Features in subjects with the frontal occlusal plane inclined toward the contralateral side of the mandibular deviation

A patient with mandibular deviation and 3 mandibular incisors treated with asymmetrically bent improved superelastic nickel-titanium alloy wires

“…Dental compensation for mandibular deviation by buccolingual position and inclination of the mandibular first molars in the PA cephalometric radiograph in the intercuspal position has been reported. 20,29 A report of patients with an occlusal cant, inclined toward the ipsilateral side of the mandibular deviation, stated that the average of the inclinations of the mandibular first molars on the affected side and the nonaffected side with respect to the midline were 31.3 6 6.0 and 20.9 6 4.9 , respectively. 20 Although pretreatment inclinations of the mandibular first molar on the affected (left) and nonaffected (right) side were 25.0 and 27.0 in this patient, the inclinations at posttreatment were 26.5 and 17.5 (Fig 14).…”

The buccolingual position and the inclination of the teeth treated with the asymmetrically bent ISW may camouflage the mandibular deviation and 3 mandibular incisors.…”

“…The occlusal cant was inclined 2 upward to the left, and the mandible deviated by 3.0 mm to the left of the facial midline in the PA cephalometric analysis. 20 Based on these findings, we diagnosed the patient as skeletal Class II with an asymmetric molar relationship, mandibular deviation to the left, and 3 mandibular incisors.…”

Facial asymmetry – aetiology, classification and diagnostics based on the literature

“…na podstawie inklinacji płaszczyzny zgryzu (FOP -Frontal Occlusal Plane) i zbaczania bródki. Zauważyli oni morfologiczne i funkcjonalne różnice między ipsii kontrlateralnym typem asymetrii (42). Obu typom asymetrii towarzyszyła skośna płaszczyzna zgryzu, gdzie odległość od guzka mezjalnego policzkowego pierwszego stałego trzonowca szczęki do arbitralnej płaszczyzny poziomej jest różna po obu stronach (43).…”

“…Other two types of asymmetry have been classified by Uesugi et al on the basis of the inclination of the frontal occlusal plane (FOP) and the deviation of the chin. They noticed morphological and functional differences between the ipsi-and contralateral type of asymmetry (42). Both types of asymmetry were accompanied by occlusal plane canting, where the distance from the mesiobuccal cusp of the first permanent maxillary molar to the arbitrary horizontal plane is different on both sides (43).…”
