Soft-tissue changes in Class II malocclusion patients treated with extractions: a systematic review.

Background: Concerns about the effects caused by premolar extractions on the soft-tissue profile have motivated many investigations in different malocclusions.

Objectives: To evaluate the cephalometric facial soft-tissue changes after orthodontic treatment with premolar extractions of Class II division 1 malocclusion subjects.

Search Methods: Electronic databases PubMed, Web of Science, Embase, and Scopus were searched.

Influence of premolar extractions on long-term adult facial aesthetics and apparent age.

Objectives: This study aimed to assess whether non-extraction, two-premolars and four-premolars extraction Class II treatment protocols are different regarding long-term facial aesthetics, age appearance, and soft-tissue measures.

Methods: Frontal and lateral photographs of 63 full Class II division 1 patients, treated at least 8 years before, were evaluated by 83 laypeople and 76 orthodontists, who assigned to each one's attractiveness scores from 1 to 10, and opined about their apparent ages. Patients were divided in three groups: XP0 (non-extraction, n = 20; 30.

Comparison between full face and hemifacial CBCT cephalograms in clinically symmetrical patients: a pilot study.

Introduction: One of the advantages of cone-beam computed tomography (CBCT) is the possibility of obtaining images of conventional lateral cephalograms derived from partial or complete reconstruction of facial images.

Objective: This study aimed at comparing full face, right and left hemifacial CBCT cephalograms of orthodontic patients without clinical facial asymmetry.

Methods: The sample comprised nine clinically symmetrical patients who had pretreatment full face CBCT.
