Orthodontic mini-implants are able to provide reliable anchorage, but are reported to have varying success (stability) rates. Which factors and issues determine mini-implant success and how can this be maximized? This paper provides an interpretation of the relevant research findings, with a... Read more
This report discusses a case of rare idiopathic root resorption in a 13-year-old female and highlights how an upper standard occlusal radiograph proved to be pivotal in the diagnosis and demonstration of its incidence. Management of the case is described, with discussion of treatment alternatives. Read more
There have been significant changes in the way in which orthodontics has been delivered since the last major workforce study was undertaken. The major change has been the introduction of orthodontic therapists in the UK. This paper aims to outline for the general dental practitioner the role of... Read more
Transpalatal arches (TPAs) are widely used in clinical orthodontics. The versatility of the TPA makes it an extremely useful adjunct to both conventional and contemporary fixed appliance treatment. This paper describes the history, the variety of designs and the clinical steps and laboratory... Read more
The success of orthodontic treatment relies upon careful treatment planning, for both desired and unwanted tooth movement. The theory behind anchorage reinforcement will be considered and the current means of anchorage support and creation will be described. Methods by which the orthodontist can... Read more
6. Vol 8 No 2 P63 Orthodontics: Failure of Eruption of Posterior Teeth by C Dunbar, D Slattery
Failure of eruption of posterior teeth is rare but has significant clinical implications. There has been a recent re-classification of failure of eruption based on aetiology and presentation. Primary failure of eruption (PFE) affects all teeth distal to the affected tooth and can result in a... Read more
A review of the literature outlining the methods of space analysis and their efficacy was completed using PubMed. Four main methods of space analysis in the mixed dentition were explained and the advantages and limitations of each method was outlined. Prediction tables are effective when applied to... Read more
An audit was conducted within a district general hospital’s orthodontic department to improve the quality of digital lateral cephalometric radiographs. The results of the audit show improvements in the quality of lateral cephalometric radiographs, following the introduction of a new picture... Read more
Autism is a developmental disorder that can prove to be a barrier in providing orthodontic care due to a difficulty in developing language and communication. The purpose of legislation imposed in regards to mental capacity is to ensure that an individual has the right to autonomy. However, we must... Read more
Orthodontic plaster casts are fragile and bulky, and an alternative method of storage which allows accurate dental cast measurement is desirable. Four examiners determined the IOTN scores from 30 sets of plaster casts on two occasions and their threedimensional digital equivalents on two occasions.... Read more
For many years, orthodontists have ligated brackets with wire or elastomeric ties. Much of our treatment planning and mechanics have been dictated by a mechanical system incorporating significant amounts of friction. This article will present a nearly friction free system using high-tech brackets... Read more
Advances in orthodontic technology, especially those that address the aesthetic problem of metal or visible braces, have boosted the demand for adult orthodontics. Dental clinicians should be familiar with the advantages and limitations of the new aesthetic appliances coming onto the market. Read more
Clefts of the lip and palate are the most common congenital craniofacial anomaly. They are generally divided into two broad categories, which include cleft lip with or without cleft palate and isolated cleft palate. The incidence of these anomalies varies according to cleft type, geographical... Read more
This paper presents five clinical cases demonstrating the use of the Upper Begg Lower Straight Wire (SWA) technique. It is a method for correcting Class II buccal segments but not involving the classic Begg technique. It frees the occlusion and tips the upper buccal segment teeth distally, and then... Read more
Adult orthodontic demand in the UK has increased significantly in both private and National Health Service sectors, the reason being improvement in the availability of orthodontic services and an increased patient awareness towards orthodontics; in particular the desire for adults to have an...

16. Vol 8 No 1 P5 Editorial Comment: Another year dawns! by J McDonald
The year past was one of continuing tremendous change in the world of orthodontics in the UK – the jury is still out on whether some of the changes were positive, but certainly some have made a significant and lasting impact on our working lives. Read more
Since it is well established that orthodontic mini-implants provide stable anchorage in all three dimensions, the focus has progressed to understanding the related biomechanics. This paper describes the key biomechanical advances for mini-implant treatments, especially in terms of optimized... Read more
18. Vol 7 No 3 P99 Orthodontics: Options to Preserve Teeth Displaced by Dental Cysts by M Cedro
These case reports illustrate the management of two patients presenting with a dentigerous cyst and nasopalatine cyst, respectively. Both patients were treated with different surgical approaches and the associated teeth were successfully aligned with orthodontic appliances. Read more
The aim of this article is to derive an angle using panoramic radiographs which is as reliable as lateral cephalometric norms in determining the skeletal growth pattern. The sample size consisted of 60 OPGs of patients with normodivergent growth pattern evaluated from cephalometric radiographs. The... Read more
Stability of the occlusion after orthodontic treatment is a major goal clinicians set for themselves at the onset of treatment. To achieve this stability, retention becomes a dynamic part of orthodontics. Therefore, this study was conducted to compare and evaluate the effectiveness of Begg... Read more
Orthodontists routinely refer orthodontic patients to either their General Dental Practitioner, for extractions, or to the Maxillofacial team, for extractions plus various surgical procedures. Read more
Discrepancy in vertical tooth positioning may adversely affect anterior dental aesthetics. A simple technique which combines the use of a removable appliance and a composite button can be used effectively for the controlled intrusion of incisors. Read more
Anterior open bites are notoriously difficult to correct. A case is described where a 26-year-old Caucasian female with an anterior open bite, due to a previous persistent digit-sucking habit, is treated successfully with upper and lower fixed appliances and skeletal anchorage to intrude the...

Tooth transposition is the positional interchange of two adjacent teeth or the development or eruption of a tooth in a position occupied normally by a non-adjacent tooth. It has a reported incidence of 0.4% of the population and is more common in females. Canine–premolar transposition is the most... Read more
Magnets have been used in dentistry for many years. The force they deliver can be directed, and they can exert their force through mucosa and bone. There are various types of magnets used in the field of orthodontics and dentofacial orthopaedics, all with their advantages and disadvantages. The... Read more
Soldering is an important routine procedure in orthodontic practice. Stabilization of various wire components during soldering is very important for perfect fitting of an appliance. Read more
The article describes the orthodontic treatment of a 19-year-old female with severe bimaxillary dento-alveolar proclination and severely hyperdivergent jaw bases. Clinical and cephalometric analyses denoted it to be a critical anchorage case. Accordingly, with the aim of providing absolute... Read more
This report presents an interesting case of idiopathic external apical root resorption (IEARR) affecting the non-occluding teeth in a 20-year-old Caucasian male patient with a Class III malocclusion. A review of the current literature is reported and the presenting features of the patient are... Read more
Anterior crossbite or reverse overjet is the term used to describe an abnormal labiolingual relationship between one or more maxillary and mandibular incisor teeth.
