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.
A healthy occlusion should result in small areas of contact on cusp tips
or in occlusal fossae.
The depth of curve of Spee was measured as the perpendicular distance between the deepest cusp tip
and a flat plane that was laid on the occlusal surface of the mandibular dental cast.
Arch width was measured as the distance from the cusp tip
of one tooth to the cusp tip
of the contralateral tooth, the inter-incisor width was measured from the distal contact point of the lateral incisor on one side to the distal contact point of the lateral incisor on the contralateral side [Bishara et al.
It is the measured distance between the right and left first molars distobuccal cusp tips
On lateral cephalograms, perpendicular distances from the incisal tip of mandibular central incisor (L1-MP), the deepest point of COS (S-MP) and distobuccal cusp tip
of mandibular second molar (L7-MP) to mandibualr plane (MP) were measured and proportioned as L1-MP/S-MP and L7-MP/S-MP.
The mesiodistal extension of the cavity on mesial and distal boxes of all prepared teeth was up to 1 mm to adjacent cusp tips
The depth of the Curve of Spee was measured on lateral cephalograms as perpendicular distance from incisal tip of the mandibular central incisor to the mandibular plane (L1-MP), distobuccal cusp tip
of the mandibular second molar (M7-MP) to the mandibular plane, the deepest point of the Curve of Spee to the mandibular plane (S-MP), and proportioned with each other.
Maxillary Interpremolar width (UP-P): Distance be- tween buccal cusp tips
of right and left maxillary first premolars.
Maxillary Interpremolar width (UP-P): Distance between buccal cusp tips
of right and left maxillary permanent first premolars.
The vernier caliper was used to measure the distance between the mesiobuccal cusp tips
of mandibular first molars.
Intercanine width (ICW) The distance between cusp tips
He drew a straight line between two points on the cusp tips
of the teeth adjacent to the extraction site.
Vernier caliper was used to measure the distance between the cusp tips
of maxillary canines.
Currier defined three curves, an outer curve based on cusp tips
and incisor edges, a middle curve based on fossae and fissures and cingulae and an inner curve based on inner aspects of teeth.
