Summary
Fluid wax and polysulfide rubber showed no statistical difference in complete denture adjustments over one year. This suggests wax is a viable alternative for dental impressions, challenging previous assumptions.
Area of Science:
- Dentistry
- Prosthodontics
- Dental Materials Science
Background:
- Contrasting views exist on the suitability of wax for complete denture impressions.
- Some research suggests wax offers advantages over elastomeric materials.
Purpose of the Study:
- To compare the clinical performance of fluid wax versus light-body polysulfide rubber for complete denture impressions.
- To evaluate the number of adjustments required for dentures fabricated with each impression material.
Main Methods:
- Fifteen complete dentures were fabricated using fluid wax for final impressions.
- Another fifteen complete dentures were fabricated using light-body polysulfide rubber.
- The number of post-insertion adjustments was recorded over a one-year period for all dentures.
Main Results:
- No statistically significant difference was found in the number of adjustments required between the fluid wax group and the polysulfide rubber group.
- This indicates comparable clinical outcomes for both impression materials in complete denture fabrication.
Conclusions:
- Fluid wax is a clinically acceptable material for making impressions for complete dentures.
- The findings challenge the notion that wax is unsuitable for complete denture impressions, supporting its use as an alternative to elastomeric materials.
