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.
Expansion was completed when the palatal cusp of the maxillary first molars touched buccal cusp
of the mandibular first molars (14 days after the onset of expansion, on average).
The mesowear-I method is based on two major attributes named buccal cusp
shape (either the paracone or metacone) and cusp relief developed by attrition and abrasion for estimating average life long diet of ungulates (Kaiser and Solounias 2003; Franz-Odendaal and Solounias 2004).
There is no contact between the mandibular buccal cusp
and palatal maxillary cusps which might result in an inclined (non-axial) contact.
To obtain sufficient reproducibility of the molar alignment in the images, the teeth did not overlap each other interproximally, and the buccal cusp
tip of each molar was superimposed on the corresponding lingual cusp tip.
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.
Look over casts--notice how the bicuspids and molars have elongated--even the mesio buccal cusp
of the upper six year molar has tipped occlusally.
18 This is in contrast to prosthetic dentistry where the curve begins from cusp tip of mandibular canine and follows the buccal cusp
tips of posterior teeth.
palatal cusp of maxillary teeth and buccal cusp
of mandibular teeth) and sometimes palatal incline of maxillary buccal cusp
& buccal incline of lingual cusp.
In order to obtain sufficient reproducibility of the molar alignment on the image, the teeth should not overlap each other interproximally, and the buccal cusp
tip of each molar should be superimposed on the corresponding lingual cusp tip.
Two cusps type premolar has one large and functional buccal cusp
where as lingual cusp is very small and usually blunt.
Inter first premolar width was measured as transverse distance between the buccal cusp
tips of the first permanent premolars in both upper and lower dental arches.
