The following values was measured: angle of cusp line between the second and third molar, impact state and depth, distance from Rickett's Xi to distal cusp of third mandibular molar along the occlusal plane, anterior border of ramus to the third mandibular molar, distance from projection of distal contact point of maxillary third molar to intersection of pterygoid vertical on occlusal plane.The change between pre-and post-treatment was calculated and analyzed with SPSS10.0 software package.α angle, Xi-LTM, R-LTM, R-LTM were tested with independent-sample t test, impact state and depth was tested with Chi-square test. Influence of age on the values was also evaluated.

Firstly, the developing principles of the cylindrical internal helical gear are proposed through analyzing the movement and geometry requirements, which provides continuous contact between the mating gear surfaces. The tooth surface of the internal helical gear in the new gearing can be imagined as being generated by the normal section of the conjugated surface of the ball-tooth, moving along the radial projection of helix line of the tooth-root circle. Also, the proposed surface can be approximate tangent to the conjugated surface of the ball-tooth along a spacial curve.
