Thirty\u2010six records (22 females and 14 males; mean age, 17.4\u2009years) were divided into two groups: TAD (21 subjects with 25 edentulous spaces) and FFA (15 subjects with 24 edentulous spaces). The primary outcome measure was the efficiency of protraction [magnitude and time required for protraction (rate) and anchor loss (AL)]. The secondary outcomes involved measuring the type of tooth movement (TOTM), external apical root resorption (EARR), alveolar bone height change (ABHC), alveolar bone width change (ABWC) and appliance failure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The rate of tooth movement was significantly higher for FFAs (0.83\u2009\u00b1\u20090.35\u2009mm\/month) versus TADs (0.49\u2009\u00b1\u20090.2\u2009mm\/month) (<jats:italic>P<\/jats:italic>\u2009=\u2009.005). Total treatment duration was less for FFAs (34.78\u2009\u00b1\u20098.1\u2009months) versus TADs (47.72\u2009\u00b1\u200913.94\u2009months) (<jats:italic>P<\/jats:italic>\u2009=\u2009.002). TOTM was similar for both (<jats:italic>P<\/jats:italic>\u2009=\u2009.909). EARR was 1.42\u2009\u00b1\u20091.38\u2009mm for TAD and 1.25\u2009\u00b1\u20090.88\u2009mm for FFA (<jats:italic>P<\/jats:italic>\u2009=\u2009.81). ABHC increased in the FFA group (1.01\u2009\u00b1\u20093.62\u2009mm) and decreased for the TAD group (0.68\u2009\u00b1\u20091.66\u2009mm).
