TL;DR: This review is organized to include all major findings from the beginning of research in the biology of tooth movement, highlights recent developments in cellular, molecular, tissue, and genetic reactions in response to orthodontic force application, and provides insight into the biological background of various deleterious effects of orthodentic forces.

TL;DR: To minimize the failure of screw implants, inflammation around the implant must be controlled, especially for screws placed in the right side of the mandible, as well as local host factors and management factors.

TL;DR: Whether asymmetric and symmetric anterior dental discrepancies are detectable by dental professionals and laypersons is determined and asymmetric alterations make teeth more unattractive to not only dental professionals but also the lay public.

TL;DR: The amount of supplementary mandibular growth appears to be significantly larger if the functional treatment is performed at the pubertal peak in skeletal maturation if theFunctional appliances treated subjects at a prepubertal stage of skeletal maturity.

TL;DR: These data show that the safest location for placing miniscrews might be mesial or distal to the first molar, and an acceptable size of the minISCrew is less than approximately 1.5 mm in diameter and approximately 6 to 8 mm in length.

TL;DR: Findings such as resorption, hyperplasic growth, displacement, shape anomalies of mandibular condyles, and morphological differences between the right and left sides emphasize the diagnostic value of computed tomography acquisitions.

TL;DR: Preliminary results did not indicate that digital models would cause an orthodontist to make a different diagnosis of malocclusion compared with plaster models; digital models are not a compromised choice for treatment planning or diagnosis.

TL;DR: Discovery of mutations in OTM-associated genes of orthodontic patients, including those regulating osteoclast bone-matrix acidification, chloride channel function, and osteoblast-derived mineral and protein matrices, will permit gene therapy to restore normal matrix and protein synthesis and function.

TL;DR: The aim of this article was to describe the advantages and the disadvantages of spiral MS-CT 3D cephalometric method and to discuss the potential of cone-beam CT 3Dcephalometry.

TL;DR: Evaluating periodontal changes by means of computed tomography after rapid maxillary expansion with tooth-tissue-borne and tooth-borne expanders found that the increase in lingual bone plate thickness of the maxillary posterior teeth was greater in the Tooth-borne expansion group than in the tooth-T tissue-borne group.

TL;DR: The distinct characteristic of hypodontia in the Japanese population compared with other populations was a higher prevalence of both advanced hypodentia and mandibular lateral incisor agenesis in children with minor hypodrontia.

TL;DR: It is shown that orthodontic treatment time is influenced by a number of patient characteristics and clinical decisions, and it is possible to predict estimated treatment time for a patient by using a small number of personal characteristics and treatment decisions.

TL;DR: Bracket placement influences the accumulation of plaque and the colonization of important periodontopathic and superinfecting bacteria, resulting in more inflammation and bleeding.

TL;DR: Assessment of the periodontal status of mandibular central incisors that were proclined during orthodontic treatment found recession was negatively correlated with keratinized gingival height and thickness of the facial gingivals margin, and thickness had greater relevance to recession.

TL;DR: Surgical placement of miniscrew implants for orthodontic anchorage in the maxillary molar region requires consideration of the placement site and angle based on anatomical characteristics.

TL;DR: The esthetic impact of malocclusion significantly affects the quality of life of schoolchildren in Belo Horizonte and is associated with negative self-perception of oral esthetics, low self-esteem, and intermediate economic level.

TL;DR: Three-dimensional computed tomography can provide information for use in diagnosis and treatment planning and can be compared with Korean normal averages, and no statistically significant differences were found.

TL;DR: The use of 3D images in the diagnosis of facial asymmetry is described by using the example of a 23-year-old man with a chin deviation to 1 side.

TL;DR: Being used as a screening tool to determine the need for more rigorous ENT follow-up appears to be the greatest utility of lateral cephalograms, and clinicians are advised to look for multiple deviant measures of adenoid size rather than one definitive quantification.

TL;DR: LLLT immediately after multibanding reduced the prevalence of pain perception at 6 and 30 hours and might have positive effects in orthodontic patients not only immediately afterMultibanding, but also for preventing pain during treatment.

TL;DR: The cervical-vertebrae maturation stages are clinically useful maturity indicators of the pubertal growth period TurkishSubjects and the relationship between chronologic age and maturation of cervical vertebrae is investigated.

TL;DR: The results indicate that nonsteroidal anti-inflammatory analgesics such as aspirin and ibuprofen diminish the number of osteoclasts, probably by inhibiting the secretion of prostaglandins, thereby reducing orthodontic tooth movement.

TL;DR: Three methods are described to simulate conventional 2-dimensional cephalograms from CBCT images and volumetric data sets to facilitate the transfer of growth projections from existing data sets as a starting point for use of a new 3-dimensional paradigm.

TL;DR: Smile esthetics among extraction and nonextraction patients and a control group were compared, and certain dentofacial characteristics in those groups were assessed, and how these features relate to smile esthetics were discussed.

TL;DR: The volume of the root resorption craters after intrusion was found to be directly proportional to the magnitude of the intrusive force applied, and differences in the volume was observed from control to light to heavy groups, and these differences were statistically significant.

TL;DR: The SAS is a viable noncompliance modality to move maxillary molars for distally correcting maxillary protrusions and malocclusions characterized by maxillary incisor crowding.

TL;DR: The purposes of this article were to give a brief contemporary overview of the concepts of facial beauty and esthetics and to consider a long-standing and controversial debate on the treatment of patients with dentofacial deformities.

TL;DR: The results showed that the upper pharyngeal width in the subjects with Class I and Class II malocclusions and vertical growth patterns was statistically significantly narrower than in the normal growth-pattern groups.

TL;DR: CPQ(11-14) has acceptable reliability and validity, and is likely to be a useful measure for orthodontic trials, and the impact of malocclusion on a child's quality of life might be substantial.

TL;DR: After long-term use, OAs appear to cause changes in tooth positions that also might affect mandibular posture, and changes in the dentition appeared to be progressive over time.
