“…Two studies employed the minimally invasive surgical technique [63, 66], seven used the modified minimally invasive surgical technique [13, 46, 51, 52, 59, 69, 70], and others used the simplified or modified papilla preservation flap. In terms of defect morphology, 14 involved 1‐ to 2‐wall intrabony defects [35, 36, 40, 42, 45, 47, 54, 56, 60, 62–64, 71, 81], one involved 2‐wall intrabony defects [53], four had 3‐wall intrabony defects [13, 67, 77, 84], five involved 2‐ to 3‐wall intrabony defects [14, 44, 50, 57, 73], 21 involved 1‐, 2‐, or 3‐wall intrabony defects [15, 20, 37, 43, 46, 48, 49, 51, 55, 58, 59, 61, 68, 69, 72, 74, 78–80, 82, 83, 85], and 12 did not provide sufficient details regarding the typology of defects [38, 39, 41, 52, 65, 66, 70, 75, 76, 86, 87].…”
