Introduction: Dental expansion is used to correct transverse discrepancies such as constriction of the maxilla or a posterior crossbite. Rapid maxillary expansion (RME) corrects the constriction of the maxilla by opening the skeletal sutures of the maxilla along with tipping and moving teeth. This standard treatment for the correction of transverse maxillary deficiency applies forces to the maxilla through the anchor teeth which can result in unfavorable changes to anchor tooth angulation and the buccal bone adjacent to these teeth. Objectives: The aim of this study was to compare changes in buccal bone width and height and intermolar inclination in adolescent patients pre and post rapid maxillary expansion and investigate the correlation of these factors with skeletal maturation using cervical vertebral maturation stages (CVM) and mid-palatal suture density ratio (MPSD) at the start of treatment. Methods: This study was conducted on cone beam computed tomography (CBCT) images of 25 patients, pre-, and post expansion. CVMS and MPSD were from the pre-treatment CBCT. Buccal bone thickness, buccal bone height and intermolar inclination were calculated pre-, and post expansion. The correlation between changes in alveolar bone variables and skeletal maturity using CVM and MPSD was investigated. Results: No statistically significant relationship was found between MPSD and changes in bone variables. Further, no statistically significant relationship was found between CVM stage and changes in bone variables. There were no statistically significant correlations; therefore we failed to reject the null hypothesis. Conclusion: There is no relationship between changes in alveolar bone variables around molar teeth following RME and pre-treatment CVM and MPSD.

The purpose of this study was to use cone-beam computed tomography (CBCT) to assess changes in the volume and cross sectional areas of the upper airway in children with maxillary constriction treated by rapid maxillary expansion (RME). The study group consisted of 5 males and 9 females with mean age of 12.93 years with posterior cross bite and constricted maxilla who were treated with hyrax expander as part of their comprehensive orthodontic treatment. Pre and post RME CBCT scans were analyzed with 3D Dolphin 11.0 software to measure the retropalatal (RP) and retroglossal (RG) airway changes including volume and cross sectional areas. The transverse width changes were evaluated from the maxillary inter 1st molar and inter 1st pre molar mid lingual alveolar plate points. Pre and post RME scans were compared with paired t test and Pearson correlation test was done on data reaching significance. Only the cross sectional airway measured at posterior nasal spine (PNS) to Basion (Ba) level showed a statistically significant increase (P=0.0004). The minimal cross sectional area (MCA) was always found within the RP airway. The inter-molar and inter-premolar mid lingual alveolar plate distances increased equally by 4.76 mm and were statistically significant (P

Provides the latest information on all aspects of using temporary anchorage devices in clinical orthodontics, from diagnosis and treatment planning to appliances and applications Written by some of the world’s leading experts in orthodontics, Temporary Anchorage Devices in Clinical Orthodontics is a comprehensive, up-to-date reference that covers all aspects of temporary anchorage device (TAD) use in contemporary orthodontics. Taking a real-world approach to the subject, it covers topics ranging from diagnosis and treatment planning to the many applications and management of complications. Case studies demonstrate the concepts, and high-quality clinical photographs support the text throughout. The book begins with an overview of clinical applications and fundamental principles of TADs. It then goes on to cover biomechanical considerations for controlling target tooth movement with TADs. Biomechanical simulations for various clinical scenarios treated with TADs are addressed next, followed by an examination of histological aspects during the healing process and anatomical considerations with TADs. Other chapters cover: Class II Correction with TADs, Distalization with TADs, TAD-anchored Maxillary Protraction, Maxillary Expansion with TADs, Anterior Open Bite Correction with TADs, TAD-assisted Aligner Therapy, TADs vs. Orthognathic Surgery; Legal Considerations When Using TADs; and much more. Provides evidence-based information on the use of TADs, with a focus on improving outcomes for patients Considers topics ranging from diagnosis and treatment planning to specific clinical applications and appliances Takes a real-world clinical approach, with case studies demonstrating concepts Written by international experts in the field Presents hundreds of high-quality clinical photographs to support the text Temporary Anchorage Devices in Clinical Orthodontics is an essential resource for orthodontists and orthodontic residents.

Since its introduction to dentistry, cone beam computed tomography (CBCT) has undergone a rapid evolution and considerable integration into orthodontics. However, despite the increasing popularity of CBCT and progress in applying it to clinical orthodontics, the profession has lacked a cohesive, comprehensive and objective reference that provides clinicians with the background needed to utilize this technology optimally for treating their patients. Cone Beam Computed Tomography in Orthodontics provides timely, impartial, and state-of-the-art information on the indications and protocols for CBCT imaging in orthodontics, clinical insights gained from these images, and innovations driven by these insights. As such, it is the most current and authoritative textbook on CBCT in orthodontics. Cone Beam Computed Tomography in Orthodontics is organized to progress sequentially through specific topics so as to build the knowledgebase logically in this important and rapidly evolving field. Part I provides the foundational information on CBCT technology, including radiation exposure and risks, and future evolutions in computed tomography. Part II presents the Principles and Protocols for CBCT Imaging in Orthodontics, focusing on developing evidence-based criteria for CBCT imaging, the medico-legal implications of CBCT to the professional and the protocols and integration of this technology in orthodontic practice. Part III provides critical information on CBCT-based Diagnosis and Treatment Planning that includes how to interpret CBCT scans, identify incidental pathologies and the possible other uses of this technology. Part IV covers practical aspects of CBCT’s Clinical Applications and Treatment Outcomes that encompasses a range of topics, including root morphology and position, treatment of impacted teeth, virtual surgical treatment planning and outcomes, and more.
