ridge resorption. This finding improves denture retention and stability for better oral function.

Area of Science:

  • Dental Prosthetics and Biomaterials
  • Oral Rehabilitation and Maxillofacial Surgery

Background:

  • Severe alveolar ridge resorption in the mandible presents challenges for complete denture retention and stability.
  • Conventional complete mandibular dentures often suffer from dislodgment during functional activities like chewing.
  • Denture adhesives are commonly used to improve denture stability, but their efficacy in specific patient populations requires objective assessment.

Purpose of the Study:

  • To quantitatively assess the effect of a denture adhesive on the retention of complete mandibular dentures during chewing.
  • To evaluate the impact of denture adhesives on denture dislodgment in patients experiencing significant mandibular bone loss.

Main Methods:

  • Employed cineradiography to record mandibular denture movement during mastication in ten participants.

Related Experiment Videos

  • Participants were assessed with and without the application of a denture adhesive to the mandibular denture base.
  • Analyzed cineradiographic films to measure denture dislodgment, focusing on maximal and mean values.

    • Main Results:

    • A statistically significant reduction in maximal denture dislodgment was observed when using a denture adhesive.
    • The mean denture dislodgment also showed a decrease with adhesive use, although this change was not statistically significant.
    • Cineradiography provided objective data on denture stability under functional conditions.

    Conclusions:

    • Denture adhesives can significantly improve the maximal retention of complete mandibular dentures, particularly in patients with severe alveolar ridge resorption.
    • While mean dislodgment may decrease, the primary benefit lies in reducing the extent of extreme denture movement during chewing.
    • This study supports the use of denture adhesives as an adjunct to enhance functional stability and patient satisfaction with complete dentures.
