Area of Science:
- Dental materials science
- Prosthodontics
- Digital dentistry
Background:
- Definitive impression accuracy is crucial for final prosthesis quality.
- Conventional impressions use elastic materials for replicating anatomy.
- Digital impressions offer advantages like 3D previsualization and efficiency.
Purpose of the Study:
- To compare digital impression techniques with conventional methods.
- To evaluate accuracy, patient acceptability, and operator preference.
- To assess time effectiveness of digital versus conventional impressions.
Main Methods:
- Systematic literature review (2000-2023) using the PICO framework.
- Searched PubMed, Medline, Cochrane, and Web of Science databases.
- Included clinical, preclinical, and randomized controlled trials.
Main Results:
- Digital impressions demonstrate accuracy comparable to conventional impressions.
- No statistically significant differences were found in accuracy.
- Patient and operator preferences were also evaluated.
Conclusions:
- Digital impressions are a viable alternative to conventional methods.
- Accuracy is not compromised with digital impression techniques.
- Digital dentistry offers comparable outcomes with potential efficiency gains.
