Summary
Mineral trioxide aggregate (MTA) is effective for apexification, but controlling its placement in wide open apices is challenging. Using an internal matrix, like absorbable collagen sponge, provides a stable base for MTA, preventing extrusion into periodontal tissues.
Area of Science:
- Endodontics
- Regenerative dentistry
Background:
- Apexification aims to achieve root-end closure in immature teeth.
- Calcium hydroxide has been the traditional material for apexification.
- Mineral trioxide aggregate (MTA) offers an alternative for artificial root-end closure.
Observation:
- A significant challenge in apexification with wide open apices is controlling material placement.
- Extrusion of apexification material into the periodontal ligament space can occur.
- A matrix is recommended to contain the sealing material at the apex.
Findings:
- This case report details the use of an internal matrix made from absorbable collagen sponge.
- The collagen sponge served as a base for the placement of mineral trioxide aggregate (MTA).
- This technique effectively managed MTA placement in a wide open apex.
Implications:
- Employing an internal matrix like collagen sponge may improve the predictability of apexification procedures.
- This method could enhance the success rate of root-end closure with MTA.
- Further research into matrix-assisted apexification techniques is warranted.
