The included Overjet (OJ), which is the distance in millimeters (parallel to the occlusal plane) from the most labial aspect of the maxillary central incisor to the most labial aspect of the mandibular central incisor;9 overbite (OB), which is the percentage of the mandibular central incisors overlapped by the maxillary central incisors;9 mandibular inter-canine width, which is the distance in millimeters between cusp tips or estimated cusp tips in cases of wear facets if primary canines are present;9 canine length,
The original article was written in 1890 by Ferdinand Graff Spee, and it has been recently represented that this anteroposterior curve, or curve of Spee, was defined as the anatomical curve established by the occlusal alignment of the teeth, as projected onto the median plane, beginning with the cusp tip of the mandibular canine and following the buccal cusp tips of the premolar and molar teeth, continuing through the anterior border of the mandibular ramus, and ending at the anterior aspect of the mandibular condyle.
In clinical orthodontics curve of Spee refers to an occlusal curve of mandibular teeth running tangent from buccal cusp tips of posterior teeth to incisal edges of anterior teeth1,15.
The relative position of the IOF in relation to the upper teeth was recorded either as in line with the same vertical axis passing through the cusp tip of the upper canine, or buccal cusp tip of the upper first premolar, or second premolar, or mesiobuccal and distobuccal cusp tips of the first molar or as lying in the vertical axis passing between the canine and the first premolar or first and second premolar or second premolar and first molar (Figure 1).
1C), perhaps the hardest form of enamel hypoplasia to detect, manifests as an irregular sloping around the cusp tips of teeth.
Oblique stresses applied to the cuspal inclines, rather than cusp tips, put more stress on the tooth structure (Figure 2).
A vinyl sheet 1.1 mm thick was applied to the mesiobuccal cusp tips of right and left waxed mandibular first molars, and the articulator was closed.
The reference points and landmarks used were similar to those in previous studies [Bishara et al., 1997, Bishara et al., 1998, Franchi et al., 2006] and included; the contact point between adjacent teeth, cusp tips of the canines, buccal cusps of first and second premolars and mesiobuccal cusps of the first permanent molars.
The selected points were: the midincisal points of the incisors, the canine's cusp tips, the buccal cusp tips of the premolars, and the distobuccal cusp tips of the first molars (Fig.
The perpendicular distance from the buccal cusp tips of the involved teeth to the constructed line through the horizontal reference plane were measured and the deepest points of the VSC were calculated for the right and left sides.
