Management of apico-marginal defects with endodontic microsurgery and guided tissue regeneration: a report of thirteen cases

The loss of periodontal tissue support and vertical buccal bone loss in apico-marginal defects can often be mistaken for features indicative of vertical root fractures and this study reports thirteen cases with persistent symptomatic apical periodontitis, apico-marginal defects, and large periapical lesions that were managed with endodontic microsurgery in conjunction with bone grafts and barrier placements with a follow-up period of up to 9 years. At the recall sessions, all cases were asymptomatic with radiographical success with only two cases exhibiting residual apical radiolucency, but with evident reduction in the lesion size, indicative of healing.
