The intrusion of the maxillary first molar is indicated when occlusal clearance is needed for prosthetic rehabilitation. Maxillary molar intrusion may be undertaken using skeletal anchorage systems to avoid complicated mechanics delivered by conventional intra-oral fixed appliances. In the present case report, the efficient use of orthodontic miniscrew anchorage by applying simple mechanics for true maxillary first molar intrusion is described. This was followed by the rehabilitation of the mandibular first molar spaces with implant prostheses...

This report introduces the Hawlix, a hybrid thermoformed and cold-cured retainer. It was developed to overcome the limitations that modified Hawley retainers possess when used in patients with bounded saddles, attributable to dental trauma or hypodontia. The Hawlix can be used as an intermediate retainer while a patient is waiting to receive restorative treatment. Some of the advantages of the Hawlix over the modified Hawley retainer include: superior aesthetics, cost-effectiveness, ease of manufacture, adequate resistance to fracture, preservation of a residual ridge, and precise space maintenance...

INTRODUCTION: A considered space analysis aims to predict the combined mesiodistal widths of unerupted permanent canine and premolars. A miscalculation can lead to the application of inadequate and irreversible treatments. OBJECTIVE: To assess the level of agreement between predictions generated by three methods (Moyers' predictive tables at the 50th and 75th percentiles and Tanaka-Johnston's equations) on the sum of unerupted teeth compared with measurements derived from cone beam computed tomography, considered in the present study as a 'gold standard'...

This paper questions the adequacy of orthodontists' full appreciation of the issues associated with the routine prescription of extra- oral radiography, particularly that related to a high risk of thyroid gland exposure to ionising radiation. There does not appear to be adequate application of the ALARA principle in the consileration of justifiable options to minimise the cumulative effects of radiation exposure in young patients.

INTRODUCTION: The validity, reliability and inter-method agreement of Peer Assessment Scores (PAR) from acrylic models and their digital analogues were assessed. METHOD: Ten models of different occlusions were digitised, using a 3 Shape R700 laser scanner (Copenhagen, Denmark). Each set of models was conventionally and digitally PAR-scored twice in random order by 10 examiners. The minimum time between repeat measurements was two weeks. The repeatability was assessed by applying Carstensen's analysis...

INTRODUCTION: Neural crest cells make up a transient migratory population of cells found in all vertebrate embryos. Great advances have been made over the past 20 years in clarifying the molecular basis of neural crest induction and, although much still remains unclear, it appears that it is a process involving several factors acting at different stages of embryogenesis. In the future, an understanding of the precise mechanisms involved in orofacial development, even at the earliest stages, may well be of use to all clinicians interested in the management of these tissues...

BACKGROUND: Titanium alloy mini-implants have become popular in recent times and have been extensively used and studied. Although corrosion resistance of orthodontic materials has always been of concern, this property has been the least explored. The present study aimed to assess the composition, surface characterisation and corrosion resistance of five commercially available mini-implants by assaying ion release in artificial saliva. METHODS: Ten mini-implants each from five companies were obtained: Group 1 - AbsoAnchor (Dentos Inc, South Korea); Group 2 - Microimplant Anchorage System (MIA, Biomaterials Korea); Group 3 - The Orthodontic Mini Anchorage System (TOMAS, Dentaurum, Germany); Group 4 - mini-implants (Denticon, Maharashtra, India); Group 5 - orthodontic mini-implants (lJ...

For some years there has been unrest in the statistical world regarding the use of the p-value. It has been indicated that the significance of p-values is open to question, which therefore reduces the ability to measure the strength of evidence. This paper examines the use and misuse of the p-value and recommends consideration in its application.

Samuel C Bennett, Mithran S Goonewardene
BACKGROUND: Hemimandibular hyperplasia (HH), also known as hemimandibular hypertrophy, is characterised by excessive unilateral three-dimensional growth of the mandible after birth. Vertical unilateral elongation of the mandible becomes clinically evident as a rare form of vertical facial asymmetry. Aberrant growth of the facial skeleton affects the developing dentition and the dental compensatory mechanism is usually unable to maintain optimal occlusal relationships. The resulting malocclusion is effectively managed by combined surgical-orthodontic care to address the facial, skeletal and dental problems that confront clinicians...
