What is a characteristic not associated with a normal smile?

Which of the following best describes the angle of a normal smile?

What is an indicator of a non-normal smile?

Which feature does not indicate a well-proportioned smile?

Space Creation

Derotation of posterior teeth creates space
Proclining incisors creates space
Retroclining incisors does not create space
Expansion creates space

Normal Smile Features

Upper incisors do not touch lower lip and run parallel to it
Width of smile displays at least upper first premolars
Whole of the upper incisor are showing with interproximal gingiva
Width of smile displays at least upper second Molar is NOT a feature of a normal smile

Spontaneous Movement

Spontaneous movement is greater in growing children
Spontaneous movement is less in adults
Spontaneous movement is increased when extractions are carried out prior to eruption of adjacent teeth
Spontaneous movement is increased if no occlusal interferences are present

Retained Deciduous Mandibular Incisors

Causes lingual eruption of permanent mandibular incisors

Space Analysis

Positive value indicates space deficiency
Space discrepancy is calculated from space available minus space needed
Negative value indicates excess space

Class I Malocclusion

In crowded Class I malocclusions, extractions in both arches are preferred to discourage the development of one arch more than the other
Expansion is not always the treatment of choice in crowded dentition
Fixed appliances are not always the treatment of choice in crowded dentition

Serial Extraction

Aims to intercept developing arch-length deficiency and reduce/eliminate extensive appliance therapy needs

Arch Length Discrepancies

The most likely malpositioned tooth in a mandibular arch length discrepancy is the 2nd premolar

Crowding Relief

Most spontaneous improvement occurs within the first 6 months after extractions

This quiz explores key concepts in orthodontics, focusing on space creation, normal smile characteristics, and the spontaneous movement of teeth. It will test your understanding of how tooth positioning affects dental aesthetics and treatment outcomes. Ideal for students and professionals in dental fields.
