INTRODUCTION: Although Class II elastics have been widely used in the correction of Class
II malocclusions, there is still a belief that their side effects override the intended objectives …

A study of the literature reveals a variety of opinions on the potential for change in arch
dimensions. The variations in sample sizes, treatment mechanics, and retention regimens …

Dental casts of 30 patients treated with extraction and 30 patients without extraction of four
first premolars were randomly selected to determine changes in arch width as a result of …

This study compared the occlusal success rate of Class II orthodontic treatment results with
either 2-or 4-premolar extraction protocols. Group 1 comprised dental study models of 81 …

Objective: To compare the effects of extraction vs nonextraction orthodontic treatments on
oropharyngeal airway volume. Materials and Methods: An existing patient database was …

The aim of this retrospective study was to examine the dental arch width changes of
extraction and nonextraction treatment in Class I patients. The study was performed on …

The purpose of this study was to examine dimensional changes in the maxillary arch
following the extractions of maxillary first or second premolars. Pre-and posttreatment …

Introduction: In this study, we evaluated and compared treatment effects and long-term soft-
tissue profile changes in patients treated with extraction of 4 first premolars and with a …

The changes in the dental arch dimensions that occur as a result of growth and treatment
are of interest to the orthodontist and require careful consideration during treatment …

Introduction: In this study, we compared the efficiency of nonextraction and 2-maxillary-
premolar-extraction protocols in complete Class II malocclusion treatment. Methods: A …
