“…Until recently, our understanding of gender variations in craniofacial anatomy has been chiefly built upon anthropometric studies, which typically employ facial surface measurements or plain film radiography (Farkas and Kolar, 1987;Hurst et al, 2007). However, a common limitation to these studies is the inability to describe in detail the three dimensional anatomy of the frontal sinus and its anatomical relationship to the forehead.…”

“…Measurements are then generated to aid in determining the direction and extent to which structures or points need to be moved. 8,9 Today, cephalometrics is used for virtually all procedures that involve manipulation of the craniofacial skeleton.…”

“…Traditionally, the clinical tooth displacement was quantified by using two-dimensional (2D) cephalometric analysis, 3-7 which is incapable of detecting tooth displacement in the directions perpendicular to the sagittal plane. 3,8 Clinical 3D displacements can be calculated from digital models reconstructed from cone-beam computed tomography images 9 and digitized dental casts. 10-14 …”

Objective To validate whether applying a well-defined initial three-dimensional (3D) load can create consistently expected tooth movement in patients. Materials and Methods Twenty-one patients who needed bilateral canine retraction to close extraction space were selected for this split-mouth clinical trial. After initial alignment and leveling, two canines in each patient were randomly assigned to receive either translation (TR) or controlled tipping (CT) load. The load was delivered by segmental T-loops designed to give specific initial moment/force ratios to the canines in each treatment interval (TI), verified with an orthodontic force tester. Maxillary dental casts were made before canine retraction and after each TI. The casts were digitized with a 3D laser scanner. The digital models were superimposed on the palatal rugae region. The 3D canine displacements and the displacement patterns in terms of TR, CT, and torque were calculated for each TI. Results The method can reliably detect a TR displacement greater than 0.3 mm and a rotation greater than 1.5°. Ninety-two TIs had displacements that were greater than 0.3 mm and were used for further analysis. Most displacements were oriented within ±45° from the distal direction. The displacement pattern in terms of TR or CT was not uniquely controlled by the initial moment/force ratio. Conclusions The initial load system is not the only key factor controlling tooth movement. Using a segmental T-loop with a well-controlled load system, large variations in canine displacement can be expected clinically.
