26. Mai 2024 · A dental term for a stage of development when the upper incisors are tipped laterally and a midline space appears. It occurs before the permanent canines erupt and usually lasts until the age of 7 to 12 years.
5. März 2020 · Ebenfalls kann das Vorhandensein eines "ugly duckling stage" (Broadbent-Phänomen [7]) einen Hinweis auf Verlagerungen und Platzmangel geben. Dabei kippen die Schneidezähne als Folge der engen Keimlage der Eckzähne nach distal, und ein Diastema mediale entsteht.

Ugly duckling Stage (Fig 4) a self-correcting malocclusion is seen in the maxillary incisor region between 8-9 years of age. This situation is seen during the eruption of the permanent canines. This condition has been described by Broadbent as the ugly duckling stage as children tend to look ugly during this phase of development. This condition ...

6 weeks of gestation: development of the deciduous dentition begins.6 months: first deciduous teeth, mandibular central incisors, erupt.2½ years: all 20 deciduous teeth have erupted.Root development of deciduous dentition is completed within 12–18 months after their eruption to oral cavity.In the newborn maxilla, the horseshoe-shaped gum pad surrounds the shallow palate and overlaps the U-shaped mandibular gum pad. The future positions of the developing teeth can be seen on the gum pads as small segmented elevations separated by small transverse grooves (Fig. 1.3). One of these grooves, the ‘lateral sulcus’, is prominent, extending v...
The first deciduous teeth erupt around the same time as the infant adapts to a more complex swallowing pattern and is physiologically ready for weaning . Teething can be a big event in the infant’s life, as their eruption can cause multiple relatively minor symptoms such as general irritability, disturbed sleep, an increase in body temperature, dro...
From birth to 2 years of age, the intercanine width increases around 3.5 mm in the mandible and 5 mm in the maxilla . Subsequently, even the primary incisors might erupt in crowded positions, transverse growth ideally results in spacing in the labial segments providing additional space for the wider permanent incisors to erupt. In addition to gener...

1. Jan. 2015 · Learn about the calcification and eruption dates of the primary and permanent dentition, and the stages of tooth development. The ugly duckling stage is when the maxillary lateral incisors are distally splayed and there is a midline diastema.
The ugly duckling stage is a physiological stage characterized by a small median diastema and distally inclined incisors. A mesiodens is a supernumerary tooth found in the premaxilla between the two central incisors. It can be single or multiple, impacted, erupted, or inverted.
