Metal endocrown approach for a maxillary second molar: a novel technique

Area of Science:

• Restorative Dentistry
• Dental Materials Science

Background:

• Nonvital teeth often present complex restorative challenges, especially when previous treatments fail.
• Repeated failures necessitate innovative approaches to preserve tooth structure and function.

Purpose of the Study:

• To describe the fabrication of a novel cast metal endocrown for a nonvital tooth with a history of multiple restoration failures.
• To evaluate the potential of this conservative approach in avoiding tooth extraction.

Main Methods:

• A case report detailing the step-by-step fabrication of a cast metal endocrown.
• The endocrown was designed to fit passively within the prepared pulp chamber and coronal dentin.
• Clinical and radiographic follow-up assessments were performed.

Main Results:

• The cast metal endocrown fabrication was successfully completed.
• The endocrown provided a stable and functional restoration.
• The treated tooth was preserved, avoiding extraction.

Conclusions:

• A novel cast metal endocrown can be a successful treatment option for nonvital teeth with recurrent restoration failures.
• This technique offers a conservative alternative to extraction, preserving natural tooth structure.
