Impression materials and techniques used for cast restorations in eight states
Summary
Polysulfide is the most common impression material for dental cast restorations, preferred by over a third of dentists surveyed. Epinephrine cord is also the leading choice for gingival retraction among responding dental professionals.
Area of Science:
- Dental materials science
- Restorative dentistry
Background:
- Impression materials are crucial for accurate dental restorations.
- Gingival retraction techniques are essential for effective impression taking.
Purpose of the Study:
- To investigate the current usage patterns of impression materials for cast restorations among dentists.
- To determine the preferred methods for gingival retraction in dental practice.
Main Methods:
- A survey was conducted among dentists across eight U.S. states.
- Respondents reported their choices for impression materials and gingival retraction cords.
Main Results:
- Polysulfide was the most frequently used impression material for cast restorations (35.8%).
- Polyether and hydrocolloid were the second most utilized materials.
- Epinephrine cord was the preferred gingival retraction method (73.3%), followed by nonepinephrine cord (23.5%).
Conclusions:
- Polysulfide remains a dominant material for dental cast restorations.
- Epinephrine cord is the predominant choice for gingival retraction in surveyed dental practices.
