Composite resin restorations of large class II cavities using split-increment horizontal placement technique

Area of Science:

• Dentistry
• Dental Materials

Background:

• Restoring large Class II cavities with composite resin presents challenges.
• Polymerization shrinkage can lead to stress at the adhesive interface and compromise marginal integrity.

Purpose of the Study:

• To present a simplified technique for composite resin placement in large Class II cavities.
• To evaluate the technique's ability to manage polymerization shrinkage stresses and improve marginal seal.

Main Methods:

• Utilized a split-increment horizontal placement strategy for composite resin.
• Incorporated shade or chroma stratification during placement.
• Focused on restoring large Class II cavities.

Main Results:

• The technique effectively relieves polymerization shrinkage stresses at the adhesive interface.
• An improved marginal seal, particularly at the gingival margin, was observed.
• The method offers a simplified approach to posterior composite restorations.

Conclusions:

• The split-increment horizontal placement with stratification is a simplified, effective technique for large Class II composite restorations.
• This method enhances marginal seal and reduces stress, contributing to long-term clinical success.
• Clinicians can utilize this technique for high-quality posterior composite restorations.
