The laterally closed tunnel (LCT) technique offers a minimally invasive approach for root coverage. This pilot study compared the effectiveness of LCT with chorion membrane (CM) allograft and subepithelial connective tissue graft (CTG) in isolated mandibular Miller\u2019s Class I, II, and III recessions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>Six healthy patients with isolated mandibular recession defects \u22653 mm were treated with LCT combined with either CM (test group) or CTG (control group).

At 12 months, CRC was achieved in 4 of 6 defects (75%), including 3 in the control group and 1 in the test group. The remaining defects exhibited 75% and 66% root coverage. Mean recession depth decreased from 4.00 mm to 0.00 mm in the control group and from 3.67 mm to 0.67 mm in the test group. Keratinized gingival width increased similarly in both groups. Mean root coverage was 100% in the control group and 75% in the test group (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.193).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>LCT with CM appears to be a promising alternative to CTG for isolated mandibular recession treatment.
