Pressure indicators for removable prosthodontics

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.
