Correction of Class II division 2 with crowding and bilateral fully transposed impacted mandibular canines

transposition of a canine with an adjacent tooth, aligning the canine into a transposed position can be an accepted option given the likely complexity and duration of the treatment.8,9 An additional challenge for successful management of canine impaction is to regain sufficient space by either extraction or expansion methods. Extraction is commonly used for patients presenting with severe crowding and expansion is applied in patients with mild to moderate crowding. In patients presenting with severe

Maternal Stress Reduces the Susceptibility of Root-Knot Nematodes to Pasteuria Penetrans

maternal effects on host immunity (Hall and Ebert, 2012), two single egg mass lines (SEM) of M. arenaria were evaluated for their response to maternal stress. Materials and methods Rearing females under stressed and non-stressed conditions Females of M. arenaria were exposed to stress from crowding which likely also resulted in low nutritional levels. The experimental design was a 2 × 2 factorial with two treatments (stressed and non-stressed) and two single egg mass (SEM) lines of M. arenaria (SEM

use of removable aligners for orthodontic treatment in which non-extraction therapy is often advocated, the use of IPR becomes a valuable tool to relieve crowding without over-expanding the dental arches. It is possible that inaccurate IPR could result in the over-reduction of enamel, the creation of ledges and notches in the proximal surfaces, increased tooth sensitivity or damage to the surrounding soft tissues. However, carefully conducted IPR performed within the recommended guidelines may be

Arch-dimensional changes in non-extraction cases with finishing wires of a particular material, size and arch form

the University of Melbourne (DHEAG no: 1033997.1). All patients had been treated with fixed appliances (0.018 inch, pre-adjusted edgewise) in the early permanent dentition, without premolar extractions, by one experienced orthodontist. Pre- and post-treatment upper and lower arch dimensions were measured from study casts. Correlation coefficients were calculated between these measurements as well as pretreatment cast and vertical cephalometric measurements, gender and the amount of crowding that

Short-term treatment effects of the quad-helix appliance on dentofacial morphology of hyperdivergent patients

Objectives: The purpose of this study was to evaluate the effects of short-term expansion treatment using the quad-helix appliance on dentofacial morphology in orthodontic patients presenting with a hyperdivergent facial pattern. Methods: The treatment group consisted of 40 patients with a hyperdivergent facial pattern, who were treated for maxillary incisor crowding with a quad-helix appliance during the mixed dentition period. Lateral cephalograms taken at the start (T0) and end (T1) of the

The orthodontic extraction of permanent molars: a literature review

The most common cause of dental crowding is the presence of an arch-length – tooth-size discrepancy. Conventional methods of gaining space in orthodontics involve the extraction of teeth, often premolars. However, there are a number of clinical situations in which the extraction of permanent molars might be considered. This paper highlights the indications, advantages, disadvantages and timing of the extraction of the first, second and third permanent molars in the treatment of a crowded

Interdisciplinary management of a patient with advanced dental needs

The present case report outlines the interdisciplinary management of an adult patient presenting with advanced generalised periodontal attachment loss, an upper dental midline discrepancy following the previous extraction of the upper left central incisor, and significant lower arch crowding. The endodontic and periodontal condition was stabilised prior to the commencement of fixed appliance orthodontic treatment and subsequent prosthetic replacement of the upper left central incisor

Accuracy of predicted versus achieved aligner treatment outcome of a complex case using digital heatmaps

. Once the plan is accepted and the aligners manufactured, the clinician needs to closely monitor the case, employ auxiliary mechanics when necessary, and order additional aligners if required. A decision to extract a lower incisor in orthodontic treatment is based on factors including: Minimal upper incisor and moderate to severe lower incisor crowding. Bilateral Class I or mild Class III molar relationships. An acceptable soft tissue profile. Minimal overbite and overjet. Minimal growth potential

dentition as well as treat an underlying malocclusion. Dental crowding is a common chief complaint expressed by orthodontic patients. The severity of the crowding is an important factor in determining whether to plan extraction or non-extraction treatment. Proffit3 suggested that non-extraction treatment should be considered in cases with less than 4 mm of crowding and extraction treatment when more than 10 mm of crowding was present. This creates a “grey” area of borderline patients who have moderate

Comprehensive periodontal/orthodontic treatment of bimaxillary dentoalveolar protrusion caused by posterior bite collapse due to periodontal disease

Background: Increased mobility of teeth in adult patients with advanced periodontal disease causes posterior bite collapse, which is characterised by mesial inclination of the molars and vertical dimension loss, often resulting in bimaxillary dentoalveolar protrusion. Aim: A case is reported of successful comprehensive periodontal/orthodontic treatment of a 51-year-old woman presenting with bimaxillary dentoalveolar protrusion accompanied by severe crowding in the mandibular arch and flaring of

An Angle Class I malocclusion with a paradental cyst

According to the WHO, a paradental cyst is classified as an odontogenic inflammatory lesion, showing a relative frequency of 0.9–4.7% in the world population. There are no identifiable reports of orthodontic treatment of patients who also present with a paradental cyst. The presenting patient was a Japanese female, aged 16 years and 10 months. The chief complaint was crowding and protrusion of the incisors. The magnitude of the overjet was +4.0 mm, overbite was +3.8 mm, and the intermolar

Multi-disciplinary management of a patient with a post-traumatised incisor presenting concurrent replacement and inflammatory resorption: a case report

This case report describes the multidisciplinary management of a young male who presented with a Class I incisor relationship and bi-maxillary dento-alveolar protrusion on a Class I skeletal base. The occlusion was complicated by an ankylosed and moderately infra-positioned upper left permanent central incisor, an anterior crossbite, crowding, a reduced overbite and centreline discrepancy. The incisor was traumatised and avulsed when the root was immature and the tooth was reimplanted with

The complexity of host-colonizer interactions has led researchers to investigate alternative contexts in pursuit of the mechanism for colonization. Long term care facilities (e.g. nursing homes) constitute communities in which crowding and inadequate hygienic conditions might contribute to higher MSSA (methicillin-sensitive S. aureus) and MRSA (methicillin-resistant S. aureus) prevalence rates.

Results: The majority of patients were female (58.5%), adolescent and had private health insurance (75.6%). The most common patient complaint was crowding (37.6%) and aesthetics (21.3%). Data analysis indicated that 31% of patients were self-referred and a similar proportion did not have a specific complaint. Adult females had a higher interest in aesthetic options.

Results: Statistically significant differences were demonstrated with respect to the arch length, arch shape, total tooth size and arch-length – tooth-size discrepancy (p = 0.03, 0.02, 0.04, 0.01; independent 2-sample t-tests, respectively).

Conclusion: The present case indicated that the timely extraction of palatally-placed maxillary lateral incisors facilitated functional appliance therapy in the management of a skeletal Class II problem. The crowding of the lower anterior teeth was relieved and alignment of the upper arch was achieved with full fixed appliance therapy, resulting in improved aesthetics and a stable occlusion at one year review.
