Summary
Bis-acryl composite resin provisional restorations demonstrated superior quality compared to PMMA materials. This study highlights bis-acryl as a better choice for dental provisional crowns.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Restorative Dentistry
Background:
- Traditional provisional crowns often exhibit issues with occlusion, contour, fit, and finish.
- Efficient and reliable fabrication methods are crucial for dental provisional restorations.
Purpose of the Study:
- To compare the quality of provisional restorations made from bis-acryl composite resin and PMMA by dental students.
- To identify the advantages and disadvantages of each material for provisional crown fabrication.
Main Methods:
- Evaluated 222 provisional crowns fabricated by dental students using bis-acryl composite resin (Integrity) and PMMA resins (C&B Resin, Snap).
- Assessed occlusion, contour, marginal adaptation, and finish of the provisional restorations.
Main Results:
- Bis-acryl composite resin (Integrity) was statistically superior to PMMA (C&B Resin and Snap) in most evaluated categories.
- Integrity showed significant advantages in anterior provisional crowns and for posterior crowns' contour and marginal adaptation.
Conclusions:
- Bis-acryl composite resin (Integrity) is a significantly superior material for provisional restorative applications compared to PMMA.
- The findings support the use of bis-acryl composite resins for improved quality in dental provisional crowns.
