title: Apexification with MTA using internal matrix: report of 2 cases.
abstract: Calcium hydroxide (CH) has been reported to have several drawbacks when used for apexification. Mineral Trioxide Aggregate (MTA) has generated considerable interest as an alternative. Two different cases are reported using MTA for apexification. In the first case an incomplete CH barrier was used as a matrix against which MTA could be condensed. In the second case internal matrix was formed using absorbable collagen sponge and a comparable result could be achieved. Further studies are needed to develop it into a standardized method, akin to that of matrices used in class II restoration.
