Clear matrix use for composite resin core fabrication.

Area of Science:

• Restorative Dentistry
• Dental Materials

Background:

• Endodontically treated teeth often suffer significant coronal and radicular dentin loss.
• Preserving remaining tooth structure is vital for successful restorative treatment prognosis.
• Accurate core dimensions (height and width) are essential for final restoration fit.

Observation:

• Direct free-hand composite resin core buildup can be challenging and time-consuming.
• A clinical technique utilizing a clear matrix for composite resin injection was developed.

Findings:

• The clear matrix technique facilitates composite resin injection.
• This method allows for the creation of an ideal post and core shape and size.

Implications:

• This technique offers a potentially more efficient and predictable method for post and core fabrication.
• Improved core fabrication can enhance the longevity of restorations on endodontically treated teeth.
