JONKER, CH  y  VAN DER VYVER, PJ. Apexification of immature teeth using an apical matrix and MTA barrier material: Report of two cases. S. Afr. dent. j. [online]. 2017, vol.72, n.9, pp.414-419. ISSN 0375-1562.  http://dx.doi.org/10.17159/2519-0105/2017/v72no9a3.

Apexification is defined as a method to induce a calcified barrier at the root tip of a tooth with an open apex or to encourage the continued apical development of an incomplete root in teeth with necrotic pulps. Two case reports are presented in which teeth with large open apices and immature roots were clinically managed by placing demineralised freeze-dried bone allograft (DFDBA) as a matrix before placement of Mineral Trioxide Aggregate (MTA) as an apical barrier. The indications for and advantages of using DFDBA and MTA are discussed.
