Primary Stability of Temporary Screws after Dentary and Orthopedic Forces under Static and Dynamic Load Cycles

“…Similar method was previously disclosed in the preliminary experimentations of this work published in a pilot study [19].…”

“…Even though a low-density bone source was selected, a pilot hole 1 mm in diameter was to prevent any kind of crack formation in the cortical shell [19,[31][32][33][34].Authors decided to perform pilot holes to prevent the propagation of cracks, which would be intensified by the different load protocols proposed in this work.…”

“…The relevance of this simulation is coherent with intermaxillary biomechanics, when a huge block of teeth, or even an entire jaw, is desired to be moved. Examples of these biomechanics were presented in [27,35] and this method was preliminary tested in the pilot study of this work [19]. Currently available appliances involve the use of several springs, which can be accessible on [19,36,37].…”

“…All screws had the same taper design and dimensions: 6 mm long and 1.5 mm at maximum diameter ( Figure 1). Sample size calculations, details of bone blocks preparation and statistical comparisons were all detailed in the pilot study published as [19].…”

“…The advantages of temporary screws for dentary demand is presented in [11][12][13][14][15][16][17][18][19][20]. When tooth movements are desired, screws allow immediate possibility for biomechanical forces applications, which include even pull back of more than 10 teeth at once [21].…”
