Stability of Class II malocclusion treatment with Class II elastics.

Introduction: The objective of this study was to compare the long-term cephalometric stability after successful therapy of nonextraction Class II malocclusion with elastics and with headgear.

Methods: The sample comprised 43 patients with Class II malocclusion and was divided into 2 groups. The elastic group (EG) consisted of 20 patients treated with fixed appliances associated with Class II elastics, and the headgear group (HG) consisted of 23 patients treated with fixed appliances and extraoral headgear.

Root resorption in Class II malocclusion treatment with and without maxillary premolar extractions.

Introduction: Class II malocclusion treatment efficiency with maxillary premolar extractions has been reported. However, no study evaluated the root resorption associated with this protocol. Therefore, this study aimed to compare the degree of root resorption of the maxillary incisors in Class II malocclusion treatment with and without maxillary premolar extractions.

Treatment Time of Class II Malocclusion, with and without Mandibular Crowding, Treated with Four Premolar Extractions: A Retrospective Study.

Objective: This study aimed to compare the treatment times in patients with complete bilateral Class II malocclusion, with and without mandibular crowding, treated with 4 premolar extractions.

Methods: The sample comprised 57 retrospectively and consecutively selected patients (30 male, 27 female) treated for initial Class II malocclusion, divided as follows: Group 1 consisted of 23 patients (11 males, 12 females; mean age 13.13 years) presenting no crowding or 3 mm at most.

Cephalometric radiographic comparison of alveolar bone height changes between adolescent and adult patients treated with premolar extractions: A retrospective study.

Objective: In orthodontic treatment, indication of dental extractions is very common and frequently used in adult patients. This situation is a recurrent concern among orthodontists, since age and extraction treatment are factors that may increase periodontal support loss. Therefore, this study aimed to evaluate adolescent and adult patients, orthodontically treated with maxillary premolar extractions, and compare both groups regarding the changes in alveolar bone height loss, retrospectively.

Changes in apical base sagittal relationship in Class II malocclusion treatment with and without premolar extractions: A systematic review and meta-analysis.

Objective: To evaluate the changes in apical base sagittal relationship in Class II treatment with and without premolar extractions.

Materials And Methods: Controlled studies evaluating ANB angle changes after Class II Division 1 malocclusion treatment with or without premolar extractions were considered. Electronic databases (PubMed, Embase, Web of Science, Scopus, The Cochrane Library, Lilacs, and Google Scholar) without limitations regarding publication year or language were searched.

Root resorption in Class II malocclusion treatment with Class II elastics.

Introduction: The objective of this investigation was to compare the amount of apical root resorption in nonextraction treatment of Class II malocclusions with and without Class II elastics.

Methods: A sample of 54 patients with Class II Division 1 malocclusion, retrospectively selected, was divided into 2 groups. The elastic group consisted of 27 patients who were exclusively treated with fixed appliances associated with elastics, and the headgear group consisted of 27 patients treated with fixed appliances and extraoral headgear.
