Summary
Digital impressions are preferred over conventional methods for implant-supported fixed prostheses. They offer faster impression times and shorter adjustment durations, leading to improved patient satisfaction.
Area of Science:
- Dental materials science
- Prosthodontics
- Digital dentistry
Background:
- Conventional impressions are time-consuming and can be uncomfortable for patients.
- Digital impressions offer a potentially more efficient and patient-friendly alternative in prosthodontics.
Purpose of the Study:
- To compare conventional and digital impressions for implant-supported fixed prostheses.
- To evaluate accuracy, time efficiency, and patient preference between the two impression methods.
Main Methods:
- Systematic review adhering to PRISMA guidelines, registered in PROSPERO.
- Searched multiple databases (PubMed, Scopus, Embase, Web of Science, ProQuest) up to September 2023.
- Included 27 studies with 737 patients; assessed risk of bias and performed meta-analysis.
Main Results:
- Both methods yielded similar prosthetic results and accuracy.
- Digital impressions demonstrated significantly shorter scanning and adjustment times.
- Meta-analysis confirmed a strong patient preference for digital impressions.
Conclusions:
- Intraoral scanning (digital impressions) offers superior patient perception.
- Digital impressions are more time-efficient for both the impression and adjustment phases.
- This technology enhances the overall patient experience in fixed prosthodontics.
