RESUMO
Tests demonstrated that the degree of movement of the abutment tooth for a distal-extension base using three different clasp designs was a function of the location of loading. Thus, the null hypothesis, there is no significant difference in the degree of movement of the abutment tooth around the axis of rotation as a function of the position of loading, has been demonstrated to be invalid based on the data obtained in this investigation.

Ten mandibular first molars were hemisected and the root surface of each root was measured using stereophotogrammetry and computer analysis. In each tooth the mesial root was determined to have a greater surface area than the distal root. This difference was statistically significant. The fact that the mesial root has the larger surface area must be a consideration when hemisection is planned.
