Table 1 The definitions of parameters and methods of measurements.
| Aspect and reference | Parameters (abbreviation) | Parameters definition, evaluation/Figure number |
|---|---|---|
| Sagittal aspect [,]9 | Incisive foramen (IF) | The labio-palatal diameter of IF, NPC’s oral opening’s diameter. The diameter of IF was determined by taking a mean of various canal measurements, assuming that the NPC had an anatomic two-parallel shape Figure 1A (1) |
| Stenson foramen (SF) | The diameter of SF, NPC’s nasal opening was measured. The diameter of SF was determined by taking a mean of various canal measurements, assuming that the NPC had an anatomic two-parallel or Y shape Figure 1A (2) | |
| Mid-level of NPC | The width of the NPC at its center Figure 1A (3) | |
| NPC length | The distance from SF to IF. The length of NPC was determined by taking a mean of various canal measurements, assuming that the canal had an anatomic parallel or Y shape Figure 1A (4) | |
| Buccal bone plate 1 (BBP1) | The horizontal diameter of BBP, the line between the alveolar bone’s anterior cortical layer, and the anterior extremity of IF Figure 1A (5) | |
| Buccal bone plate 2 (BBP2) | The horizontal diameter of a buccal bone plate, using a horizontal line drawn from the palatal border of the IF, the width is the distance between NPC’s buccal border and the buccal cortical layer of the alveolar process Figure 1A (6) | |
| Buccal bone plate 3 (BBP3) | The horizontal diameter of a buccal bone plate, the line at the middle of the NPC, from a buccal cortical layer of the alveolar process to the buccal border of NPC Figure 1A (7) | |
