Steps for an Endocrown Procedure
The steps for an Endocrown procedure are not explicitly outlined in the provided studies. However, based on the information available, the following general steps can be inferred:
- Preparation of the tooth: This involves removing any decay or damaged tooth structure and shaping the tooth to receive the Endocrown 1, 2.
- Creation of a circular butt-joint margin and a central retention cavity inside the pulp chamber: This is a key feature of the Endocrown design, which provides macromechanical retention and microretention through adhesive cementation 1, 2.
- Use of a composite resin base: This may be used to fill undercuts and ensure a correct design of the preparations, contributing to significant tissue preservation 1.
- Fabrication of the Endocrown: This can be done using various materials, such as pressed ceramics or CAD/CAM techniques 1, 3.
- Cementation of the Endocrown: This involves bonding the Endocrown to the tooth structure using an adhesive cement 2.
Key Considerations
When performing an Endocrown procedure, the following considerations are important:
- The amount of remaining coronal substance: This will dictate the decision to omit a post and the design of the preparation 1.
- The presence of minimal interocclusal space and curved or narrow root canals: Endocrowns are strongly indicated in such cases 2.
- The use of materials that can be bonded to the tooth structure: This is essential for the success of the Endocrown restoration 2.
- The need for a supragingival position of the restoration margins: This helps to prevent interference with periodontal tissues and ensures self-cleansability 1, 3.
