Influence of optical properties of esthetic brackets (color, translucence, and fluorescence) on visual perception
Introduction The aims of this study were to evaluate the optical properties of esthetic brackets and determine their influence on visual perception. Methods Eighty esthetic brackets of 16 commercial brands…
Finite element analysis of miniscrew implants used for orthodontic anchorage
Introduction The miniscrew has been developed and effectively used as orthodontic anchorage, but current studies of its usage are insufficient to provide information about the underlying mechanical mechanisms. The aim…
Treatment of ankylosed maxillary central incisors by segmental osteotomy with autogenous bone graft
This case report describes the treatment of a 16-year-old girl with ankylosed maxillary central incisors that were noticeably infraoccluded and labially displaced. We performed a segmental osteotomy with an autogenous…
Modified bonding technique for a standardized and effective indirect bonding procedure
This article describes a modified technique for indirect bonding. Crucial variables that influence the procedure are analyzed and discussed to help the clincian use the indirect bonding techinique routinely. Orthodontists…
En-masse retraction dependent on a temporary skeletal anchorage device without posterior bonding or banding in an adult with severe bidentoalveolar protrusion: Seven years posttreatment
This report describes a novel concept of en-masse retraction with temporary skeletal anchorage devices in place of posterior bonding or banding. The patient was a Korean woman, aged 24 years…
Apical root resorption of incisors after orthodontic treatment of impacted maxillary canines: A radiographic study
Introduction The purpose of the study was to evaluate impacted maxillary canines as risk factor for orthodontic apical root resorption. Methods The sample comprised 66 patients treated with fixed appliances….
Eight-year stability of a severe skeletal anterior open bite with a hyperdivergent growth pattern treated with an edgewise appliance and chin cup therapy
An adolescent boy with an Angle Class II Division 1 malocclusion had a hyperdivergent growth pattern with an excessive lower facial height and an anterior open bite. Combined orthodontic and…
Effect of a low-level laser on bone regeneration after rapid maxillary expansion
Introduction In this study, we evaluated the effects of a low-level laser on bone regeneration in rapid maxillary expansion procedures. Methods Twenty-seven children, aged 8 to 12 years, took part…
New horizons in orthodontics, volume I: Advances in fixed appliance technique
Dr Clarke is a pioneer in functional orthopedic therapy. He continues to develop innovative appliances for orthodontic and orthopedic techniques that have changed clinical practice worldwide. In 1977, he developed…
Relapse of orthodontically corrected deepbites in accordance with growth pattern
Introduction A common orthodontic problem is a deep overbite malocclusion. Because of its high relapse tendency, it is also one of the most challenging problems to treat. To minimize relapse,…
Efficacy of identifying maxillofacial lesions in cone-beam computed tomographs by orthodontists and orthodontic residents with third-party software
Introduction The purpose of this study was to determine the ability of orthodontists and orthodontic residents to identify nonorthodontic incidental findings and false positives in cone-beam computed tomography scans. Methods…
Materiality and materials
A group of readers posted the following comments and questions: As clinicians, we have always been aware of the cytotoxic potential of the intraoral appliances that we place during treatment….
Social media basics for orthodontists
One of the most common buzz words in today’s online world is “social media.” This article defines social media, explains why it is important to practicing orthodontists, and provides information…
Bone damage associated with orthodontic placement of miniscrew implants in an animal model
Introduction The purposes of this study were to quantify bone damage associated with insertion of 2 types of miniscrew implants and to relate the amount of bone damage to monocortical…
Sample calculations for comparison of 2 means
Acommon question in orthodontic research is “how many patients do I need for my study?” The next articles will introduce relevant concepts that will help readers to understand how to…
Dosimetry of a cone-beam computed tomography machine compared with a digital x-ray machine in orthodontic imaging
Introduction Cone-beam computed tomography (CBCT) has become a routine imaging modality for many orthodontic clinics. However, questions remain about the amount of radiation patients are exposed to during the scans….
Real-time cell analysis of the cytotoxicity of orthodontic mini-implants on human gingival fibroblasts and mouse osteoblasts
Introduction The aim of this study was to evaluate the cytotoxic effects of orthodontic mini-implants on gingival fibroblasts and osteoblasts. Methods The orthodontic mini-implants used in this study were Orthodontic…
Cone-beam computed tomography is not the imaging technique of choice for comprehensive orthodontic assessment
It was a pleasure to see that Dr Larson did not take the extreme view of proposing cone-beam computed tomography (CBCT) as a routine diagnostic modality—ie, for every patient, irrespective…
Cone-beam computed tomography is the imaging technique of choice for comprehensive orthodontic assessment
It is interesting to observe the adoption of new technology in dentistry and orthodontics. Of particular interest is the use of cone-beam computed tomography (CBCT) as the imaging protocol of…
