Healing response of apicomarginal defects to two guided tissue regeneration techniques in periradicular surgery: a double‐blind, randomized‐clinical trial

Abstract

Guided tissue regeneration applied to apicomarginal defects using sliding periosteal grafts and use of bioabsorbable membranes led to similar enhancements of the clinical outcome of periradicular surgery in terms of periapical healing, gain of periodontal support, PD reduction and minimal recession of the gingival margin.
