Fabrication of an amalgam core using a customized acrylic resin shell

Area of Science:

• Restorative Dentistry
• Prosthodontics
• Dental Materials

Background:

• Endodontically treated molars often require restorative procedures.
• Restoring these teeth for fixed partial denture (FPD) abutments presents unique challenges.
• Achieving a stable core foundation and ideal preparation is crucial for FPD success.

Purpose of the Study:

• To describe a novel build-up technique using a customized acrylic resin shell.
• To evaluate the technique's efficacy in restoring endodontically treated molars for FPD design.
• To ensure proper core foundation and ideal tooth preparation for predictable outcomes.

Main Methods:

• A customized acrylic resin shell was fabricated.
• The shell was utilized to confine amalgam during the core build-up procedure.
• The technique was applied to endodontically treated molars designated for three-unit FPDs.

Main Results:

• The acrylic resin shell effectively confined the restorative material (amalgam).
• The technique prevented impingement on the surrounding periodontium.
• It facilitated the creation of a proper core foundation and ideal tooth preparation.

Conclusions:

• The described build-up technique offers a predictable method for restoring endodontically treated molars in FPD cases.
• The use of a customized acrylic resin shell enhances the stability and accuracy of the core foundation.
• This approach contributes to improved outcomes in complex dental restorations.
