The orthodontic service provision within North Wales, in common with many areas of the United Kingdom, was experiencing increasing waiting times for assessment and treatment. Reasons for this included an increasing population, patient demand and fixed NHS contracted orthodontic provision. In addition to these universal challenges, the geography of North Wales contributed to difficulties in accessing care. It was felt that with a reshaping of the orthodontic services there was potential to enhance the quality of orthodontic care available to patients and deliver prudent NHS orthodontic services...

P Cullingham, A Saksena, M N Pemberton
Over recent years there has been an increased emphasis on improving patient safety in all branches of medicine, with reducing wrong tooth extraction being a priority in dentistry. The true incidence of wrong tooth extraction is unknown but it is considered an avoidable harm and is a significant source of dental litigation. Interventions to reduce wrong tooth extraction include educational programmes encompassing human factor training, patient assisted identification, the use of checklists, marking of surgical sites and implementation of patient safety guidelines...

BACKGROUND: Fixed orthodontic appliances render teeth cleaning arduous, thus when orthodontic treatment is associated with inadequate oral hygiene practice, development of white spot lesions (WSLs) imposes a significant risk on the dentition. Salivary reservoir of calcium, magnesium, phosphorous and fluoride counteracts demineralization and encourages remineralization providing protection against caries challenge. The investigation of the factors leading to WSLs' development is mandatory for appropriate prevention strategies planning...

The main objective of this paper is to propose a novel method that provides an opportunity to evaluate an orthodontic process at early phase of the treatment. This was accomplished by finding out a correlation between the applied orthodontic force and thermal variations in the tooth structure. To this end, geometry of the human tooth surrounded by the connective soft tissue called the periodontal ligament and the bone was constructed by employing dental CT scan images of a specific case. The periodontal ligament was modeled by finite strain viscoelastic model through a nonlinear stress-strain relation (hyperelasticity) and nonlinear stress-time relation (viscoelasticity)...

The conventional orthodontic power chain, often composed of polymer materials, has drawbacks such as a reduction of elasticity owing to water absorption as well as surface discoloration and staining resulting from food or beverages consumed by the patient. The goal of this study was to develop a surface treatment (nanoimprinting) for orthodontic power chains and to alleviate their shortcomings. A concave template (anodic alumina) was manufactured by anodization process using pure aluminum substrate by employing the nanoimprinting process...

PURPOSE OF REVIEW: The article reviews some commonly used orthodontic treatments as well as new strategies to assist in the correction of malocclusion. Many techniques are used in conjunction with surgical intervention and are a necessary compliment to orthognathic surgery. Basic knowledge of these practices will aid in the surgeon's ability to adequately treat the patient. RECENT FINDINGS: Many orthodontists and surgeons are eliminating presurgical orthodontics to adopt a strategy of 'surgery first' orthodontics in orthognathic surgery...
