A hybrid matrix retainer for two-surface proximal restorations

Area of Science:

• Dental Materials Science
• Restorative Dentistry

Background:

• Traditional matrix bands present challenges in achieving optimal contour and adaptation for proximal restorations.
• The need for improved handling and anatomical accuracy in dental restorative procedures is ongoing.

Purpose of the Study:

• To introduce and evaluate a novel hybrid matrix band designed for enhanced restoration of proximal tooth surfaces.
• To combine the beneficial properties of rigidity and flexibility in a single matrix system.

Main Methods:

• Development of a hybrid matrix band incorporating two distinct thicknesses.
• Application of the hybrid matrix band in simulated or clinical restorative procedures on proximal tooth surfaces.

Main Results:

• The hybrid matrix band demonstrated a combination of rigidity for stability and flexibility for adaptation.
• Improved contouring and marginal integrity of proximal restorations were observed.

Conclusions:

• The hybrid matrix band offers a promising advancement in restorative dentistry.
• This design facilitates more accurate and efficient restoration of proximal tooth surfaces.
