Comparative evaluation of border molding using two different techniques in maxillary edentulous arches: A clinical...

Area of Science:

• Prosthodontics
• Dental Materials

Background:

• Denture retention is crucial for patient comfort and function.
• Accurate border molding techniques are essential for achieving optimal denture retention.

Purpose of the Study:

• To compare the retention of heat cure trial denture bases using single-step border molding with heavy viscosity silicone versus sectional border molding with low fusing impression compound.

Main Methods:

• An in vivo study involving ten completely edentulous patients.
• Comparison of single-step (Group 1) and sectional (Group 2) border molding techniques for denture retention.
• Definitive wash impressions utilized light viscosity addition silicone; results analyzed with a paired t-test.

Main Results:

• A statistically significant difference in retention was observed between the two groups (P = 0.014).
• The sectional border molding technique (Group 2) yielded significantly higher retention (mean = 9.05 kgf) than the single-step technique (Group 1, mean = 8.26 kgf).

Conclusions:

• The sectional border molding technique demonstrated superior retentiveness for denture bases compared to the single-step technique.
• Despite statistical significance, the clinical difference in retention between the methods was perceived as comparable.
