Summary
Two impression techniques for edentulous patients showed no significant differences in reproducing maxillary tissue form. The second method, using tissue treatment material and light-body polysulfide, is recommended for patient convenience and clinician efficiency.
Area of Science:
- Dentistry
- Prosthodontics
- Dental Materials
Background:
- Accurate reproduction of maxillary tissue form is crucial for complete denture fabrication in edentulous patients.
- Conventional impression techniques can be time-consuming and may cause patient discomfort.
Purpose of the Study:
- To compare the efficacy of two distinct impression procedures for capturing the maxillary tissue form in edentulous patients.
- To evaluate patient comfort and clinician efficiency associated with each technique.
Main Methods:
- Two impression procedures were evaluated in five edentulous patients, each repeated thrice.
- Procedure 1: Modeling plastic for border molding with regular-body polysulfide for tissue contour.
- Procedure 2: Tissue treatment material for border molding with light-body polysulfide for tissue contour.
Main Results:
- No statistically significant differences were observed in the casts' profiles between the two procedures.
- Peripheral tissues were easily displaced with minimal manipulation using both methods.
- The second procedure demonstrated superior patient convenience and time efficiency for the clinician.
Conclusions:
- Both impression techniques effectively reproduce maxillary tissue form in edentulous patients.
- The second procedure offers advantages in terms of patient comfort and clinical efficiency, making it a recommended option.
