The Alveolar Ridge Splitting Technique on Maxillae: A Biomechanical Human Cadaveric Investigation

Table 1

Measured alveolar widths of all prepared specimens (crestal-buccal, crestal-oral, crestal-total, basal-buccal, basal-oral, and basal-total) together with the outcomes from their biomechanical testing (stiffness, failure force, and failure displacement).
