title: Membrane exposure during bone regeneration before implant placement: management and results. A report of two cases.
abstract: Two patients with apical lesions on maxillary central incisors showed large osseous defects of the residual ridge. E-PTFE membranes were used for ridge reconstruction, which allowed for the placement of implants of appropriate diameters. In the two cases described, the membranes were exposed and replaced. This technique facilitated atrophic ridge reconstruction in spite of premature membrane exposure.
