Fig. 6

Horizontal positions of the 23 right-side and 27 left-side lower third molars. Their minimum and maximum medio-lateral (x-axis) and antero-posterior (y-axis) distances are depicted two-dimensionally from the reference planes (levels 0), the sagittal plane set according to the lingual prominence point and the frontal plane according to the distal prominence point of the lower second-molar crown. The circles illustrate the optimized diameter and horizontal positioning of vertical cylinders that fully encompass these lower third molars and the MC. Continuous line—teeth without pathological findings. Dashed line—teeth with pathological findings
