    The P.I.P. pressure spot indicator accurately predicted denture pressure spots, reducing patient discomfort more effectively than the Coltene indicator. This clinical study highlights P.I.P.

    Area of Science:

    • Dentistry
    • Prosthodontics
    • Biomaterials

    Background:

    • Accurate denture fitting is crucial for patient comfort and function.
    • Identifying and relieving pressure spots post-delivery can be challenging.
    • Existing pressure spot indicators vary in clinical predictability.

    Purpose of the Study:

    • To compare the clinical efficacy of the P.I.P. (Pressure Indicating Paste) and Coltene pressure spot indicators.
    • To evaluate the correlation between predicted and actual denture pressure spots.
    • To assess the impact of each indicator on reducing post-delivery patient discomfort.

    Main Methods:

    • Thirty sets of complete dentures and two maxillary dentures against natural dentition were used.
    • Pressure spots were assessed at delivery and 24 hours post-delivery without initial adjustment.

  • Dentures were adjusted using either P.I.P. or Coltene, with patients recalled after one week.

    • Main Results:

    • The P.I.P. indicator demonstrated a higher clinical correlation between predicted and actual pressure spots.
    • Adjustments guided by P.I.P. resulted in fewer patients experiencing post-delivery discomfort.
    • The Coltene indicator showed a lower correlation and less predictable outcomes.

    Conclusions:

    • The P.I.P. pressure spot indicator offers superior clinical predictability for denture adjustments.
    • Utilizing P.I.P. can significantly improve patient comfort and reduce the need for follow-up adjustments.
    • P.I.P. is a more effective tool for prosthodontists in managing denture-related pressure points.
