The inclination of mandibular incisors revisited

Abstract

Lower incisor inclination is linked to the subject's sex, age, and skeletal pattern. It is not associated with symphyseal dimensions, except symphyseal depth. Factors related to natural inclination of lower incisors should be respected when establishing a treatment plan.

Sınıf I maloklüzyona sahip bireylerde çekimsiz sabit ortodontik tedavinin mandibular simfiz boyutları üzerine etkisinin değerlendirilmesi

“…Literatürde, alt kesici diş pozisyonu ile mandibular simfiz arasındaki ilişkiyi ve bu ilişkiyi etkileyen vertikal büyüme yönü, 7,8 alt çene gelişim fazlalığı, 9,14 ve yaş 10,15 gibi faktörleri inceleyen çalışmalar mevcuttur. Çalış-mamızın materyali, vertikal büyüme modeli normal olan bireylerden oluşturuldu.…”

Age- and gender-related incisor changes in different vertical craniofacial relationships

“…Multiple extraoral and intraoral forces and factors could impact their inclination and position. [1] At the same time, their position and inclination show a direct and indirect impact on the upper and lower lip positions. [23] They also play a major role in the rest and dynamic smile esthetics.…”

“…[111] Long-face facial pattern showed more proclined and extruded lower incisors than short-face facial pattern. [11] It was also found to be significantly correlated with gender, age,[1] and symphyseal depth.…”

“…[111] Long-face facial pattern showed more proclined and extruded lower incisors than short-face facial pattern. [11] It was also found to be significantly correlated with gender, age,[1] and symphyseal depth. [112] Lower incisors were also found to be more extruded in Class III subjects with negative overjet as compared to Class I subjects.…”

“…[11] It was also found to be significantly correlated with gender, age,[1] and symphyseal depth. [112] Lower incisors were also found to be more extruded in Class III subjects with negative overjet as compared to Class I subjects. [11] However, no significant association was reported between changes in lower incisor inclination and point B position as assessed on cephalometric radiographs.…”
