First Premolar Extraction Decisions and Effects
… (TSALD) is to treat patients with the extraction of premolars. Not all of the extraction space, however, is needed to eliminate the patient's TSALD. Also, it is typical that some of the extraction space will be lost because the molars are used as anchorage units to retract the anterior …

Oropharyngeal Airway Volume Following Orthodontic Treatment: Premolar Extraction Versus Non-Extraction
… methods of treatment. The first involves the extraction of teeth to gain the space needed for tooth alignment. The second relies on arch expansion to gain the space needed for correction. In recent decades, arguments for and against the extraction of teeth for orthodontic purposes have become …

Quantitative Analysis of First- versus Second-Premolar Extraction Effects in Orthodontic Treatment
… discrepancies that have to be resolved by premolar extractions. Treatment planning in such cases usually involves removing first (P1) or second premolars (P2). Choosing an extraction pattern is a learned skill that incorporates many diagnostic factors. This study compared the amounts of …

Premolar Extraction Cases Treated with Aligners: Are Contemporary Results Comparable to Fixed Appliances?
… Historically, it has been challenging to treat premolar extraction cases with aligners to the same occlusal standards as fixed appliances. The purpose of this study was to assess whether premolar extraction cases treated with Invisalign in the past 5 years have more comparable results to cases …

Cephalometric Evaluation of One-Phase and Two-Phase Treatment Alternatives in Matched Class Ii Subjects
… The two-phase subjects had a lower rate of premolar extraction (3% vs. 56%) than the one-phase subjects. Similar skeletodental endpoints were achieved regardless of treatment protocol; indicating the treatments can be viewed as equivalent approaches to a common problem.</p>

Morphological Changes in Alveolar Bone Following Orthodontic Space Closure
… orthodontic treatment with bilateral maxillary premolar extraction were evaluated. Only patients with at least 5 degrees of changes in maxillary incisor (U1) to palatal plane angle were included in the study. Before (T1) and after (T2) orthodontic treatment CBCTs were reconstructed with the …

Cephalometric Evaluation of Bionator Therapy in the Early Treatment of Class II Malocclusions
… The two-phase subjects had a lower rate of premolar extraction (12% vs 84%) than the one-phase subjects. Overall, the two-phase group achieved a better bony facial profile, with the majority of the skeletal and dental correction occurring during the first phase of treatment. These favorable …

Long-Term Changes in the Dental Occlusion of Subjects Treated Orthodontically
… relapse of mandibular anterior alignment-first premolar extraction cases treated by traditional edgewise orthodontics. Am J Orthod 1981;80:349-65). The present results exhibit less relapse than those reported in most long-term recall studies, which suggests that the extent of relapse may be less …
